Keberhasilan dan Pertumbuhan Larva Ginogenesis Ikan Selais (Ompok Rhadinurus Ng ) dengan Kejutan Suhu Dingin

Penyediaan benih ikan berkualitas dan berkesinambungan menjadi faktor penting dalam peningkatan budidaya ikan. Pengembangan usaha budidaya akan mengalami hambatan tanpa diberengi oleh ketersediaan benih yang cukup dan berkualitas baik. Salah satu cara yang dapat ditempuh untuk menyediakan benih yang berkualitas unggul adalah dengan jalan perlakuan Ginogenesis. Penelitian ini telah dilakukan pada bulan Mei-Agustus 2014 di Laboratorium Pembenihan dan Pemuliaan ikan Universitas Riau. Penelitian ini bertujuan untuk mengevaluasi pengaruh lama penyinaran dan lama kejutan suhu dingin serta pertumbuhan benih ginogenesis ikan selais (Ompok rhadinurus). Metode yang digunakan adalah metode eksperimen, dengan perlakuan lama penyinaran Ultraviolet terhadap sperma ikan dan lama kejutan dingin terhadap telur setelah pembuahan 1 menit pada suhu kejutan dingin 5 oC. Sperma berasal dari ikan patin (Pangasius hypopthalmus), sedangkan telur berasal dari ikan selais (O. rhadinurus). Hasil eksperimen menunjukkan bahwa perlakuan terbaik adalah lama penyinaran 3 menit setelah terjadi pembuahan 1 menit dan lama kejutan dingin 3 menit pada suhu dingin 5oC. Sedangkan pertambahan bobot dan panjang mutlak K-2H dan G-2N meiotik tidak jauh berbeda

This research was conducted over 60 days, starting on April 20 until June 8 2015, at the Hatchery and Breeding Laboratory at Fisheries and Marine Science Faculty, University of Riau. This research aims to determine the effect of sGnRH-a + domperidone with different doses of the ovulation stimulation and the eggs quality of Nilem Carp (O. hasselti CV) which is the first step of research and then the best dosage obtained through observations in the first step will then be injected against gonads mature female brood and then will spawn with the male injected with the best dose (0.4 ml/kg body weight) through research "sGnRH-a + domperidone With Different Doses for Volume, Concentration and Cement Quality of Nilem Carp (O. hasselti CV) as the second step of this research. The results showed that sGnRH-a + domperidone at a dose of 0.6 ml/kg body weight were significant (p<0,05) for the latent time, total eggs ovulation, egg diameter increase, eggs maturity and ovisomatik index value, with the best results for the latent time (6.15 hours), total eggs ovulation (242 eggs/g gonads), egg diameter increase (0.9125 mm), eggs maturity (20 %) and ovisomatik value index (14.75 %). Results of the second step resulted in average: fertility rate (81.33 %), hatching rate (81.76 %), absolute length growth (1.91 cm), absolute weight growth (0.27 g), daily growth rate (10.17 %) and the rate of survival (95.1 %)

This study was conducted for 28 days from 13 Mei until 9 Juni 2014, In Hatchery and Fish Breeding Laboratory of Fisheries and Marine Sciences University of Riau. The aim of study was to determine of the effect of longeth radiation and cool shock differently toward ginogenesis shealtfish (Ompok rhadinurus Ng) fertilized by spermatozoa catfish (Pangasius hypophthalamus). The experiental used in this study with 1 factor and 10 treatments. The treatment were density of control hybridization and spermatozoa radiation with ultraviolet light (1,2, and 3 minutes) and then performed for 1 minute after conception with cool shock 5oC (1,2 and 3 minutes). The best treatment was combination 3 minutes while radiation performed for 1 minute fertilization with cool shock 5oC for 3 minutes (P3F1K3) with a success percentage of 100%. The water quality parameters along the research period were recorded as temperature 25 – 27oC, pH 5 – 6, and dissolve oxygen ( DO ) 5- 7,5 mg/l respectively

The Influence of Injection SGnRH+Domperidon by Different Dosage to Egg Quality and Hatching of Betok (Anabas Testudineus)

The research was conducted from Oktober to November 2014 at Fish Breeding and Hatchery Laboratory Fisheris and Marine Science Faculty of Riau University. It was aim to know the influence of sGnRH+Domperidon injection by different dosage to egg quality and hatching of betok. It the research experiment method was applied with four treatmens and tree replications. The treatment injection by fisiologis solution 0,9 %, injection by sGnRH+Domperidon 0,5 ml/kg. 0,7 ml/kg and 0,9 ml/kg weigh of fish. The result showed that treatment with different dosage of sGnRH+Domperidon provide a significant influence on total of latency time of spawning, eggs ovulation/g weight of fish, eggs diameter, fertilization, egg hatchability and survival rate of larval. The best result was got from 0,5 ml/kg dosage with latency time 6,49 hour, total eggs ovulated 212/g weight of fish, accretion diameter of egg 0,184 mm, egg fertilized 75,11 %, egg hatchability 78,09 % and survival rate of living larvae was 82,36 %.Water quality during experiment was always in good condition for living

Effect of Types of Natural Food and Their Combination on Growth Dab Survival Rate of Tambaqui (Colossoma Macropomum) Larvae

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
