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 ...
