OECKS AWASH - 61 trout Aquaculture, a promisingindustry? A bout seven yea rs ago . the Upper Trinity South Development Association constructed a trout farm at Hopeall . It 's the only one in Newfoundland. The Association has been at tempting to lease the farm to private enterprise. We spoke to the present operator. Leon ard Lahey. " This farm has two separate stocks," says Leonard. "Your brood stock and your Iry that you feed.up and sell . This brood stock was brought in from Ontario as fingerlings. but it takes two or three years to get brood stock up to size. By then they are four or five pounds. "The harvest is a two-year cycle. We inseminate our own eggs using two or more males for each female to make sure they are fer tilized. The problem is to make sure the female has come to peak. If you are a little early or late your yield drops off. "Once the fry have grown to fingerlings (average 6 in.), we put them in large cages (20 x 20 x 12 It.) and transfer them to Scotch Pond at Green Harbour. The water there is brackish, slightly salty, which is supposed to help the trout's growth. But the move is also stressful and quite a few have died . I'm hoping to change that. By the time they are two years old they average a pound and a quarter. Then we sell them. You may have seen trout being sold by the waterfront inSt. John's . They are from thi s farm." Leonard shows us around the farm , mostly a series of large buildings containing concrete raceways fiIJed with rushing water, trout , and large tanks containing fry. "You have to have a good supply of water. We have the river dammed up and a couple of 6-inch pipes bringing in water. :TROUT Leonard Lahey FARM: Chlorinated water near citie s would beno good, but most Newfoundland water is OK. Temperature is important and ideall y it should be around 15° C. for rainbow trout. If it goes above ia-C. for extended periods you are in trouble because it diminishes the effective oxygen level. " This particular fish hatchery is large. Leonard does not think it is necessarily a model to copy, especially not for a small family operation which is how most Rambow Trout Canadian and Norwegian trout farms operate. ..A lot of the operation can be built using fairly ordinary building techniques . The raceways are concrete, but some people put in plastic liners to save wear and tear on the fish fins. In a family operation, it might be better to buy fish from hatchery when they are 5 or 6 inches long and not bother with a brood stock. "It's also a question of scale. You either have to be large, get a couple or hundred thousand pounds of finished product a year, or aim at something much smaller. I'm looking for 50,000-60,000 pounds a year. Providing I can keep my costs in line, I should do all right. Fish food is one of the biggest expenses. We use fresh male caplin, caplin meal with flour as a binder, and vitamin and mineral additives. It costs approximately GO¢: a pound and it takes three pounds to produce a pound of product. Last year trout sold for $2.50lb. small, $2.70medium, and $2.90 large." Leonard, 43, is from St. John's although his father was from South Dildo. He and his wife Linda moved back in 1970. Linda does the bookkeeping and also operates the fann's fish-outpond. Fishermen pay $2 to fish at the pond for two hours or six troutwhichever comes first - and they pay $2.50a lb. for what they catch. Havtng the only trout farm in Newfoundland (although another is being built at Bay d'Espoir, mainly for salmon) makes Leonard something of a pioneer. Fortunately he has done a fair amount of background research and has a number of fresh ideas. Perhaps aquaculture, as it is called , will become an important industry in the future.
