Abstract
Amazon sailfin catfish, Pterygoplichthys pardalis is an invasive fish that has affected native fish in several inland waters in Indonesia. This fish is not widely consumed, and its utilization is still very limited, so the population is increasing as well. One effort to utilize it is to process it into fish meal and then as a source of animal protein. The aim of this study was to analyze the use of P. pardalis meal as a substitute for the commercial fish meal on growth performance and feed utilization in tilapia, Oreochromis niloticus and carp, Cyprinus carpio aquaculture. Tilapia and carp, respectively, had total lengths of 4.5 cm and 5.5 cm and body weights of 3.2 g and 2.9 g. The treatments consisted of five, namely diet of P. pardalis meal and commercial fish meal, namely treatment A 0 and 100 %, B 25 and 75 %, C 50 and 50 %, D 75 and 25 % and E 100 and 0 % were maintained for 60 days. The results showed that the treatment of the five diets had a significant effect on body weight gain, daily growth rate, specific growth rate, feed conversion, feed efficiency, and protein efficiency ratio of tilapia and carp. The commersial meal diet was 100 % higher but not different from the P. pardalis meal 25 and 50 % diets. P. pardalis meal can be used as a raw material for artificial feed to replace commercial fish meal up to 50 %, but its use of up to 100 % does not affect the survival rate of tilapia and carp.
