Patterns in fish naming ability in two fishing communities of Myanmar.

BACKGROUND: To date, there is little reliable information on the fish names used by two fishing communities of Myanmar, namely Intha (Inle Lake) and Rakhine (Bay of Bengal). Moreover, there have been no systematic studies on the distribution of fish-related traditional knowledge in these two communities. As there can be high levels of intra-community variation in traditional ecological knowledge, it is important to investigate this variation along the lines of key social variables. METHODS: Fieldwork was carried out in both communities and involved the presentation of visual stimuli (colour pictures of locally relevant fish species) to respondents, and asking for a name in the local language. The stimuli consisted of 43 and 218 fish species for Intha and Rakhine, respectively. The responses were analysed in terms of respondent age and occupation for both communities, plus village location for Intha and gender whenever both genders were represented in a sufficiently large number in the sample. RESULTS: Fish name lists were generated for both languages, taking into account lexical variation, as well as the number of people able to name each fish. The two communities differed markedly in the way fish knowledge was distributed. Overall, younger Intha knew fewer fish names, but there was little to no difference in fish knowledge among the Intha on the basis of occupation, location or gender. In contrast, the differences were very marked among Rakhine respondents. CONCLUSIONS: The reduced fish knowledge of younger Intha may be ascribed to environmental disturbances that have caused many fish to go locally extinct. The otherwise homogenous distribution of fish knowledge in the Intha community may be due to the small number of species that people are required to learn. This idea needs to be tested with a larger sample of respondents. Among the Rakhine, a number of factors are responsible for the observed variation; these include a steep learning curve among younger fishermen, the difference in fish species encountered by fishermen and sellers, highly variable dietary preferences among the general populace and differing gender roles in the context of market visits. The authors are in full agreement with previous research that advocates a variationist approach to the study of traditional ecological knowledge.

Prevalence of Musculoskeletal Disorders and Self-Reported Pain in Artisanal Fishermen from a Traditional Community in Todos-os-Santos Bay, Bahia, Brazil.

Musculoskeletal disorders (MSDs) can be characterized from their occupational etiology and their occurrence; their chronicity generates negative repercussions for the health of workers, especially of artisanal fishing. To investigate the prevalence of generalized musculoskeletal disorders by body region and self-reported pain in a fishing population of northeastern Brazil, an epidemiological cross-sectional study was carried out in Santiago do Iguape, Bahia-Brazil, in 2017. The Brazilian version of the Nordic Musculoskeletal Questionnaire (NMQ), in addition to a questionnaire containing the socio-demographic and labor conditions were applied to a random stratified sample of 248 artisanal fisheries. There were 170 female shellfish gatherers and 78 fishermen, with a mean age of 36.7 years (SD = 10.5 years) and 43.3 years (SD = 11.8 years), respectively. The beginning of the labor activity was initiated at approximately 11 years of age. The average weekly income varied from 17.64 USD to 29.10 USD. The prevalence of MSD independent of occupation occurred in at least one body region in 93.5% and the presence of musculoskeletal pain/discomfort over the last seven days in 95.2% of the fishing workers. The highest prevalence of MSD was found in shellfish gatherers in: lower back (86.4%), wrist and hand (73.5%), and upper back (66.8%). In relation to the presence of pain in the last year, the frequency of pain was greater in the fishermen compared to the shellfish gatherers. The generalized severity of the MSD in 93.5% of this community of fishermen is evident, with emphasis in the following regions: lower back, wrist and hand and upper back in both groups, with occurrence of pain in more than one body region at the same time.

Preliminary assessment of the impact of Covid-19 Pandemic in the small-scale and recreational fisheries of the Canary Islands.

