Managing the health of mussel (Mytilus spp.) seed from Newfoundland - the effects of thermal stressors, transport times, storage conditions and anti-biofouling treatments on the short-term and long-term performance of mussel seed
The application of chemical treatments to rid seed of Aquatic Invasive Species (AIS), in conjunction with temperature shocks and long transport times, has the potential to adversely affect the health and long-term performance of mussel seed from Newfoundland, which are approximately 30-40 mm in leng...
