Application to shrimp stocks of objective meathods for the estimation of growth, mortality and recruitment-related parameters from length-frequency data (ELEFAN I and II)
Type: Book Chapter
This paper presents applications to several shrimp stocks of a new, computer-based set of methods for the detailed analysis of length-frequency data. These applications include the objective estimation of growth parameters, ...
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) ...
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.
Some simple methods for the assessment of tropical fish stocks
Type: Report
This selection of methods is based on lecture notes used at a FAO/DANIDA training course held in Mombasa, Kenya, in May-June 1980. The methods presented are: regression and correlation, estimation of growth parameters from ...
Length-based methods in fisheries research
Type: Conference Proceedings
This proceedings include the twenty-two papers which were originally presented in in a conference on The Theory and Application of Length-Based Stock Assessment Methods which took place on 11-16 February 1985 at the Istituto ...
ICLARM's Resource Development and Management Program: the Tropical Stock Assessment Research Project
Type: Journal Article
The project was conceived to identify and overcome the major constraints preventing the development of stock assessment techniques appropriate to tropical stocks. These constraints are listed and the project's programme of ...
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, ...
Zur Fischereibiologie tropischer Nutztiere: Eine Bestandsaufnahme von Konzepten und Methoden
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 ...
