Non-Game or Rough Fish - In many Ontario waters, there are carp and suckers. They are often referred to as rough or coarse fish. They feed along the bottom of ponds and streams, picking up bits of food with their sucking lips, keeping the waters clean. Commercial Fish - There are a great number of kinds of fish that are taken each year from our larger lakes. Whitefish, Cisco, White Bass, Pickerel, Perch, Lake Trout and Smelt make up the major part of the total catch. Commercial fishermen must obey certain laws concerning the size of nets, fishing areas, and kinds of fish to be taken. A general game fish cannot be taken by commercial fishermen. Restockingour waters: In the 18thcentury, lakesandstreams hadanabundanceoffish. When settlers poured into Southern Ontario, forests were cleared, streams damned, and wetlands drained. Soon stream banks erod­ ed, silt ran into streams, suffocat­ ing fish eggs and young fish. Soon people began to notice there were fewer fish. The need for stocking is deter­ mined by public demand, the natural supply of fish, and public access to waters. Most fish are collected by MNR staff, using various methods. The length, weight, and sex of each fish is recorded, and in some cases, scale samples are taken for use in determining age. Often a sample of flesh is removed from a fish, and sent to the laboratory for further testing. There are many poisons in water that kill varieties of fish, such as mercury, a naturally occurring substance found in rocks, soil, plants and animal matter, as well as in fish; PCB’s, a group of chlorinated organic compounds, the top killer of fish species with a high fat content; Mirex, a chlori­ nated compound used as a pesti­ cide; and DDT, which accumulates in fatty tissue, causing markedly reduced reproduction. Acid rain is everyone’s problem. It affects lakes, rivers, forests and buildings, and can kill fish by attacking the reproductive system, interfering with food chains, and causing metal poisoning. Fish as a resource are useful in many ways: for eating (flesh and caviar); for sport (game fish, commercial fish); and for fertilizer (flower beds, grass, garden.)
