TL;DR: It is strongly recommended to move from the scientific description of the association to specific experimental studies aimed at identifying ethological processes to provide a better understanding of the dynamics of associative behaviour of pelagic species, which in turn would permit better stock assessment and fishery management.

TL;DR: The horizontal and vertical movements of large bigeye tuna captured in the south Pacific Ocean (French Polynesia) were determined using pressure-sensitive ultrasonic transmitters using the first observations on the role of body size in the vertical behavior ofbigeye tuna.

TL;DR: It is concluded that pelagic sharks have limited spatial refuge from current levels of fishing effort in marine areas beyond national jurisdictions (the high seas), demonstrating an urgent need for conservation and management measures at high-seas hotspots of shark space use.

TL;DR: It is shown that catching juvenile tuna around FADs does not necessarily result in overfishing of stocks, although more selective fishing techniques would likely help obtain higher yield and encourage RFMOs to expand and improve their FAD management plans.

TL;DR: An elementary model of animal aggregation is presented and the group-size distributions resulting from this model are truncated power laws.
