Conservation Management Model of Subayang River in the Kampar Regency, Province of Riau based on Local Wisdom using Belida Fish (Chitala sp.) as Bioindicator

This research was conducted on the Subayang River in Kampar Regency, Riau Province, Indonesia, from January to December 2019. This research aims to determine the physical and chemical water characteristics of the Subayang River and the trend of the Belida fish (Chitalla sp.) population for constructing a river conservation management model based on local wisdom. To investigate the water's physical characteristics, a water sample was acquired from the Subayang river on three stations (upstream, middle stream, and downstream). The water sample was collected on each station iteratively at three different points at the river stream's left, middle, and right sides. The trend of Belida fish population data was gathered from interviews with the fishermen. Moreover, interviews with the traditional figure of the society around the Subayang river were also conducted. Then, the conservation model of the Subayang river was constructed by analyzing the interview and the population of Belida fish results using a system dynamic model. The investigation of the water’s physical and chemical properties shows that the Subayang river has a suitable environment for the growth of Belida fish. However, the Belida fish population trend in the last four years tends to decrease. The existence of "lubuk larangan" and "pantang larang adat", are local wisdom that gives a positive affection towards the Belida fish population. Those traditional rules can restrict citizens from doing illegal fishing which hardly affects the Belida fish population

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

PENGARUH PERENDAMAN rGH TERHADAP SINTASAN DAN PERTUMBUHAN LARVA IKAN GABUS (Channa striata)

Ikan gabus memiliki nilai ekonomis penting bagi masyarakat melayu. Namun dalam budidayanya masih mengalami kendala yaitu pertumbuhannya lambat.  Beberapa pendekatan telah dilakukan untuk memacu pertumbuhan, salah satunya adalah dengan perendaman hormon pertumbuhan rekombinan (rGH).  Tujuan kajian ini untuk mengevaluasi perendaman hormon rGH terhadap sintasan dan pertumbuhan larva ikan gabus dengan dosis berbeda. Penelitian ini  menggunakan rancangan acak lengkap dengan 4 perlakuan dan 3 kali ulangan, dengan ukuran larva 0,7±0,00 cm dengan padat tebar 2 ekor/L. Dosis perendaman larutan hormon rGH pada penelitian ini adalah 0, 1,5, 2 dan 2,5 mg/L, setiap perlakuan direndam selama 1 jam dengan padat tebar 6 ekor/L. Perendaman larva ikan gabus menggunakan dosis berbeda hormon rGH berbeda berpengaruh terhadap pertumbuhan bobot dan panjang, laju pertumbuhan spesifik, sintasan serta bobot biomassa larva ikan gabus secara sangat nyata (P<0,01). Dosis rGH yang optimal untuk perendaman larva ikan gabus yaitu 2,5 mg/L (P4) dengan peningkatan pertumbuhan bobot 2,83 g, pertumbuhan panjang 2,72 cm, laju pertumbuhan spesifik 3,11%, sintasan 16,67% dan bobot biomassa 83,53g jika dibandingkan dengan perlakuan kontrol.Snakehead fish is an economic fish in Malay society. The Problems of cultivation this fish are slow growth and low survival rate. Some approaches to stimulate the growth of fish has been done, one of the ways was by immersion rGH.  The research aimed was to evaluated the immersing effect of rGH hormone with different doses on the survival and growth of snakehead fish larvae. This research was carried out with a completely randomized design with 4 treatments and 3 replications, the larvae used measuring 0.7±0.00 cm with 2 fish/L on a stocking density. Dose of rGH hormones in this study were 0, 1.5, 2 and 2.5 mg/L, immersion of rGH done for 1 hour with a stocking of 6 fish/L for each treatment. The result showed that, rGH could increase survival rate and growth (P<0.01) of snakehead larvae. The optimal dose of rGH for immersing snakehead larvae was 2.5 mg/L (P4) with an increase in weight growth of 2.83 g, length growth of 2.72 cm, specific growth rate of 3.11%, survival rate of 16.67%. and biomass weight of 83.53g when compared to the control treatment

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
