Length-weight relationships of select common nearshore Southern California Marine Fishes.(Research Notes)
Dec 01, 2008; ... Growth dynamics of marine fish is often critical for fisheries analysis. Frequently only lengths are measured during ecological surveys, occasionally with aggregate weights by species (Allen and Herbinson 1990; Pondella and Allen 2000; Allen et al. 2002). This information often allows for ...
