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.
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).
