1. Introduction
On the Pacific coast of North America, in British Columbia (BC) Canada, there are four Mytilus species of marine mussels; the native Mytilus trossulus (or bay mussel) and M. californianus (California mussel), as well as two non-native cultured species M. edulis (blue mussel) and M. galloprovincialis (Mediterranean mussel). Mytilus trossulus, M. galloprovincialis and M. edulis are considered together as the ‘Mytilus edulis species complex’; they are phenotypically similar and are known to hybridize readily (Shields et al., 2008), hence genetic methodologies are needed to reliably distinguish individual species or hybrids (Heath et al., 1995). Whilst there have been introductions of the nonnative species for aquaculture purposes in BC since an initial transfer in 1987, Heath et al. (1995) speculated that other sources of entry may have occurred through ballast water or hull-fouling, or that these species may have been present in BC for a considerable time period and were not previously accurately identified (N. Bourne, Fisheries and Oceans Canada, pers. comm.). Intentional introductions of M. edulis occurred due to difficulties culturing the native M. trossulus in the 1980s, including post-spawning mortalities (Bower, 1989; Emmett et al., 1987) and shell breakages in market processing. Likewise, culture of M. californianus was not pursued due to very strong byssus attachments and tough meats, making it an undesirable product from a culture standpoint (B. Kingzett, Vancouver Island University, pers. comm.). Fisheries and Oceans Canada developed a mussel aquaculture program in 1987, when M. edulis broodstock were intentionally introduced to BC from Prince Edward Island (PEI) (Bill Heath, BC Ministry of Forests, Lands and Natural Resource Operations, pers. comm.). This initial introduction is believed to have been the base broodstock population for a number of aquaculture operations in BC, including those sampled in this study. Since that time, aquaculture operations have undertaken traditional selective M. edulis breeding programs for different visual qualitative and quantitative traits, such as colour morphs and larger size, but no pedigree-assisted broodstock programs are currently being employed.
