Regulation Changes

if a fish that has a 4 year life span is described as catchable at 1 and 1/2 years old and has a plus 50% mortality rate
how would 90% of them live to be generally 4 years old?
#fuzzy math

I misspoke using "old age" should have said natural causes, the point is that anglers at a very popular high pressure fishery with a lot of catch and release have a minimal effect on fish mortality.
