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 ...
Predicting food consumption of fish populations as functions of mortality, food type, morphometrics, temperature and salinity
Type: Journal Article
A large data set of relative food-consumption estimates (Q/B) of marine and freshwater fish populations (n = 108 populations, 38 species) is documented and used to derive a predictive model for Q/B, using asymptotic weight, ...
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 ...
Tabular data on marine fishes from Southern Africa. Part II: growth parameters
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".
Competition between fisheries and marine mammals for prey and primary production in the Pacific Ocean
Type: Journal Article
The degree of competition between fisheries and marine mammals in the Pacific Ocean was estimated for 7 statistical areas defined by the Food and Agriculture Organization of the United Nations (FAO). Catch statistics ...
