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 ...
Estimation and comparison of fish growth parameters from pond experiments: a spreadsheet solution
Type: Manual
A method is presented to estimate and compare the growth of fish in pond experiments using a Gulland/Holt plot. The method is implemented as a LOTUS 1-2-3 "spreadsheet" allowing easy data editing and analysis. An example ...
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.
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 ...
The general von Bertalanffy growth function: possible use in the Beverton and Holt model
Type: Journal Article
Using the concept of generalized Von Bertalanffy growth formula developed by Pauly and Gasch? tz, we tried to integrate the basic equation of Beverton and Holt and to check on changes in the quantitative evaluation of ...
Summary of length-frequency data for Philippine small pelagic fishes collected by the DA-BFAR/ICLARM Small Pelagics Management Project (Vols. I II)
Type: Report
The Small Pelagic Management project was established in the Philippines to conduct a review of Philippine small pelagic fisheries and to conduct stock assessment and economic analyses on these fisheries. Growth, mortality ...
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 ...
Preliminary length-based growth parameter estimates of peruvian sardine (Sardinops Sagax Sagax)
Type: Journal Article
Growth parameter estimates of the Peruvian sardine (Sardinops sagax sagax ) were obtained using the ELEFAN I programme to analyze length-frequency data.
Fish mariculture studies in China
Type: Journal Article
The development of marine fish aquaculture in China is discussed; major species cultured include: mullets, tilapias, milkfish, porgies, groupers, flounders and seahorses.
Notes on the assessment of the stocks of small pelagic species on the basis of length frequency analysis and converted catch curves
Type: Journal Article
Difficulties are usually encountered when small pelagic species are to be assessed, using simple classical methods such as the surplus production model. Interannual variations of recruitment and fishing patterns and ...