Covid-19 pandemic has affected worldwide in many different ways. Fisheries around the world are not an exception due to the long-term isolation and the non-activities period suffered. To do an evaluation of its impact on the fishing sectors in the Canary Islands, 87 online and phone questionnaires were carried out between July and September 2020, conducting the interviews to artisanal fishermen, fishmongers, recreational charter boats fishermen and tackle shops along the archipelago. Both, the artisanal and recreational fishing sectors have been affected by this pandemic, but in an unequal manner. The drop of the demand of fresh fishing products in the islands markets due to the closure of hotels, restaurants and other services, and the highly significant decreasing in the number of tourists, provoked an estimated income loss for the artisanal fishermen about the 40% on average, but the majority of vessels continued their activities during the pandemic, with very limited effects on direct employment. However, the fishmonger's activity apparently was not affected and increased their monthly income in relation to the previous year. Likewise, the infeasibility of fishing charter companies due to the great reduction in the number of tourists contrasted with the significant increase in the number of recreational fishing licenses immediately after the confinement ended. Even though that fishing tackle shops increased sales by over 60% in relation to the similar period of the year before, only 4.4% of these shops declared not to have had economic losses.

Ornamental fishing in the region of Barcelos, Amazonas: socioeconomic description and scenario of activity in the view of piabeiros / A pesca ornamental na região de Barcelos, Amazonas: descrição socieconômica e cenário da atividade na visão dos piabeiros

Abstract The Negro river basin is considered the largest area of extractive of ornamental fish in Brazil. This area has fundamental importance for the populations from the Amazon. The present study aimed to describe socioeconomic profile of ornamental fishermen known as "piabeiros" in the Municipality of Barcelos, as well as the ornamental fishery, fisheries area, target species, environments, fishing techniques, equipment, capture techniques and main difficulties faced by the current activity. This study was carried out in municipality of Barcelos, through semi - structured interviews, with artisanal ornamental fishermen (N= 89). The main families of ornamental fish caught and traded were: Characidae, Lebiasinidae, Gasteropelecidae, Cichilidae, Anostomidae, Loricaridae, Potamotrygonidae and Gymnotidae. The main catchment areas were igarapés, lakes, flooded fields, beaches, river banks and igapó forest. Rapiché was the most used equipment in the fisheries both by the fishermen of the urban areas (43.81%) and rural (41.89%). Most of the fishermen are associated with the colony of fishermen of Barcelos (Z33). The data showed that the dynamics of ornamental fishing have changed in a short time and directly affected fishermen, in addition to the low age renewal with the participation of younger fishermen, threatening the transmission of ecological knowledge to future generations. As a result, the increase of the problems related to the productive chain and absence of public power to the activity, since ornamental fishing has already been treated as one of the main economic activities more important for the local communities and for the State of Amazonas.

Resumo A bacia do rio Negro é considerada a maior área de extrativismo de peixes ornamentais do Brasil. Esta área possui importância fundamental para as populações da Amazônia. O presente estudo objetivou descrever o perfil socioeconômico de pescadores conhecidos como "piabeiros" no município de Barcelos, bem como a pesca ornamental, área de pesca, espécies-alvo, ambientes, técnicas de pesca, equipamentos, técnicas de captura e dificuldades enfrentadas nesta atividade. O estudo foi realizado por meio de entrevistas semi - estruturadas, com pescadores artesanais ornamentais (N= 89). Os dados mostram que as famílias de peixes ornamentais capturados e comercializados foram: Characidae, Lebiasinidae, Gasteropelecidae, Cichilidae, Anostomidae, Loricaridae, Potamotrygonidae e Gymnotidae. As áreas de captura descritas foram igarapés, lagos, alagados, praias, margens de rios e floresta de igapó. O Rapiché foi o equipamento mais utilizado nas pescarias tanto pelos pescadores das áreas urbanas (43,81%) como rurais (41,89%). A maioria dos pescadores está associada à colônia de pescadores de Barcelos (Z33). Os dados coletados mostraram que a dinâmica da pesca ornamental mudou em pouco tempo e afetou diretamente os pescadores. Além da baixa taxa de renovação, com a participação de pescadores mais jovens, ameaçando a transmissão de conhecimento ecológico para as gerações futuras. Como resultado, notamos o aumento dos problemas relacionados à cadeia produtiva e a ausência de poder público na atividade. A pesca ornamental já foi tratada como uma das principais atividades econômicas para as comunidades locais e para o Estado do Amazonas.

