Both dolphinfish and you can wahoo end up in new variety cutting-edge away from Pelagic Government Equipment Variety on Western Pacific Regional Fishery Management Council (NMFS, 2001), in which they depict an essential element of the economical landings. Weight-size matchmaking are also useful for changing metrics in mark and you can recapture studies and in database without often metric, in addition they can be used to mean human body position otherwise robustness from seafood from inside the a stock (Le Cren, 1951). This study towards the dolphinfish and you will wahoo arrived on Honolulu fish market throughout 1988-89 relates to W-L predictor variables centered on 1000s of proportions level a broad size assortment.

Oxenford and you will Hunte (1986b) plotted and you can aesthetically compared the fresh new W-L matchmaking out of dolphinfish of New york (Rose and you will Hassler, 1968), Fl (Beardsley, 1967), and you will Barbados (their data) and found nothing difference in the fresh W-L dating of the towns regarding west and you may main 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 research has worked temporarily having intimate dimorphism off dolphinfish. Particular have plotted new W-L dating by themselves for males and you can females (Beardsley, 1967; Flower and you will Hassler, 1968; Chatterji and Ansari, 1985; and you can Oxenford and Hunte, 1986b) or considering separate equations for males and you may females (Lasso and you can Zapata, 1999; Massuti ainsi que al., 1999) as opposed to bringing a mathematical justification towards the break up. Wang (1979) tabulated this new indicate W-L by themselves for men and you may lady. Schuck (1951) and you will Beardsley (1967) just said that the newest suggest W-L for men try greater than people. This study mathematically looked at the difference on W-L coefficients away from men and women dolphinfish (Desk 1) in addition to empirical difference between predicted imply W-L can be viewed inside Shape 5. Bannister (1976) aesthetically compared plots away from W-L relationship out of dolphinfish stuck in the Mediterranean with the individuals stuck off New york in the west Atlantic (Rose and Hassler, 1968). Projected details or other analytical analysis for log-linearized W-L relationship from Hawaiian dolphinfish are provided therefore anyone else normally mathematically examine W-L coefficients out-of dolphinfish off their portion and especially other places of Pacific Basin (Desk cuatro).

Matsumoto (1967) located 38 wahoo larvae and you may juveniles into the step 1,643 samples off oblique plankton tows accumulated on open water, thus a restricted amount of spawning might also are present offshore. However, a proceed to nearshore waters in may to have spawning on june is similar to the rise in updates and you will connect prices from the nearshore fisheries. An analysis now started from geographic activities and moving forward off high catch speed portion went to by the Hawaii-built longline collection suggests that the greatest abundance elements for wahoo in this listing of the fresh fleet is actually southwest of your own isles season bullet however, give northward for the coastal finance companies distributed more than 1,2 hundred mi. in summer.
