Question

Fish are the good source of proteins and pisciculture (fish forming) has increased the
yield of fish to an extreme extent. Due to this expansion, fish population is suffering.
Mention any four harmful effects.

Answer 1

Seafood is an excellent source of protein because it's usually low in fat. Fish such as salmon is a little higher in fat, but it is the heart-healthy kind: it has omega-3 fatty acids.

Given population growth, expanding urbanization, and rising incomes in the developing world, this trend is expected to continue. Because levels of capture fish production have stagnated over the past decades, 1 the world will thus be more dependent on aquaculture in the coming decades.Direct impacts include overfishing that leads to population declines, while indirect impacts can include disruption of aquatic food webs, when predator/prey interactions are affected by changes in fish populations.
