Document Summary
An area of water that we use for fishing. Dominant commercial fisheries group: finfish, crustaceans, mollusks and kelp. Individuals acting for their own self-gain, will act contrary to the group"s self-gain. Controlling fishing effort through limits on harvest, gear, crew size, area, season, etc. Temp can have a hard time regulating if too high or low. Do can have an effect of how well a fish lives. Sediments turbidity can reduce photosynthesis and kill larvae. Gills fish are open to the environment. High density, high pressure with depth, causes stress and physiological problems. Explain the characteristics of fish and physical properties of water, i. e. temperature, do, sediments, gills, growth, ontogeny. High population diversity because of reproductive isolation. Evolutionarily significant units, designation of critical habitat under the esa. One tiny drop in mortality = enormous growth. Complex life histories often result in high juvenile mortality. Because they are the base of the trophic web.
