“…Previous studies showed that the presence of shore crabs (effluent) stimulates the creation of byssus (Reimer and Tedengren 1997;Leonard et al 1999) at a speed that can result in 10 byssus threads after 6 h and, in the field, to attachment strengths (after 30 days) of about 16 N (Côté 1995), which was twice as high as it was when no crabs were present (Leonard et al 1999). Attachment strength is related to the sum of individual byssal threads (Bell and Gosline 1996), and mussels that are more strongly attached are less likely to be taken by crabs (Lin 1991).…”

“…This defence is widely used and has been known with regard to Homarus sp., C. maenas and Cancer sp. feeding on Mytilus edulis (Côté 1995;Reimer and Tedengren 1997;Garner and Litvaitis 2013), Callinectes sapidus feeding on Ischadium recurvum (Brown et al 2011) and Acanthocylus gayi feeding on Perumytilus purpuratus and Semimytilus algosus (Caro et al 2008), where A. gayi was selecting the mussels with the weakest attachment. Since shore crabs display competitive behaviour for food, dense mussel aggregations increase the intraspecific interactions between the crabs that might lead to a decrease in the predator-prey interactions in the field (Sneddon et al 1997;Smallegange and Van Der Meer 2007).…”

Mussel losses peak after relaying seed on culture plots. The present paper is an attempt to examine the role of shore crab predation and initial mussel density on mussel losses in mussel bottom culture using an intertidal culture plot as a case study. Because of their small size and loose attachment, mussels are particularly vulnerable to predation at this stage, as well as to handling stress and intraspecific competition. In the experimental field plots (1 9 1 m) in the intertidal Oosterschelde, three different densities (1, 5 and 10 kg m -2 ) of mussel seed are laid, with half of the experimental plots protected from predation by means of exclosures. Duration of the experiment was 5 weeks (AugustSeptember 2012) post-seeding. Protection was the major factor accounting for biomass production, followed by mussel density. Loss rates increased with mussel density, both in the exclosures and in the exposed plots. Losses in the exclosures with the lowest density were still 45 %. There are indications that handling stress prior to the start of the experiment played a major role in these losses. At the higher densities in the exclosures, losses increased to 72.1 % and were not significantly different between 5 and 10 kg m -2 . About one-third of the total loss (32.6 %) was attributed to shore crab predation. development during the experimental period was followed and was found to be a slow process that was insufficient to protect mussels from crab predation at the sheltered experimental location.

Thus, it is possible that mussels avoided dead shells in our experiments because of chemical cues that remained within the empty shells after removing the flesh just before starting the experiments.…”

A B S T R A C TIn both sedimentary and rocky coastal habitats, epibenthic mytilid mussels use byssal threads for attachment to the substratum and to form beds with high densities of individuals. Number and attachment strength of byssal threads can be adjusted according to external factors such as hydrodynamic forces or predators, but it is unknown whether mytilid mussels distinguish between substrata of different quality for byssus attachment in different habitat types. In field studies, we examined the attachment strength of the mussel Perumytilus purpuratus growing on Pacific hard-and soft-bottom shores in Chile and of the blue mussel Mytilus edulis from an Atlantic rocky shore in France and a sedimentary shore in the North Sea (Germany), respectively. In additional laboratory experiments, we studied mussel substratum selectivity of both bivalve species from soft and hard bottoms by offering living versus dead, barnacle-fouled vs. unfouled, and firmly attached vs. loose conspecifics. In the field, attachment strength of P. purpuratus on hard bottoms was substantially higher than on soft bottoms even though mussels produced more byssus in the latter habitat. In contrast, blue mussels M. edulis showed only a slightly reduced attachment strength on soft compared to hard bottoms. In the soft-bottom habitat, fouled individuals from the edge of a blue mussel bed were especially strongly attached. In the byssus attachment behavior experiments, P. purpuratus from both habitats showed a significant preference for living conspecifics and those from soft bottoms preferred firmly attached conspecifics. Blue mussels had no preference for particular conspecifics except those from soft-bottom habitats, which preferred fouled over clean mussels. In general, in the choice experiments hard-bottom M. edulis produced more byssus. Our results confirmed that mytilid mussels may show active substratum choice for byssus attachment, which depends on mussel species and habitat type. The results suggest that mussels are adapted to a particular habitat type, with P. purpuratus showing lower adaptation to soft-bottom areas while M. edulis shows successful strategies for both environments.
