RESUMEN

OBJECTIVES: This study evaluated the occupational injuries and health hazards associated with fishing as an occupation among non-traditional rural tribal fishing communities in the coastal region of Tamil Nadu, India. METHODS: This cross-sectional study included a total of 170 individuals belonging to a fishing community, comprising both male (n = 82) and female (n = 88) participants. The demographic details including occupational history, lifestyle characteristics, socio-economic status, personal habits, and health status were assessed through the questionnaire survey. RESULTS: The fishing community has a low socioeconomic status and poor literacy, lifestyle, and personal habits. The mean age of the participants was 38.8 yrs (male 34.8; female 39.9 yrs). Only 10% reported usage of personal protective equipment (PPE), and the work duration varied from 8 to 24 hrs in a day. While male subjects reported smoking habits (12%) and alcohol consumption (23%), none of the females reported alcohol consumption and smoking habits. The major occupational injuries that occurred were due to catfish (72%) and oysters (48%). A large number of female subjects reported musculoskeletal pains. The body mass index of about 28% of fishermen was above the normal range. Abnormal blood sugar, blood pressure, and respiratory and neurological symptoms were the other major health complaints. The major environmental hazards reported were salinity, solar radiation, tides, and high wind. CONCLUSION: Injuries from handling fish and oysters were observed to be the major occupational burden. Additonally, a high prevalence of musculoskeletal pain and chronic health illness was commonly observed among the fishers. Adequate training and awareness programs are required for effective management of occupational health hazards and health promotion.

RESUMEN

OBJECTIVES: This systematic review aims to qualitatively synthesize existing evidence on the efficacy of HIV interventions in African fishing communities. METHODS: Five databases (NCBI PubMed, EMBASE, Web of Science Core Collection, The Cochrane Library, and CABI Global Health Database) were searched in March 2019 for eligible studies. All peer-reviewed papers with a defined HIV intervention explicitly mentioning African fishing communities were included. Outcomes included any measure of the efficacy of HIV interventions. RESULTS: Of 22,289 search results, data was extracted from 25 eligible studies that passed critical appraisal; seven involved HIV prevention, six HIV testing and counseling, three treatment, and nine combinations of more than one intervention. Findings include a high coverage of safe male circumcision (SMC) but low condom use among fisher folk, and a preference for PrEP over other HIV prevention services. Uptake of HIV testing and ART coverage are below levels required to reach UNAIDS 90-90-90 targets, and there is a high demand for ART and HIV self-testing kits. CONCLUSIONS: Greater provision of services to combat HIV, specifically amongst fishing communities, is required; there is limited information on retaining fisher folk in care and achieving an undetectable viral load. Interventions tailored to individual fishing populations, offered in parallel to education or counseling services are likely to be most effective. Use of innovations, including mobile health and medical drones, could assist these hard-to-reach populations. Our findings will inform future HIV service provision in fishing communities.

RESUMEN

Recruitment is one of the dominant processes regulating fish population productivity. It is, however, notoriously difficult to predict, as it is the result of a complex multi-step process. Various fine-scale drivers might act on the pathway from adult population characteristics to spawning behaviour and egg production, and then to recruitment. Here, we provide a holistic analysis of the Northwest Atlantic mackerel recruitment process from 1982 to 2017 and exemplify why broad-scale recruitment-environment relationships could become unstable over time. Various demographic and environmental drivers had a synergetic effect on recruitment, but larval survival through a spatio-temporal match with prey was shown to be the key process. Recruitment was also mediated by maternal effects and a parent-offspring fitness trade-off due to the different feeding regimes of adults and larvae. A mismatch curtails the effects of high larval prey densities, so that despite the abundance of food in recent years, recruitment was relatively low and the pre-existing relationship with overall prey abundance broke down. Our results reaffirm major recruitment hypotheses and demonstrate the importance of fine-scale processes along the recruitment pathway, helping to improve recruitment predictions and potentially fisheries management.

