Metallothionein Proteins in Aquacultural Products

Nowadays, water and environment have been polluted in a fast manner by domestic, agricultural and industrial activities. As a matter of fact that water, soil and atmosphere are polluted, aquacultural products in the nature or cultivated habitat are contaminated by heavy metals. Therefore, there is a protective protein called metallothionein in aquacultural products to protect them from heavy metal toxicity. Metallothionein is well used as heavy metals indicators in aquatic organisms such as brown trout, white shrimp, freshwater mussel and crab., Descirption of the metallothionein and its features, and the studies evaluating the metallothionein as heavy metals indicators in aquatic organisms is presented in this review
