Hatchery succeeds in first spawning of ballan wrasse A remote location is not enough on its own. While Selonda Aquaculture’s hatchery in Managouli, Greece, is remotely located in a sparsely populated area, it still features security cameras, motion-activated lights, barbed-wire fencing and is staffed 24 hours a day.
Acts of vandalism spark security discussion
The importance of adopting security measures and protecting your investment BY MATT JONES
T
he last several months have seen a variety of vandalism incidents at hatcheries around the world that led to the loss of fish and related capital. While it varies from case to case whether these incidents appear to have been politically motivated, specifically targeted or are merely random acts of vandalism, they do have some hatchery operators talking about their security measures and what is required to prevent such incidents from occurring in the future.

One of the most important things to consider regarding level of security is the location of the facility. In many cases, hatcheries are found in areas where their very location acts as a form of deterrence. Chris Matteo, owner of North Carolina’s Chadwick Creek Oysters, says his facility is within the area closed off by a private 7,000-acre duck-hunting club, making it an ideally remote location.

New shellfish hatchery in Western Australia produces first batch of rock oyster spat

fforts to culture ballan wrasse (Labrus bergylta) have reached a major milestone with the first spawning of the farmed fish in captivity. The achievement brings the Machrihanish wrasse hatchery – a joint venture between Marine Harvest and Scottish Sea Farms – closer to its goal of supplying enough of the sea-lice-eating fish to service the companies’ salmon farms in Scotland. “The wrasse we produce here from our broodstock farms will go to their farms. Hopefully any surplus can be sold to third parties,” hatchery manager Paul Featherstone tells Hatchery International. The larger aquaculture industry could potentially benefit from the research, says Featherstone. “The research we have done here is for everybody. We have close links with Norway and other hatcheries in Scotland and the information can be disseminated all around the industry. It is a joint industry project and we welcome the opportunity, if need be, to supply larvae to hatcheries.” Wild ballan wrasse has been used in salmon farms in Scotland for years as a non-chemical way of controlling sea lice infestations. “Obviously, that is not sustainable in the long run. I don’t think it can meet the needs of the expanding salmon industry, that’s why Marine Harvest decided to look at the possibility of farming the ballan wrasse,” says Featherstone.

quaculture trials in the Pilbara, Kimberley, Abrolhos Islands and Cockburn Sound will be the beneficiaries of the first consignment of about 500,000 rock oyster (Saccostrea glomerata) spat, grown at the State Government’s new Albany Shellfish Hatchery. The new state-of-the-art hatchery is supporting the growth and development of commercial shellfish farming in Western Australia, as well as creating and supporting WA jobs, a statement from the Government of Western Australia stated.
