Abstract

One of the local fish (native species) that is popular with the public and has quite good market prospects in Aceh is the seurukan fish (Osteochilus sp.). Seurukan fish cultivation technology with a recirculation system needs to be developed so that its potential can be utilized optimally. This research aims to evaluate production performance and determine the optimal stocking density for rearing seurukan fish (Osteochilus sp.) in a recirculation system. This research was conducted by experimental method. The experimental design used was a completely randomized design (CRD) with three treatments of stocking density and each treatment was repeated four times. The treatments are P1 (5 fish/m2), P2 (10 fish/m2), and P3 (15 fish/m2). The rearing period for Seurukan fish lasts for 50 days. The parameters tested during the research included biological parameters consisting of survival, absolute growth rate, feed conversion ratio, weight diversity coefficient, and water quality parameters including temperature, pH and dissolved oxygen. The results showed that the seurukan fish reared at different stocking densities using a recirculation system had a significant effect on the absolute growth rate and the coefficient of variation in weight. The best treatment in this study was 5 fish/m2, with a survival rate of 100%, an absolute growth rate of 0.04 g/head/day, a feed conversion ratio of 1.63, and a coefficient of variation of weight of 17.99%.Key words: production performance; seurukan fish; recirculation system; stocking density

Abstract

AbstractThis study aims to determine the effect of lysine and probiotic supplementation in artificial feed based on local raw materials on feed quality and feed conversion ratio of bileh fish (Rasbora sp.). This research was carried out from August to September 2023 at the Hatchery and Laboratory of Systems and Technology and the Aquaculture Environment, Faculty of Fisheries and Marine Sciences, Teuku Umar University. In this study, bileh fish measuring 2 - 2.5 cm long were used as test fish. The experimental design used was a non-factorial Completely Randomized Design (CRD) with 4 treatments and 3 replications. The level of treatment applied in feed formulation is feed based on local raw materials as a control (P0), feed based on local raw materials with 1.2% lysine supplementation (P1), 1.4% (P2), 1.6% (P3), 1.8 % (P4) and probiotics 15 ml/kg feed. Feed is given at satiation 3 times a day. The test parameters observed were the quality of the feed produced, daily growth rate and feed conversion ratio of bileh fish (Rasbora sp.). The research results showed that lysine and probiotic supplementation in artificial feed based on local raw materials gave the same response to the quality of the feed produced, but had a significant effect on the daily growth rate and feed conversion ratio of bileh fish. The best daily growth rate and feed conversion ratio were obtained in the P3 treatment.Keywords: Artificial feed based on local raw materials; feed quality; feed conversion ratio; Rasbora sp.

Abstract

Bileh fish is a type of freshwater fish that is sought after by the people of Aceh because it has a delicious taste and is quite tasty. Bileh fish is a local fish species that has the potential to be developed as an aquaculture commodity and its population must be preserved from overfishing. The aim of this research was to determine the effect of different feeding frequencies on the growth of bileh fish fry (Rasbora sp.). This research used a non-factorial completely randomized design (CRD) method consisting of 4 treatments and 3 replications each, namely the frequency of feeding 1 time/day (P1), feeding 2 times/day (P2), feeding 3 times/day day (P3) and feeding 4 times/day (P4). The feed given is commercial feed PF 500 with 39% protein. The parameters observed included survival rate, length growth, weight growth, daily growth rate, feed efficiency and water quality. The results showed that different feeding frequencies had no significant effect on survival rate, absolute length and daily growth rate of bileh fish (Rasbora sp.). However, it has a real effect on weight growth and feed efficiency. The best feeding frequency to optimize the weight growth of bileh fish (Rasbora sp.) is in the P3 treatment with a frequency of 3 times/day.Keywords: Feed Efficiency; Feeding Frequency; Growth; Rasbora
