Management of humpback grouper larvae health includes larval rearing, larval feed management and larval disease control. The primary data collection method was carried out in 3 ways, namely observation, active participation and interviews. Secondary data retrieval by studying literature from various related sources. The humpback grouper larvae were reared in the hatchery to control the temperature and condition of the larvae. Larval ponds are sterilized with 3-5 ppm chlorine in the morning and rinsed thoroughly so that no chlorine remains. Larvae were reared from the age of 1 day to 45 days. Feeding the larvae was started when the larvae were 2 days old with Nannochloropsis occulata. Rotifers were given when the larvae were 2-3 days old with a density of 5 individuals/ml. Artemia was given when the larvae were 20 days old until the age of 40 days. Pellets are given when the larvae are 8-10 days old with a pellet size of level 1. The pellet size continues to increase according to the larva's mouth opening. The disease that often attacks larvae is Viral Nervous Necrosis (VNN). The characteristics of larvae infected with VNN are reduced appetite, weak movement, larvae float on the surface and lie on the bottom of the pond. VNN attacks can only be overcome by prevention. The bacteria that often attack the larvae are Vibrio alginolyticus. Vibrio alginolyticus can be treated with antibiotics or non-antibiotics. The use of antibiotics is not recommended because they have negative side effects, so you can use other alternative medicines derived from herbal plants (phytopharmaceuticals).","PeriodicalId":250719,"journal":{"name":"Journal of Aquaculture Development and Environment","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121805870","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}

Cultivation of carp (Cyprinus carpio) can be done intensively and semi-intensively by taking into account the economic value. However, from cultivation activities, the problems that were often faced in cultivation activities were the attack of dangerous types of pathogens such as parasites. Parasite was a fish disease that occurs more frequently. Parasites were organisms that live on the body of other organisms and generally have a negative effect on their host. This study aimed to identify and the prevalence of ectoparasites to determine the type and level of ectoparasite attack on carp (C. carpio) seeds and to reduce the impact of ectoparasites which was feared to reduce the amount of carp production from cultivation. The method used was a direct survey to the Local Fish Seed Center and fish farmers in the Koya Barat area. The fish used were carp in the seed phase where the fish's immune system was still weak, making it more susceptible to contracting parasites. This study showed that there were 4 types of parasites found during the study that infected carp seeds, namely Dactylogyrus sp, Gyrodactylus sp, Trichodina sp, and Lernea sp. The average prevalence rate of Dactylogyrus sp. at stations I, II, III, and IV was 25%, Gyrodactylus sp. 8.3%, Trichodina sp. 8.3% and Lernea sp. 5% with the lowest prevalence rate.","PeriodicalId":250719,"journal":{"name":"Journal of Aquaculture Development and Environment","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117327458","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}

The feed given was in the form of artificial feed (pellets) because of the practicality of its availability. However, commercially made feed was of course more expensive, and can pollute the air compared to natural feed which was easy and can be in the surrounding environment. For this reason, it was necessary to look for natural feed as an effective and efficient alternative feed to ripen the gonads of male and female swordtail. The research used a completely randomized design with 4 treatments and 3 repetitions and arranged randomly.
