Overcoming this problem requires a technology that can optimize the survival and growth of the domesticated snakehead fish (Channa sp.). One technology that can be applied is the use of probiotics. This reserach aimed to examine different probiotics through feed to optimize the survival and growth of domesticated snakehead fish (Channa sp.). This research was conducted with an experimental method. The experimental design used was a completely randomized design with 4 treatments and 3 replications. The treatments were control treatment (P0), treatment with probiotic composition of Lactobacillus sp., Bacillus spp. and Nitrosomonas sp. (P1), treatment with probiotic composition of Lactobacillus casei and Saccharomyces cerevisiae (P2), and treatment with probiotic composition of Lactobacillus sp., Acetobacter, Rhodobacter sp., yeast (P3). The results showed that different probiotic feeding had a significant effect (P<0.05) on the survival parameters and different probiotic feeding compositions had no significant effect (P>0.05) on the growth parameters.

Alpheid shrimp species can be used as an indicator to assess the quality of the environment in mangrove areas. The discovery of shrimp species from the Alpheid group adds to the list of biodiversity in the mangrove area of Kuala Langsa. Biodiversity of a high number of species in this group of shrimp is usually found in mangrove areas with muddy sand beaches. This is because, this type of shrimp has a habit of living in muddy areas. The living zone of this type of shrimp is almost the same location as the type of crab that is wrapped like the Scylla serrata group. Mangrove area kuala langsa although it has mangrove biodiversity that is relatively high. Kuala Langsa mangrove forests are dominated by the Rhizoporaceae group, which is a type of vegetation that is effective as a sediment trap from the direction of the river estuary while holding abrasion from the direction of the sea. In the current year there is also a condition of decrease in the number of large trees. This is caused by the harvest of mangrove wood to produce charcoal for fuel purposes. This condition will slowly make the function of the ecosystem decrease. Where the role of ecosystems provide living niches for aquatic organisms is decreasing. Land clearing of certain areas of the mangrove area for physical infrastructure purposes such as the construction of restaurants, settlements, roads, small aircraft runways, reduces the ability of the region to maintain the function of its ecosystem. The next thing is the ecological pressure for aquatic biota that has living niches in mangrove areas.Keyword: alpheid shrimp, alpheus, mangrove, ecosystem, kuala langsa, aceh","PeriodicalId":246413,"journal":{"name":"JURNAL PERIKANAN TROPIS","volume":"288 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125030121","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}
