Abstract
Barbodes schwanenfeldii is an opportunist fish that are able to feed mainly on spilled pellets from the floating net aquaculture and this they may be reared in the 2nd layer of floating net cage (the outer layer net). To understand the ability of the outer net reared fish to use the spilled pellets for supporting their life and to reproduce, a study on the morphoanatomy of the fish has been conducted on August to September 2021. The B. schwanenfeldii in the outer net were not given any food and they eat only on the spilled pellets. The cultured fish (Cyprinus carpio) as well as B. schwanenfeldii were reared for 6 months and the cultured fish was fed with commercial fish feed pellets. The inner cage size was 4 x 4 x 4 m, while the outer net was 5 x 5 x 6 m. In layer 1 cages density of Cyprinus carpio seed with 3cm body length and weught 3gr. Stocking density of 500 fish/cages. Where as in layer 2 cages, B.schwanenfeldi in outer net are kept which are caught from the reservoir so that the body size of the fish varies. The stocking density of B.schwanenfeldi in layer 2 cages was 30 fish/cages. Fish sampling was carried out once, in the 6th month, just before the carp in the 1st layer cage was harvested. Parameters measured were body length, body weight, maturity level, Viscera Somatic Index (VSI), Gonado Somatic Index (GSI) and Hepato Somatic Index (HSI). In this study, the sample fish in the outer net was bigger than that of the free living fish, they were 17.5- 24.5 cm TL, with 74 - 231g BW and they were in the 3rd, 4th and 5th maturity stages with 140% GSI, 70% VSI and 4.50% HSI. While the free living fish were smaller, they were 11.9- 21.5 cm TL, with 24 - 154g BW, they were in the 2nd, 3rd and 4th maturity stages, with 40% GSI, 10% VSI and 1% HSI. Data obtained indicated that B. schwanenfeldii are able to use the spilled pellets to support their live and to reproduce.
Keywords: Outer floating net, opportunist fish, hepatosomatic index, viscerasomatic index, gonadosomatic index.
