A simple index of metabolic level in fishes
Type: Journal Article
Details are given of the use of an aspect ratio of the caudal fin of fish as an index of metabolic level. Studies have shown that this ratio, besides correlating with food consumption, also has close relationships with ...
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.
Application of information on age and growth of fish to fishery management
Type: Book Chapter
Information on the age and growth of fish is usually related to one or several of the following items: construction of age/length keys for direct use in some assessment models (e.g. Virtual Population Analysis); estimation ...
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 ...
On improving operation and use of the elefan programs. part 3, correcting length-frequency data for the effects of gear selection and/or incomplete recruitment
Type: Journal Article
One important feature of length€”frequency data that is usually ignored when data are collected for subsequent estimation of growth and various related parameter estimates is that length€”frequency data are necessarily ...
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.
