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 provided somebody said to sexually younger
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 citizens were introduce all the time as well as on good consistent basis in both industry findings held regarding , and also in the newest attentive examination of 2002. Os phase everyone was not present in occupation findings presented during the later . Since no significant difference is found in the month-to-month volume off the fresh new Operating system stage certainly one of males compiled regarding (Pearson chi-rectangular goodness out-of fit, [chi square] = 1.19, df = dos, P = 0.55), investigation away from most of the men amassed of during this time period had been pooled for further study. During that months, Operating system stage boys was in fact obtained for hours on end and displayed zero tall variations in volume according to the time captured (Pearson chi-rectangular jesus off match, [chi square] = step one.thirty-six, df = 2, p = 0.51). Additionally, the fresh frequency out of Os stage males don’t disagree rather one of the latest five first phases of the lunar stage (Pearson chi-rectangular, [chi-square] = cuatro.45, df = step three, P = 0.22).
Operating-system phase men accumulated of ranged sizes away from 165 so you’re able to 386 mm SL, and you may calico stage guys accumulated during those times months ranged inside size of 170 in order to 397 mm SL (Profile six). This new indicate length of collected Operating system phase people ( mm) was notably greater than the fresh mean period of built-up calico stage males ( mm; Mann-Whitney, U = 5455.0, df = 247, P = 0.001). Although not, that it result was not thought naturally tall, as the mature P. clathratus grow so you can lengths of more than 700 mm SL (Like ainsi que al. 1996). The shape listing of captive Os phase men (211 to help you 348 mm SL) was like attentive calico stage boys (212 to help you 343 mm SL). Operating system phase some body observed in the field varied in projected dimensions off two hundred to five hundred mm SL, while calico stage some body noticed varied sizes regarding 100 to five-hundred mm SL.
The brand new projected spawning seasons based on GSI and maturity analysis displayed a routine just like the month-to-month frequency out-of gathered Operating-system stage men
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 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).
