- Advantage –Increasing Demand.
- Disadvantage –Operating Costs.
- Disadvantage –Water Purification.
- Disadvantage –Disease and Infection.
What are the advantages of fish farming class 9?
An advantage of composite fish culture is that it increases the yield of fish. Nearly, five or six different species are grown together in a single fish pond. The survival rate of fish increases and their yield also increases without affecting the other species.
What are the economic advantages of fish farming?
- Alternative Food Source. Fish and other seafood are good sources of protein.
- Alternative Fuel Source. Algae are slowly being developed into alternative fuel sources by having them produce fuels that can replace contemporary fossil fuels.
- Increase Jobs in the Market.
- Reduce Sea Food Trade Deficit.
What are the disadvantages of fish farm?
Disadvantages in Fish Farming
- Disease. Keeping fish in close proximity increases the chances of disease.
- Environment. Fish farms can have a harmful effect on the local environment.
- Protein Efficiency. Many farmed fish –such as salmon, bass and cod–are carnivorous.
- Set-up Costs.
- Worker Safety.
Why is fish farming bad?
Fish farms, or “aquafarms,” discharge waste, pesticides, and other chemicals directly into ecologically fragile coastal waters, destroying local ecosystems. Waste from the excessive number of fish can cause huge blankets of green slime on the water’s surface, depleting oxygen and killing much of the life in the water.

Why are fish important to humans?
Fish plays an important role in fighting hunger and malnutrition. Fish is not only a source of proteins and healthy fats, but also a unique source of essential nutrients, including long-chain omega-3 fatty acids, iodine, vitamin D, and calcium. Fish can sometimes serve as a solution to existing health problems.
What are three advantages to farming fish?
Advantages of Fish Farming
- Stable supply with fish.
- Relief for our wild aquatic animals.
- Waste reduction related to commercial fishing.
- Protection of habitats.
- Mitigation of the endangered species problem.
- May be necessary to feed our growing world population.
- Local income source.
- Employment opportunities.
What are the environmental benefits of fish farming?
Aquaculture could help decrease the effects of human consumption of fish on freshwater and marine water habitats by producing food without taking away from overfished environments. Fish, plants and shellfish produced in aquaculture farms are also used to rebuild species populations in freshwater and saltwater habitats.
