Effects of LAS-C12 (Linear Alkybenzene Sulphonate) on some of the behavioral patterns of mullet (Mugil Platanus)

Abstract

Ecotoxicology recognizes that within aquatic systems there are multiple interacting levels of organization, ranging from the cellular, to the individual, to the ecosystem level. At the level of the individual, sublethal toxicant effects are manifested in several ways, but among the most sensitive indicators of pollution stress are behavioral alterations. In particular, feeding behavior, swimming capacity, swimming performance. In this paper we used behavior for evaluated the effects of LAS-C12 in different concentrations (0,0; 1,0; 2,5 and 5,0 mg. L-1) The behavioral used were: caudal fin beaten frequency, pectoral fin beaten frequency, dorsal fin beaten frequency, operculum beaten frequency, cough frequency, routine metabolism and the time of swimming until fatigue of M. platanus in the temperature of 25ºC and salinity 35. All the behavioral observed in this work for mullet, increasing in virtue of LAS-C12 concentration. The behavioral as end point were efficient for studied the sublethal effects in mullet.
