A study by Scandinavian scientists found that culling prey fish populations can be an effective strategy for helping restore threatened predator fish stocks.
Notes on verification
Confirmed by the original peer-reviewed Science paper (Persson et al. 2007) and corroborated by independent science journalism (Scientific American). Study design and findings match claim accurately; later research shows real-world complexity but doesn't contradict this specific study. [tier=gold indep_score=0.983 clusters=3 claim_tier=notable]
