The invasive crab Charybdis longicollis was first reported in Mersin Bay (Mediterranean Sea/Turkey) in 1954, and since the early 1990s, its populations have been heavily parasitised by the alien rhizocephalan Heterosaccus dollfusi. In Antalya Bay, 46.6% of the trawled catch is constituted by C. longicollis. Monthly biomass values fluctuated between 67 kg km⁻² (June) and 704 kg km⁻² (October), with a mean of 260 kg km⁻². The percentage of change in females ranged from 29% in October to 53% in January. The mean carapace width of uninfected crabs was significantly larger in males (35.1 mm) than females (30.6 mm). Male crabs (34.3%) were more heavily parasitised than females (12.1%). The reduction in size of the chela and broadening of the abdomen are two characteristic modifications of infected males. The size at first maturity was estimated at CW = 24.7 mm. Ovigerous females were found all year-round but were more abundant in spring. Male and female individuals of C. longicollis displayed a maximum of three and one modal groups per year, respectively. Natural mortality (M) was estimated as 1.1 year⁻¹ for male crabs.

入侵螃蟹Charybdis longicollis于1954年首次在梅尔辛湾（地中海/土耳其）报道，自1990年代初以来，其种群已被外来根瘤菌Heterosaccus dollfusi严重寄生。在Antalya湾，拖网渔获的46.6％是由构成C. longicollis。每月生物量值在67 kg km ^-2（6月）和704 kg km ^-2（10月）之间波动，平均为260 kg km ^-2。女性变化的百分比从10月的29％到1月的53％不等。男性（35.1毫米）未感染螃蟹的平均甲壳宽度明显大于女性（30.6毫米）。雄性螃蟹（34.3％）比雌性（12.1％）严重寄生。螯合大小的减少和腹部的扩大是被感染男性的两个特征性改变。首次成熟时的尺寸估计为CW = 24.7 mm。一年四季都发现雌雄同体，而春季则更为丰富。每年C. longicollis的男性和女性个体最多显示三个和一个模态组。雄性蟹的自然死亡率（M）估计为¹ . ¹年^-1。
