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 ...
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 ...
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 ...
Length-weight relationships of fishes from tributaries of the Volta River, Ghana: Part II and Conclusion
Type: Journal Article
Slopes and intercepts of length-weight relationships obtained from 37 populations from the rivers Oti, Pru and Black Volta in Ghana were compared using a one way analysis of covariance with fixed effects. Although no ...
Length-weight relationships of fishes from tributaries of the Volta River, Ghana Part 1: Analysis of pooled data sets
Type: Journal Article
The parameters a and b of length-weight relationships of the form W = a L super(b) were estimated for 45 fish species sampled in the Oti, Pru and Black Volta rivers, Ghana. Also, the slope and intercepts of regressional ...
On length-weight relationships. Part II: Computing mean weights from length statistics
Type: Journal Article
Assuming a known length-weight relationship, the formula for calculating the mean weight from grouped length statistics is recapitulated. Then a simple analytical method for calculating mean weight from basic length ...
Growth, mortality and recruitment of Omani abalone (Haliotis mariae)
Type: Journal Article
Historical length-frequency data of Oman abalone (Haliotis mariae) from two areas (Sadh and Hadbin) of the Dhofar coast of the Sultanate of Oman were used to estimate growth parameters by nonlinear least square fitting. ...
Quantitative analysis of published data on the growth, metabolism, food consumption, and related features of the red-bellied piranha, Serrasalmus nattereri (Characidae)
Type: Journal Article
A tentative set of growth parameters of the von Bertalanffy growth equation were estimated for the red-bellied piranha, Serrasalmus nattereri, a common characid of the Amazonas and adjacent floodplains, based on length-frequency ...
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 ...
