René Girard (1923-) used to be Professor of French Language, Literature and Civilization at Stanford collage from 1981 until eventually his retirement in 1995. Violence and the Sacred is Girard's significant research of human evil. Girard explores violence because it is represented and happens all through background, literature and fantasy.

Of prime importance is temperature, since this is the physical attribute of the water that will have the greatest controlling influence on growth rate. Seasonal changes in temperature may be important in planning production strategies, since it would be desirable, for example, for peak temperatures to coincide with high stock holdings to obtain the greatest weight gain from the most favourable conditions. The avoidance of temperature extremes will also be important, during both the summer and the winter months, to avoid prolonged periods of low growth and low food conversion efficiencies, and even mortalities under the most severe conditions.
Specialised chloride cells in the gills remove ions such as sodium and chloride, while the kidneys produce small volumes of very concentrated urine. u. are subject to the opposite fluxes: salts leave the body and water enters by osmosis. Fish that tolerate both environments are able to do so because chloride cells can take up monovalent ions to replace those lost, and the kidneys produce copious amounts of dilute urine to counteract the osmotic flux. Unless the surrounding water is isotonic with the body fluids, energy is constantly used to maintain the body fluids’ composition.
Atlantic halibut yolk-sac larvae held at 10 lux show significantly better growth and survival than those kept at 1000 lux, probably because their activity is greater at the higher light intensity, resulting in less of the yolk reserves being available for growth. Yolk-sac cod larvae develop faster in constant darkness than larvae kept under a diel light cycle, since swimming activity is 6–10 times less in darkness. Once exogenous feeding begins, a suitable light level is necessary for active feeding to be successful.
