The transplanted coral fragments range in size from 3-5cm. The success rate of coral life was 100% for 9 weeks, length growth for 9 weeks was 0.0733 cm with an average growth of 0.0067 cm/week. Air quality is an important factor in supporting the survival rate of transplanted corals on a laboratory scale. The air quality must be in accordance with the coral's original habitat so that the transplanted corals can live well. Air quality observed in the form of temperature 33 ̊C, Salinity 25-40‰, pH 6.5-7.5 and DO >5. In addition to air quality, an important factor in coral transplantation is the choice of substrate. The substrate debris in this study showed good results for coral transplantation.","PeriodicalId":17689,"journal":{"name":"Jurnal Kelautan: Indonesian Journal of Marine Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79200436","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the variation of their current speed, current direction, and transport during the ENSO phases on La Nina in 2010-2011 and El Nino in 2015-2016. The data used were the Marine Copernicus reanalysis data of u and v components of current velocity at 155 m and 266 m of depth. The data were processed by using GrADS to see the direction and speed of the current as well as by calculating the ITF transport. During La Nina, both at 155 m and 266 m of depths were found the eddy patterns. When El Nino occurred, the direction of currents in Maluku Sea was different from La Nina conditions, while the direction of currents in Halmahera Sea had no differences. Current velocity in both oceans at each depth was lower during El Nino than La Nina. The condition of ITF transport in the Maluku Sea during La Nina was dominated by southward movement with a smaller value than during El Nino which generally moved northward meanwhile in the Halmahera Sea had the opposite condition.Keywords: current speed, current direction, ENSO, ITF, transport","PeriodicalId":17689,"journal":{"name":"Jurnal Kelautan: Indonesian Journal of Marine Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-02-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86713050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research was conducted for 28 days using seabass with 7-8 cm size, with a container that have 20 L volume and the density of 10 fish. The method used in this research was an experimental method using completely randomized design with 4 treatment and 3 replication, P1: control , P2:  rGH hormone 0.5 mg/ml, P3: rGH hormone 0.6 mg/ml, P4: rGH hormone 0.7 mg/ml. The parameters observed were absolute weight and lenght growth, specific growth rate, feed conversion ratio (FCR), feed utilization efficiency (EPP), and survival rate (SR). Data were analyzed with ANOVA and Duncan ’s test. The result showed that differences in the concentration of the addition of rGH hormone in commercial feed could effect all the research parameters except feed conversion ratio and survival rate . Addition of the rGH hormone with a concentration of 0.6 mg/ml (P3) is the best concentration because it provides an absolute weight growth rate of 4.03 g, an absolute length growth rate of 1.90 cm, a specific growth rate of 1.32% and feed utilization efficiency of 29.56%.
