A Study of Growth Performance of African Catfish, Clarias Gariepinus in Hapa System

Hapa is a rectangular or square shape like cage placed in earthen pond is a type of a culture system that used for holding fish various reasons. It is rarely practice in fish
farming compare to other culture system. Hapa system usually use for hatchery phase of the fish before transfer it into pond or other system for the grow out until achieve marketable size. Objective of present study is determined the viability of using hapa in African catfish farming. In the present study, African catfish (Clarias gariepinus) fingerling with initial body weight of 8.05 g ± 0.08 and the size was 5 cm were used to know the growth performance of African catfish where 2 000 fingerlings were stocked in
the hapa system. The growth performance of the experimental fish was evaluated for eight weeks. The final body weight of catfish on week eight was 7.31 g ± 0.33. The best value
of feed conversion ratio (FCR) was 2.64 ± 0.81 on week two which the least value compared to other weeks. For specific growth rate (SGR) the highest value was 0.26 ± 0.06 which on week two. The water quality including temperature and pH in hapa were within acceptable range except the dissolved oxygen. The finding of the present study was needed for further research by husbandry students to make it worth, thus it can be evidance for the farmers to use it in fish farming.
