Performance Of Milkfish (Chanos chanos) Cultured by Different Stocking Density in Floating Net Cages Lake Batur, Trunyan Village, Bali

Lake Batur is the largest lake in the island of Bali. Lake Batur is widely used by the community in the aquaculture sector, namely floating net cage cultivation. The research aims to determine the influence of different stocking density on the growth rate and survival rate of the milkfish (Chanos chanos) in the 4 x 1 meters floating net cages in Lake Batur, Trunyan village. Data collection was done every two weeks during two months observation, from January 2020 – March 2020. The research used a complete random design consisting of three treatments and three replications of each treatment, which the treatment A of 15 fish/0.25m3, treatment B of 20 fish/0.25m3, and the treatment C of 25 fish/0.25m3. Measurements of fish length, fish weight, and water quality were done in situ. The results showed that the difference in stocking density had no effect on the absolute length, but those difference had an effect on the specific growth rate (SGR) and the survival rate of the fish. Treatment B resulted a maximum value of the growth rate, with an absolute length value of 0.69 ± 0.115cm/2 month and SGR 1.02 ± 0.095%/day. The fish survival rate at treatment A resulted in the highest value of 89 ± 3.46%/2 month. The value of water quality during the study were temperature of 25.9 ± 0.8oC, DO of 8.3 ± 0,1 mg/L, pH of 9.4 ± 0.2, and TDS of 995.5 ± 70.8 ppm.

Stocking density is an important factor in cultivation, it can save land use, and increase the efficiency of fish farming. The purpose of this research was to determine the different density information on tilapia seeds measuring 2-3 cm as an alternative to using tilapia (O. niloticus) seeds 7-9 cm in size so that they can be developed in Batur Lake. The research was conducted in January - March 2020 in the floating net cages in Trunyan Kintamani village, Bangli, Bali. The research used a completely randomized design method with three treatments and three repetitions. The Tilapia seeds used are 2-3 cm with different stocking densities, 100 ind/m3, 150 ind/m3, and 200 ind/m3. The parameters observed were SGR (Specific Growth Rate), absolute growth, SR (Survival Rate), FCR (Feed Conversion Ratio), and water quality including temperature, DO, pH, TDS. The results of this study indicated that stocking density did not have a significant effect on the growth and survival rate of tilapia seeds, because the temperature was too cold so that the tilapia seeds failed to adapt properly at the beginning of stocking and the physiological conditions of the fish were disturbed so that the fish experienced stress and went to died. Water quality parameters measured include temperature with a range value of 25.86-25.880C, pH with a range value of 9.08-9.13, DO (Dissolved oxygen) with a range value of 7.9-8 mg/L, and TDS (Dissolved solids) with a range value of 1040.25-1041.58 mg/L.

Environmental problems due to aquaculture occur along with the increase in aquaculture production. IMTA is one system used as a solution in dealing with environmental problems. The objective of this study was to analyze the growth performance, survival rate, and production of the main commodity (tilapia) and the supporting commodities (Peres, Lemeduk, and Depik) which are applied through the application of integrated multi-trophic aquaculture (IMTA) using floating net cages. This research was conducted at the Lukup Badak Fish Seed Center, Central Aceh from July to August 2020. The experimental design used was a completely randomized design (CRD) with 4 treatments and 3 replications, namely: A (tilapia), B (tilapia and peres), C (tilapia and lemeduk), and D (tilapia and depik). ANOVA test results showed that the IMTA system had a significant effect on absolute length growth, absolute weight growth, specific growth rate (SGR), survival rate, and biomass production of tilapia (P0.05). The results showed that maintenance for 42 days produced the highest value in treatment B with the increase in absolute length growth (4.26cm±0.24); absolute weight growth (5.47g±0.45), specific daily growth rate (2.28%/day±0.13) and the highest tilapia biomass production (480g/0.5m2±19.25). The highest survival rate was found in treatment C (82.42%±2.28). It was concluded that the treatment using the IMTA system was better than without the IMTA system.Keywords:IMTAWater qualityGrowth performanceTrophic interactionBiomass production

