TL;DR: In this paper , the authors provided a biomass estimate for Antarctic krill (Euphausia superba) in the eastern sector of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) Division 58.2 (55°E to 80°E; area = 775,732 km2).
Using eDNA and SCUBA surveys for detection and monitoring of a threatened marine cryptic fish
Tyson Bessell,Sharon A. Appleyard,Rick D. Stuart-Smith,Olivia J. Johnson,Scott D. Ling,Freddie J. Heather,Tim P. Lynch,Neville S. Barrett,Jemina Stuart-Smith +8 more
TL;DR: In this article , a sampling strategy was designed using a combination of environmental DNA (eDNA) and structured underwater scuba surveys of life-like 3D-printed handfish replicas to estimate detectability and ultimately determine whether current population monitoring is adequately covering the remaining habitat occupied by the species.

Population parameters and conservation implications for one of the world's rarest marine fishes, the red handfish (Thymichthys politus).
Tyson Bessell,Rick D Stuart-Smith,Olivia J. Johnson,Neville S Barrett,Tim P Lynch,Andrew J Trotter,Jemina Stuart-Smith +6 more
TL;DR: The first empirical population size estimates of red handfish are provided and the urgent need for ex situ captive breeding to bolster numbers in the wild and maintain captive insurance populations is highlighted to protect vital habitat to safeguard the species' ongoing survival in the wild.
