Doesn't answer the question directly, but very interesting info in this doc.
Perch OverviewKey points to your question:
- Perch of similar size school together.
- Males arrive at spawning site before females.
- Males mature faster, 2-3 yrs, and are therefore smaller on average as mature fish.
Many people argue not to keep "large spawner" females. but according to this and the articles I read:
- Females mature 3-4 years
- Average life expectancy is 7yrs, upper range limit is 11yrs.
- Average size reached at 7yrs is 11 inches (tbd feedstock, water body - arguably higher in the great lakes given the higher average size in large bodies).
So those 13-14" hogs are likely near end of life, they may only have a few spawns remaining before natural death. Conversely a healthy 8-11inch fish may have several spawning seasons remaining. Is the net impact any different keeping one of the other size? I dunno, but it's interesting food for thought.
