Calico phase individuals were observed at both transect sites throughout the study period (Figure 4). OS phase males were observed at both transect sites from , where they increased in frequency over this period (Figure 4). Monthly variations in the proportion of OS phase individuals observed on transects were significantly different than expected at random for both the Intake Pipes site (Pearson chi-square goodness of fit, [chi square] = , df = 7, P < 0.01) and the Pumpernickel Cove site (Pearson chi-square goodness of fit, [chi square] = , df = 7, P < 0.01).
Aforementioned incorporated some one believed to intimately kids
Mean monthly GSI of males (Figure 3) and females (Figure 5) remained low from January to April. GSI values of males and females were lowest in February and December. Monthly variations in male GSI (Kruskal-Wallis, KW = , df = 8, P < 0.01) and female GSI (Kruskal-Wallis, KW = , df = 8, P < 0.01) were significant. Males and females containing visibly ripe gonadal tissue were collected from May to October, and over 93% of adults collected from June to August were visibly ripe. Females with hydrated ovaries were collected from June through September, and the highest frequency of hydrated females occurred in July (Figure 5). The mean GSI of females with hydrated ovaries (5.79%) was significantly higher than the mean GSI of non-hydrated, ripe females (3.56%; unpaired t test, t = 7.78, df = 229, p < 0.01).
Operating-system phase people were present all the time and on a regular basis in both the field findings conducted off , plus the new attentive examination of 2002. Operating-system phase people were maybe not observed in profession observations conducted in late . As no significant difference try found in the monthly frequency of this new Operating-system stage among people gathered away from (Pearson chi-square god from fit, [chi square] = step one.19, df = 2, P = 0.55), investigation out of all the boys obtained out of during this time was pooled for further analysis. Through that period, Operating-system stage men was indeed compiled for hours and you will showed no extreme variations in frequency according to the time frame grabbed (Pearson chi-square god out-of match, [chi-square] = 1.36, df = dos, p = 0.51). More over, the fresh new frequency off Operating system phase males failed to disagree significantly certainly the latest five no. 1 stages of the lunar course (Pearson chi-square, [chi square] = cuatro.forty-five, df = step three, P = 0.22).
Operating-system phase people compiled of ranged in size away from 165 to 386 mm SL, and you can calico phase boys collected during those times several months ranged inside dimensions out of 170 so you can 397 mm SL (Profile 6). The suggest duration of amassed Operating-system phase males ( mm) is rather greater than this new suggest amount of collected calico phase guys ( mm; Mann-Whitney, You = 5455.0, df = 247, P = 0.001). not, so it results wasn't noticed biologically tall, given that adult P. clathratus grow so you're able to lengths of more than 700 mm SL (Like mais aussi al. 1996). The dimensions listing of attentive Os phase people (211 in order to 348 mm SL) try like attentive calico phase people (212 in order to 343 mm SL). Operating system stage some one present in the field varied from inside the projected dimensions away from 2 hundred so you can five-hundred mm SL, when you're calico phase someone noticed varied sizes of a hundred to five hundred mm SL.
The brand new estimated spawning seasons centered on GSI and you can maturity studies showed a cycle similar to the month-to-month regularity out-of built-up Operating-system stage males
The OS phase was present only in ripe males, whereas the calico phase was present in both ripe and unripe males. Sixty-seven percent of ripe males collected during 2001 were OS phase and 33% were https://datingranking.net/local-hookup/topeka/ calico phase. Among males collected from , the GSI range of OS males (0.42% to %) were similar to that of calico phase males (0.17 to %) (Figure 7a). However, the mean GSI of OS males (5.69%) was significantly higher than that of calico phase males (2.88%) collected from (Mann-Whitney, U = , df = 237, P < 0.01) (Figure 7b).
