High fishing intensity reduces females' sperm reserve and brood fecundity in a eubrachyuran crab subject to sex-and size-biased harvest
LM Pardo, MP Riveros, JP Fuentes… - ICES Journal of …, 2017 - academic.oup.com
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 …

Sperm allocation in response to a temporal gradient in female reproductive quality in the stone crab, Hapalogaster dentata
T Sato, S Goshima - Animal Behaviour, 2007 - Elsevier

Sperm limitation: possible impacts of large male-selective harvesting on reproduction of the coconut crab Birgus latro
T Sato, K Yoseda, K Okuzawa, N Suzuki - Aquatic Biology, 2010 - int-res.com
