Abstract

Sea pollution by various organic and inorganic matters has become an increasingly serious problem. Irrespective of their origin, pollutants -especially those in harbours - have a hazardous effect on living marine organisms. The mullet (Mugil cephalus) inhabits harbours that are rich in food. The coast crab (Carcinus aestuari Nardo) is also frequently found there. Our study was designed to elucidate the activity of oxidative enzymes (LDH, SDH and NADPH) in the gills, liver, digestive gland, stomach and intestines of mullet and coast crab in two sites: Zadar's marina and harbour, and the area southeast of Krbela island. The activity of NADPH, and particularly that of LDH and SDH, showed increased activity, notably in the gills and liver of both species from the Zadar marine and harbour. LHD activity in the gills, liver, stomach and intestines of coast crab from the Zadar site was more marked than in mullet from the same group. The activity of oxidative enzymes ithe studied organs of mullet and coast crab inhabiting the Zadar site indicated effects of heavy metals, oil and oil derivatives, kaolin, chlorinated hydrocarbons and pesticides on the body
