Abstract

This study aims to compare the growth performance of common carp (Cyprinus carpio) reared in floating net cages (FNC) in Cirata Reservoir, West Java, with different commercial feeds. This study utilized four different commercial feeds, namely: commercial feed A (protein content: 28.10%), treatment B (protein content: 28.80%), treatment C (protein content: 28.90%), and treatment D (protein content: 29.12%). The average weight of the fish used at the beginning of stocking was 23 g. The FNC plot used was 3 × 3 × 3 m in size. The frequency of feeding was three times a day (08:00, 12:00, 17:00) with feeding at satiation for 100 days of rearing period. The results showed that treatment D (29.12%) provided the best final biomass performance, as well as the highest average weight, specific growth rate, and feed cost per gain and feed conversion value, compared to the other three treatments. Based on the research results obtained, it can be concluded that the highest growth performance was achieved in commercial feed treatment D, which had a protein content of 29.12%.
