Aquaculture technology is varied with design and development requiring knowledge of mechanical, biological and environmental systems along with material engineering and instrumentation. [4] Furthermore, engineering techniques often involve solutions borrowed from wastewater treatment , fisheries, and traditional agriculture.
The growth rate of worldwide aquaculture has been sustained and rapid, averaging about 8% per year for over 30 years, while the take from wild fisheries has been essentially flat for the last decade. The aquaculture market reached $86 billion [63] in 2009. [64] Aquaculture is an especially important economic activity in China.
A small aquaculture industry in the US Midwest contributes about 90,800 kg (200,200 lb) of yellow perch annually, but the aquaculture is not expanding rapidly. [4] The yellow perch is absolutely crucial to the survival of the walleye and largemouth bass in its range. [ 4 ]
A number of countries have created their own national standards and certifying bodies for organic aquaculture. While there is not simply one international organic aquaculture standardization process, one of the largest certification organizations is the Global Trust, [9] which delivers assessments and certifications to match the highest quality organic aquaculture standards.
Aquaculture not only impacts the fish on the farm, but it also influences other species, which in return are attracted to or repelled by the farms. [79] Mobile fauna, such as crustaceans, fish, birds, and marine mammals, interact with the process of aquaculture, but the long-term or ecological effects as a result of these interactions is still ...
Raising fish in cages in a lake in a relatively undeveloped environment. Urban aquaculture employs water-based systems, the most common, which mostly use cages and pens; land-based systems, which make use of ponds, tanks and raceways; recirculating systems are usually high control enclosed systems, [clarification needed] whereas irrigation is used for livestock fish.
