Default slow growing

The bio's excuse for re-introducing lakers in Touchwood is a poor one.

The following is on the sign of Rock Lake - South of Grande Cache

"The waters of Rock Lake are nutrient-poor, cold and provide a short growing season. Under these conditions, fish grow slowly, and mature later in life. The replacement rate for fish harvested from this water body is very slow"

"Female lake Trout do not begin spawning until they are about 45 cm (18 in.) in length, at anywhere from 6 to 11 years of age. Mature Lake trout grow very slowly, at a rate of about 0.5 cm (less than 1/4 of an in.) per year. Therefore, lake trout 14 to 16 years of age can often be less than 50 (19.5 in.) in length"

"The lake trout population in Rock Lake was over-harvested in the past. A 50 cm minimum-size limit is in place to help the lake trout population recover. The regulation protects female lake trout from harvest until they have spawned at least once."

Just because the conditions for re-introduction are not ideal, doesn't me we should kibosh the re-introduction of Lakers to Touchwood. Re-introduce them, put in a 100% c&r until further notice, and let nature decide if they will become self-sustaining or not.
