Answer: Bioaccumulation

Explanation:

Bioaccumulation refers to how living organisms like fishes accumulate toxic substances in their body tissues through feeding on poisoned smaller organisms or by diffusion of these substances from their aquatic environment.

As the fish ages, the deposits of toxic substances like mercury levels increases from 0.5 mg/kg to 3 mg/kg.
