These are the following reasons that affect the industry and make fish farming also a drawback in the economy. 1. It Contributes to the Growing Issue of Water Contamination. As mentioned, fish farms can be made anywhere, where water is easy to be supplied.
There is a Risk of Eating the Supplied Fish from Fish Farms Even fish farms are using pesticides to avoid pest infestations. The fish are also mass treated with drugs in order to prevent sickness and disease. These are chemicals that not only affect the ecosystem, but also consumers health. 3. It Comes With an Environmental Impact
It is a Good Source of Living It provides a very secure and stable way for fisherman to earn a living. It also grants them more time at home, and a longer time frame of which they can harvest fish. 2. Fish Farms can be Made on Coastal Areas and Inland Lakes and Rivers
Over 30% of the natural biomes where commercial fishing takes place have been over-exploited in recent years. Some regions are seeing a 90% loss of some species. As demands for seafood continue to rise, fish farming offers an opportunity to meet that demand without placing more pressure on the natural reserves. 2. it provides a source of income.
Why is fish farming bad for the economy?
1. It Contributes to the Growing Issue of Water Contamination. As mentioned, fish farms can be made anywhere, where water is easy to be supplied.
3. Keeps a Growing Supply of Seafood. Seafood provides many key nutrients and vitamins to the human body. Fish farming brings a more steady supply of seafood into areas that may not normally have this type of access. It also helps to lower the price of seafood.
Fish farming means that large amounts of fish are bred and raised for the sole purpose of being food. This is called aquaculture, which has long been practiced by all types of people. You can find examples of fish farming all through out history, even as early as the Pre-columbian days. The practice spread from one place to another …

What happens if fish farms fail?
Even if they are present there naturally, the sheer number of them that release to the waterways can devastate the region. 2. It can contaminate our food supply.
As demands for seafood continue to rise, fish farming offers an opportunity to meet that demand without placing more pressure on the natural reserves. 2. it provides a source of income. Although fish farming does take away commercial fishing opportunities, it also provides local jobs that typically pay well.
List of the Pros of Fish Farming. 1. It is an effective way to reduce over-exploitation of fish resources. Over 30% of the natural biomes where commercial fishing takes place have been over-exploited in recent years. Some regions are seeing a 90% loss of some species.
Fish farming fits into the industry of aquaculture. The fish are raised in the system in enclosures with the intent that they will one day be sold as a food source. About 50% of the fish that we consume around the world each year are now raised in these artificial environments. Numerous species include tuna, cod, salmon, and halibut.
It is even possible for the waste products from the fish farm to enter the local water supply. 3. It can change the local habitat. Building artificial cages for fish will change the local waterways. Mangroves in Southeast Asia have experienced destruction because of advancing aquaculture efforts.
It can contaminate our food supply. The quality of the seafood we eat is dependent on the health of the water where the marine life lives. Any contaminants in the water can become part of the foods we eat. It is even possible for the waste products from the fish farm to enter the local water supply. 3.
How much of our fish is farmed?
Today, in the developed world, it is thought that around half of all the fish we consume is from farmed sources. Certainly, in a UK supermarket or on a restaurant menu, the vast majority of salmon will be farmed. Wild salmon is much less accessible and comes with a substantial price premium.
These included the escaping of fish, which caused problems when they then bred with wild populations, the polluting of seas and waterways, use of unsustainable fish feed, overuse of drugs to treat health issues in stocks, and the questionable use of chemicals.
As technology and science continue to develop, the ratio of marine ingredients in salmon feed is continually being improved, to help the conversion of wild fish into farmed fish become more efficient. The fact remains that we have a much larger demand for salmon than we do for the small wild fish that go into its feed.
When buying a farmed fish product such as salmon, trout or prawns, it is recommended to buy from a trusted supplier and ask whether it is from a certified source. Some supermarkets have a policy of ensuring all their salmon carries a certification, such as RSPCA Approved.
It is commonly thought that “inland” ponds can offer more sustainable environments for fish to be produced. One of the key factors affecting the sustainability of farmed fish is the feed that’s used. Fish such as salmon naturally feed on smaller fish.
Fish such as salmon naturally feed on smaller fish. Therefore, a large percentage of the feed given to farmed salmon is made up of fish protein and fish oil. These fish components will come from wild fish, so this needs to be from sustainable sources to ensure the farmed salmon is, in turn, sustainable itself.
However, in the developed world this is becoming less and less common. Often some wild berries, mushrooms, or perhaps rabbit or venison might be the only ‘wild’ foods we expect to see on a menu. We accept the fact that our beef, chicken, pork, dairy, fruit, veg, cereals and more all come from farmed sources.
What are the problems with fish farming?
Many of the concerns surrounding fish farming arise from the crowding together of thousands of fish in their artificial environment. Waste products, including feces, uneaten food, and dead fish, are flushed (often untreated) into the surrounding waters where they add to the contamination of the water supply. Also in this effluent are pesticides and veterinary drugs that have been used in an effort to treat the pests and diseases that afflict fish in these concentrated numbers. Such chemicals affect the entire aquatic ecosystem. In many areas, notably China, waters are already heavily polluted from sewage, industry, and agricultural runoff. There are serious questions about the advisability of eating fish raised in such environments. Consumers in the U.S., who had been advised to eat fish several times a week for the health benefits, were dismayed to learn that highly recommended farmed salmon was found to be tainted with mercury and PCB’s.
Environmental impact. Coastal areas worldwide have seen habitat and ecosystem alterations in order to accommodate fish farms. Mangrove forests–complex ecosystems that lined great stretches of the coasts of Thailand, Vietnam, and China, as well as those of other countries—have been destroyed to create shrimp and fish farms …
Fish farming—aquaculture—has been practiced for hundreds of years, from Pre-Columbian fish traps in the Amazon basin to carp ponds on ancient Chinese farms. Today aquaculture produces a wide variety of both freshwater and saltwater fin fish, crustaceans, and mollusks: farmed species include salmon, shrimp, catfish, carp, Arctic char, trout, …
To create 1 kg (2.2 lbs.) of high-protein fishmeal, which is fed to farmed fish (along with fish oil, which also comes from other fish), it takes 4.5 kg (10 lbs.) of smaller pelagic, or open-ocean, fish.”. In an article on bluefin tuna farming published in the San Francisco Chronicle, a seafood wholesaler estimated that it takes 26 pounds …
Pests such as sea lice (tiny crustaceans that prey on fish) proliferate in fish farms and spread out to afflict wild fish. Sea lice are especially damaging to salmon, sometimes eating away the flesh of their heads down to the bone.
Individual fish, often of non-native species, escape from fish farms to compete with native fish for food and habitat resources. Agencies worldwide have called for better management of fish farms, strict enforcement of regulations to protect consumers, more research on sustainable practices, and sharing of information on sound aquacultural …
A staggering 37% of all global seafood is now ground into feed, up from 7.7% in 1948, according to recent research from the UBC Fisheries Centre. Some goes to fish farms and some feeds pigs and poultry. Both are examples of what Francis Moore Lappe called “reverse protein factories,” where the resources far outweigh the product.
