To evaluate the contribution of hatchery production to the fishery, scale pattern analysis was used to differentiate between hatchery-reared and wild fish. Scale patterns from 30–150-d-old hatchery-reared red drum fingerlings (13–35 mm total length, TL) from two hatcheries and wild red drum juveniles (<121 mm TL) were analyzed to establish a linear discriminant function. Accurate identification of 30-d-old hatchery-reared red drum ranged from 61–64%, but decreased to 35% for 60–150-d-old fish; classification rates for wild fish ranged from 63% to 70%. Correct classification of 30-d-old hatchery fish was significantly better than chance, but correct classification of wild fish was only significantly better than chance at one hatchery.

Diets containing 3, 6, and 8% lipids were fed at a rate of 3% of biomass per day. Fish grew from 68 g to 250 g in 91 d. Specific growth rates and feed efficiency ratios were not significantly different between treatments. Examination of fat levels in fillets and livers did not demonstrate any trend as lipid levels in diets decreased. The amount of fat in the viscera did not decrease with a reduction of lipid in the diets. It was concluded that lower fat levels could be used in feeds for intensive production systems if the caloric value of the diet is balanced with suitable carbohydrates. In addition, fat level in the final fillet product will not be reduced by lowering the dietary fat level in fish feed within the range of 3% to 8% lipid.","PeriodicalId":22850,"journal":{"name":"The Progressive Fish-culturist","volume":"29 1","pages":"293-296"},"PeriodicalIF":0.0,"publicationDate":"1997-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77776446","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}