Determinants of credit constraint of artisanal fishermen in Ghana / Determinantes da restrição de crédito a pescadores artesanais em Gana

ABSTRACT: Due to the high risk associated with fishing, access to credit becomes very difficult for fishermen. The study was conducted to investigate the determinants of credit constraint on artisanal fishermen with survey data collected from artisanal fishermen in the Western and Central Regions of Ghana. A multi-stage sampling procedure was used to select respondents for the study. Data collected were analyzed with the aid of descriptive and IV-Probit model. Most of the fishermen were in their youthful stage. From the study, while boat ownership and off-fishing activity reduce the probability being credit constrained, complex procedure, and disbursement time lag increase fishermen probability of being credit constrained. The findings of the study also indicated that there is a significant difference between constrained and unconstrained fishermen fishing activity and financial status. Therefore, fishermen in need of additional credit should be catered for to increase their production, hence, livelihood.

RESUMO: Devido ao alto risco associado à pesca, o acesso ao crédito se torna muito difícil para os pescadores. O estudo foi conduzido para investigar os determinantes da restrição de crédito em pescadores artesanais com dados de pesquisa coletados nas regiões oeste e central de Gana. Um procedimento de amostragem em vários estágios foi usado para selecionar os entrevistados para o estudo. Os dados coletados foram analisados com o auxílio do modelo descritivo e IV-Probit. A maioria dos pescadores estava em sua fase juvenil. A partir do estudo, enquanto a propriedade do barco e a atividade fora da pesca reduzem a probabilidade de restrição de crédito, procedimentos complexos e atraso no desembolso aumentam a probabilidade dos pescadores sofrerem restrição de crédito. Os resultados do estudo também indicaram que há uma diferença significativa entre a atividade pesqueira e a situação financeira dos pescadores com e sem restrição. Portanto, os pescadores que precisam de crédito adicional devem ser atendidos para aumentar sua produção e, portanto, meios de subsistência.

Capturas de la raya Dasyatis longa (Myliobatiformes: Dasyatidae) en las pesquerías artesanales de Golfo Dulce, Costa Rica / Longtail stingray Dasyatis longa, (Myliobatiformes: Dasyatidae) catches in the artisanal fisheries of Golfo Dulce, Costa Rica

Resumen Entre mayo 2010 y mayo 2011 se analizaron las rayas látigo (Dasytis longa) capturadas por pescadores artesanales de Golfo Dulce, Pacífico Sur de Costa Rica. En total se realizaron 30 faenas en diferentes zonas con fondos lodosos y rocosos de baja profundidad (menos de 30m). Durante las 30 faenas de pesca se capturaron 872 organismos, de estos, 112 (13.1%) fueron rayas. La especie más abundante fue D. longa, aportando el 75.7% de las rayas y más del 10% de la captura total. Los análisis revelaron una proporción sexual de 1.33 machos por cada hembra para las rayas látigo y una longitud media del ancho del disco de 84.63±12.11cm. Con respecto a la captura por unidad de esfuerzo (CPUE), las mayores CPUE se obtuvieron en enero y febrero que se capturaron en promedio de 0.006 rayas látigo por anzuelo por hora. La condición de captura, el bajo valor comercial y la disponibilidad de los pescadores, permitió liberar el 99% de las rayas capturadas. Debido a la alta sobrevivencia y capturas de D. longa en las pesquerías artesanales, se recomienda regular la línea de fondo durante enero-febrero en Los Bajos, Pique Fijo y La Ciénaga (Zona externa Golfo Dulce).

