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 ...
Length-weight relationships of marine fishes from the central Brazilian coast
Type: Journal Article
Parameters of the length-weight relationship are presented for 85 fish species from the marine and estuarine regions of the central Brazilian coast (latitude 13° to 23° S). Three different methods were used. A non-linear ...
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 ...
