TAS Country : July 21st 2011
10 Tasmanian Country Friday, July 22, 2011 News HATCHING A BUSINESS: Saltas assistant manager John Ramsden. Pictures: JENNIFER CRAWLEY Taking stock in a fishy undertaking HARDENED: John Ramsden with hatchery staff Steve Arthur, Brendan McLean and Chris Richards. FISH FARMING: The hatchery tanks, right, and eggs incubating at Saltas's Wayatinah hatchery, far right. JENNIFER CRAWLEY JOHN Ramsden says only Tasmanians can hack the cold at the Saltas Wayatin- ah hatchery. ''It's hot in summer and cold in winter time,'' said Mr Ramsden, the assistant manager at the hatchery. ''Tasmanians make the best workers, they can handle the weather.'' The Saltas hatchery and a second sister hatchery at the Florentine are owned by the Tasmanian Govern- ment in partnership with salmon companies like Tassal and Huon Aquacul- ture. Saltas is a big employer of local people in an iso- lated rural area where jobs are sparse. Most of Saltas's 33 staff live at the former Hydro village of Wayatinah, a two-minute drive away. There are 30 million eggs incubating at Wayatinah. The eggs are stripped from large fish or broodstock and broodstock can weigh up to 15kg. A technique called shock-and-pick is used to separate the bright orange live eggs from dead ones, which are white. The eggs hatch little fish born with their own food pouches, which they feed off for 3½ months. The fish grow to 20g before moving to outside tanks. There are 12 hatching tanks and 47 on-growing tanks at Wayatinah, and 12 hatching tanks and 32 on- growing tanks at the Florentine. About 2.7 million smolt, 10 to 12cm long and weigh- ing between 100 and 150g graduate each year from Wayatinah into fish farms around Tasmania. Eggs are also trans- ported to fish companies for growing. Mr Ramsden was about to transport some to Tassal at Huonville: ''I've got a million eggs in the back of my ute at the moment,'' he said. Mr Ramsden is a gradu- ate of the Australian Mar- ine College in Launceston. There is a direct pathway for AMC graduates to com- panies like Saltas, he said.
