Abstract

Recent rapid industrialization in developed and even developing countries and the resultant high demands for industrial products, has led to the need for easy industrial disposal. The cheapest method for such disposal during the past few decades has been by discharged of the effluents into the nearest river or lake. The extent of the resultant damage on the environment of water pollution from a variety of sources has given rise to great concern. Heavy metal pollution of the aquatic ecosystem could occur either from waste disposal or at mining and processing sites by the leakage of minerals into the rivers. Flood water from mines may also carry high concentrations of HEAVY METALS into the rivers, and fish SPERM would then be exposed to these metals. This study has been navigated to look at some ultramorphological changes of COPPER bioaccumulation on two teleost species.SPERM from CARP and TROUT incubated with different concentrations of COPPER for 3 hours. The specimens were processed and morphological changes on SPERMs were viewed by scanning electromicroscopy. The results showed that COPPER at concentrations higher than 10 ppm insert extensive morphological effects on SPERM (mainly enlarging SPERM's head), so they cannot swim freely and fertilized ova. Mean percent of abnormal SPERMs were 75, 100 and 100% for 10,50 and 100ppm COPPER concentrations, respectively.
