There has not yet come a thorough research with the W-L relationships to own wahoo trapped around the Hawaiian islands

As the attract out of fishery management broadens to include a bigger range of variety in the aquatic ecosystems, an ever growing you prefer is available to test connect analysis toward kinds trapped by the way. Weight-on-size (W-L) and you may duration-on-lbs (L-W) dating are needed to move on-sea length dimensions to loads, ine patterns into the seafood position that can offer information for the reproductive lives record and ecology.

Of a lot W-L predictors was in fact had written to possess dolphinfish; this type of matchmaking was indeed demonstrated regarding Mediterranean and beyond (Bannister, 1976; Massuti et al., 1999); east tropical Atlantic (Castro mais aussi al., 1999), western tropical Atlantic additionally the Carribean (Oxenford and you may Hunte, 1986b; Oxenford, 1999), brand new Straits of Fl (Beardsley, 1967), Gulf of mexico together with Gulf coast of florida Load (Gibbs and you will Collette, 1959), and you may North carolina seas (Schuck, 1951; Rose and you can Hassler, 1968).

Where lots of W-L predictors to own dolphinfish had been revealed worldwide, merely about three authored account (Iversen and Yoshida, 1957; Beardsley and you may Richards, 1970; Santana, et al. (3)) and you may a PhD. thesis (Hogan, 1976) features revealed W-L relationship having wahoo. A not too long Over 50 dating review ago composed comment on the wahoo about west Main Atlantic part by the Oxenford et al. (2003) mentioned around three most other training for the a dining table of various morphometric relationships. Beardsley and you may Richards (1970) considering a beneficial W-L dating to possess wahoo from the southern area of Fl having fun with research taken from taxi-dermists. Santana et al. (3) explained the W-L matchmaking from wahoo stuck in the Canary Countries on eastern Atlantic Water. In the Pacific Sea, Iverson and you can Yoshida (1957) considering an excellent W-L relationship to own wahoo caught inside the Range Countries on equatorial central Pacific.

Hogarth (1976) discussed an effective W-L dating to have wahoo predicated on data in the sport fishery from the New york shore
