Nonlinear W-L and you will L-W relationships which have sexes pooled (Desk 10; Fig
Once finishing hypothesis research for dolpinfish, remaining analyses utilized the untrimmed research. 1-4; Table cuatro), and good L-W experience of men and women pooled is provided to own programs in which sex is not available (Fig. 5; Table cuatro). Log-linearized W-L relationship for females and you can boys were and additionally installing getting assessment that have penned knowledge that used which model (Dining table cuatro). Nonlinear W-L dating was basically computed on their own for women and https://datingranking.net/asian-dating/ you will males for each of one’s 11-week teams by using the untrimmed study (Tables 5 and you will six).
To look at alter out of standing or pounds in more detail through the years, monthly suggest forecast weights due to their practical error prices was in fact plotted for women at reference lengths out of 80 cm, 100 cm, 115 cm, and you will 125 cm; as well as people on resource lengths of 105 cm, 120 cm, and you will 135 cm Florida (Fig. six, seven, respectively). Resource lengths to have men dolphinfish was indeed three similarly separated lengths inside the newest observed month-to-month size variety. Source lengths having people dolphinfish was indeed chosen in which specimens was effectively found in month-to-month examples. Just inside the April (88 cm Florida) and you will July (83 cm Florida) were weights for women at 80 cm Fl forecast outside the lowest noticed length on the month. The most differences in monthly predict imply weights for females was 14.9% during the 80 cm Fl; 9.7% from the 100 cm Florida; 6.5% from the 115 cm Fl; and you will 7.8% at the 125 cm Florida for women. Certainly guys, the maximum variations in month-to-month forecast indicate loads was 12.5% on 105 cm Florida; 10.6% at 120 cm Fl; and you may 10.5% in the 135 cm Florida. There clearly was a variety of proof of enhanced condition in April and you can Get, and you can reduced condition a bit during summer. The info is actually a bit suggestive out of a few oscillations a-year, peaking in the October plus in April-Could possibly get and you can declining in summer and also in November.
Since the sex of wahoo was unobtainable at the fish auction, length-weight-sex data collected on research cruises were used to examine sexual dimorphism. Female wahoo measurements ranged from 84.5 to 157.5 cm FL (n = 112); males ranged from 79.1 to 148.7 cm FL (n = 59). Cursory examination of both cruise and auction measurements indicated four outliers for data collected at the auction. The latter were deleted. With lengths trimmed to include only 110-145 cm FL, the cruise-sampled fish indicated that sex had no significant effect on the wahoo W-L parameters (coefficient: p = 0.18, exponent: p = 0.17, n = 144; Table 7). Wahoo L-W data collected at the auction were trimmed to include fish in the 108-160 cm FL range. Except for January and July, most months covered about 90% or more of the trimmed range. The effect of month as a categorical factor on W-L coefficients was significant (p < 0.01; Table 8).
The condition of dolphinfish try lower in February otherwise February and you will highest in Sep or October for both sexes and all sorts of site sizes
Once completing hypothesis evaluation, further analyses used untrimmed data. Monthly nonlinear W-L dating was basically computed (Dining table nine). 8, 9) and a record-linearized W-L matchmaking was as well as fitting (Table ten). Monthly forecast imply weights during the 120, 135, and you may 150 cm site Fl was in fact plotted so you’re able to instruct the variability from standing along the 12 months to possess wahoo (Fig. 10). Site lengths were three equally spread lengths better throughout the noticed size assortment, apart from July if the premier fish is actually measured from the 146 cm Florida. The state of wahoo are highest in may and you may lower inside July or August for all resource systems. The difference in the month-to-month predicted indicate weights within higher and you can lowest reputation was indeed 7.5% at 120 cm Fl, 8.0% within 135 cm Fl, and 8.7% from the 150 cm Florida. Instead of dolphinfish, there clearly was zero tip greater than one to stage per year.
