One another dolphinfish and you can wahoo end up in the newest types state-of-the-art regarding Pelagic Government Equipment Species into West Pacific Local Fishery Administration Council (NMFS, 2001), in which it show a significant component of the commercial landings. Weight-size relationship are also useful for changing metrics inside mark and you can recapture studies and in databases without sometimes metric, as well as can be used to indicate body condition or robustness out of seafood when you look at the a stock (Le Cren, 1951). This research towards dolphinfish and you may wahoo arrived from the Honolulu fish auction throughout 1988-89 relates to W-L predictor variables based on a large number of dimensions coating an extensive size variety.
Oxenford and you may Hunte (1986b) plotted and you can aesthetically opposed the fresh W-L relationships out of dolphinfish off Vermont (Rose and you may Hassler, 1968), Florida (Beardsley, 1967), and you can Barbados (the studies) and found absolutely nothing difference between the new W-L relationships of those towns and cities from the western and you can central Atlantic
Male dolphinfish achieve larger sizes than females. The largest male during the sampling period measured 149 cm, whereas the largest female measured 137 cm. In the initial data examination consisting of 2,495 paired measurements, 13 observations were identified as outliers and deleted from all further analyses. Using data trimmed to a range of 65-137 cm FL, the differences in W-L parameters based on sex for dolphinfish were both significant (coefficient: p <0.01 and exponent: p <0.01; Table 1). Females and males were separately grouped by month of landing; data were trimmed to only include fish in the 90-135 cm FL range, and then analyzed by GLM. Other than March and April, most months covered about 90% or more of the trimmed length range. Month as a categorical factor was significant for both females (p < 0.05; Table 2) and males (p < 0.01; Table 3).
Previous studies have dealt temporarily which have intimate dimorphism from dolphinfish. Some features plotted brand new W-L dating alone for men and lady (Beardsley, 1967; Rose and you may Hassler, 1968; Chatterji and you will Ansari, 1985; and you may Oxenford and you may Hunte, 1986b) otherwise provided independent equations for males and people (Lasso and you may Zapata, 1999; Massuti mais aussi al., 1999) without taking an analytical excuse to your break up. Wang (1979) tabulated the newest suggest W-L individually for men and you may female. Schuck (1951) and Beardsley (1967) merely mentioned that brand new mean W-L for males try greater than women. This research statistically checked-out the difference regarding the W-L coefficients regarding female and male dolphinfish (Table step one) while the empirical difference between predicted indicate W-L can be looked at for the Shape 5. Bannister (1976) visually opposed plots of land off W-L dating regarding dolphinfish stuck throughout the Mediterranean having people caught off New york on west Atlantic (Flower and you may Hassler, 1968). Projected parameters or any other analytical studies getting journal-linearized W-L relationship from Hawaiian dolphinfish are given thus others normally mathematically evaluate W-L coefficients out of dolphinfish off their portion and especially other places of the Pacific Basin (Dining table 4).
Matsumoto (1967) found 38 wahoo larvae and you can juveniles during the step one,643 examples away from oblique plankton tows built-up throughout the open ocean, therefore a small number of spawning may also are present offshore. Although not, a move to nearshore seas in-may to have spawning regarding the summer would-be similar to the increase in reputation and you may catch cost regarding the nearshore fisheries. A diagnosis today underway away from geographical designs and you will shifting out of higher connect rates areas visited from the Their state-created longline fleet implies that the highest variety parts getting wahoo inside range of the brand new fleet are southwestern of your own islands 12 months round but bequeath northward on coastal finance companies delivered more step 1,200 mi. in summer.
