When haying the return pipes pour the water info the tanks from the top, everything looked rosy. The system was switched on, and tests indicated that a desirable temperature could be maintained continuously throyghout the system, suitable for fish health. IThen the fish were brought and put in the tanks, there was no failure, and the show was on. This is believed to be the first time in Canada, if not in North America, that an exhibit of fish FRANK R.

Essentially the water must be in adequate supply and clean and cool. The novel system now in use by the Department came from an idea developed at the Interna- tional Plowing Match at Lindsay in 1948. At that time the spon- sors of the exhibition advised the Department that water would be piped throughout the fair for drinking and washing purposes. Therefore, the Department decid: |® ed to put on an exhibit of game fish. Within several days of the opening of the fair it was decided that this system would not or could mot be installed. To the Department it looked like the finish of the fish exhibit but with Al Fenwick and Jim Hutcheon on the job they figured how to "turn a corner" so that fish would be displayed, and Jim started on one of his. typical hunts, -soon -com= ing back with the idea of utilizing a mechanical cooling refrigeration unit.

Blakelock Brothers BUILDERS -- CONTRACTORS RANDALL STREET - - IF YOURE PLANNING TO BUILD OAKVILLE had been made and used for sev- eral days using one batch of water. However, the boys in the Fish and Wild Life Division, particu- larly Al Fenwick and Jim Hutch- eon, were not completely satis- amount of dirt date, in an exhibit of longer dur- ation. The problem was to elim- of how those exhibits were Dlac-|inats this dirt, which consisted of fish excreta, and fungus which tiem makes an extremely inter-| formed on the fish, with some of the latter becoming free and clouding the water. Incidentally, this matter of fungus is a "bug bear" of fish hatcheries. The problem tilted the 'scales in the direction of action and a permanent cure, if such were possible, and research started. The ideal was a supply of water free of injurious chemicals, main- tenance of temperature at about 52 degrees, and elimination of fish excreta and fungus. : The problem of fresh water free of chemicals was already solved by bringing it from a re- liable source. The milk cooler refrigeration system looked after the maintenance of the temper- ature. That stripped the problem to filtration and removal of fun- us. Al Fenwick conceived the idea f incorporating into the system tank about the same size as the aquaria which would serve as a filtration plant. plant. "There dre two things to do," he told Jim Hutcheon. "First, rig a mechanical filter to catch the excreta, and second find some] chemical means of killing off the fungus." That was all Jim need- ed. He built the tank, put in a screen ontop of which he spread a layer of crushed Italian marble. That solved the filtration prob- lem. What would kill the fungus? Jim had seen the tiny 2-watt ultra-violet lamps used in toilets to kill germs, and he knew that such lamps were used in hospital operating rooms to kill flies. That was the lead. Working with the Department of Chemistry at the University of Toronto, they advised him that he was on firm ground, and he ended up with two ultra-violet tubes on the inside of the top cover of the tank. However, they discovered then that they 'meed both 25 and 60 ¢yele circuits, this was not a serious problem. After getting the improvised aquaria set up they then experimented in the basement of the Parliament Buildings at Queens Park for some days using live fish in the tanks and the experiments were highly successful. Immediately after the experiments this sys- tem was given its baptism by being put to practical tests In a natural exhibit. It worked. The fungus problem was completely solved, and the excreta removal 99 percent efficient. Never completely satistied, the boys are now trying out a dia- tomacious earth filter, instead of crushed Italian marble. When you read a report like this from O. C. Jennette, it makes you realize just to what lengths the Department will go to see that proper exhibits are put on and the proper precautions are taken in keeping the fish on ex- hibit in excellent condition. When we have someone like that working so hard to give us good fishing, why is it we have a bunch of cheap little chislers working just as hard to destroy fish?
