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.
Trout do best in spring water because it keeps a constant temperature, while catfish need a strong flow, about 80 litres per second for every 0.4 hectares of raceway. A backup water supply should be positioned so, if the water supply or pump fails, it can flow by gravity into the start of the raceway. [16]
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.
Physical-chemical quality such as temperature, oxygenation and nutrient conditions; Chemical quality that refers to environmental quality standards for river basin specific pollutants. These standards specify maximum concentrations for specific water pollutants. If even one such concentration is exceeded, the water body will not be classed as ...
The aquaculture or farming of piscivorous fish, like salmon, does not help the problem because they need to eat products from other fish, such as fish meal and fish oil. Studies have shown that salmon farming has major negative impacts on wild salmon, as well as the forage fish that need to be caught to feed them.
According to the FAO, "...a fishery is an activity leading to harvesting of fish.It may involve capture of wild fish or raising of fish through aquaculture." It is typically defined in terms of the "people involved, species or type of fish, area of water or seabed, method of fishing, class of boats, purpose of the activities or a combination of the foregoing features".
Transactions of the American Fisheries Society - features papers on basic fisheries science; North American Journal of Fisheries Management - covers research, experiences and recommendations regarding fisheries management; North American Journal of Aquaculture - coverage of breeding and raising aquatic animals;
Aquaculture Research is a peer-reviewed academic journal on fisheries science and aquaculture published by John Wiley & Sons since 1970. The journal is abstracted and indexed in the Science Citation Index, Scopus, AGRICOLA, Biosis, Food Science & Technology Abstracts, Academic Search Premier, and GEOBASE. [1]
