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.
