FISH STOCKING By: John Capyk Conservation Officer Sport fishermaen often ask why the Minis-- try of Natural Resources does not stock more lakes, or why we do not stock certain lakes in which they are having only limited success | The reasons are many and we will try to exp~- lain a few of them. ; Before a lake is stocked a survey is car- ried out to determine it's area, depth, chem- ical characteristics, spawnings sites, etc. At the same time several nets are set in the lake to determine fish species and population levels. Once this is completed the lake can 1) A "put and take" lake in which there are no suitable spawning sites for the desired species, but that will be able to support a population of the stocked species. A lake that is suitable for certain spe- cies but that at present, contains undes- irable species which would make stocking unsuccessful. Lake Superior with the lam- prey reducing the lake trout population would fall in this category. Undesirable species such as lamprey must be eliminated or reduced drastically before such a lake can be restored to it's former level of productivity. : Lakes that are suitable for the species tc be stocked, with adequate spawning areas, food species, and other non-competitive species. After stocking, such a lake should develop a self sustaining popula- tion of the introduced species. Once we have evaluated the biological as- pects of fish stocking, we then must consider a set of non-biological criteria, such as public demand, accessibility of lakes, and 3) Most fishermen want relatively easy access, so there is always a greater demand for stock- ing accessible lakes than for the more remote lakes. Lakes to be stocked must have public access. Lakes surrounded by private property without public access are not considered for stocking. Most fish species are stocked eith- er as fingerlings or yearlings from Ontario hatcheries. Sometimes disease will strike the brood- stock of a hatchery and deplete the main source of eggs. This has happened recently at the Dorion fish hatchery. Because of the decontamination procedures required we can- not expect to obtain fish from Dorion until 1978 or 1979.

If conditions were suitable the population would likely be at a higher le- vel. Any fish stocked will be affected by the same agency which prevented the original pop- 'ulation from reaching a high population level, for example insufficient food, competition from other species, inadequate spawning sites, excessive predation, or unfavourable water tem- peratures. The Ministry endesvouts to 'stock as many lakes as possible within the framéwork of con- straints described here.
