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).
The latter included anybody considered sexually 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 stage individuals were expose throughout the day as well as on a good regular basis both in industry findings conducted out of , and also in the fresh attentive examination of 2002. Operating system stage everyone was maybe not present in field findings presented inside the later . Due to the fact no factor are based in the monthly volume out-of the newest Os stage among men built-up of (Pearson chi-rectangular jesus away from fit, [chi square] = step one.19, df = 2, P = 0.55), studies out-of all males amassed out-of during this period had been pooled for further investigation. Through that months, Os phase people had been accumulated from day to night and you can presented no high differences in regularity with regards to the period of time grabbed (Pearson chi-square jesus from match, [chi square] = step one.36, df = dos, p = 0.51). More over, the newest frequency from Operating-system phase males did not disagree notably one of the fresh new five primary phase of one’s lunar years (Pearson chi-square, [chi-square] = 4.forty-five, df = step three, P = 0.22).
Operating system stage males compiled of ranged sizes from 165 in order to 386 mm SL, and you will calico stage people compiled at that moment period varied inside the size regarding 170 in order to 397 mm SL (Contour six). The fresh new indicate length of gathered Operating-system phase males ( mm) is actually somewhat greater than new suggest length of compiled calico stage males ( mm; Mann-Whitney, You = 5455.0, df = 247, P = 0.001). But not, so it impact was not believed naturally tall, once the adult P. clathratus develop so you can lengths greater than 700 mm SL (Love ainsi que al. 1996). The shape variety of captive Operating system stage guys (211 so you can 348 mm SL) is actually like attentive calico phase males (212 to 343 mm SL). Operating system phase some one present in industry varied inside estimated size regarding two hundred in order to five-hundred mm SL, while you are calico phase some body observed ranged sizes regarding one hundred so you’re able to five-hundred mm SL.
Brand new projected spawning 12 months centered on GSI and readiness analysis exhibited a period like the month-to-month regularity off accumulated Operating system stage people
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 calico phase. Among males collected adult hookup sites Sheffield 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).
