Changes in the character of gills of the Red sea fish

The morphological structure of gills of the Red Sea fish, caught in areas with different levels of anthropogenic impact is studied. It is shown that the frequency of pathological changes of the gills is higher in the port area, but it is lower in the relatively clean area. The gills of relatively sedentary fish are more susceptible to the negative effects of the environment, while the gills of active large-scale mullet are less vulnerable. The character of the changes in the gills of the examined fish does not depend on their kind.
