An Analysis of Rainbow Trout (Onchorynchus mykiss) Production in the Kettle River System in South Central B.C. Sebastian, Dale

Abstract: A fisheries investigation was conducted on the Kettle River upstream of Midway to assess habitat capability and the stock status of resident rainbow trout. Juvenile and adult populations were assessed using a combination of electrofishing and snorkelling during late summer of 1987 and 1988. The abundance of fry was extremely low in the mainstem (0-7 fish/100 m2), while parr abundance appeared to be reasonable at sites with adequate cover (5-14 fish/100 m2). Densities of catchable size fish were consistently low during both years, except for in the West Kettle River during 1987. The absence of older age classes indicates a problem with overharvesting. Below average summer flows during both study years reduced the proportion of suitable habitat for catchable size fish.
