What is the major problem in fish farming?

Thus, a major problem in fish farming is the lack of availability of good-quality stock. To overcome this problem, ways have now been worked out to breed these fish in ponds using hormonal stimulation. This has ensured the supply of pure fish stock in desired quantities.

How can fish result in environmental problems?

Chemicals and pesticides (used in some fish farming to control parasites and disease) can also contaminate the area and impact surrounding marine life.

In which ways does overfishing lead to decreased biodiversity?

Is there any bad impact of aquaculture to the ecosystem?

Fish farms can impact wild fish populations by transferring disease and parasites to migrating fish. Aquaculture can also pollute water systems with excess nutrients and fecal matter due to the large numbers and concentrations of farmed fish. Sometimes equipment used in aquaculture can be problematic.

What are the negative effects of aquaculture?

Fish produce waste, and their waste has the potential to build up in the surrounding area. This can deplete the water of oxygen, creating algal blooms and dead zones.
