Abstracts of Fisheries Management Reports, Technical Circulars and Project Reports of the Fisheries Branch Daiva O. Zaldokas & Debra L. Aird B.C. Fisheries Branch, 2204 Main Mall, U.B.C., Vancouver, B.C. V6T 1Z4 Fisheries Technical Circular No. 91 1992 THOMPSON-NICOLA SUB-REGION SOUTHERN INTERIOR REGION Chan, B.M. 1987. Chemical Rehabilitation of the Kane Lakes British Columbia Summary Report. Fisheries Branch, Southern Interior Region. Tech. Rep. The Kane Lakes Rehabilitation Project was carried out between September 30 and October 2, 1986. Bioassay results indicated a concentration of 1.5 mg/1 of Noxfish brand rotenone (15% a.i) was sufficient to eradicate the Redsided Shiner (Richardsonius balteatus) population. In total, 5396 litres of rotenone was applied to the 6 lakes and associated drainage. Post treatment live cage monitoring indicated a complete kill. Water chemistry sampling to determine hydrocarbon and rotenone residue levels is ongoing. Restocking with Brook and Rainbow trout is scheduled for May, 1987. Reopening of the sportfishery is targeted for May, 1988. Chan, B. 1989. Summary Report Deep Lake Rehabilitation Project. Fisheries Branch, Southern Interior Region. Tech. Rep. The Deep lake rehabilitation project was carried out on October 14, 1987. Both Noxfish brand Rotenone and Fintrol brand Antimycin were applied in an attempt to remove an introduced population of Common Goldfish (Carassius auratus). Post treatment live cage monitoring indicated a complete kill. Restocking with Brook Trout (Salvelinus fontinalis) occurred in May, 1988. Growth rates in September, 1988 indicated an adequate size would be achieved for a May, 1989 opening. Cartwright, J.W. 1989. A Guide to Fish Stocking in British Columbia. Fisheries Branch, Southern Interior Region. Tech. Rep. The original "How and Why of Fish Stocking in British Columbia" was prepared in the mid-1960's and was intended as a guide for new staff confronted with the problem of stocking lakes. This document is a revised version of the original, incorporating newly developed appendices of fish sizes and availability to better relect hatchery production capabilities as we move into the 1990's. This "guide" deals with many of the subjective and objective elements which should be considered by regional fisheries staff when considering stocking a new lake, or reviewing past stocking lists or rationales. Discussed are two stocking formulas and the basic modifications to these formulas commonly used to determine how many fish should be stocked. The two basic formulas discussed were originally developed for rainbow trout stocking into small, productive, interior lakes. They should not be used for other species except, perhaps, for brook trout (char) or cutthroat trout in which cases they may provide a useful approximation of numbers needed for initial stocking.
