Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 2)
Type: Journal Article
A method is described for the determination of the selection curve of fishing gear from the shape of the ascending arm of a length-converted catch curve and growth parameters.
The capture and culture of postlarval coral reef fish: potential for new artisanal fisheries

Type: Journal Article
A brief description of fisheries development in Djibouti is given, with emphasis on the major constraints that have to date limited the increase of fishing effort. Estimates of L sub( infinity ) obtained through Wetherall ...
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 1)
Type: Journal Article
A number of methods are available with the help of which total mortality (Z) can be estimated from length-frequency data. Thus it is possible to obtain reasonable estimates of Z from the mean length in a representative ...
Maintaining diversity of integrated rice and fish production confers adaptability of food systems to global change
Type: Journal Article

Managing by-catch and discards : how much progress are we making and how can we do better?
Type: Journal Article
There appears to be considerable potential for further reduction in global by-catch. This reduction is most likely to be achieved by focusing even greater attention on the technical, regulatory and social approaches that ...
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (III: conclusion)
Type: Journal Article
A method is described for the determination of the selection curve of fishing gear from the shape of the ascending arm of a length-converted catch curve and growth parameters.
