Sharks are the preferred scraping surface for large pelagic fishes

Sharks are the preferred scraping surface for large pelagic fishes: Possible implications for parasite removal and fitness in a changing ocean Christopher D. H. Thompson, Jessica J. Meeuwig ABSTRACT: Mutualistic and commensal interactions can have significant positive impacts on animal fitness and survival. However, behavioural interactions between pelagic animals living in offshore oceanic environments are

Effects of Altered Stock Assessment Frequency on the Management of a Large Coastal Shark

Effects of Altered Stock Assessment Frequency on the Management of a Large Coastal Shark Cassidy D. Peterson, Michael J. Wilberg, Enric Cortés, Dean L. Courtney, Robert J. Latour ABSTRACT: Stock assessments are particularly resource-intensive processes. Demand for assessments typically exceeds capacity, stimulating interest in reducing stock assessment frequency for suitable species. Species with slow population
