Examples of Sensitivities
Species
• Scallop and fish eggs that rely on a gyre to return them to their habitat on a certain day or week
• Fish eggs in streams or on the sea floor that require a minimum current speed for oxygenation
• Species that require an influx of freshwater to induce spawning or to kill predators
• Temperatures above or below the stock’s lethal limit
Societal
• Immobility of communities dependent on one type of species
• Societies without money needed to buy replacement foods
• Fishers unable to deal with new vessel and gear demands
Species Sensitivities
• Changes: temperature, sea level, river flows, salinity, currents, winds, storms, and variability
• Species are dependent on one or more of above
• Species can move rapidly if habitat and paths exist
• Fish are cold-blooded. Life processes, like growth, are faster when warmer (within limits)
• Many species have narrow ecological niches, but there are many species to fill niches
• Small changes cause large disruptions to a species
• Mixes will change until stability is reestablished.
