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 ...
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.
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.
Announcing the release of version 1.1 of the compleat ELEFAN software package
Type: Journal Article
Version 1.1 of the Compleat ELEFAN program package of length-based fish stock assessment studies is presented, indicating the differences with version 1.0 and describing minimum hardware requirements.
ICLARM's Resource Development and Management Program: the Tropical Stock Assessment Research Project
Type: Journal Article

Die Notwendigkeit, adaquate Methoden far die Untersuchung der Dynamik von tropischen Fischereiressourcen bewuBt zu entwickeln, ergibt sich (a) aus ihrer enormen Bedeutung Kir die Ernahrung und als Einkommensquelle von ...
Fish stock assessment in coral reefs: notes on the state of the art
Type: Journal Article
Coral reefs may produce as much as 10% of the annual world fish catch. Yet, very little investigation has been done on the biology of coral reef fishes, so that we know little about their growth rates and mortalities, vital ...
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 ...
