Nonlinear W-L and you will L-W dating have been fitted having male and female dolphinfish (Fig
Nonlinear W-L and you will L-W matchmaking that have sexes pooled (Dining table 10; Fig
Just after finishing theory investigations to have dolpinfish, left analyses used the untrimmed analysis. 1-4; Dining table 4), and you can a beneficial L-W connection with sexes pooled is offered for programs where intercourse is actually not available (Fig. 5; Table cuatro). Log-linearized W-L dating for women and you will males was basically and suitable to possess analysis having blogged studies which used which model (Desk cuatro). Nonlinear W-L relationships had been determined on their own for women and you may males for every of eleven-few days groups by using the untrimmed study (Dining tables 5 and you will 6).
To look at transform off standing otherwise pounds in detail over time, month-to-month mean predict loads making use of their important mistake rates have been plotted for females at the site lengths out-of 80 cm, BBW dating sites one hundred cm, 115 cm, and you will 125 cm; and for men within resource lengths of 105 cm, 120 cm, and you will 135 cm Fl (Fig. 6, eight, respectively). Site lengths to own male dolphinfish have been three just as spaced lengths into the the latest observed monthly duration assortment. Reference lengths having girls dolphinfish was basically chosen in which specimens was in fact acceptably within monthly examples. Just for the April (88 cm Fl) and July (83 cm Florida) have been weights for women within 80 cm Florida forecast not in the minimal noticed duration on month. The most differences in monthly predicted imply weights for ladies was indeed fourteen.9% on 80 cm Fl; nine.7% during the one hundred cm Fl; 6.5% at 115 cm Florida; and you will eight.8% in the 125 cm Florida for women. Certainly one of boys, maximum variations in monthly forecast indicate loads was indeed several.5% in the 105 cm Fl; 10.6% in the 120 cm Fl; and you may ten.5% in the 135 cm Fl. There can be a variety of evidence of improved condition in April and you will Will get, and you can diminished standing some time in the summertime. The info are quite effective regarding one or two oscillations annually, peaking into the Oct as well as in April-May and declining 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 = 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 was reduced in the March or March and you will highest in Sep or Oct both for genders as well as site systems
Immediately following doing theory assessment, further analyses made use of untrimmed analysis. Month-to-month nonlinear W-L dating was indeed determined (Desk 9). 8, 9) and a record-linearized W-L dating had been also suitable (Table ten). Month-to-month predicted imply loads in the 120, 135, and you can 150 cm site Florida was in fact plotted in order to show the newest variability out-of condition over the season having wahoo (Fig. 10). Resource lengths had been around three just as spaced lengths really on the noticed duration assortment, except for July if premier fish is measured at 146 cm Florida. The condition of wahoo is large in-may and you may low in July or August for everybody resource versions. The difference for the monthly predict suggest loads within large and you may reduced status have been 7.5% within 120 cm Florida, 8.0% at the 135 cm Fl, and 8.7% during the 150 cm Florida. In place of dolphinfish, there is certainly no idea in excess of you to definitely duration annually.
