Shallow benthic organisms, e.g. bivalves, are exposed to multiple stressors on the shallow coast. To cope with these stressed condition, they use physiological mechanisms for their limited mobility. I investigated the combined effect of salinity, wave actions, and food limitation on Mya arenaria, using bioenergetics approach. I assessed the possible energy trade offs between different fitness related functions, such as burrowing, osmoregulation and basal maintenance. I found, high priority of escape behavior can lead to trade offs with maintenance function, like osmoregulation.<eng>
