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
What is the disadvantages of aquaculture?
Though aquaculture can help fish to survive and thrive, it’s also been known to destroy fish species Farmers need to be intentional about the fish they are breeding and releasing to avoid issues in the future The environment must be monitored for disease, which can also wipe out the whole population
Which of the following is a negative consequence of aquaculture?
The negative environmental impacts aquaculture has had are nuanced Nutrient buildup happens when there is a high density of fish in one area 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
What are the pros and cons of aquaculture and fish farming?
Fish Farming Pros & Cons Pro: Replenishment Fish farming allows us to replenish the food fish supply at a faster rate than the oceans can produce it, allowing suppliers to keep up with demand Pro: Employment Pro: Nutritional Provisions Con: Environmental Damage Con: Feeding Con: Lice and Bacteria
What are the limitations of fish farming?
As fish farms are run now, in fact, they themselves pose a threat to wild fish Farmed fish frequently escape into the wild, creating a kind of genetic pollution, and carnivorous species like farmed salmon are fed protein from wild fish, a practice that does nothing to reduce our dependence on the overfished ocean

What are three negative effects of aquaculture?
The most common negative environmental impacts that have been associated with aquaculture include: waters eutrophication, water quality, alteration or destruction of natural habitats; introduction and transmission of aquatic animal diseases (FAO, 2006a)

How aquaculture practices affect biodiversity?
Aquaculture has some positive impacts on biodiversity; for example, cultured seafood can reduce pressure on overexploited wild stocks, stocked organisms may enhance depleted stocks, aquaculture often boosts natural production and species diversity, and employment in aquaculture may replace more destructive resource Jan 1, 2009
What is a disadvantage of aquaculture compared to harvesting wild caught fish?
Some aquacultures can harm the environment Chemicals and waste from fish farms can spread and contaminate the environment around them This can even affect local wildlife and spread diseases to wild fish populations
Why is aquaculture bad?
But large-scale aquaculture can have significant environmental consequences It can take a lot of wild fish to feed certain farmed fish And when tons of fish are crowded together, they create a lot of waste, which can pollute the ocean Fish farms can also be breeding grounds for disease
What are 2 pros and 2 cons of aquaculture?

What is the advantages and disadvantages of fish farming?
Top 10 Fish Farming Pros & Cons – Summary List Fish Farming Pros Fish Farming Cons Income source for locals Spread of diseases Job opportunities Genetic manipulation May mitigate the starvation issue Fish feed is often made out of wild fish Lower fish prices Poor conditions in fish farms
How does aquaculture pollute water?
It involves the use of large mesh fishing nets to hold the farmed fish, and there is no way to prevent waste from escaping into the water This waste can contain antibiotics, pesticides and fish feces which pollutes the open water and makes it unsafe for human drinking, recreational use, and for other wildlife
What are the disadvantages of commercial fishing?
Commercial capture fisheries Overfishing Habitat damage Bycatch of vulnerable species Discards Fish feed Pollution Parasites and the spread of disease Escapees impacting wild fish populations
What are the disadvantages of integrated farming?
Limitations of Integrated Farming System The need to provide for some measure of food security The need to use the resources of soils, climate, etc to provide employment and economic activity
What is the difference between fish and aquaculture?
Distinction between fishing and aquaculture Fishing is the harvesting of already existing populations of fish and other aquatic animals (Seaweed harvesting is a separate activity) Aquaculture is the purposeful cultivation and subsequent harvesting of both freshwater and marine aquatic plants and animals
How does aquaculture affect the environment?
Environmental effects include health risks to farm workers from water-borne diseases such as schistosomiasis and salinization/acidification of soils and aquifers It is also possible that heavy metals from livestock feeds in integrated aquaculture can accumulate in fish and pond sediments
How does fish farming harm the local ecosystem?
Eutrophication is one of the biggest threats, causing algal blooms and affecting ecosystems, including fish species Faeces and uneaten food pellets from fish farms alter the organic matter in the sediment, which can change the consumption of oxygen and cause local eutrophication
How does aquaculture affect worldwide seafood catch?
But aquaculture can also diminish wild fisheries indirectly by habitat modification, collection of wild seedstock, changes in ocean food webs, introduction of non- native fish species and diseases that harm wild fish popula- tions, and nutrient pollution (Figure 6)
