You like your fish food dish as much as I do ? However ! - Â* The steadily increase in consumer demand for seafood and the concurrent depletion of many wild fish stocks, aquaculture, or "fish-farming," is now used to produce almost half of the world's seafood.1 In fact, aquaculture is currently the fastest growing sector of global food production; as wild fisheries continue to be overexploited and mismanaged, aquaculture production is expected to double by 2050.2 Unfortunately, the industrialization of aquaculture has resulted in many of the same environmental and human health problems currently created by livestock factory <a href="http://www.cheapmonclerjackets.es/nuevo-2010-moncler-mujer-down-abrigo-largo-negro-p-69.html"><strong>Nuevo 2010!

As in the case of industrial livestock production, many of the harmful impacts of industrial aquaculture stem from the concentration of large numbers of animals within small facilities. In addition to polluting aquatic ecosystems with the enormous volume of waste produced by the fish they confine, aquaculture facilities threaten the environment and human health by releasing hazardous substances such as pesticides, antibiotics, and other drugs into the aquatic environment. Industrial aquaculture operations can also harm natural fish populations by introducing diseases and non-native species into the ocean. Pollutants Emitted by Aquaculture Facilities Open water industrial aquaculture facilities typically confine fish within cages or netpens, which allow fish waste, uneaten feed, chemicals, pharmaceuticals, and other pollutants to pass directly into the surrounding water. Fish Feces.As in the case of livestock manure, when large quantities of fish feces enter an aquatic ecosystem, nutrient levels in the water increase. As described in the Environmental Impacts section, the influx of excess nutrients induces algal growth, and can ultimately lead to eutrophication and the reduction of aquatic biodiversity.3 Uneaten FeedThe constant release of uneaten feed causes similar problems; when feed accumulates on the seafloor, it is eventually decomposed by bacteria, which consume oxygen dissolved in the water and can thus create hypoxic "dead zones" below aquaculture facilities.4 The environmental damage caused by fish feces and uneaten feed is particularly severe in enclosed waters with low water exchange rates (ex. lakes, slow-moving rivers, and shallow bays). Pesticides and Pharmaceuticals.In attempt to prevent disease and epidemics of parasites, industrial aquaculture operations use large quantities of drugs, pesticides, and other chemicals. Although the environmental and human health impacts of many of these substances are not well understood, their use is poorly regulated, reporting requirements are insufficient, and federal oversight is inadequate.5 While some chemicals threaten consumers' health by leaving harmful residues in fish, drugs and pesticides can also wreak havoc on the environment since many are toxic to aquatic plants and animals.6,7 For more information, read Food & Water Watch's detailed analysis, Misuse of AntibioticsWhen thousands of fish are confined in a small space, it's easy for disease to spread quickly. Often, industrial aquaculture facilities address this problem by utilizing the same irresponsible antibiotics practices as industrial livestock operations; rather than reducing the density of fish, fish farms continuously administer subtherapeutic doses of antibiotics. This promotes the proliferation of antibiotic-resistant bacteria, which can infect humans.8 The problem is exacerbated by cages <a href="http://www.cheapsuprashoesonline.com/supra-038-skytop-shoes-black-silver-and-red-p-19.html"><strong>supra 038 skytop shoes black silver and red</strong></a> and netpens allowing antibiotics and antibiotic-resistant bacteria to pass freely into surrounding waters. Escapees and BiodiversityAquaculture facilities also threaten natural ecosystems by facilitating the introduction of nonnative marine species (or domesticated varieties of native species) into the surrounding environment. As a result of net damage from storms, industrial accidents, and attempts by marine mammals to catch farmed fish, many aquaculture facilities release substantial numbers of fish into the environment. For instance, the David Suzuki Foundation estimates that in British Columbia, an average of 90,000 farmed salmon escaped each year between 1990 and 2000.9 Fish that escape from aquaculture facilities pose a significant threat to the viability of existing wild populations – particularly to sensitive populations that have already suffered from overfishing or habitat loss. While nonnative fish species threaten native populations by competing for food and habitat, farmed varieties of native species also pose an environmental threat; after having escaped from pens, farmed fish may breed with their wild counterparts, thereby introducing farmed genetic traits into the gene pool of wild populations. This can dramatically reduce the genetic diversity of the given species in a short period of time.10 google_ad_channel = “7940249670, ” + AB_cat_channel + AB_unit_channel; google_language = “en”; google_ad_region = ‘test’; Related posts:After the lifting of water pollution in Harbin Public Jiang fish aquarium business back on track – Water pollution Bioponica Incubator – Raising Fish Food from Waste.
