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 ...
Small-scale fisheries of San Miguel Bay, Philippines: biology and stock assessment
Type: Report
The report analyzes the biological aspects of the fisheries of San Miguel Bay representing the results of data collection and analysis over approximately a 2-year period, 1979-81.
A selection of 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 ...
Fisheries resources management in Southeast Asia: why bothers?
Type: Book Chapter
Because, in general, the economies of Southeast Asian countries are "developing", policy-makers generally assume that the fisheries sector also needs to be "developed" through soft loans, tax rebates, construction of ports, ...
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 ...
History and status of the San Miguel Bay fisheries
Type: Book Chapter
This paper reviews the available data on San Miguel Bay fisheries and their history, and contrasts "small-scale" and "trawl" fisheries, each of which land about half of the Bay's total catch of 15000 t / year. On the basis ...

The mode of operation and contents of a custom-made plug-in memory device for Hewlett-Packard HP41CV calculators (or HP41C with Quad Memory Module) are briefly presented. The module contains 15 of the 30 programs for fish ...
Application of information on age and growth of fish to fishery management
Type: Book Chapter
Information on the age and growth of fish is usually related to one or several of the following items: construction of age/length keys for direct use in some assessment models (e.g. Virtual Population Analysis); estimation ...
