Abstract

Striped snakehead is one of the potential local species, however, its production in Indonesia still comes from capture fisheries. Over exploitation had decrease the population in nature. Domestication is one of promising tool to solve the problems faced. In order to breed the domesticated species, the information of their reproduction was needed. This study aimed to describe relationship between length and weight, length and fecundity, weight – fecundity and gonad weight – fecundity of the striped snakehead from West Java. A total of 19 mature female specimens were collected from Parung (Bogor), and seven mature female specimens were collected from Babelan (Bekasi). The results showed that the determinant value (R2), the first for Parung and the second for Babelan, between weight and fecundity were 0.599 and 0.843, length-fecundity were 0.541 and 0.841; gonad weight – fecundity 1.00 and 0.846 Gonadosomatic Index (GSI) ranged from 0.67 to 9.94% and 2.03 to 8.17%. Gonad Index ranged from 6.17 – 76.73 and 18.48 – 76.77, respectively. The data indicated that growth pattern was allometric. Length and body weight has linear relationship with gonads and fecundity. Fecundity has higher correlation to the weight rather than length. Gonad weight and fecundity has a strong relationship.

Abstract

The aim of this research was to determine the optimum percentage of glycerol addition into the diets of  Nile Tilapia (Oreochromis niloticus) on growth performance, feed convertion ratio, and survival rate. The research was conducted using 15 aquaria with the size of 60 x 50 x 45 cm3, each containing 25 O. niloticus with average initial weight of 4.63 ± 0.15 g. The experiment was conducted using a complete random design with five treatments and three replications. Isonitrogenous (31%) and isocaloric (17 MJ.kg-1) diets were provided for 60 days of rearing period. Five diets were formulated with glycerol content of 0% (G0); 5% (G5); 10% (G10); 15% (G15), and 20% (G20). Fish were fed twice daily with experimental diet at satiation level. The result showed that addition of 10% glycerol in the diet (G10) presented the highest values for weight gain (105.85 ± 0.40%), specific growth rate (3.44 ± 0.01%), protein retention (27.75 ± 0.02%), protein efficiency ratio (2.53 ± 0.15%), lipid retention (60.44 ± 0.03%), and feed convertion ratio (1.59 ± 0.01%) (P < 0.05). Survival rate was not affected by dietary containing glycerol (P > 0.05). Therefore, addition of 10% glycerol into the diet gave a significant increase on growth performance and feed convertion ratio without adverse effect on survival rate of Nile Tilapia.

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.
