Abstract

This research was conducted from September to October 2008 in FishSeeding and Hatchery Laboratory Faculty of Fisheries and Marine Science,University of Riau. The aim of the research was to know the effect of the severalcombination feed on the growth and survival rate of Ompok hypophthalmuslarvae.A complete random design was applied with five treatments and threereplications : no combination (Artemia sp), combination Artemia sp and prawnpellet, Artemia sp and egg yolk, Artemia sp and tubifex sp, Artemia sp, egg yolk,Tubifex sp and prawn pellet. The result showed that the best treatment was feedingwith combination Artemia sp and Tubifex sp, larvae produced were 1,329 gr/ 30day, 60,5 mm/30 day and survival rate 75%. The water quality conditions were :water temperature 280 C, pH 5-6, dissolved oxygen 3,9- 5.6 mg/l.

Abstract

This research was conducted 5 to 20 February 2008 at Fish BreedingLaboratory Fisheries and Marine Science Faculty of Riau University. It was aimto know the influence of hormone ovaprim to ovulation and fertilized includepercentages of hatcing and survival rate of larva ”tambakan” (Helostomatemmincki C.V). It the research experiment method was applied with fourtreatments and tree replications. The treatment injection by fisiologis solution0,65 %, injection by ovaprim 0,3 ml/kg, 0,5 ml/kg and 0,7 ml/kg weigh of fish.The result showed that the injection by ovaprim indicated different parameters infew treatment. The best result was got from 0,7 ml/kg doze with latent time 5hours, total of eggs ovulated 30.072 eggs, diameter 0,38 mm and 17 % eggripeness. But this doze did not give effect for the percentage of fertilization,percentage of hatching and survival rate of larva tambakan (Helostoma temmincki C.V).

Abstract

A study aims to find out the domestication and triggering gonadal maturation techniques of Thynnicthys thynnoides obtained from Kampar River, Riau has beenconducted from June to August 2009. Fish samples were kept in 1 x 1 x 1 m cages,30 fishes/ cage. Fishes were fed on three types of food namely dried Tubifex, shrimppellet (without vitamin E addition) and shrimp pellet that is enriched with vitamin E(100 gram/ kg ). The food provided was 5% of total fish body weight/ day.Result shown that fish domestication can be conducted by keeping them in the cagesthat are placed in the area where the fish are captured. During the first week, fisheswere not fed and in the following weeks they were provided with the treated fed. Thebest result obtained in the fishes that are feed with shrimp pellet that is enrichedwith vitamin E. During the research period (8 weeks), 12 fishes were sampled and 5of them were in the 4th gonadal maturity level, their maturity indices was 15.603%,fecundity 19,516 eggs, egg diameter 1.07 mm and semen volume produced 0.945 ml.Key words : domestication, maturity indeces, fecundity egg diameter
