Type: Journal Article
A limnological study of the artificial fish pond and an analysis of the stomach contents of pacu (Piaractus mesopotamicus) larvae of 2 to 45 days age were made for a period of 45 days to evaluate their feeding preferences. ...
Escalation in shrimp production in the Sierra Leone industrial fishery
Type: Journal Article
Applying Turkey's jackknife method on MSY estimates from the surplus production models of Schaefer and Fox showed that the optimum yield for shrimps in industrial fishery in Sierra Leone is estimated at 2,686.8 t with ...
Chemoreception studies in relation to feeding responses in the marine shrimps H. Milne Edwards (Penaeus indicus) and Miers (Metapenaeus dobsonii)
Type: Journal Article
A study of chemoreception in relation to feeding and other factors involved showed that feeding behavior in shrimps can be triggered by chemical stimuli. However, Penaeus indicus and Metapenaeus dobsoni differ significantly ...
