Seasonal influence of wave action on thread production in Mytilus edulis.
The blue mussel Mytilus edulis maintains a strong attachment to the substrate in high energy environments by producing byssal threads. On the shores of Rhode Island, USA, mussel attachment strength increases twofold in spring compared to that in the fall. While many factors could influence attachment strength (temperature, food supply, predator cues, etc.), it has been proposed that the variati...
متن کاملThe effect of high-pressure spraying for tunicate control on byssal thread characteristics in the cultured blue mussel (Mytilus edulis Linnaeus, 1758)
Mussel growers in Prince Edward Island (PEI), Canada, currently use high-pressure water spraying (~700 psi) to mortally injure or dislodge invasive tunicates from mussel product and gear. An added benefit of this process may be the stimulation of byssal thread production, leading to improved mussel attachment. This study measured byssal thread abundance and thickness in cultured blue mussel Myt...
متن کاملSeasonal variation in mussel byssal thread mechanics.
The blue mussel, Mytilus edulis, attaches itself to the substrate by producing a radially arranged complex of collagenous byssal threads. The strength of byssal attachment, or tenacity, has been shown to vary seasonally on Rhode Island shores, increasing twofold in spring in comparison with fall. It was previously assumed that this seasonality was due to increased thread production following pe...
متن کاملImpact assessment of an invasive flatworm, Convoluta convoluta, in the Southern Gulf of Maine
Convoluta convoluta (Abildgaard 1806) is a small (2–3 mm long) acoellous turbellarian flatworm from Europe that has invaded the Gulf of Maine within the last 5 years. Although it has been reported in densities of up to 19 individuals/cm, its ecological impact remains unknown. In its native habitat, it consumes harpacticoid copepods and primary settling mussels < 0.5-mm shell length. This study ...
متن کاملJournal of Marine Biology and Aquaculture
The bivalve aquaculture industry has become an important socio-economic component of many coastal communities throughout the world and marine molluscs presently account for 60% of global marine aquaculture production[1]. Largely cultivated on the east of Canada (over 20,000 tons per year), the mussel industry represents an annual market of around $30 million[2]. Wild seed collection remains a c...
