Genetic Evaluation of GIFT and Existing Strains of Nile Tilapia, Oreochromis niloticus L., Under On-Station and On-Farm Conditions in Bangladesh

Abstract

Comparative production performances of Genetically Improved Farmed Tilapia (GIFT) and existing Nile, Oreochromis niloticus L. strains were assessed in five test environments (nursery systems, cisterns, hapas, net cages, and grow-out ponds) and six multi-locational sites (Trishal, Chandina, Manikganj, Paikgacha, Jessore Sadar, and Mithapukur) under on-station and on-farm conditions in Bangladesh. The mean weight gains at harvest of the GIFT strain was significantly higher (40-57%) than the existing Nile tilapia strain in all the trials.
