Estimating the maximum sustainable yield of bonito (Sarda chiliensis, Scombridae) of northern Chile from monthly catch data
Type: Journal Article
Monthly catch data of bonito Sarda chiliensis from northern Chile, from 1976 to 1989, were used to obtain a series of estimates of the "Z-G" parameter (i.e., total mortality minus the growth coefficient in weight). This ...
Comparative growth performance of jack mackerels of the genus Trachurus with emphasis on T. symmetricus murphyi in Chile
Type: Journal Article
This contribution presents von Bertalanffy growth parameter estimates for species/stocks of jack mackerels of the genus Trachurus from around the world, and compares them with growth parameters for T. symmetricus murphyi ...
Maximo rendimiento sostenible de la pesqueria comercial en el Departamento de Loreto, Peru
Type: Journal Article
Catch and effort data from the river fisheries of the Peruvian part of Amazonia are presented, and used to fit a Schaefer-type surplus production model. This suggests that present effort is in excess of what is required ...
Population parameters of 'corvina' (Plagioscion squamosissimus) in the Barra Bonita Reservoir, Brazil
Type: Journal Article
Estimates for the growth parameters (L sub( infinity ) and K) mortality coefficients (Z,M and F) and exploitation rate (E) for the sciaenid Plagioscion squamosissimus are presented. The following results were obtained: 1) ...
Population parameters of Penaeus californiensis in the Gulf of Guayaquil, Ecuador
Type: Journal Article
The growth, mortality, and recruitment pattern of Penaeus californiensis were investigated using tail length (TL)-frequency data obtained from the Gulf of Guayaquil shrimp population. Computer-based methods of tail-frequency ...
Life cycle and biological parameters of several Brazilian Amazon fish species
Type: Journal Article
This contribution summarizes knowledge on the biology (population dynamics, reproduction, ecology) of 25 fish species from the Lower Amazon, Brazil, based on data from a Brazilian-German field project (IARA) and a review ...
Exploitation of the dolphin-fish Coryphaena hippurus L. off Ecuador: analysis by length-based virtual population analysis
Type: Journal Article
Dolphin-fish Coryphaena hippurus in the east Central Pacific are principally exploited by Ecuador. A length-based virtual population analysis of this fishery was sensitive to assumed values of growth parameters in ...