Ikan semah (Tor douronensis) termasuk salah satu spesies dari genus Tor yang memiliki nilai ekonomis tinggi. Untuk meningkatkan produktivitas, informasi pertumbuhan benih yang dipelihara pada sistem budidaya karamba jaring apung (KJA) perlu dilakukan karena ikan semah umumnya dibudidayakan pada kolam dengan air yang jernih. Penelitian ini bertujuan untuk mendapatkan informasi laju pertumbuhan benih ikan semah generasi pertama dengan perlakuan padat tebar yang berbeda pada sistem pemeliharaan KJA. Percobaan dilakukan di Waduk Cirata, Cianjur, Jawa Barat selama lima bulan. Ikan uji (panjang total: 7-8 cm; bobot: 5-6 g) dipelihara di KJA (padat tebar 50, 75, dan 100 ekor/m3 dengan tiga kali ulangan). Pakan apung komersial dengan kadar protein 40% diberikan sebesar 6% per biomassa yang diberikan dua kali sehari. Parameter yang diamati yaitu pertumbuhan bobot mutlak, sintasan, laju pertumbuhan spesifik (SGR), dan biomassa. Hasil percobaan menunjukkan bahwa perlakuan padat tebar 50 ekor/m3 menghasilkan pertumbuhan terbaik dengan bobot akhir 15,89 ± 1,43 g; pertambahan mutlak 10,48 ± 1,41 g; sintasan 94,67 ± 4,6%; dan SGR 0,75 ± 0,04%. Dari hasil penelitian ini, padat tebar 50 ekor/m3 merupakan kondisi yang terbaik untuk pemeliharaan benih ikan semah di KJA. Hasil penelitian ini dapat dijadikan informasi awal tentang potensi budidaya ikan semah dengan sistem budidaya KJA perlu dikembangkan di masa yang akan datang.Semah mahseer (Tor douronensis) is a species from the genus Tor and highly valued in local and national markets. Nevertheless, the fish production from net cage is currently limited. In order to increase its productivity, research on the growth of semah mahseer fingerlings reared in floating net cage systems needs to be carried out as this species is predominantly cultured in the clean water ponds. This study was conducted to obtain information on the growth performance of the first generation of semah mahseer fingerlings reared with different stocking densities in a floating net cage system. The experiment was carried out in the floating net cage located at Cirata Reservoir, Cianjur, West Java, for five months. Fingerlings (total length: 7-8 cm; body weight: 5-6 g) were reared in the floating net cage (stocking density of 50, 75, and 100 ind./m3 with three replications). The fish were fed with a commercial diet (protein content of 40%) given at 6% of biomass twice a day. The parameters observed included weight gain, survival rate, specific growth rate (SGR), and biomass. The results showed that the stocking density of 50 ind./m3 had the best performance in terms of final weight of 15.89 ± 1.43 g, weight gain of 10.48 ± 1.41 g, survival rate of 94.67 ± 4.6%, and specific growth rate of 0.75 ± 0.04%. Based to the results of this study, the stocking density of 50 ind./m3 is the best condition for rearing semah mahseer fingerlings in floating net cages. The findings of this research can be used as the basic information for future aquaculture development of semah mahseer in net cages.

Culture of Tilapia (Oreochromis niloticus) with high stocking density and feeding can cause a decrease in water quality due to the accumulation of metabolic waste such as ammonia which is toxic for fish rearing. A zeolite filter is needed which can reduce ammonia levels until it is not harmful to fish survival. This research was conducted in February-April 2020 at the Aquaculture Environmental Quality Laboratory, Fisheries and Marine Faculty of Riau University. The purposed of this study was to determine the effect of using zeolite on Ammonia (NH3) and determine the appropriate dose for Tilapia (Oreochromis niloticus) rearing. The research method was a Completely Randomized Design (CRD) one factor with 4 levels of treatment (P0: Control without the use of filters, P1: Use of zeolite 5.68 g/L, P2: Use of zeolite 11.37 g/L, P3: Use of zeolite 17.05 g/L). The appropriate treatment for Tilapia rearing is P3 (Zeolite 17.05 g/L) with TAN value is 0.2616 mg/L, Ammonia 0.0018 mg/L, TAN reduction is 59%, and Survival Rate of fish is 88.88%. The value of water quality during the study were temperature 27-29 oC, pH 6.7-7.0, and DO 6.2-6.9 mg/L.
