Ocean governance meets polar stewardship in the krill management frontier
Antarctic krill sits at the intersection of two evolving legal regimes, and the tension between them demands attention. CCAMLR has managed this keystone species as a fishery commodity since 1982, but the new BBNJ Agreement classifies krill differently, as a marine genetic resource with distinct benefit-sharing obligations. This study's conclusion is practical: a non-monetary approach that leverages CCAMLR's existing observation programs offers the clearest path forward.
Validating Northern Krill as a Calibrated Source of Ocean Protein
Northern krill (*Meganyctiphanes norvegica*) remains a largely uncalibrated source of ocean protein, despite its ecological prevalence. Our systematic review, conducted to PRISMA 2020 standards, reveals critical knowledge gaps: insufficient long-term population studies, incomparable biomass estimates, and a lack of toxicity data on protein concentrates. The constraint to sustainable use is not the processing chemistry, but responsible biomass access. Understanding drives protection.

Antarctic Krill Reproduction Linked to Deep-Sea Hydrothermal Vent Activity
New research links Antarctic krill reproduction to deep-sea hydrothermal vent activity, and it changes how we read the Southern Ocean. The study, published in *Communications Biology*, suggests that vent-driven nutrient cycles may influence krill spawning patterns in ways surface observations alone cannot capture. That is a meaningful step toward integrated ocean intelligence, where biological and geological data meet.
