Abstract

Green catfish is a commodity that is not only potential to be cultivated in the pond and in the floating net cages, but also easy to adjust to the artificial feed. The objective of this research is to evaluate the effect of different feed types (sinking and floating)on the growth performance of green catfish(Hemibagrus nemurus.One thousand and six hundred fingerlings averaging 2.50 g of 3 individual body weight were stocked in each of earthern ponds (10 x 8 x 1.2 m ). They were fed daily for four months with the same protein content (31%) and lipid (6%) diets. The feed was given in pelleted form at 8-4% of the total body weight. The result of this study showed that no significant difference (P>0.05) between different feed types. The sinking feed gave specific growth rate (2.35%), feed conversion ratio (2.49), protein retention (18.92%) and protein efficiency ratio 1.13 while the floating type gave the values 2.49%, 2.37, 20.48% and 1.21, respectively. Lipid retention of sinking feed (34.84%) is lower than that of floating type(48.39%).The survival rates ranged between 76.56-84.54%.Feed type sinking with protein content of 31% can be used in the rearing of fish in earthern pond.

Abstract

The feeding rate and the feeding frequency influencing the growth and survival rate of fish. The objective of this research was to know the proper level of feeding frequency for supporting the growth of patin pasupati (hybride between Pangasius hyphophthalmus and P. djambal).The experiment was conducted in fibre glass tanks located at Research Instalation for Genetic and Freshwater Aquaculture Technology, Sukamandi. Patin pasupati fingerling with average body weight of 2.23 ± 0.48 g were stocked in 9 fibre glass tanks, each filled with 30 litres of water.The experimental design was Completely Randomized Design with 3 treatments and 3 replications. The treatments were feeding frequency as follows 1, 3 and 5 times per day. The feeding rate was 8% of total body weight per day.The parameters were specific growth rate, average body weight gain, feed conversion ratio, protein retention,lipid retention, protein efficiency ratio and survival rate. The results of experiment indicated that there were significant different(P<0.05) among treatments for specific growth rate, individual body weight gain, feed convertion ratio,protein retention, lipid retention and protein efficiency ratio.The highest value for specific growth rate (7.03%) and protein retention (54.59%) were found for feeding frequency 5 times per day.The values of feed conversion ratio and survival rate for feeding frequency 5 times per day were 0.83 and 100%, respectively.
