A preliminary account of the population dynamics of Stolephorus devisi (Engraulidae) at Munda Baitground, Solomon Islands
Type: Journal Article
Estimates of growth parameters for Stolephorus devisi (Engraulidae) at Munda Baitground, Solomon Islands were obtained using the Compleat ELEFAN software. Also, estimates of natural and fishing mortality are presented, ...
Growth, mortality and recruitment of exploited small pelagic fishes in the Gulf of California, Mexico
Type: Journal Article
Preliminary, length-based von Bertalanffy growth parameter estimates for Sardinops caeruleus, Opisthonema libertate, Scomber japonicus, Etrumeus teres, and Engraulis mordax, caught in the pelagic fishery based in Guaymas, ...
International research collaboration in rice-fish research
Type: Journal Article
Growing fish in ricefields could dramatically increase farmers' incomes from rice lands and fish production in Asia. This article describes how collaborative international research can strengthen national research ia ...
Estimating the food consumption of fishes: one step in linking a species with its ecosystem
Type: Journal Article
Details are given of a new software package MAXIMS which may be used to estimate the daily food consumption of fish. The software estimates the feeding times, the rates of ingestion and evacuation and related parameters. ...
An empirical comparison of seasonal growth models
Type: Journal Article
A model for describing the seasonally oscillating growth of fish is presented and compared with the commonly used model of D. Pauly and G. Gaschutz (PG). The new model produces results similar to those obtained from teh ...
Interrelationships between swimming speed, caudal fin aspect ratio and body length of fishes
Type: Journal Article
The aspect ratio of the caudal fin of 63 fish species was measured. Swimming speeds for these species, representing 129 cases, were obtained from the literature for various fish sizes and speeds, i.e. "minimum speed" for ...
Estimating natural mortality of Kuwait's Penaeus semisulcatus using a new tag-recapture data analysis method
Type: Journal Article
A novel method was used to estimate natural mortality (M) of Kuwaiti Penaeus semisulcatus using tagging data. The new M estimator is based on two tagging experiments with similar products of initial survival after tagging ...
Can we use traditional length-based fish stock assessment when growth is seasonal?
Type: Journal Article
Based on simulated catch data, this contribution shows that standard length-converted catch curves cannot be used for accurately estimating total mortality when growth oscillates seasonally. Some implications for length-based ...
Population dynamics of Metapenaeus ensis (Penaeidae) in the Gulf of Papua, Papua New Guinea
Type: Journal Article
Growth, total mortality and seasonality of recruitment of male Metapenaeus ensis (Penaeidae) were determined based on length-frequency data (n = 9007) collected in 1988 in the Gulf of Papua, Papua New Guinea.
A note on the inverse function of the von Bertalanffy growth function
Type: Journal Article
Parameter estimates of the von Bertalanffy growth function (VBGF) and its inverse function, based on length-at-age and age-at-length data for Tilapia rendalli (Cichlidae) and Salmo trutta (Salmonidae) were derived using a ...
