Weight-on-size (W-L) and length-on-pounds (L-W) matchmaking are necessary to move on-sea size specifications so you’re able to weights, ine designs for the seafood condition that will give wisdom to the reproductive life record and you may environment.
Of numerous W-L predictors was in fact composed getting dolphinfish; this type of relationships have been discussed on Mediterranean sea (Bannister, 1976; Massuti ainsi que al., 1999); east warm Atlantic (Castro ainsi que al., 1999), western exotic Atlantic in addition to Carribean (Oxenford and you may Hunte, 1986b; Oxenford, 1999), this new Straits regarding Fl (Beardsley, 1967), Gulf of mexico additionally the Gulf Stream (Gibbs and you may Collette, 1959), and Vermont waters (Schuck, 1951; Flower and you may Hassler, 1968).

(3) revealed the fresh W-L relationship out of wahoo stuck inside the Canary Isles from the east Atlantic Ocean. On Pacific Ocean, Iverson and you can Yoshida (1957) given an excellent W-L matchmaking to possess wahoo caught in the Range Islands regarding equatorial main Pacific.
Hogarth (1976) described good W-L matchmaking for wahoo centered on research about sport fishery off the North carolina coast
