Population dynamics of Nemipterus japonicus from the northern Arabian Sea, Pakistan
Type: Journal Article
Catch-per-effort and length-frequency data on threadfin bream Nemipterus japonicus (Nemipteridae) supplied by the staff of the R/V Dr. Fridtjof Nansen, covering the period September 1983 to June 1984, were analyzed using ...
Correction to the Beverton and Holt Z-estimator for truncated catch length-frequency distributions
Type: Journal Article
A method for estimating the instantaneous mortality rate (Z) is presented which was developed from a truncated equation for average length. The model has zero bias at equilibrium, but has no explicit solution for Z so that ...
The biometrics of marine fishes from the Gulf of Aden
Type: Journal Article
The growth parameters (L sub( infinity ), K, t sub(0)), total mortality and length-weight relationships of 23 speciesof fishes studied during a UNESCO-sponsored study of the fish populations of the Gulf of Aden, in the mid-1980s, ...
Growth and feed utilization of Oreochromis niloticus fingerlings fed with diets containing cassava peelings and mango seeds
Type: Journal Article
The results are presented of trials conducted whereby cassava peel and mango seed were fed to Nile tilapia (Oreochromis niloticus ) fingerlings. Findings indicate that these products may successfully be used as part of thediets ...
Molluscicidal compunds of plant origin
Type: Journal Article
There is great impetus among phytochemists to develop molluscicides which are lethal to the snail intermediate hosts of bilharzia. They search for plant-derived, water-soluble compounds that are cheap to isolate, specific ...

Type: Journal Article
Details are given of a simple method for the year-round production of Clarias gariepinus fry in homestead concrete tanks. Procedures involved regarding the induced spawning of the fish, egg hatching and rearing of fingerlings ...
Mollusc and crustacean culture possibilities in Lagos lagoon and the Niger Delta
Type: Journal Article
An examination is made of the possibilities of the development of mollusc and crustacean culture, especially intraditional harvesting areas of the Niger Delta, as a means of accelerating protein self-sufficiency. Scope for ...
Who's working on Mugil culture
Type: Journal Article
The findings are presented of a survey conducted regarding research on Mugil culture; emphasis was given to publications from the tropics and subtropics, particularly from developing regions. The literature search used ...
Preliminary estimates of growth parameters for three commercial bivalve species of Peru (Gari solida, Anlacomya ater and Semele solida)
Type: Journal Article
The parameters of the von Bertalanffy growth equation were estimated, mainly from size-frequency data, for three commercially exploited Peruvian bivalves, Gari solida, Aulacomya ater and Semele solida, collected by divers ...
Simple broodstock management to control indirect selection and inbreeding: Indian carp example
Type: Journal Article
Following a survey of the important traits of Indian carp broodstock at some southern Indian hatcheries, it was found that the broodstock selection was size selective, exerting strong, negative selection of prematuration ...