RESUMEN

Background: Falls overboard are the most frequent cause of death in the Northeast lobster fishing industry. National Institute for Occupational Safety and Health (NIOSH) surveillance indicates every victim of a fall overboard who has been found was not wearing a lifejacket. Preliminary research conducted in Maine and Massachusetts indicates lifejacket use is relatively uncommon among lobstermen due to barriers such as comfort, practicality, and social norms.Methods: This study highlights an initiative to: (1) trial various lifejacket designs with lobstermen; (2) identify the most popular designs; and (3) identify other features that could encourage use of lifejackets. In 2017, nine designs were trialed with lobstermen in Maine and Massachusetts during the winter and summer fishing seasons. Participants were recruited dockside, and lifejackets were randomly assigned. Participants completed surveys at 1 week and 4 weeks to assess positive and negative design features and to understand the importance of survival technology that can be used in conjunction with lifejackets.Results: 181 lobstermen in Maine and Massachusetts agreed to participate. Recruitment rates were 90.5%, while the survey completion rate was 88.4%. Survey results identified no clear preference for a specific lifejacket design; however, the ability to choose from many options appeared to be an important factor.Conclusion: Previous studies have indicated that lifejacket preferences are fisheries specific. In the Northeast lobster fishery, however, individual preferences varied. Our research demonstrates that a range of devices covering different buoyancies, wear type, and retrieval systems should be made more available to lobstermen.

RESUMEN

Objectives: The study objective was to estimate a denominator of exposure to inshore lobstering in Full-Time Equivalents (FTEs), to count incident injury data from a sample cohort of this population, to use this count to calculate rates for incident injuries, and to use official counts of fatalities to estimate a fatality rate.Methods: Captains were randomly selected from those licensed to fish in Maine and Massachusetts. Data on work exposure and injuries that occurred on the boat were collected using a survey that was administered once per season via phone or face-to-face interview with the captain. Data included self-reports of the number of weeks worked during the season, average crew size, number of trips per week, and average trip length in hours. In addition, this survey captured relevant information (body segment affected, type of injury, and whether treatment was received) on all acute injuries occurring during the season. Only data on acute injuries were collected, and defined as having newly occurred within the last 3 months. Counts of fatalities were obtained from an official surveillance database at the National Institute for Occupational Health and Safety.Results: The total occupational exposure reported for the cohort was over 2 million man-hours over 4 years, resulting in an average annual FTE of 5,847. The fatality rate averaged over 4 years was 21/100,000 FTE. The incidence rates for all injuries (51.0/100 FTE) and injuries receiving treatment (17.5/100 FTE) were much higher than those reported in other studies of fishing that used US Coast Guard data. Lobstermen presented with all categories of injuries, sprains being the most frequent (7.8/100 FTE) and amputations the least (0.2/100 FTE). Wrist/hand injuries on the right side occurred most frequently of all body locations (3.6/100 FTE).Conclusion: Non-fatal injuries occur at high rates in lobstering. The impact of interventions aimed at exposure to risk for sprains and cuts has potential to affect the most lobstermen. Fatality rate appears to have been unchanging since the year 2000.

RESUMEN

Coastal Indigenous peoples rely on ocean resources and are highly vulnerable to ecosystem and economic change. Their challenges have been observed and recognized at local and regional scales, yet there are no global-scale analyses to inform international policies. We compile available data for over 1,900 coastal Indigenous communities around the world representing 27 million people across 87 countries. Based on available data at local and regional levels, we estimate a total global yearly seafood consumption of 2.1 million (1.5 million-2.8 million) metric tonnes by coastal Indigenous peoples, equal to around 2% of global yearly commercial fisheries catch. Results reflect the crucial role of seafood for these communities; on average, consumption per capita is 15 times higher than non-Indigenous country populations. These findings contribute to an urgently needed sense of scale to coastal Indigenous issues, and will hopefully prompt increased recognition and directed research regarding the marine knowledge and resource needs of Indigenous peoples. Marine resources are crucial to the continued existence of coastal Indigenous peoples, and their needs must be explicitly incorporated into management policies.

