Aquaculture - National Geographic on habitats, restoring marine ecosystems and allowing populations to recover. If you continue to use this site we will assume that you are happy with it. Lets dive into discussing some of the disadvantages of aquaculture. It is therefore crucial that we protect those species so that they are able to recover in the long run. Farm-raised fish arent guaranteed to be as nutritious as wild-caught fish. Fish are a very high source of proteins and have great nutritional value. Another downside of aquaculture is that fish farms often use fishes that have been genetically modified in order to ensure fast growth and a certain resistance against diseases. Declaring marine protected areas could potentially limit the impact on habitats, restoring marine ecosystems and allowing populations to recover. The fishing industry is always under great pressure to continuously supply wild marine life for human consumption. Depending on the kinds of fish a farmer wants to raise, start-up prices can be very low. The World Resources Institute estimates that nearly half the land now used for shrimp ponds in Thailand was formerly used for rice paddies; in addition, water diversion for shrimp ponds has lowered groundwater levels noticeably in some coastal areas.. Types of Fish Farms . Please check your email for further instructions. Polyculture farming is an agricultural method of planting multiple crops in the same field. The idea behind fish farming is to raise fish that can then be sold as food rather than counting on fishers to supply the entire worlds population with wild-caught seafood. Fishermen are usually at the lowest of income classes. After they grow and it becomes feasible, these species are released into the wild. This takes away your choice as a consumer and concentrates control and power over how the industry is run. Not only can this pose a risk to wild marine life, but it may also harm people who share the same water supply. The main environmental complaints regarding farmed fish center around water pollution, disease and species escape. While farmed fish may grow faster and larger, wild-caught species are still more nutritious. Thus, it may not be a good idea to use those growth hormones in aquaculture. However, there is increased competition in lakes and rivers for other resources like food. Hence, fish farming may also be a suitable tool to mitigate the overfishing problem and to protect our global fish stocks.

In turn, if those fishes carry certain diseases, the infection of just a few fishes in fish farms may lead to the infection of large numbers of wild fishes. Understanding The Net Cage Systems with Fish Farming Fish are low in fat but high in protein compared to land animals, so the amount of useful food per acre produced by a fish . New policies also seek to allow habitat restoration, by limiting the area and scope of fishing. @media(min-width:0px){#div-gpt-ad-environmental_conscience_com-large-leaderboard-2-0-asloaded{max-width:300px!important;max-height:250px!important}}if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[300,250],'environmental_conscience_com-large-leaderboard-2','ezslot_7',146,'0','0'])};__ez_fad_position('div-gpt-ad-environmental_conscience_com-large-leaderboard-2-0');Moreover, fewer fishing boats also imply fewer oil spills, which will further improve water quality and therefore protect the natural habitats of many aquatic organisms. Because there are now a variety of different techniques used in fish farming, it can be difficult to make sweeping evaluations of the entire industry. While some companies are looking for innovative waste to manage contaminated water, the majority of operations leach toxic pollution into open waters, including disease, pesticides and pharmaceuticals. One of the biggest issues with farmed fish, environmental waste, may also be an advantage. Similar to factory farming in the meat production process, fish farming can also be considered to be quite unnatural since fishes will not grow up in a natural environment. 6 Pros and Cons of Fish Farming | APECSEC.org This means fishing industry can use the space and save these areas from other industries and developmental work, which usually result in water pollution.

The general public is also quite skeptic when it comes to fishes from aquaculture. The impact of the fish farm depends heavily on the species being farmed. This has been a great initiative that recycles nutrients in sewerage as well as reduces water filtration costs. Hence, frequent testing should be done to prevent any sort of parasites and diseases. Moreover, the use of antibiotics may also harm the living conditions of those fishes, since they would not be exposed to antibiotics in the ocean and antibiotics cannot be considered to be part of the natural nutrition of fishes. International, regional, and local agencies are all involved in the effort, as are agencies concerned with animal welfare, the environment, and food resource management. @media(min-width:0px){#div-gpt-ad-environmental_conscience_com-mobile-leaderboard-1-0-asloaded{max-width:250px!important;max-height:250px!important}}if(typeof ez_ad_units!='undefined'){ez_ad_units.push([[250,250],'environmental_conscience_com-mobile-leaderboard-1','ezslot_15',195,'0','0'])};__ez_fad_position('div-gpt-ad-environmental_conscience_com-mobile-leaderboard-1-0'); Studies have shown that in fish farming, growth hormones are used on a frequent basis in order to speed up the growth of fishes and therefore to maximize the profits of those fish farms. Innovations in technology are helping fish farms reuse and remove water, often through recirculatory aquaponic systems that use microbes to clean the water. Again, this largely depends on the practices of the farm where the fish were raised. Some of these well talk about in disadvantages of Aquaculture. Thus, through the use of aquaculture, a stable supply of fish can be assured, which may be quite important, especially in areas where the local population relies on this fish supply in order to survive. For example, the state of Maine is investing in training institutions and educational resources to support the next wave of seafood employees. Industrial ocean fish farming sometimes referred to as open ocean or marine aquaculture is the mass breeding, rearing, and harvesting of finfish in areas of the ocean in underwater nets, pods and cages.
