Mussels Mytilus as Model Organisms in Marine Biotechnology
Bivalve molluscs belonging to the genus Mytilus are distributed throughout the world and are extensively used as model organisms in many farming studies: over 20 countries report regular harvests of farmed mussels but world production is dominated by two countries, China and Spain (Hichman, 1992). New information coming from molecular and genetic studies of mussel reproductive biology and ecology (see Rawson and Hilbish, 1995; Saavedra et al., 1996) is characterized by possible implications for the assessment of stocks, for their conservation, maintaining, and restocking. At the same time, because mussels Myilus, more than other group of bivalve molluscs, are now used in developmental biology (Mikhailov et al., 1995, 1996a; Togo and Morisawa, 1997), the information presented in our report will serve as a starting point for those wishing to extend such studies to marine biotechnology.
