Effects of zinc on fin regeneration in the mummichog, Fundulus heteroclitus, and its interaction with methylmercury
Abstract
Methylmercury has been found to retard fin regeneration in the marsh killifish, Fundulus confluentus, and striped mullet, Mugil cephalus. Cadmium, which also retarded fin regeneration in killifhsh interacted antagonistically with methylmercury so that fish exposed simultaneously to the two metals exhibited growth rates comparable to controls. Current studies on the effects of zinc on regeneration in the mummichog, F. heteroclitus, and the effects of combinations of methylmercury and zinc on this process, are reported. The data indicate that in F. heteroclitus, zinc can accelerate regenerative growth, and, by so doing, can counteract the retarding effects of methylmercury. In this species, the regeneration rate of controls was similar in 3% and 1% salinity, and the methylmercury retarded growth at both salinities. This is in contrast to F. confluentus in which decreased salinities depressed the regeneration rate, thus masking the effects of methylmercury in water of .9% salinity.
