Population dynamics of the Mediterranean green crab Carcinus aestuarii Nardo, 1847 (Crustacea: Portunidae) in the Gediz Delta (İzmir Bay, Eastern Aegean Sea)
A total of 6265 Mediterranean green crabs Carcinus aestuarii were sampled from the Gediz Delta in the eastern Aegean Sea (Turkey) during 24 sampling surveys with a 15-day interval from November 2014 to October 2015. The overall ratio of males to females was 1.8:1. Males were predominant in all sampl...

| 520 | |a A total of 6265 Mediterranean green crabs Carcinus aestuarii were sampled from the Gediz Delta in the eastern Aegean Sea (Turkey) during 24 sampling surveys with a 15-day interval from November 2014 to October 2015. The overall ratio of males to females was 1.8:1. Males were predominant in all sampling surveys, except in September 2015. The ranges of total weight (W) and carapace width (CW) for all crabs were 0.19–45.74 g and 8–53 mm. Male crabs were, on average, larger and heavier than females. The W–CW relationships were W=0.0004×CW2.88 for females, and W=0.0003×CW2.96 for males. The estimated von Bertalanffy growth parameters for females were: CW∞=49 mm, K=0.82 year-1 and t0=-0.9 year, and for males CW∞=54 mm, K=0.92 year-1 and t0=-0.96 year. The total mortality rates were 2.25 and 2.27 year-1 for females and males, respectively. The breeding season spans from mid fall to early spring peaking in winter. The recruitment of juveniles to the lagoon happens predominantly in summer. The median size at first maturity was 30.6 mm for females and 41.5 mm for males. The average potential fecundity estimate was 63565±36519 oocytes per female crab while the average realized fecundity was 42810±33310 eggs. | ||
| 520 | |a Sakupljeno je 6265 jedinki mediteranskog zelenog raka Carcinus aestuarii iz delte rijeke Gediz u istočnom Egejskom moru (Turska) tijekom 24 ispitivanja uzoraka u intervalima od 15 dana od studenog 2014. do listopada 2015. godine. Ukupni omjer mužjaka i ženki iznosio je 1:8. Mužjaci su bili prevladavajući u svim istraživanjima uzoraka, osim u rujnu 2015. Rasponi ukupne mase (W) i širine glavopršnjaka (CW) za sve rakove iznosili su 0,19–45,74 g i 8–53 mm. Mužjaci su bili u prosjeku veći i teži od ženki. Odnosi ukupne težine i širine glavopršnjaka su iznosili W = 0,0004 × CW2,88 za ženke, a W = 0,0003 × CW2,96 za mužjake. Procijenjeni parametri rasta ženki prema von Bertalanffy-jevoj jednadžbi iznosili su: CW∞ gdje je = 49 mm, K = 0,82 godina-1 i t0 = -0,9 godina, a za mužjake CW∞ = 54 mm, K = 0,92 godina-1 i t0 = -0,96 godina. Ukupna smrtnost ženki iznosila je 2,25 godina-1 dok je za mužjake iznosila 2,27 godina1.Razdoblje razmnožavanja seže od sredine jeseni do ranog proljeća, te dostiže vrhunac zimi.Novačenje mlađi u laguni se pretežito odvija u ljetnom periodu. Srednja veličina jedinki pri prvoj spolnoj zrelosti bila je 30,6 mm za žene i 41,5 mm za mužjake. Prosječna potencijalna procjena plodnosti iznosila je 63565 ± 36519 oocita po ženki rakova, dok je prosječna ostvarena plodnost iznosila 42810 ± 33310 jajašaca. | ||
