The present study was conducted to determine the effects of squid oil on endangered butter catfish, Ompok pabda confer enhanced breeding with embryonic and larval development for promoting its aquaculture. A total 360 fish were obtained from Brahmaputra River, Mymensingh, Bangladesh, which, 60 stocked in each tank having an initial weight length 16.35 ± 0.57 g 15.25 0.38 cm, respectively, cisterns 1.22 × 2.44 1.25 m (total 6 cisterns) maintained at 90 cm water depth. During experimental period, a constant physico-chemical conditions such as temperature, pH, dissolved oxygen (DO) 26.5 2 °C, 7.4 0.2, 6.7 0.5 ppm, cistern. As source eicosapentaenoic acid (EPA) docosahexaenoic (DHA), dietary 1 % (SQO) supplemented diet treated group (SQO diet) compare while control offered basal without SQO supplementation (CON diet). fecundity, spawning, fertilization, hatching rate, survival rate fry significantly (P < 0.01) higher than CON group. Moreover, better early observed i.e. size fertilized egg diameter, growth developmental stages larvae but not different Collectively, results showed that improved reproductive performances catfish. findings this could assist develop nutrient-rich broodstock catfish farm level which may ultimately reduce mortality poor offspring commercially important species.
