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.

Abstract

The production of good quality seed for culture purpose begins with proper attention to the nutritional requirements of the parental broodstock. The objective of this research was to know the level of lipid in broodstock feed to reach good seed production.The experiment was conducted in concrete ponds located at Research Instalation for Aquaculture Environment and Toxicology,Cibalagung, Bogor. Broodstock with average individual body weight of 420.8 ± 72.10 g were cultured in concrete pond 3.5 x 2.53x 0.8 m with stocking density of 15 fish/pond. Pelleted fish with 35% protein content and different lipid level of 4, 6, 8, 10, and 12 % were given with daily ratio 2 % of body weight. Gonadosomatic index, ovosomatic index; the weight, the number and the diameter of egg; fertilization rate, hatching rate, percentage of larva produced and daily growth rate and survival rate of 21 days old seed were observed. The result showed that there were no significant difference (P>0.05) among treatments for all parameters except for the diameter of the egg. The result showed that all of the broodstock were matured in three months.Gonadosomatic index were ranged between 13.69-16.65%, ovosomatic index: 11.26-14.62%. The weight of the egg varied from 1.45-1.69 mg/egg with the diameter in between 1.37-1.66 mm. The number of eggs per kg broodstock varied from 74,473-88,787 with fertilization rate of : 67.15-93.29%, and hatching rate were ranged from 88.33%-96.62%. The feed with 8% lipid level showed the highest value of gonadosomatic index (16.65%), fertilization rate (93.29%), percentage of larva produced (90.14%), egg weight (1.69 mg) and egg diameter (1.66 mm). Average daily growth rate of the 21 days old offsprings was 18.12%-19.25% with survival rate of 60.25%-75.50%. The feed with 8% lipid level tends to give the best effect on the reproduction parameters and the performances of the seed.

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 experiment was conducted to evaluate the growth of Pangasius djambal which were fed with different dietary protein levels.Fifteen fingerlings averaging 6.13 g individual body weight were stocked in each of 9 fibreglass tanks filled with 30 liters of water.They were fed daily for 42 days with diets containing 30%, 35% and 40 % protein. The feed was given in crumbled form at 7% of total biomass,4 times a day and contains 2600 k.cal.DE/kg feed.The result showed that feeds with different protein content gave qudratic respon curve. Maximum values for protein retention (36.65%) were obtained with feed containing 34.14 % protein.The feed with 35% protein content gave the lowest (78.12%) lipid retention. Feed conversion ratio (1.31-1.36), daily growth rate(3.64-3.82%) and protein efficiency ratio (2.05 - 2.29) were not different among treatments.The survival rates 100% were the same for all treatments.It is suggested that feed with protein content 35% and 2600 K. cal DE/ kg feed can be used in intensive culture of Pangasius djambal fingerlings to attain the best growth and suvival rate.
