Document Summary
Live in water, excrete waste in their environment. Energy transfer between water and the body is very efficient. Any heat the animal is producing is directly transferred to the environment. Breathing through gill = large sa = large heat transfer. Most fish produce ammonia as the end n waste. Extremely efficient, not converting ammonia to urea. Need to get rid of ammonia which is very toxic. Large eggs that hatch to yolk sac fry (embryo) Still relying on what is contained in the egg, but free swimming. Have black spots on skin before smoltification for salmon. Turn completely silver after smoltification for salmon. Can feed them salt to activate na/p atpase. Faster growing in ocean than in freshwater. May be due to the perception of space. Egg yolk sac fry (embryo) swim up fry fry fingerling parr smolt -> juvenile adult broodstock. Stages that are completely different from each other.
