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 ...
On traditional knowledge, fish and databases: a call for contributions
Type: Journal Article
Diet composition and trophic levels of marine mammals
Type: Journal Article
Standardized diet compositions were derived for 97 species of marine mammals from published accounts of stomach contents as well as from morphological, behavioural and other information. Diet was apportioned among eight ...
Announcing the release of FishBase 96
Type: Journal Article
FishBase is a computerized encyclopedia of fishes developed at International Center for Living Aquatic Resources Management (ICLARM) with the support of the European Commission and in collaboration with a large number of ...
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 ...
Growth of the checkered puffer Sphoeroides testudineus: postscript to papers by Target and Pauly Ingles
Type: Journal Article
J. Ingles and D. Pauly presented at the Fourth International Coral Reef Symposium a seasonally oscillating growth curve for the puffer Sphoeroides testudineus (Tetraodontidae), based on length-frequency data collected in ...
Measuring ecological stress: variations on a theme by R.M. Warwick
Type: Journal Article
Two new indices are presented which reflect quantitatively the changes to be expected in an ecological community under stress, as previously described by R. M. Warwick. The indices summarize information which he presented ...
Simulation of the effects of oxygen on food consumption and growth of Nile tilapia, Oreochromis niloticus (L.)
Type: Journal Article
Fish need oxygen for aerobic generation of energy for body maintenance, locomotion, feeding and biosynthesis. The rate of oxygen uptake of most fish is limited by diffusion through the gills, and gill surface area grows ...
