The movements, , and lighting of the camera are all controlled by the operator whc sits comfortably in the boat on the leike surface and is able to seethe bottom of the lake as if he was actually stand- ind on it. So far tests have been conducted with this unique device down to depths of 100 feet of water. Two limnologists of the Canadian Wildlife Service, Department of Resources and Development, who are making the bio- logical observations with this unit, have been able to see in great detail the struc- ture of the lake bottom. They have exam- ined the extent of natural shelters for fish and have observed and recorded the presence of various forms of natural food for game fish, seen swimming and moving in front of the camera. Actual specimens of the fish population have been seen as they appear in their natural habitat and as they swim in search of food or a place to spawn. The tests in Banff National Park will continue for some time and the limnologists hope to be able to settle many other prob- lems concerning the management of game fish by the time the first tests with underwater television are completed. â¢K- 4;- * â );â *. artist's conception of equipment for under- water TELEVISION NEWFOUNDLAND FIRM TO TRY LATEST EURO- PEAN FISHING EQUIPMENT; Fishing equip- ment, entirely new to Newfoundland, will soon be brought from Europe by a large St. John's firm, according to a September 19 dispatch by the American Consulate at St John's.
