Summary

We examined how marine-derived nutrients (MDN), in the form of spawning Pacific salmon, influenced the nutritional status and delta super(15)N of stream-dwelling fishes. We sampled juvenile coho salmon (Oncorhynchus kisutch) and Dolly Varden (Salvelinus malma) during spring and fall from 11 south-central Alaskan streams that ranged widely in spawning salmon biomass (0.1-4.7 kg.m super(-2)). Growth rate (as indexed by RNA-DNA ratios), energy density, and delta super(15)N enrichment in spring-sampled fishes increased with spawner biomass, indicating the persistence of spawner effects more than 6 months after salmon spawning. Point estimates suggest that spawner effects on nutrition were substantially greater for coho salmon than Dolly [...]
