In addition to the seagrass community, there are also distinctive coastal communities such as mangroves and coral reefs. Coastal resources in this region are often used by the local community as a food source and have been used as a place of recreation and hotels as well. This is the reason for this study to find out the existence of gastropods on the seagrass beds in the Tongkeina area. It is expected that this study will provide information on the development and existence of the gastropods in coping with the pressure due to the construction of the hotel several years before.

Hasil yang diperoleh adalah pakan uji pada perlakuan D sangat memberikan hasil berbeda yang sangat nyata dengan ketiga pakan lainnya (A, B dan C) dalam hal pertumbuhan berat, laju pertumbuhan dan efisiensi pakan; namun pada uji lanjut Duncan, hasil statistik menunjukkan bahwa pakan C dan pakan D lebih efisien dibandingkan pakan A.Kata kunci: akuakultur, pakan buatan murah, silase, pertumbuhan, ikan nila","PeriodicalId":202638,"journal":{"name":"JURNAL PERIKANAN DAN KELAUTAN TROPIS","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128228954","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}
