ABSTRACT
The effects of water pH on life history parameters of Bosmina tripurae have been studied to determine the most suitable water pH desired for the maximum growth and development of this newly discovered cladoceran species. The study was carried out under the laboratory condition at 20 ± 2°C. Five pH ranges 5.0 ± 0.2, 6.0 ± 0.2, 7.0 ± 0.2, 8.0 ± 0.2 and 9.0 ± 0.2 with six replicates for each pH consisting of one animal in each Petri dish (80 × 15 mm) were used for the study. 20 mL of respective test medium was maintained with Chlorella sp. (2 × 104 ± 0.03 cells mL-1) in each Petri dish throughout the experiment. Thirty (30) animals were observed daily to investigate different life history parameters like total life span, age at maturity, number of eggs, neonates and egg batches etc. at different condition. From the study it was found that acidic water (pH 5 ± 0.2) is more suitable for the culture of Bosmina tripurae in laboratory condition.
