Abstract
The coast of Milazzo is characterized by the presence of several production activities such as the Refinery, the steelworks, the electric point station, the commercial-tourist port, the shipyards, the fishery and the agricultural plants which involving the land-sea center. The aim of this research is to make a check on the fish fauna that inhabits both coasts, the west and east, to evaluate health status of fish , creating a biological model of inquiry that can be used both for assessing the toxicity of produced water, which for the degree of environmental contamination of this coastal area Milazzo potential toxicological impact [1]. A morphological analysis on the most common sedentary fish was carried out in particular Boops boops, Lithognatus mormyrus, Diplodus annularis, used as a bioindicator fish [2]. After sampling in different parts of the coast, it is made the removal of organs of interest, then we proceeded to the preparation of durable prepared for light microscopy. Were examined intestine samples that, in fish caught in the eastern, showed a morphological picture altered, with an increase of cells with mucous hypersecretion in the ridges, disorganization of the parenchyma and disintegration of the apical cells [3, 4]. By contrast it has been observed in fish of the western coast, exposed to less impact toxicology, a least altered morphological picture.Pubblicazioni consigliate
