Abstract
This study investigated the efficacy of a specially formulated fish feed incorporating Clerodendrum colebrookianum leaves and dehydrated Black Soldier Fly (BSF) larvae in promoting the growth of Chocolate Mahseer (Neolissochilus hexagonolepis). A total of sixty fingerlings were equally allocated into control and experimental groups and were maintained over a period of 90 days. The control group received a traditional feed comprised of rice bran and mustard oil cake, whereas the treatment group was given a diet supplemented with BSF larvae and C. colebrookianum, along with the same base components. The dietary formulation was calibrated utilizing the Pearson Square method to achieve a crude protein level of 35%. Fish that were provided the enhanced diet exhibited significantly improved results regarding body weight increase (49g –55 g), growth efficiency (SGR: 1.12–1.20), and feed conversion ratio (FCR: 1.37–1.54). Both groups exhibited complete survival throughout the duration of the experiment. These results endorse the incorporation of local plant and insect protein sources as viable and sustainable feed constituents aimed at enhancing aquaculture productivity for Chocolate Mahseer.
