“…Removal of the fouling organisms is labourintensive and, thus, expensive, and is an ongoing problem for shellfish farmers. To help counter this problem, Ross et al (2004) investigated the biological control of fouling in great scallop Pecten maximus culture by introducing sea urchins (Echinus esculentus and Psammechinus miliaris) and hermit crabs Pagurus spp. to scallop nets.…”

“…valve opening and closing) or compete with them for space and food, and slow their growth (Lodeiros & Himmelman 2000). The removal of foulers is thus necessary and represents an additional cost to shellfish farmers (Hidu et al 1981, Ross et al 2004). In addition, cultivated bivalves and foulers may attract predators to aquaculture areas.…”

We investigated the predation behaviour of rock crab Cancer irroratus and green crab Carcinus maenas in laboratory experiments in autumn 2006 and spring 2007 during various conspecific and heterospecific challenges. The number of prey eaten by a focal crab during a given challenge was recorded for both crab species using competition treatments (solitary crab, 2 conspecifics or 2 heterospecifics) crossed with 2 different prey densities (4 or 30 mussels) and 3 different temperatures (5, 12 or 20°C). To validate laboratory results, complementary field experiments were carried out in aquaculture leases in Prince Edward Island, Canada, in 2007, during which crab stomach contents from identical competition treatments were studied and mussel socks were surveyed monthly for crab abundance. In the laboratory, predation rates of both crab species generally increased with temperature and mussel density, and were not affected by the presence of a heterospecific regardless of the season. During autumn 2006, the Temperature × Mussel density interaction influenced the predation rate of rock crab while only temperature affected the predation rate of green crab. During spring 2007, the predation rate of green crab varied again according to temperature whereas the predation rate of rock crab was affected by the Temperature × Mussel density × Competition interaction. In the field, blue mussels Mytilus edulis were the most abundant food item observed in stomach contents. The competition treatments did not affect the stomach contents. Both crab species displayed different abundance patterns and seemed to avoid each other on mussel socks. Overall, our results suggest that the 2 crab species can potentially coexist.

“…A number of studies and reviews (e.g. Ross et al 2004, McKindsey et al 2011) have highlighted the importance of physical structures (nets, cages, tubes, etc.) used in bivalve culture, since they provide novel substrata for the establishment of various invertebrate, algal, and microbial communities.…”
