Popis:	We report the effects of short daily exposures to sublethal increases in water temperature during the egg and larval stages on the development of the schooling behavior of the little sand smelt Atherina mochon. The experiments were conducted to simulate the periodic exposure of different developmental stages to a transient thermal plume caused by the discharge of heated effluents into the spawning environment. Exposures were administered for eggs only, larvae only, and both eggs and larvae and consisted of nonlethal increases in water temperature from a 20°C acclimation temperature to 28.5°C over a period of 30 min, maintenance at 28.5°C for 15 min, and a gradual reduction to 20°C over 35 min. Heat treatments were administered to the egg-only and larvae-only groups for 10 consecutive days each; those administered at both the egg and larval stages were for 20 consecutive days. Behavioral testing of larval fish at 10, 15, 20, 25, 30, and 35 d posthatch showed significant modification or retardation...
