Nonlinear W-L and you can L-W matchmaking with men and women pooled (Dining table ten; Fig
Once completing theory testing getting dolpinfish, kept analyses utilized the untrimmed studies. 1-4; Dining table cuatro), and an effective L-W connection with sexes pooled is provided getting apps where gender is actually unavailable (Fig. 5; Table cuatro). Log-linearized W-L relationship for women and you may boys was in fact plus fitted to own testing which have published degree which used this model (Desk 4). Nonlinear W-L matchmaking were computed alone for females and males each of the eleven-day groups utilizing the untrimmed study (Tables 5 and you will six).
To look at alter away from status or pounds thoroughly over time, monthly suggest predicted loads due to their basic mistake quotes have been plotted for ladies during the resource lengths away from 80 cm, a hundred cm, 115 cm, and you will 125 cm; as well as for boys from the reference lengths out of 105 cm, 120 cm, and you will 135 cm Fl (Fig. 6, eight, respectively). Resource lengths getting male dolphinfish was indeed about three just as spread lengths https://datingranking.net/american-dating/ in the brand new noticed monthly duration variety. Resource lengths getting women dolphinfish was in fact picked where specimens was indeed acceptably present in month-to-month trials. Just in the April (88 cm Florida) and you may July (83 cm Fl) was indeed weights for ladies from the 80 cm Fl predict not in the minimal observed length on day. The most differences in monthly forecast indicate loads for females was 14.9% in the 80 cm Florida; nine.7% at the one hundred cm Fl; 6.5% at 115 cm Fl; and you can 7.8% at the 125 cm Florida for women. One of men, the maximum variations in month-to-month forecast suggest weights had been a dozen.5% in the 105 cm Florida; 10.6% from the 120 cm Fl; and you will ten.5% from the 135 cm Florida. There is certainly a variety of proof increased condition in April and you may Could possibly get, and you can decreased status sometime during the summer. The content is a little effective from one or two vibrations a year, peaking within the Oct as well as in April-Will get and you may decreasing during the summer and 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 state of dolphinfish is lowest from inside the February otherwise February and you will higher during the Sep otherwise October for both sexes as well as resource systems
Just after completing theory assessment, subsequent analyses made use of untrimmed data. Monthly nonlinear W-L dating have been determined (Desk 9). 8, 9) and you will a journal-linearized W-L relationships had been also installing (Table ten). Monthly forecast indicate loads within 120, 135, and 150 cm resource Florida was indeed plotted to help you show the brand new variability off condition across the year to own wahoo (Fig. 10). Site lengths was indeed three equally separated lengths better on the observed duration variety, apart from July when the largest fish try counted within 146 cm Florida. The state of wahoo is highest in may and you may reduced in the July or August for everyone resource versions. The difference when you look at the month-to-month forecast suggest weights involving the high and you can lowest condition was in fact eight.5% from the 120 cm Fl, 8.0% from the 135 cm Fl, and you may 8.7% on 150 cm Fl. As opposed to dolphinfish, there was no tip of more than one stage annually.
