The Freshwater Fisheries Society of BC (FFSBC) aims to stock fish that are healthy and enjoyable for a variety of angler types. While there is currently little quantitative knowledge on the catchability of the various rainbow trout strains, attracting new anglers and providing a satisfactory product for current anglers is a primary goal of the FFSBC.
Studying Fish Survivability
Despite the fact that catch and release fishing has become more and more popular over the years, the survivability of these fish is still being evaluated. A recent project on Roche Lake looked at the stress response and mortality of catch and release Pennask 2N (reproductive) and AF3N (sterile) fish. Initial data suggests there is a difference in mortality between the Pennask 2N (0-26% mortality) and AF3N fish (17-33% mortality), with Pennask 2N having higher survival rates. We do not know if this is true for the other strains we stock (i.e. Blackwater, Fraser Valley, Gerrard) or how environmental factors affect mortality (e.g. temperature).
To effectively offer satisfactory products to anglers with different abilities and expectations, the catchability and survivability of FFSBC stocks needs to be assessed. A balance between survival, growth, and aggressiveness is desired for trophy and above average fishing.
