Abstract

This research was conducted in Desember – January 2021 at the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Sciences, Universitas Riau. This study aims to determine the effect of feeding and the number of different feeds on the growth and survival of Nilem (Osteochillus hasselti) larvae. The method used was a completely randomized factorial design with 9 treatments and 3 replications. F2P25 (Feed Frequency 2 x daily + Total Feed 25% of body weight), F4P25 (Feed Frequency 4 x daily + Total Feed 25% of body weight), F6P25 (Feed Frequency 6 x daily + Total Feed 25% of body weight), F2P50 (Feed Frequency 2 x daily + Total Feed 50% of body weight), F4P50 (Feed Frequency 4 x daily + Total Feed 50% of body weight), F6P50 (Feed Frequency 6 x daily + Total Feed 50% of body weight), F2P75 (Feed Frequency 2 x daily + Total Feed 75% of body weight), F4P75 (Feed Frequency 4 x daily + Total Feed 75% of body weight), F6P75 (Feed Frequency 6 x daily + Total Feed 75% of body weight ). The results showed that different feeds and feeds had a very significant effect on growth with absolute length (3.14 cm), absolute weight (2.70 g), specific growth rate (14.56), and survival rate (87, 77%).

Abstract

Natural feed is an initial feed that has a complete nutritional content and is closer to the biological needs of fish larvae, one of which is Tubifex sp. Tubifex sp is a type of natural feed that is very important in freshwater aquaculture activities, especially for catfish hatcheries. Tubifex sp. has a fairly high nutritional content, 57% protein, 13.3% fat, 2.04% crude fiber, 3.6% ash content and 87.7% water. The purpose of this study was to determine the effect of fermentor dosing on tofu dregs as a Tubifex sp. culture medium on population and biomass growth rates. This research was conducted in August - October 2023 located in the laboratory of the Faculty of Fisheries and Marine, Riau University. The research method used was an experimental method using a completely randomized design (CRD), consisting of 4 treatments and 3 replications. The fermentor dose used was in the treatment P0 (0.0 ml), P1 (0.5 ml), P2 (1.0 ml), P3 (1.5 ml). The results of this study indicated that the dose of fermentor on tofu dregs as a culture medium for Tubifex sp. had a significant effect (P<0.05) on population and biomass. The highest population and biomass were found in treatment P2, with a population of 13519 ind and a biomass of 49.52 grams which were reared for 56 days. Based on the results of the study it can be concluded that giving fermenter doses to tofu dregs as a Tubifex sp. culture medium can increase population and biomass.

Abstract

This research was conducted on April - May 2021, at Fish Hatchery and Breeding Laboratory of Fishery and Marine Science Faculty of Riau University. The aim of this research was to determine the effect of Kirinyuh leaf (Euphatorium odoratum) solvent and the optimal dose on hatching rate of tambaqui larvae (Colossoma macropomum). The method used was a Completely Randomized Design Factorial with 4 treatments and 3 replications. The dose of kirinyuh leaf solvent used was P0 (0 mg/L) P1 (100 mg/L) P2 (120 mg/L) and P3 (140 mg/L). rGH with 3 levels; 0 mg/L (D0), 1.5 mg/L (D1,5) and 2.5 mg/L (D2,5). The immersion duration of kirinyuh leaf solvent is 20 minutes with 100 eggs for the density. The results showed that the use of different doses of kirinyuh leaf solvent gave very real effect to fertilization rate with highiest point (87,33%) following with hatching rate (88,00%), and survival rate (83,66%).
