Fishery statistics on the microcomputer: a BASIC version of Hasselblad's NORMSTEP program
Type: Journal Article
This paper provides an outline of a mathematical method to analyse overlapping normal distributions. Separations of mixtures of normal distributions is frequently required in fisheries biological analysis, as in the case ...
Kuwait's finfish catch three times more shrimp than its trawlers
Type: Journal Article
Assessments made of shrimp catches in Kuwait and available stocks indicate that finfish eat a large majority of theshrimp available. Management measures to be taken in order to reduce this predation problem are considered.
Indices of overall growth performance of 100 tilapia (Cichlidae) populations
Type: Conference Paper
Four indices for comparing the overall growth performance of fishes ( omega , P, Phi , and Phi ') proposed by various authors are assessed, based on growth parameter estimates in 100 populations of tilapia in 15 species of the ...
Electronic length frequency analysis: a revised and expanded user's guide to ELEFAN 0, 1 and 2
Type: Manual
This guide presents an updated and extended version of the ELEFAN 0, ELEFAN 1 and ELEFAN 2 programs for Electronic LEngth Frequency ANalysis. These programs can be used to estimate the parameters of a (seasonally oscillating) ...
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, ...
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 ...
On improving operation and use of the elefan programs. part 2, improving the estimation of L
Type: Journal Article
Four simple approaches which rely on slightly modified versions of ELEPHAN I and/or II are given for the estimation of length of fish.
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).
