A method to estimate the stock recruitment relationship of shrimps
Type: Journal Article
A procedure is proposed by which recruit numbers and parental biomass of shrimps stocks can be derived, given a series of catch per effort data and estimates of a few ancillary variables. In the Gulf of Thailand, shrimp ...
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 ...
Length-converted catch curves: a powerful tool for fisheries research in the Tropics (part 2)
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.
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 ...
An objective method for determining fish growth from length-frequency data
Type: Journal Article
A computing procedure was devised, to determine fish growth, that traces through a series of length frequencysamples sequentially arranged in time, a multitude of growth curves, and then selects the single curve which best ...
On improving operation and use of the elefan programs. part 1, avoiding "drift" of K towards low values
Type: Journal Article
The article proposes improvements for the ELEFAN programs describing how they may be used for optimum output, considering the von Bertalanffy growth equation and the K parameter.
A method for estimating the parameters of a seasonally oscillating growth curve from growth increment data
Type: Journal Article
A linearized version of the Appeldoorn model of the von Bertalanffy growth function is presented for the estimationof parameters of seasonal growth oscillation.
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.
ICLARM's activities in tropical stock assessment: 1979-1984, and beyond
Type: Journal Article
In March 1977, shortly after ICLARM commenced in Manila, its Program Advisory Committee formulated the guiding principles for the Resource Development and Management Program, which is one of the four program areas of ICLARM ...
On the interrelationships between naturual mortality, growth parameters, and mean environmental temperature in 175 fish stocks
Type: Journal Article
A compilation of values for the exponential coefficient of natural mortality (M) is given for 175 different stocks of fish distributed in 84 species, both freshwater and marine, and ranging from polar to tropical waters.
