In this regard, cultivation needs to be done to meet the demands and demands of the community. The study aims to determine the long-term influence of thyroxine and the long-time immersion of thyroxine is best used to spur the growth and livelihoods of white tilapia larvae. This research was conducted in the Siwarak Fish Seed Hall (BBI) Ungaran, Semarang, Central Java, in October-November 2018. The test fish used are white tilapia larvae that have loose egg yolks. Maintenance is done for 35 days. This study uses 4 treatments and 3 repeats ie A soaked thyroxine 0.1 mg/L for 0 hours (control), B soaked thyroxine 0.1 mg/L for 12 hours, C soaked thyroxine 0.1 mg/L for 24 h, D soaked thyroxine 0.1 mg/L for 36 hours. The variables measured include, absolute weight growth, absolute length growth, specific growth rate, sustainability, and water quality. The best value of absolute weight growth is C 1.05 ± 0, 21g. The best value of the specific growth rate is C 10,20 ± 0.54%/day. Best value of absolute length growth is C 36,03 ± 2, 59cm. The best value of a livelihood is B 92,22 ± 0.96% but has no real effect on all treatment. Thus a long time the immersion of thyroxine has a noticeable effect on absolute weight growth, specific growth rate, and the absolute long growth of white tilapia larvae but does not affect the degree of livelihood of white tilapia larva. The length of the best soaking time to improve the growth and livelihoods of white tilapia larvae is 24 hours.Key words: Immersion Time; Thyroxine; Growth; Survival; White Tilapia

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