RESUMEN

BACKGROUND: Data derived from studies of fishers' local ecological knowledge (LEK) can be invaluable to the proposal of new studies and more appropriate management strategies. This study analyzed the fisher's LEK about trophic relationships of fishes in the southeastern Brazilian coast, comparing fishers' LEK with scientific knowledge to provide new hypotheses. METHODS: The initial contacts with fishers were made through informal visits in their residences, to explain the research goals, meet fishers and their families, check the number of resident fishers and ask for fishers' consent to participate in the research. After this initial contact, fishers were selected to be included in the interviews through the technique of snowball sampling. The fishers indicated by others who attended the criteria to be included in the research were interviewed by using a semi-structured standard questionnaire. RESULTS: There were interviewed 26 artisanal fishers from three communities of the Ilhabela: Jabaquara, Fome and Serraria. The interviewed fishers showed a detailed knowledge about the trophic interactions of the studied coastal fishes, as fishers mentioned 17 food items for these fishes and six fish and three mammals as fish predators. The most mentioned food items were small fish, shrimps and crabs, while the most mentioned predators were large reef fishes. Fishers also mentioned some predators, such as sea otters, that have not been reported by the biological literature and are poorly known. CONCLUSIONS: The LEK of the studied fishers showed a high degree of concordance with the scientific literature regarding fish diet. This study evidenced the value of fishers' LEK to improve fisheries research and management, as well as the needy to increase the collaboration among managers, biologists and fishers.

RESUMEN

We examined the geographic extent of petroleum hydrocarbon contamination in sediment, seawater, biota, and seafood during/after the BP/Deepwater Horizon Oil Spill (April 20-July 15, 2010; 28.736667°N, -88.386944°W). TPH, PAHs, and 12 compound classes were examined, particularly C1-benzo(a)anthracenes/chrysenes, C-2-/C-4-phenanthrenes/anthracenes, and C3-naphthalenes. Sediment TPH, PAHs, and all classes peaked near Pensacola, Florida, and Galveston, Texas. Seawater TPH peaked off Pensacola; all of the above classes peaked off the Mississippi River, Louisiana and Galveston. Biota TPH and PAHs peaked near the Mississippi River; C-3 napthalenes peaked near the spill site. Seafood TPH peaked near the spill site, with PAHs and all classes peaking near Pensacola. We recommend that oil concentrations continued to be monitored in these media well after the spill has ceased to assist in defining re-opening dates for fisheries; closures should be maintained until hydrocarbon levels are deemed within appropriate limits.

RESUMEN

INTRODUCTION: Accidents caused by fish are common in inland fishing communities in Brazil, being work-related injuries in the majority of cases. These populations have no information on the mechanisms of trauma or envenoming. METHODS: Through a questionnaire administered to fishermen, we obtained clinical and epidemiological data on accidents in Rosana, Pontal do Paranapanema, State of São Paulo, Brazil. These data were analyzed and converted into an easily understood prevention and treatment program for the colony. RESULTS: Thirty-nine fishermen replied to the survey. All of the patients had been hurt by fish. Of those mentioned, the yellow catfish (Pimelodus maculatus) was the main fish species associated with injuries, but others also caused trauma to the fishermen. Six fishermen had been envenomed by stingrays. Pain and ulcers were the main symptoms and were described as intolerable. Approximately half of those injured were treated using traditional folk remedies. CONCLUSIONS: The fishermen suffered multiple accidents with catfish, which are venomous and cause intense pain, as well as trauma due to other fish, such as surubins, traíras, freshwater croakers, and piranhas. Approximately 16% of those interviewed presented with envenomation from stingrays. Our data and previous experience in the area led to the creation of a pamphlet with clear language that can effectively help fishermen in the region, an area in need of health services and disease prevention. This initiative also applies to the whole La Plata River basin, which has similar fauna.

