Our objective is to promote sustainable, responsible fish farming, regulated by transparent government and commercial processes. Distinct vertical markings appear on the fish which in the wild act as camouflage for the fish. Fish farming business is a great source of employment. Eggs are incubated at the hatchery in an environment that aims to mimic egg incubation in the wild, for example, by providing substrate in which eggs can nestle and clean water flow providing plenty of oxygen for the eggs to grow. The unconscious fish are then bled to ensure death and immersed in an ice slurry for transport to the processing plant. WWF-Australia today said Tasmania’s salmon producers are making substantial progress towards sustainable aquaculture in Australia, with two of the state’s largest producers, Tassal - who has a partnership with WWF - certified in 2014, and Petuna certified this month by … The FAO of the UN predicts that the world’s population will reach 9.7 billion by 2050, and the demand for food is set to increase by 50%.

The first year of production takes place in controlled freshwater environments, and then the farmed salmon are transported to seawater cages. Salmon have a natural lifespan of between 3 to 8 years. Is the future of Atlantic Salmon farming in Australia at sea, or all ashore? Farming of Atlantic salmon begins on land at the breeding farm where ‘broodstock’ (sexually mature fish) are held in large freshwater ponds or tanks. Once a year, usually in autumn, individual broodstock are anaesthetised by submerging the fish in a water bath containing an anaesthetic agent. At the same time, a physiological change occurs internally which allows the Atlantic salmon to survive in seawater. The first fertilised Atlantic Salmon eggs were purchased from the Gaden hatchery in NSW in 1984, so beginning Tasmania’s Salmon farming industry. In Tasmania, salmon farmers use only female fish in the grow-out phase because the relatively warm seawater temperatures can result in rapid sexual development in male fish which, in turn, results in greater disease susceptibility and poor meat quality. Instead, nets are regularly cleaned in situ to prevent biofoul build-up on the nets affecting oxygen supply to the fish. A range of environmental regulation processes which were in place prior to the EPA taking responsibility for environmental regulation in mid 2016 have now been consolidated into Environmental Licences. This means that if, for example, the water temperature during incubation is 8 degrees, the incubation period is around 56 days. The salmon farming production cycle lasts about 3 years.

In sea pens, the enclosure nets are kept clean to prevent build-up (‘biofouling’) of algae and microorganisms that impede the flow of water which supplies oxygen and removes waste products and other organic matter from the sea pens. barramundi) and eat smaller fish … Salmon farming is significant in Chile, Norway, Scotland, Canada and the Faroe Islands; it is the source for most salmon consumed in the United States and Europe.