Abstract From May 2010 until May 2011, the longtail stingrays (Dasytis longa), caught by artisanal fishermen in Golfo Dulce, south Pacific of Costa Rica, were analyzed. We observed a total of 30 artisanal fishing operations in different areas of Golfo Dulce, with muddy bottoms and very shallow waters (less than 30m). The areas called "Los Bajos" and "Pique Fijo" represented the 26.7% and 23.3% of all the operations, respectively. Other important areas were "La Cienaga" (20.0%), "Lapa-Ríos" (6.7%) "Piedra del Sombrero" (6.7%) and "Pavones" (6.7%). "Matapalo", "Corcovado" and "Punta Banco" were less used by fishermen (9.9% of trips). In the captures, 345 (39.6%) were sharks (Sphyrnidae Carcharhinidae, Heterodontidae, Ginglymostomatidae and Triakidae), 228 (26.1%) bait fish (Aridae), 112 (13.1%) rays (Dasyatidae, Myliobatidae, Rhinobatidae and Mobulidae) and 111 (12.7%) commercial fish (Lutjanidae, Serranidae, Sciaenidae). The most abundant ray was D. longa, with 75.7% of total rays caught, n=112), and more than 10% of total catch. The longtail stingrays male: female ratio was 1.33:1. Mean width disc length was 84.63±12.11cm. The highest Catch per unit effort, CPUE, was in January-February (0.006 stingrays per hook per hour). The lowest was in July and August (0.0004). Nearly all rays caught were released. We recommend regulations on the artisanal bottom line during from January to February in the areas of Los Bajos, Pique Fijo, and La Cienega. Rev. Biol.

The use of fish in Ilhabela (São Paulo/Brazil): preferences, food taboos and medicinal indications / O uso de peixes em Ilhabela (São Paulo, Brasil): preferências, tabus alimentares e indicações medicinais

This study was conducted in three communities of artisanal fishermen from Ilhabela, located on the northern coast of São Paulo, Brazil. The objective was to analyze the preferences, taboos and medicinal indications of fish and thus representing one of the interactions of fishermen with fish stocks. Data collection was conducted through interviews with the aid of semi-structured questionnaires. We interviewed 25 families, 29 residents in three communities studied during our fieldwork for data collection. Five interviews were done in Jabaquara Beach, 6 in Fome Beach and 14 Serraria Beach. During the interviews, 18 species were cited as preferred for consumption, 11 species considered to be taboo (food prohibited), 5 species were cited as avoided as food, and 4 species indicated in case of illness. The families of fishermen prefer to consume finfish and do not consume puffer fish, the latter probably due to its toxic characteristic. Fish such as little tunny, largehead hairtail, shark, serra mackerel and king mackerel are avoided by unhealthy people and in cases of wounds, inflammation, pregnancy and postpartum. Other fish, such as sea chubs, silver porgy, bluefish and grouper are reported as medicinal in these situations. Aspects related to fish consumption are part of the knowledge of fishermen and their families and provide a wealth of information that combined to biological information is useful for the conservation of fishery resources. Data such as those presented in this study, regarding the use of aquatic animals for treatment of diseases, could serve as a basis for future studies on substances that contain active elements in curing diseases.

Este trabalho foi realizado em três comunidades de pescadores artesanais de Ilhabela, localizadas no litoral norte do Estado de São Paulo, Brasil. O objetivo foi analisar as preferências, os tabus e as indicações medicinais dos peixes e, desta forma, representar as interações dos pescadores com os recursos pesqueiros, visando entender os aspectos biológicos e culturais envolvidos. A coleta dos dados foi realizada através de entrevistas com o auxílio de questionários semi-estruturados. Foram entrevistadas 25 famílias, das 29 residentes nas três comunidades estudadas durante a coleta de dados, sendo que 5 delas foram realizadas na Praia do Jabaquara, 6 na Praia da Fome e 14 na Praia da Serraria. Foram citadas 18 consideradas preferidas para o consumo, 11 espécies consideradas como tabus, 5 espécies evitadas e 4 indicadas no caso de doenças. As famílias de pescadores preferem consumir peixes de escama e não consomem o baiacu, este último provavelmente devido a sua característica tóxica. Peixes como bonito, espada, cação, sororoca e cavala são evitados em casos como feridas, inflamações, gravidez e pós parto e outros como pirajica, marimba, anchova e garoupa são indicados como peixes medicinais nestas situações. Aspectos relativos ao consumo de pescado fazem parte do corpo de conhecimento dos pescadores e suas famílias e constituem um acervo rico de informações que somadas as informações biológicas são úteis para a conservação dos recursos pesqueiros. Dados como os apresentados nesse estudo, com relação ao uso de animais aquáticos para tratamento de doenças, podem servir de base para estudos futuros sobre substâncias que contenham elementos ativos na cura de doenças.
