Growth, mortality and recruitment of commercially important fishes and penaeid shrimps in Indonesian waters
Type: Report
Estimates of von Bertalanffy growth parameters were derived through application of the ELEFAN I program to lengthfrequency data from 52 stocks and 36 species of commercially important bony fishes from Indonesian waters, ...
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 ...
Developments in the breeding of cultured fishes
Type: Book Chapter
The controlled breeding of finfish for culture is reviewed with special refer-ence to recent developments and persistent problems. Freshwater species are at present cultured on a much larger scale than brackishwater 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. ...
On length-weight relationships. Part I: Computing the mean weights of the fish in a given length class
Type: Journal Article
When working with length frequency date, we often need to compute the mean weights of the fish in the various classes. This article outlines one of the methods used.
The pattern of fish trade
Type: Journal Article
An account is given of the general pattern regarding trade in fish products. Developed countries import more than they export, whereas developing countries import less. Problems involved and remedies are discussed, considering ...
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 ...
Rice terraces and fish: integrated farming in the Philippines
Type: Journal Article
A brief account of rice fish culture in the Ifugao Province, northern Luzon, Philippines was presented.
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).
