Multiple studies have identified sex ratios in adult American lobster (Homarus americanus)
populations that are skewed toward males in some locations and females in others. The …

An approximate 1: 1 sex ratio of American lobsters can be skewed due to environmental
factors or fisheries management. Substantial skewness can impact mating behaviour and …

The female reproductive output and potential recruitment (PR) were studied in three
Argentinean southern king crab (Lithodes santolla and Lithodes confundens) stocks: in the …

Large, male snow crab (Chionoecetes opilio) off Newfoundland and Labrador were heavily
exploited throughout their range from 2015 to 2018 leading to biological concerns about the …

Crustacean fisheries often preferentially or exclusively harvest males, resulting in selection
that alters sex ratios in fished populations. Sex-biased fisheries may occur when males are …

Size-selective male fisheries may result in sperm limitation whereby the number of sperm is
insufficient to fertilize all oöcytes produced by females. In eubrachyuran crabs, females have …

Harvesting is often size‐selective, and in species with sexual size dimorphism, it may also
be sex‐selective. A powerful approach to investigate potential consequences of size‐and/or …

For polyandrous species where females have sperm storage structures, males develop
several strategies to avoid sperm competition and thus to maximize the number of eggs …

Our aim was to describe the reproductive system of males and the formation of sperm
packages in the seminal receptacle (SR) of recently mated females of the arrow crab …

Current fishery management practices in both the US Gulf of Maine and southern Norwegian
clawed lobster fisheries primarily focus on conserving mature females to maximize egg …
