The Fishery Ecology Diet and Zooplankton (FEDZ) program conducts research on marine ecology of juvenile salmon, on stock assessment and enhancement of salmonids and on other fishes in Southeast Alaska and other parts of North Pacific Ocean marine ecosystems. Studies focus on stewardship and management of salmon as keystone indicator species regarding ecosystem fluctuations in support of NOAA Fisheries goals and international obligations including Pacific Salmon Treaty (PST), North Pacific Anadromous Fish Commission (NPAFC), and Global Ocean Ecosystems Dynamics (GLOBEC).

FEDZ Lab research supports studies on the biology, trophic ecology, and bioenergetics of juvenile salmon and associated fishes, along with how they interact in ecosystems during their early marine life history. The goal is to better understand recruitment mechanisms and processes that describe growth and survival of these populations relative to their prey, predators, and potential competitors. Sample processing in the FEDZ lab focuses on measurements of fish size, energy density, and diet and feeding success of juvenile salmon and associated fishes, as well as the abundance and composition of their zooplankton prey fields.

Coded Wire Tags (CWT) are small pieces of magnetized stainless steel wire with a code etched on the surface. Since the late 1960's, CWTs have been the primary means for marking Pacific salmon (Oncorhynchus spp.) for stock assessment, harvest management, and enhancement evaluation. Information on the release, sample, and recovery of all CWT salmonids throughout the Pacific region is available in an on-line coastwide database, the Regional Mark Information System (RMIS). The FEDZ program at ABL is responsible for maintaining several different components of this coastwide CWT database.
