Abstract

Belida fish (Notopterus notopterus, Pallas 1769) is one of Indonesia's endemic fish which is often found in swamp waters having high economic value. The population of belida fish until now has decreased due to the high fishing activities in nature. To maintain the population of belida fish in order to remain sustainable from nature  is by cultivation activities. One of  important aspect in belida fish culture is the determination of stocking density used. This study aims to determine the optimum stocking densities in the belida fish farming activities. This research was conducted from June to August 2019 in the fish pond of Sungai Paku Village, Kampar Kiri Subdistrict, Riau. The design used was a completely randomized design with 3 levels of treatment and 3 replications. The treatment used in this study was stocking density consisting of 5, 10 and 15 fish / m3. The results showed that the 5 fish / m3 stocking density treatment produced the optimum fish growth with absolute length growth value (11.48 cm), absolute weight growth (48.73 g), daily growth rate (2.83%), survival rate (86 , 7%), fat retention 1.27% and protein retention value 19.83%.

Abstract

Natural food enrichment, especially water fleas, is an important effort in improving the performance of freshwater fish larvae. The enrichment process that will be carried out is influenced by several factors that need to be considered, namely the dose of vitamin supplements, pH, and time of enrichment so that the vitamins can be absorbed by the intestines and the nutritional value of water fleas increases. This study aims to examine and determine how the effect of the dose of viterna, water pH, and time of enrichment on the rate of the fulfillment of the gut of water fleas by viterna. This research was conducted from January 3 to 7, 2022 at the Laboratory of Fish Hatchery and Breeding, Faculty of Fisheries and Marine Science, Riau University. The treatment in this study is the rate of the fulfillment of the water fleas' intestines during the water fleas natural feed enrichment technique which was carried out with three different pH test factors, different doses, and different enrichment times. The results showed that the water fleas enriched for 5 hours, at a pH of 7 and a dose of 60 ml/L of viterna showed the best filling rate of the water fleas' intestines at 100%, and the water fleas' intestines were filled with viterna compared to other treatments.
