Fisheries in Lake Tinishu Abaya (Ethiopia) could be managed using dietary nature of Nile tilapia (Oreochromis niloticus L. 1757)

Lake Tinisu Abaya is home to some fish species. The lake’s native species include Barbus and Tilapia zilli. (Oreochromis niloticus L.) were stocked in Tinishu Aabaya 1997. This study aimed investigate the feeding behaviors of O. develop an appropriate fisheries management approach lake. 428 samples (2.5 30.9 cm 1.1 475 g) collected calculate diet composition. Out total gut contents examined, 55 (12.85%) found be empty 373 (87.15%) containing one or more food items. behavior lake revealed that phytoplankton (39.5% by volume) macrophytes (25.81% most noteworthy items followed detritus (14.39%) zooplankton (12.95%). With increasing size, importance phytoplankton, macrophytes, increased while contribution zooplankton, insects, other foods with animal origin decreased. Seasonal variation composition was evident (t-test; p < 0.05). Macrophytes, dominating during wet season, predominated dry season. demonstrated had phytoplanktivores primarily consumed seasons size a significant impact on their preferences. comprised both plant origins. It concludes dietary habit is, generally, omnivorous type.