INTRODUÇÃO: Os acidentes causados por peixes são comuns em comunidades de pescadores fluviais no Brasil, sendo acidentes ocupacionais na maioria das vezes. Estas populações não têm informações dos mecanismos de trauma e envenenamento. MÉTODOS: Através de um questionário aplicado aos pescadores, foram obtidos dados clínicos e epidemiológicos sobre acidentes em Rosana, Pontal do Paranapanema, Estado de São Paulo, Brasil. Estes dados foram analisados e convertidos em um programa de prevenção e tratamento de acidentes através de um folheto de fácil assimilação RESULTADOS: Trinta e nove pescadores responderam o questionário. Todos os pacientes apresentaram ferimentos causados por algum peixe. Dos peixes mencionados, mandijubas (Pimelodus maculatus) foram os mais associados aos ferimentos, mas outros também causaram traumas. Em relação às arraias, seis pescadores tinham sido envenenados. Dor intensa e úlceras foram os principais sintomas. Aproximadamente metade dos acidentados usou apenas medidas de tratamentos populares. CONCLUSÕES: Os pescadores apresentaram acidentes múltiplos por mandis, que são peçonhentos e causam dor intensa, assim como traumas por outros peixes, como surubins, traíras, corvinas de água doce e piranhas. Cerca de 16% dos entrevistados apresentaram envenenamento por arraias. Nossos dados e experiência prévia permitiram a criação de um folheto de fácil assimilação pelas populações locais que pode ajudar os pescadores de forma efetiva, em uma área extremamente carente de serviços de saúde e prevenção de doenças. Esta iniciativa é aplicável a toda a bacia do Rio da Prata, área extensa e de fauna similar.

RESUMEN

Accurate information on total catch and effort is essential for successful fisheries management. Officially reported landings, however, may be underestimates of total catch in many fisheries. We investigated the fishery for the nationally red-listed European lobster (Homarus gammarus) in south-eastern Norway. Probability-based strip transect surveys were used to count buoys in the study area in combination with catch per unit effort data obtained independently from volunteer catch diaries, phone interviews, and questionnaires. We estimate that recreational catch accounts for 65% of total catch in the study area. Moreover, our results indicate that only a small proportion (24%) of lobsters landed commercially were sold through the legal market and documented. Total estimated lobster catch was nearly 14 times higher than reported officially. Our study highlights the need for adequate catch monitoring and data collection efforts in coastal areas, presents a clear warning to resource managers that illegal, unreported and unregulated (IUU) fisheries in coastal areas should not be ignored, and shows the potential impact of recreational fisheries.

RESUMEN

Unsustainable fishing simplifies food chains and, as with aquaculture, can result in reliance on a few economically valuable species. This lack of diversity may increase risks of ecological and economic disruptions. Centuries of intense fishing have extirpated most apex predators in the Gulf of Maine (United States and Canada), effectively creating an American lobster (Homarus americanus) monoculture. Over the past 20 years, the economic diversity of marine resources harvested in Maine has declined by almost 70%. Today, over 80% of the value of Maine's fish and seafood landings is from highly abundant lobsters. Inflation-corrected income from lobsters in Maine has steadily increased by nearly 400% since 1985. Fisheries managers, policy makers, and fishers view this as a success. However, such lucrative monocultures increase the social and ecological consequences of future declines in lobsters. In southern New England, disease and stresses related to increases in ocean temperature resulted in more than a 70% decline in lobster abundance, prompting managers to propose closing that fishery. A similar collapse in Maine could fundamentally disrupt the social and economic foundation of its coast. We suggest the current success of Maine's lobster fishery is a gilded trap. Gilded traps are a type of social trap in which collective actions resulting from economically attractive opportunities outweigh concerns over associated social and ecological risks or consequences. Large financial gain creates a strong reinforcing feedback that deepens the trap. Avoiding or escaping gilded traps requires managing for increased biological and economic diversity. This is difficult to do prior to a crisis while financial incentives for maintaining the status quo are large. The long-term challenge is to shift fisheries management away from single species toward integrated social-ecological approaches that diversify local ecosystems, societies, and economies.

