Length-weight relationships of soft-bottom demersal fishes from Jalisco and Colima states, Mexico
Type: Journal Article
The parameters a and b of the length-weight relationship of the form W=aL super(b) were estimated for 24 species of soft bottom demersal fishes caught on the continental shelf off Jalisco and Colima states, Mexico. The ...
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. ...
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 ...
Growth, mortality and recruitment of Decapterus kurroides in Davao Gulf, Philippines
Type: Journal Article
The ringnet fishery off Davao, southern Philippines, is briefly described. The major species (36%) in the catch is Decapterus kurroides (Pisces, Carangidae), whose growth parameters and mortality rates (natural and fishing) ...
Some population parameters of commercially-important fishes in the Philippines
Type: Book
The estimates of the von Bertalanffy Growth Function (VBGF) parameters and mortality parameters (Z and M) for some of the commercially-important species caught in the Philippine waters are presented using the FAO-ICLARM ...
Length-weight relationship of fishes and cephalopods from the Balearic Islands (Western Mediterranean)
Type: Journal Article
Length-weight relationship (LWR) parameters of 72 species of fishes and 15 species of cephalopods caught in the Balearic Islands demersal fishery are reported. This is the first compilation of LWR for these groups in the ...
Length-weight relationship of fishes caught in the Itaipu Reservoir, Parana, Brazil
Type: Journal Article
Parameters and related statistics of the length-weight relationship of the form W=aL super(b) are presented for 72 species of fish caught in the area of the Itaipu Reservoir in Parana, Brazil. The b values varied between ...
A biochemical laboratory manual for species characterization of some tilapiine fishes
Type: Brief
This publication is both a manual for the biochemical analysis of several tissues of tilapias and an empirical demonstration of the methods for several species. Given the great and growing importance of tilapia in aquaculture ...
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 ...
Evaluating mortality using length-frequency data when growth parameters are poorly known
Type: Journal Article
A method is presented through which the total mortality undergone by several fish stocks of the same species can be compared when growth parameters are poorly known or unknown. Whereas the estimate of Z obtained via the ...
