EFFECT OF HABITAT BIOGEOCHEMICALS ON SURVIVAL OF LOBSTERS (HOMARUS AMERICANUS)

EFFECT OF HABITAT BIOGEOCHEMICALS ON SURVIVAL OF LOBSTERS (HOMARUS AMERICANUS)

Lobsters from eastern Long Island Sound (LIS) were exposed to laboratory conditions designed to simulate the habitat in western LIS during the 1999 mass mortality. Elsewhere (Robohm et al. 2005) we have shown that hypoxia and concomitant biogeochemical conditions increase the susceptibility of lobst...

Zusammenfassung:Lobsters from eastern Long Island Sound (LIS) were exposed to laboratory conditions designed to simulate the habitat in western LIS during the 1999 mass mortality. Elsewhere (Robohm et al. 2005) we have shown that hypoxia and concomitant biogeochemical conditions increase the susceptibility of lobsters to a common pathogen at normal summer temperatures. Here we report that in otherwise favorable conditions, high temperature (24°C) alone had no lethal effect on disease-free eastern LIS lobsters for weeks. However, at this temperature, moderate hypoxia (