RESUMEN

BACKGROUND, AIM, AND SCOPE: The aim of the present study was to evaluate the distribution of petroleum hydrocarbons in ten commercial fish species and water samples in three estuaries along Tamilnadu coast, Bay of Bengal, India. MATERIALS AND METHODS: Fish and water samples collected from Tamilnadu coast, India, were extracted and analyzed for petroleum hydrocarbons by ultraviolet fluorescence (UVF) spectroscopy. RESULTS: The petroleum hydrocarbon concentration (PHC) in coastal waters and fish species varied between 2.28 and 14.02 µg/l and 0.52 and 2.05 µg/g, respectively. The highest PHC concentration was obtained in Uppanar estuarine waters (14.02 ± 0.83) and the lowest was observed in Vellar estuarine waters (2.28 ± 0.25). DISCUSSION: Among the ten fish species, Sardinella longiceps have high PHC concentration from all the locations. This study suggests that S. longiceps can be used as a good biological indicator for petroleum hydrocarbon pollution in water. CONCLUSIONS: The concentration of petroleum hydrocarbons in coastal waters along Tamilnadu coast is markedly higher than that in the background, but there is no evidence for its increase in fish of this region. From a public health point, petroleum hydrocarbon residue levels in all fish samples analyzed in this study are considerably lower than the hazardous levels. RECOMMENDATIONS AND PERSPECTIVES: At present, as Tamilnadu coastal area is in a rapid development stage of new harbour, chemical industries, power plants, oil exploration and other large-scale industries, further assessment of petroleum hydrocarbons and the various hydrodynamic conditions acting in the region are to be studied in detail and continuous pollution monitoring studies should be conducted for improving the aquatic environment. The results will also be useful for pollution monitoring program along the coastal region and also to check the levels of petroleum hydrocarbons.

RESUMEN

An adaptation of the Drivers-Pressure-State-Impact-Response methodology is presented in this work. The differential DPSIR (DeltaDPSIR) was developed to evaluate impacts on the coastal environment and as a tool for integrated ecosystem management. The aim of the DeltaDPSIR is to provide scientifically-based information required by managers and decision-makers to evaluate previously adopted policies, as well as future response scenarios. The innovation of the present approach is to provide an explicit link between ecological and economic information related to the use and management of a coastal ecosystem within a specific timeframe. The application of DeltaDPSIR is illustrated through an analysis of developments in a Southwest European coastal lagoon between 1985 and 1995. The value of economic activities dependent on the lagoon suffered a significant reduction (ca. -60%) over that period, mainly due to a decrease in bivalve production. During that decade the pressures from the catchment area were managed (ca. 176 million Euros), mainly through the building of waste water treatment plants. Notwithstanding this, the ecosystem state worsened with respect to abnormal clam mortalities due to a parasite infection and to benthic eutrophication symptoms in specific problematic areas. The negative economic impacts during the decade were estimated between -565 and -315 million Euros, of which 9-49% represent the cost of environmental externalities. Evaluation of these past events indicates that future management actions should focus on reducing the limitation on local clam seeds, which should result in positive impacts to both the local socio-economy and biodiversity.

RESUMEN

Lake Mariut was considered in the past to represent an important source of fish production in Alexandria especially during the periods which were characterized by low catch from its marine fisheries. The growing population in Alexandria and the expanding industries around the lake were accompanied with increased quantities of domestic and industrial wastes discharged annually into the lake proper. These quantities were increased from 192 million cubic meters in 1974 to about 300 million cubic meters in 1992. Consequently, the water quality in this basin was highly deteriorated and changed to become markedly eutrophic. High input of nutrients through sewage and industrial wastes has considerably increased the phosphorus and nitrogen load in the lake proper. Phosphorus and nitrogen loading in this basin were estimated in 1992 to be 60.2 gm/m3 P/y and 79.8 gm/m3 N/y. According to the nutrient concept given by Vollenweider (1974), these two figures have provided an evidence that the lake proper was strongly changed from oligotrophic to polytrophic phase. The trend of its total fish catch as well as the trend of different fish categories catch during the period 1970-1992 also confirms its eutrophication. This is in addition to bad changes that took place with respect to environmental conditions due to the continuous inflow of domestic and industrial wastes from different sources into this part of Mariut lake. Marginal increments of the lake proper total catch were decreased from 20.6% in 1970 to -28.8% in 1992, while the marginal increments of Tilapia sp., Clarias sp, Anguilla sp. and Mugil sp. were decreased from 21.4%, 14.3%, 29.8%, and 28.9% respectively in 1970 to -29.1%, -25.3%, -43.0%, and -36.8% in 1992. Based on these two indices of the lake proper eutrophication, the expected improvement of its environmental conditions will take several years after treating all inland discharges flowing into the lake and/or diverting all relevant outfalls away from this basin.
