Abstract

This research was conducted on May 2015 in Kampar river waters, BuluhCina village, Siak Hulu District, Kampar Regency, Riau Province. The purpose ofthis study was to determine the webbing is effective for catching fish (Rasbora sp)using gill nets. The data collected in this study include the type of fish, the amountof fish caught in weight (grams), individuals (tail) and fish caught are snagged,gilled, wedged and entangled hereinafter abbreviated as SGWE. Data wereanalyzed, namely the amount of catches and how to Rasbora sp caught in gill netsby using completely randomized design (CRD), with three treatments and 10repetitions. Webbing different obtainable catches Rasbora sp the most is the whitewebbing that as many as 234 fish with a weight of 6,027 grams, and the least isthe blue webbing as much as 78 tails, weighing 2,078 grams. The results ofANOVA for the number and weight of fish catches Rasbora sp obtained Fhit>Ftab the meaning of there is a significant effect between treatments wereattempted. The white color is more effective fishing gear to catch fish (Rasborasp) using gill nets.Keywords: webbing, gill nets.

Abstract

The effect of types of natural food and their combinations on growth and survival rate of tambaqui (Collossoma macropomum) larvae was conducted at the Fish Hatchery and Breeding Lalboratory, Faculty of Fisheries and Marine Sciences, University of Riau in 18-L recirculating water system aquaria for 6 weeks rearing period. Six-days old larvae were stocked at density of 30 larvae/ aquarium and fed with Artemia nauplii for 6 weeks (treatment 1), water fleas 6 weeks (Treatment 2); tubifex worm 6 weeks (Treatment 3); Artemia nauplii 3 weeks followed by tubifex worm 3 weeks (treatment 4); water fleas 3 weeks followed by tubifex worm 3 weeks (Treatment 5) and Artemia nauplii 2 weeks, followed by water fleas 2 weeks and lasted by tubifex worm 2 weeks (Treatment 6). The weight gain (2.2 g) and specific growth rate (9.75%/day) were significantly higher for larvae fed with tubifex worm for 6 weeks than those fed with artemia and water flea or their combinations. Therefore, the survival rate of larvae was best (74.4%) when fed with either artemia nauplii followed by tubifex worm or water flea followed by tubifex worm.Key words: Natural food, artemia nauplii, water flea, tubifex worm, collossoma macropomum larvae

Abstract

The effect of combination of stocking density and food types on gonad maturity and egg quality of hard lipped barb (Osteochillus hasselti CV) was conducted from April to June 2015 at the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Sciences University of Riau. The broodstocks were reared in the 300-L cages placed in 3x2x1 m concrete tank for 80 days rearing period. The treatments were stocking density 20 fish/cage fed on tubifex worm (SD-20-TB), SD 20 fed on pellet dry feed (PL); SD-20 fed on PL+Vit E; SD-30 TB; SD30 PL; SD30 PL+VitE; SD40, TB; SD40 PL and SD40 PL+VitE. Fish stocked at 20 fish fed on PL+VitE produced the best result in term on the number of Fish reached at mature stage (Maturity Stage IV), (50%), fecundity (360 eggs/g fish) , Gonado Somatic Index (GSI, 14.7%), egg diameter (0.94 mm) and percent egg maturity was 75%. Temperature range of 29-30 oC, pH 5-6, and dysolved oxygen of 2.43-3.18 mg/L. Key words : Oseochillus hasselti; stocking density; feed types, Vitamin E, gonad maturity, egg quality

This research was conducted on February 23th until March 23rd 2015 held at Brackishwater Aquaculture Development Center Jepara, Central of Java. This research aimed to know the growth and survival rate of Grouper (Cromileptes altivelis) with different combination and percentage treatment of feed. The method used in this study was an experimental method with Completely Randomized Design (CRD) with one factor and three replication there were, P1 (90% fresh trash fish ; 10% pellet), P2 (70% fresh trash fish ; 30% pellet), P3 (50% fresh trash fish ; 50% pellet). In this research were used a grouper with total length 5cm and total weight 2,5 g, were than kept in plastics tank with 30 cm diameter and 18 cm height were tied with plastic’s rope on the pipe. The results showed that different combination and percentage treatment of feed gave effects with grouper’s growth and the survival rate. The best percentage of treatment was P1 (90% fresh trash fish ; 10% pellet) with total weight 5,65 g, specific growth rate 2,34%, and the survival rate 100%.Key word: Grouper, Growth, Survival rate, Feed combination
