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.
