摘要: Abstract To determine if natural populations of the eastern oyster possess resistance to Perkinsus marinus, progeny representing several stocks from Chesapeake Bay and Gulf Mexico were deployed at two sites within Bay. Mortality, P. marinus infection (prevalence intensity), shell height, condition index, energy reserves (glycogen, protein, lipid) compared between these stocks. Oyster had higher intensities Dermo than Louisiana stocks, with differences among individual Throughout 2-y study, a Dermo-resistant stock Tangier Sound (CTS), was identified. Despite approaching those susceptible Rappahannock River (CRB) (LOB), CTS consistently lower mortality for grow out, comparable hatchery disease-resistant strain (XB). At site (Port Kinsale) where significant parasite LOB ...
