What are the Disadvantages of Fish Farming?

What is Aquascaping? Also known as fish farming, Aquascaping is a form of agriculture that deals with rearing of fish for consumption and commercial purposes. These fish farms can be located in indoor tanks, freshwater lakes or in saltwater cages. But Aquascaping isn’t at all rosy as people want it to be. There are disadvantages to the art, too.

Keeping fish in an enclosed proximity increases the chances of diseases. If one of the fish contracts a contagious virus then, it will easily transfer to the other fish in the farm. Fish are also infested with parasites. According to the This Website , salmon are susceptible to outbreak s of sea lice.

Diseases

Many farmed fish–such as salmon, bass and cod–are carnivorous. They require large amounts of protein to sustain their fast growth and energy requirements. This protein is often derived from smaller bait fish ground up into pellets. Yet it takes five pounds of fish-meal to create a pound of salmon, according to the Woods Institute for the Environment at Stanford University. This is an inefficient conversion rate.

Fish farmers should avoid rearing fish in enclosed proximities. Thus if a fish contracts a contagious virus, it won’t spread easily to the other fish in the firm.

Biz Fluent states that there has been an increasing concern with fish farming practices. People are not certain of which food sources are used to feed the farmed fish. According to EnvironmentalExpert.com, it has been a practice not yet determined to be a sustainable. We are also not sure if this will also strain wild fish stock.

Sustainability is an Issue

One of the disadvantages of fish farming is that most farms are put into natural lakes or saltwater coastal regions where local fish exist. The problem occurs when these farmed fish negatively impact the area by introducing toxic micro organisms which then infect local fish and put them at risk of being killed off. It is not widely known among scientists or fish farmers what the true impact of these fish farms will be on the local ecosystem, especially when the fish being introduced are not native to the area.

Some consumers in the United States found out that highly recommended salmon (a fish they had been advised to several times a week) was tainted with mercury and PCB’s. There are simply a lot of questions to ask on this.

Most of the concerns that surround fish arise from the crowding together of thousands of fish in their environment. Research shows that chemical used to treat the pests and disease that afflict fish in these concentrated number affect the entire ecosystem.

Growing Concern on Fish Farming

Fish in captivity must be fed. Some species are herbivores or omnivores; species like shrimp and salmon are carnivorous and must be fed on other fish. According to Time magazine, “It takes a lot of input, in the form of other, lesser fish — also known as ‘reduction’ or ‘trash’ fish — to produce the kind of fish we prefer to eat directly.

In many areas water is heavily polluted from agricultural runoffs, industries and sewages, notably China. It is a great concern when it comes to eating fish raised in such environments. 

Conclusion

Fish farming, whether as an art in Aquascaping or economic activity, has been practiced for hundreds of years. In the world today, fish farming produces a wide variety of both saltwater and freshwater finfish, mollusks and crustaceans. The major challenge of Aquascaping is lack of sufficient water and land.

What are the Benefits of Fish Farming?

What are the Benefits of Fish Farming?

Fish farming is part of the art of Aquascaping. It is also referred to as pisciculture. It involves raising fish in enclosures like fish tanks generally for view or for food. It is the principal form of aquaculture. But what really are the benefits of fish farming?

Fish is a pure source of protein. Experts from World Wide Aquaculture say that a good diet should comprise of proteins and other types of nutrients, which can be found in fish.

Meeting the global demand for protein

It is possible to keep the ecosystem and biodiversity intact in an aquaculture fish farm by following the sustainable methods of fish farming. Some fish farms tend to overpopulate the ponds, which may increase the amount of organic waste produced and growth of some harmful algae.

Eating a fish well prepared is a way among others that can help you acquire nutrients. Eating of fish can greatly improve your health hence building your body.

According to Health Fully, a large number of people rely on fish as their source of protein. This means fish farming has become a more attractive economic activity in this day and age.

Fish Farming Creates Job Opportunities

Fish farming allows for large supplies of fish to be farmed according to demand. Catching fish from the wild may not yield enough product to meet consumer demand and simultaneously keep the natural ecosystem in balance. The Food and Agriculture Organization of the United Nations estimates that by 2030, about 40 million tons of seafood will be necessary to keep up with demand. The ocean’s ability to produce enough fish has diminished over the years, leaving aquaculture as the only method to keep up with this increasing demand.

Fish exportation earns more money per year than any other food commodity. This means that there are still job positions to fill and money to be made.

According to The Balance, Researches made by various institutions indicate that fish farming poses a low risk to the environment which is very true.

Fish Farming and Low Environmental Impact

There are several career opportunities within aquaculture, and most, but not all, will require some kind of degree or advanced training. Aquaculturists can find work with state and federal government agencies, on fish farms, and within academia. To be an aquaculture farmer, on-the-job training is the main requirement.

Fish farming may benefit the environment in various ways. Most of the methods used to rear fish do not pose threat to the environment. The only wrong things being done are pollution and the use of chemicals.

Conclusion

Fish farming has been able to gain momentum due to the high demand of fresh fish- this has been able to put a strain on natural pollutions. It is also cheap since it can be conducted in man-made tanks, which are found commonly in fish hatcheries.
