Abstract

ABSTRACT The effect of three protein levels of commercial diet on the growth performance, gonad maturation and fecundity of first maturity of Indonesian leaffish (Pritolepis grooti) was conducted in 54 liters recirculation aquaria system for 10 months rearing period. Eight-week-old artificial spawned  Indonesian  leaffish katung (Pristolepis grooti Bleeker)) fry with an average weight (SD) of 0.560(0.116) g were fed  5% BW three times a day with commercial diets 18, 28 and 38% Protein.  Fish fed on 38%  protein diet showed better growth and feed conversion ratio than those fed on 28 and 18% diets. Males matured earlier than females: the firstmature males were recorded when they were 5 months old, whereas the females matured after 6 month rearing period. The mean percentage of mature female fish rose with increasing feed protein level. It was also found that the percentage of mature fish rose with the increasing fish age and size. More than 70% males matured at the age of 6 months in all diet. After 10 months rearing period, the percentage of matured female fed on 38% protein was 100% while those fed on 16% protein was 25%. Smallest size at spawning of males and females was 8.5 cm (23 g) and 13 cm (65 g), respectively, and dietary protein levels influenced the size of fish at first maturity. It was found that  the protein level significantly effected the gonado somatic index (GSI). Fecundity increased with increasing dietary protein level. The relative fecundity (eggs /g or cm female) was higher at the higher  dietary protein level.   Keywords : Dietary Protein; Growth; Gonad Maturation; Fecundity; Indonesian leaffish Pristolepis grooti

Abstract

The research on the Comparisson between natural spawning and artificial spawning in gold fish oranda (Carassius auratus) was conducted in February 2014 in the Fish Hatchery and Breeding Laboratory of the Faculty of Fisheries and Marine Sciences, University of Riau. The research was to compare the result between natural spawning and artificial substrate with result artificial spawning using injection with ovaprim 0,5 ml/kg body weight females; 0,2 ml/kg body weight males in gold fish oranda (Carassius auratus). The container used in this study was 6 unit fiber size 100x60x50 cm2 The method used is an experimental method or direct observation and than process spawning one unit sampel don’t in simultaneously because different maturity level gold fish oranda.The results treatment showed that is natural spawning better than artificial spawning in terms of index ovisomatic 12,2 % (IOS); fertilized rate 86,8 % (FR), hatching rate 91,1 % (HR), survival rate of 10 days old fry 97,9 % (SR).Keywords: Spawning, substrat, gold fish oranda (Carassius auratus)

Abstract

This research was conducted from February-June 2014 in Hatchery and Breeding Laboratory, Faculty of Fisheries and Marine Sciences, University of Riau. The objective of this research was to evaluate the intergeneric hybridization between gold fish (Carassius auratus auratus) with silver sherkminow fish (Osteochillus hasselti) by comparing the fertilization rate, hatching rate, survival rate in four days (SR-4), survival rate for 30 days (SR-30), extra weight and value heterosis ( hybrid vigor ) between fish larvae results hybridization with fish control. The method is applicable in the experimental methods, where spawning artificial was conducted by the use of eggs and fish sperm of a comet (Carassius auratus auratus) and fish nilem (Osteochillus hasselti) that has been injected using ovaprim with a dose of 0,5ml / kg.The highest percentage of fertilization is marriage ♂ K x ♀ K (75.04%), follow by ♀ K x ♂ N (70.87%), ♀ N x ♂ N (31.3%) ♀ N x ♂ K 30.14%. Persenatage the highest hatching is a control that is ♂ K x ♀ K (91.50%), which followed ♀ N x ♂ K (88.37%), ♀ N x ♂ N (87.44%) and ♀ K x ♂ N (68.67%). The highest percentage of survival rate 30 days in sequence is ♀ K x ♂ K (69.08%), ♀ N x ♂ N (60.17%) and ♀ K x ♂ N (2.06%). As for hybrid ♀ N x ♂ K died at the age of 4 and 5 days. The highest weight added sequentially is the larvae of spawning results ♀ K x ♂ N (0,23 g), ♀ K x ♂ K (0,21 g) dan ♀ N x ♂ N (0,19 g). All values of heterosis is negative except at the FR (33.29 %) and extra weight (15.25 %) from ♀ K x ♂ N.Key words : hibrydization, gold fish, nilem

Abstract

The research on rearing of green catfish larvae (Hemibagrus nemurus) with different protein source of paste feed was carried out for 40 days in the Laboratory of Fish Hatchery and Breeding Faculty of Fisheries and Marine Sciences University of Riau. The aim of this study was to evaluate the substitution of tubifex worm with different protein sources of paste feed. Protein sources used were squid meal, fish meal, cockle meal and mysid meal. The effect on growth and survival was determined.Result showed that tubifex worm cauld not be substituted by the paste feed in rearing green catfish larvae for 40 days rearing period. Among the paste feed, the squid meal protein source paste feed was the best and more efficient in term of highest survival rate and the lowest cost per fish.Keywords: paste feed, growth, survival Hemibagrus nemurus larva

Abstract

This research was conducted for five months from 20 May – 20 October 2013, releasing % of brood fish was done in the soil pond and ovulation was carried out in the Hatchery Laboratory and fish breeding, University of Riau. The purpose of this study was to evaluate the best dose of vitamin E added to fish pellets for egg quality of kelabau fish (Osteochilus kelabau). Applied doses of Vitamin E were 0, 100, 150, 200 mg/kg pellets. Parameters measured were the duration for gonadal maturation achievement, ovi somatic index, latency time, number of eggs ovulated, egg diameter at the end of experiment. The results showed that the maturation % gonad took place in 3 month in brood fish feed wisth vitamin E 200 mg/kg pellet. Which was shorter than that with out added with vitamin E. Latency time was 13.5 hours and the average number of ovulated eggs were 4. 807. The ovi somatic index was 0.82 % and the average diameter of eggs after treatments was 1,4 mm. Whereas the control treatment without giving Vitamin E mature gonads during maintenance 5 months in rainfed pond. water quality obtained during the study available temperature about 26 – 37 0C, pH 5 – 6, Dissolved Oxygen 1,42 – 2,20 ppm, water level 32 – 37 cm and ammonia 0,18 – 0,30 ppm.Key words: Vitamin E, Eggs quality, Osteochilus kelabau.

Abstract

Productivity of Cryptopterus spp (Selais Janggut fish) in Kuantan Singingidistrict has decreased each years. This indicates that Cryptopterus spp extinctconditions and should be a priority for recovery and restocking this fish to freshwater of Kuantan Singingi district. To recovery this fish can be done byaquaculture in cages method and restocking this fish in to freshwater byconsidering the type and environmental conditions in each type of public watersKuantan Singingi. Policy strategy in the management of fish stocks was tomanage of fishing area and by management of the conservation area of fresh waterand development of cage aquaculture program in fresh waters .Keywords: Cryptopterus spp, fish stocking, fresh water

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.
