Sperm depletion in males can occur when polygynous species are intensively exploited
under a male-biased management strategy. In fisheries involving crabs species, the effects …

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 …

This study examined whether sperm allocation by males can limit sperm passed to females
in fished spiny king crab populations in which large males are selectively fished. We …

Males with limited sperm reserves should allocate sperm efficiently during the reproductive
season. As efficiency depends on the temporal distribution of mating opportunities with …

For many biological resources, larger males are more likely to be harvested than smaller
ones. In such harvested populations, the remaining males are relatively small and …

In populations subjected to size-selective harvesting of large males, remaining males are
small and participate in more matings than in pristine populations. The reproductive rate of …

Two laboratory experiments investigated mate guarding and sperm allocation patterns of
adult males with virgin females of the snow crab, Chionoecetes opilio, in relation to sex ratio …

Sperm reserves are costly to produce and so the development of different sperm allocation
strategies may be advantageous. Knowledge of sperm allocation strategies is important from …

Sperm limitation, where the reproductive output of a population is restricted by its sperm
production, is a concern for several crustacean species around the world. We used a …

Fisheries that selectively harvest males have the potential to diminish the reproductive
success of females due to reductions in the transfer of sperm and seminal fluid during …
