GROWTH PERFORMANCE OF ASIAN CATFISH (Pangasius djambal) REARED IN AQUARIUM WITH DIFFERENT SALINITY

Abstract

Asian catfish (Pangasius djambal) of the family Pangasiidae are potential fish species for being farmed and have great economics importance. Thus, many efforts of breeding practices have been done to increase
their production. In most species larvae growth are dependent on salinity. Therefore, it is really important to provide optimum level of salinity on Pangasius djambal larvae rearing. The aim of this experiment was to
know effect of different salinity on growth performance of Asian catfish. Water salinity used as treatment was: (A) 1‰; (B) 2‰; (C) 3‰; and (D) 0‰ (as control) with three replicates, respectively. Larvae were reared in 9 aquaria by dimension 95 cm x 45 cm x 45 cm filled with 100 liters of water. Sampling were taken every 7 days and the experiment was conducted for 35 days. The total body length, spesific growth rate, and daily growth rate were directly measured during the experiment. The results showed that the highest growth of
total body length were obtained in treatment B (43.67±0.58 mm), followed A (41.67±2.89 mm), D (41.67±10.41 mm), and C (38.67±3.06 mm). Optimum total body length was obtained in 2‰ salinity level but no significant difference (P>0.05) in specific growth rate and daily growth rate for all treatments
