dc.description.abstractA study was conducted in Babati and Burunge lakes in Tanzania to assess the limnological characteristics and fishery resources from August 2022 to March 2023. Sampling was conducted from ten different stations in each lake using standard method ISO 5667-4:1987. 200 fishes representing ten different species were sampled at fishermen landing sites and measured. The results showed no significant difference (p>0.05) in limnological characteristics within seasons and between lakes. Limnological characteristics were within WHO agreed values except biological oxygen demand (10.7 ± 6.43 mg/l), Chloride (31.33 ± 0.88 mg/l), pH (9.8 ± 0.06) and turbidity (51.3 ± 0.88 cm) which were all higher than the accepted values. Chlorophyll-a contents were lower than recommended standard for both lakes in both seasons. Ten fish species were found, six found exclusively in Lake Babati and four in Lake Burunge. Oreochromis niloticus, Oreochromis urolepis and Oreochromis variabilis were restricted to dry season in Lake Babati, while the rest were found in dry and wet seasons in both lakes. Majority of fish species sampled had larger size in the dry than in the wet season. Most fish species sizes were within the reported size ranges for that particular fish species. Clarias gariepinus recorded maximum size (872.3 ± 15.38 g and 54.2 ± 1.96 cm) in Lake Babati, while Tilapia melanopleura recorded maximum size (443.3 ± 6.17 g and 25.7 ± 0.33 cm) in Lake Burunge. The study concluded that both lakes water met the requirements for fish production and requires effective management against pollution.
