Description:

Euphausiids (primarily Thysanoessa raschii and T. inermis, hereafter referred to as krill) are a major trophic link in the Eastern Bering Sea (EBS) ecosystem. Krill are a primary prey item for fishes including walleye pollock (Gadus chalcogrammus, hereafter referred to as pollock; Brodeur et al. 2002, Lang et al. 2005), birds including short-tailed shearwaters (Ardenna tenuirostris; Hunt et al. 2002, Nishizawa et al. 2017) and murres (Uria spp.; Decker and Hunt 1996), and fin (Balaenoptera physalus) and humpback (Megaptera novaengliae) whales (Witteveen et al. 2015). Estimates of EBS krill abundance and distribution are utilized in pollock fishery stock assessments (Ianelli et al. 2024), ecosystem-based fishery management efforts (Siddon 2024), and investigations of krill-pollock population dynamics (Ressler et al. 2014, Hunt et al. 2016).
