Primary: neuroendocrine responses – which causes particular species to migrate as soon as they are exposed to a new stressor this may be chemical or when threatened by a new predator (Alien invasive fish species);
Secondary: Metabolic responses – which may have an effect on the nutrient cycling of fish species; and;
Tertiary: Desiccation – where the stressor or impact is too large resulting in fish kills.
