Vital statistics of marine fishes of Vanuatu
Type: Journal Article
Vital statistics are presented for 38 marine species of Vanuatu based on previous studies conducted in the area, with parameters describing growth (6 species, 13 sets of parameters), mortality (estimates of M for 6 species), ...
Empirical equations for the estimation of natural mortality in Mediterranean teleosts
Type: Journal Article
Empirical relationships were established linking estimates of the instantaneous rate of natural mortality (M), the von Bertalanffy growth parameters, L sub( infinity ) (or W sub( infinity )) and K, and annual mean water ...
Small fishes as a resource in rural Bangladesh
Type: Journal Article
The role of small fishes in the diet of the rural poor in Bangladesh is described. Basic statistics (maximum size reached, length-weight relationships and prices) are presented for 42 species, belonging to 10 families and ...
The capture and culture of postlarval coral reef fish: potential for new artisanal fisheries
Type: Journal Article
This article summarises the reasons why the removal of postlarval coral reef fish should be sustainable and identify those conditions that may require restrictions to fishing for postlarvae. The authors also outline why ...
A program for the identification of the pelagic eggs of Black Sea fishes
Type: Journal Article
A computer program was developed for the identification of the teleost fish eggs that may be found in the pelagic zone of the Black Sea. The program identifies eggs of 70 species, using up to 28 descriptive characters, and ...
Growth and mortality of spangled emperor Lethrinus nebulosus in Fiji
Type: Journal Article
The parameter L8 and K of the von Bertalanffy growth equation were estimated from length-frequency data of teh spangled emperor Lethrinus nebulosus (Fam. Lethrinidae) caught in the Central and Western Divisions, Fiji. These ...
A program for constructing length-converted growth curves when growth is seasonal
Type: Journal Article
Following Sparre's (1990) demonstration that length-converted catch curves overestimate total mortality when growth is seasonal, Pauly (1990) presented a method for constructing length-converted growth curves that allow ...
The accuracy of some length-based methods for fish population studies
Type: Report
Monte-Carlo simulations of fish populations with different biological characteristics were generated to test the accuracy of some recent methods for the assessment of growth in fishes on the basis of length data. ...
Ecological computer programs: the importance of being friendly
Type: Journal Article
A discussion is presented on the topic of statistical data analysis in the field of ecology, emphasizing the importance of computer programmes being user friendly for the ecologist. Particular reference is given to TWINSPAN, ...
Length-weight relationship of fishes from a seagrass meadow in Negros Oriental, Philippines
Type: Journal Article
The parameters a and b of the length-weight relationship of the form W=aL super(b) were estimated for 13 fish species sampled in a seagrass meadow in Negros Oriental, Philippines. Also, to facilitate conversions, the ...
