Abstract

The study was conducted to evaluate the best effect of Human ChorionicGonadotropin Hormon (hCG) doses (800, 1000, and 1200 IU/Kg body weight offemale on breeding performance of selais fish (O. hypopthalmus) under alaboratory condition. The breeding performance was judged on the base of thetotal weight of stripped eggs, fertilization rate, hatching and survival of 6 days oldfry were considered.The results indicated that the total weight of stripped eggs were the highestwhen females were injected with 1200 IU/Kg body weight (45 eggs/g of female)compared to those injected with 1000 IU/Kg and 800 IU/Kg of body weight.Percentages of total fertilized eggs and hatching were 41,58% and 31,94%respectively, which were the highest among treatments. The highest net survivalof 6 days old fry was found to be 97,24% at 800 IU/ Kg weight of female.

Abstract

The research was conducted for 60 days from April to June 2017. The aim of this research was to know the utilization of fermented leucaena leaves meal as a substitution of soybean meal in the diets on the growth and feed efficiency of Thai Catfish. Completely randomized design (CRD) was used in this experiment, with one factor, five level treatment and three replications. Fish were reared in 1 m3cages with stocking density 20/cages. Feeding trial were replacing soybean meal with fermented leucaena leaves meal applied to P1 (0%), P2 (25%), P3 (50%), P4 (75%), and P5 (100%). The fish used in this research with 2,13 ± 0,39g of weight. The result of this research showed that fermented leucaena leaves meal has significant effect (P>0,05) on growth and feed efficiency of Thai Catfish. Diets which contains 75% of fermented leucaena leaves meal and 25% of soybean meal (P4) produce the highest specific growth rate (4,11%/day), feed efficiency (62,6%), feed digestibility (59,45%), and protein retention (18,85%). Based on the result of this study conclude that fermented leucaena leaves meal can be used as substitution for soybean meal in diets of Thai Catfish.

Abstract

A study was conducted to induced triploidy in fertilized egg of sheatfishlarvae , (Kryptopterus lympok) using heat shock. The eggs were exposed at 40OCfor shock duration of 1 , 3 , 5 and 0 minutes as a diploid control. Results showedthat the 5 minutes shock duration was the highest triploid induction and yield(91.7 and 62.9%). Erythrocyte analysis showed that the volume of triploid fishgroup was bigger that that of diploid one. The fertilization, hatching and survivalrate was lower in triploid groups, while SGR was higher compared to diploid fish.
