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 ...
The population dynamics of Nemipterus marginatus (Cuvier & Val.) off western Kalimantan, South China Sea
Type: Journal Article
The following parameter values are derived for a West Kalimantan (West Borneo) stock of the threadfin bream, Nemipterus marginatus : L infinity = 24.5 cm (L.T.), W infinity = 210 g, K = 0.42, t = -0.41 and M = 1.73. ...
Growth, reproduction and mortality of the sea hare Dolabella auricularia (Gastropoda: Aplysiidae) in the Central Visayas, Philippines
Type: Journal Article
The growth parameters W infinity and K of the von Bertalanffy growth equation were estimated from size-frequency data of the sea hare D. auricularia using an objective, computer-based method. The results obtained from two ...
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 ...
A simple method for estimating the food consumption of fish populations from growth data and food conversion experiments
Type: Journal Article
A multiple-regression extension of the basic model is presented which accounts for the impact of factors other than body weight on values of K1 and p. This method is illustrated with an analysis of data on dab (Limanda limianda).
A mechanism for the juvenile-to-adult transition in fishes
Type: Journal Article
The mechanisms used by physiologists and fishery biologists to explain why fish become mature are shown to be wanting. The hypothesis is presented that diminishing oxygen supply per unit weight serves in growing fish as ...
An atlas of the growth, mortality and recruitment of Philippine fishes
Type: Report
This atlas presents the results of a detailed analysis of length-frequency data collected from 1957 to 1981 throughout the Philippines, covering 23 families, including 34 genera and 56 species representing 112 stocks ...
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.
