What does this research mean for the field?

Biotic factors, specifically stocking rates and predator abundance, are the primary drivers of walleye recruitment in stocked reservoirs, exerting a stronger influence than abiotic factors such as precipitation and winter severity. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Implication

Randomized trial examined factors affecting walleye recruitment in a large reservoir, indicating stocking is key for population recovery.

Key Points

The study aims to determine how abiotic and biotic factors influence walleye recruitment in a stocked reservoir.
Examined walleye recruitment data from standardized fall gill-net surveys (1991-2020).
Used models incorporating abiotic and biotic factors like stocking, predator, and competitor abundance.
Analyzed model performance using Akaike's information criterion (AIC).
Stocking was positively associated with walleye recruitment and had the highest relative variable importance (RVI).
Predator CPUE also positively influenced recruitment and had the second-highest RVI.
Biotic factors explained more variability in recruitment than abiotic factors, indicating the importance of these influences.
