A multiple regression model for predicting the food consumption of marine fish populations
Type: Journal Article
The construction of trophic (food web) models of ecosystems, as needed for both theoretical and practical purposes such as fisheries management, requires estimates of food consumption (Q) by each of the various species ...
ICLARM's Resource Development and Management Program: the Tropical Stock Assessment Research Project
Type: Journal Article
The project was conceived to identify and overcome the major constraints preventing the development of stock assessment techniques appropriate to tropical stocks. These constraints are listed and the project's programme of ...

Type: Journal Article
This contribution presents von Bertalanffy growth parameter estimates for 28 species of marine fishes derived from growth curves in R. van der Elst's "Guide to the Common Sea Fishes of Southern Africa".
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 ...

Training courses in fish stock assessment: the past and the future
Type: Journal Article
Ideally, all countries with major marine and/or inland capture fisheries should have a few scientists specialized in stock assessment techniques to lead research programs and to analyze the results for management and ...
Management of multispecies stocks: a review of the theory
Type: Journal Article
The multitude of species contributing to the catch of the demersal fisheries of Southeast Asia, combined with an acute lack of knowledge on the biology of these species and the scarcity of good statistical data on the ...

Fish production, catches and the carrying capacity of the world oceans
Type: Journal Article
A brief review of the status of the world fisheries is presented with emphasis on the differences between catches (= landings + bycatch), biological production of fish, and predation (= production - catches). The ECOPATH ...
