Continental slope and deep-sea fisheries: implications for a fragile ecosystem
TL;DR: Depletion ofspecies from deep-sea environments that dominate mid to upper trophic levels may have long-term ecological implications, but the risks of reduced stock size and agestructure to population viability, the potential for species replacement, and the impacts on prey and predator populations are not generally known.
Journal ArticleDOI
Molecular structure and composition of fish otoliths
TL;DR: Oxygen and carbon isotope data indicate that the aragonite is formed close to isotopic equilibrium with the sea, which is surprising, because seawater has no direct access to the inner ear where the otolith orginates.

TL;DR: This biomass census and associated maps are vital components of mechanistic deep-sea food web models and global carbon cycling, and as such provide fundamental information that can be incorporated into evidence-based management.
Journal ArticleDOI
Fisheries assessment: what can be learned from interviewing resource users?
Barbara Neis,David C. Schneider,Lawrence F. Felt,Richard L. Haedrich,Johanne Fischer,Jeffrey A. Hutchings +5 more
TL;DR: The range of information available to coastal Newfoundland fishers was identified, to see if it could be quantified, and to explore its potential for reconstructing trends within fisheries, describing ways to access the large reservoir of information held by fishers and the use of several cross-checks to identify consistent patterns.

TL;DR: The authors in this paper show that the combination of very low target population productivity, nonselective fishing gear, economics that favor population liquidation and a very weak regulatory regime makes deep-sea fisheries unsustainable with very few exceptions.
