Nonlinear W-L and L-W relationship with sexes pooled (Desk 10; Fig
After finishing theory assessment to have dolpinfish, kept analyses utilized the untrimmed investigation. 1-4; Desk cuatro), and a L-W experience of men and women pooled emerges having programs in which sex is actually not available (Fig. 5; Desk cuatro). Log-linearized W-L dating for ladies and boys was in fact in addition to fitted for research having had written education which used so it design (Table cuatro). Nonlinear W-L relationships was basically calculated individually for females and you may males each of your own eleven-times communities by using the untrimmed study (Tables 5 and you may 6).
To look at changes out of status or lbs thoroughly over the years, month-to-month imply predicted loads through its fundamental mistake rates was in fact plotted for ladies during the resource lengths from 80 cm, 100 cm, 115 cm, and 125 cm; and men on resource lengths regarding 105 cm, 120 cm, and you can 135 cm Fl (Fig. 6, seven, respectively). Reference lengths to possess men dolphinfish was basically three equally spread lengths into the the fresh noticed month-to-month size variety. Resource lengths having people dolphinfish was indeed picked in which specimens was in fact adequately contained in month-to-month examples. Only in April (88 cm Fl) and you can July (83 cm Fl) had been weights for women in the 80 cm Fl forecast not in the minimal noticed size towards times. The utmost variations in monthly predict mean weights for females were 14.9% within 80 cm Fl; 9.7% at one hundred cm Fl; six.5% from the 115 cm Fl; and you can seven.8% at 125 cm Florida for women. Certainly boys, the utmost variations in month-to-month forecast suggest loads was a dozen.5% within 105 cm Florida; 10.6% at 120 cm Fl; and 10.5% at the 135 cm Fl. You will find also some proof of enhanced symptom in April and you may Will get, and decreased condition a little while in the summer. The info are somewhat suggestive regarding a few vibration a-year, peaking from inside the Oct and in April-Could possibly get and you can decreasing during the summer as well as 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 = Adventure dating service 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 reasonable into the February otherwise March and highest when you look at the September otherwise Oct for genders and all source systems
Once finishing hypothesis testing, next analyses utilized untrimmed research. Monthly nonlinear W-L dating was basically calculated (Desk nine). 8, 9) and you may a record-linearized W-L dating was indeed and additionally fitted (Dining table 10). Month-to-month forecast imply weights within 120, 135, and you will 150 cm site Florida was plotted in order to illustrate new variability from condition along the 12 months to possess wahoo (Fig. 10). Reference lengths was three equally spread lengths really throughout the seen length variety, apart from July when the biggest fish try mentioned at the 146 cm Fl. The condition of wahoo try higher in may and you can lower in July otherwise August for all resource sizes. The difference inside month-to-month predicted imply weights between your high and you may reasonable position was in fact eight.5% during the 120 cm Florida, 8.0% within 135 cm Fl, and 8.7% during the 150 cm Florida. In the place of dolphinfish, there’s no suggestion of greater than you to stage annually.
