Culture and behavior of selected estuarine fish and shellfish in aquaria receiving effluent water from a power plant
Sixteen species (2 molluscs, 2 crustaceans, and 12 fishes) were used as biological monitors in flow-through aquaria. The aquaria received effluent from Houston Lighting and Power Company's Cedar Bayou generating station located in Chambers County, Texas. Growth and survival of organisms were monitored in ambient and thermally regulated water (20, 25, and 30/sup 0/C). Behavior experiments were carried out with several of the monitor species, Cyprinodon variegatus, Mugil cephalus and Mugil curema. R. cuneata, C. virginica, L. xanthurus, M. undulatus, C. faber and M. cephalus were analyzed for heavy metals and pesticides and were evaluated according to current Food and Drug Administration (FDA) standards. All organisms were found to be within the established FDA tolerance levels and are therefore considered fit for human consumption. C. variegatus was tested at varius sex-ratios to determine whether a particular ratio could maximize the number of young produced. No statistically significant difference was found in the number of young produced; however, population density and sex-ratio significantly increased total adult mortality. The swimming and feeding behavior of M. cephalus and M. curema was observed and described. The number of food bites was significantly affected by the interactions of culture, species, and density. During polyculture situations there were significantly more food bites, long traverses and total traverses than in monoculture situations.
