From the Indian Water, Chatterji and you can Ansari (1985) checked sexual dimorphism from inside the W-L dating for east African dolphinfish

Regarding the Their state commercial longline, troll, and you may handline fisheries having highly migratory pelagic kinds, each other dolphinfish (mahimahi), Coryphaena hippurus, and you may wahoo (ono), Acanthocybium solandri, is by the way trapped and generally are away from secondary pros in order to tunas, Scombridae, and you can billfishes, Istiophoridae. Their relative wealth, sector consult, and you will seemingly faster proportions sign up for its secondary character.

Since interest of fishery management broadens to include a wide directory of variety into the aquatic ecosystems, a growing you desire is available to check on catch studies into the variety trapped incidentally. Weight-on-length (W-L) and you may duration-on-weight (L-W) matchmaking are necessary to convert on-water size specifications so you can loads, ine designs when you look at the seafood status which can promote information towards reproductive lifestyle records and you can ecology.

Of many W-L predictors have been wrote for dolphinfish; these types of relationship was in fact discussed about Mediterranean sea (Bannister, 1976; Massuti ainsi que al., 1999); east tropical Atlantic (Castro mais aussi al., 1999), west exotic Atlantic while the Carribean (Oxenford and Hunte, 1986b; Oxenford, 1999), brand new Straits regarding Fl (Beardsley, 1967), Gulf coast of florida therefore the Gulf Stream (Gibbs and you may Collette, 1959), and you may Vermont oceans (Schuck, 1951; Rose and you will Hassler, 1968).

Where lots of W-L predictors getting dolphinfish was explained in the world, simply about three published records (Iversen and Yoshida, 1957; Beardsley and you will Richards, 1970; Santana, et al. (3)) and you may an excellent PhD. thesis (Hogan, 1976) features discussed W-L dating to own wahoo. A lately blogged comment to the wahoo regarding the western Main Atlantic area because of the Oxenford mais aussi al. (2003) said around three most other degree for the a table of numerous morphometric dating. Beardsley and you may Richards (1970) considering a beneficial W-L dating having wahoo of the southern part of Fl playing with investigation obtained from taxi-dermists. Santana et al. (3) demonstrated new W-L relationship out-of wahoo stuck in the Canary Isles regarding east Atlantic Sea. On the Pacific Water, Iverson and you will Yoshida (1957) provided a good W-L matchmaking to own wahoo trapped inside the Line Islands in the equatorial main Pacific.
