The Persian Gulf is a shallow water body, with an average depth of 35–40 m and an area of about 240 km2 which is connected to oceanic waters through the Strait of Hormuz. In recent years, due to various environmental events including the world’s largest oil loss in 1991, ship traffic, oil transportation and other pollution, the region is in crisis.

It is known that about 30% of total world oil shipping takes place in the Persian Gulf. Heavy metal pollution of the water system of anthropogenic origin is a serious threat in the food chain due to toxicity, long-term sustainability, bioaccumulation and biomagnifications.

After entering into the aquatic ecosystems, heavy metals accumulate in some of the tissues of aquatic organisms and eventually enter into the food chain. Uptake and accumulation of heavy metals in marine fish depend on ecological, physical, chemical and biological conditions of the water body, type of element and the physiology of the animal.

Because of the economic and nutritional value of Tylosurus crocodilus (Hound needlefish) and increasing pollutants in the Persian Gulf, the present study was conducted to study the concentration of some heavy metals (Cu and V) in the muscle, skin and gill tissues of T.crocodilus in the Bahregan region.
