A total of 957 pointhead flounder were caught. The SELECT analysis with maximum likelihood method was used to fit the different functional models, the normal, lognormal, and bi-normal model. The catch data except for entangling catch was used for calculation. The bi-normal model was found to fit the data best. For the selectivity curve on the bi-normal model, the relative length (the ratio of fish length to mesh size) with the maximum efficiency was obtained as 1.87.","PeriodicalId":9361,"journal":{"name":"Bulletin of the Japanese Society of Scientific Fisheries","volume":"9 1","pages":"174-181"},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88598239","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}
