Recruitment Processes: Larval Population Processes Project

This project works on a variety of topics ranging from larval age and growth studies, mortality estimation, population genetics and juvenile fish ecology.

Larval age and growth studies

The age and growth component of the team studies various aspects of larval and juvenile otoliths (see images) to examine life history parameters of marine fishes such as growth (growth chart), spawning times (hatch date graph), transport (drift map), migration and mortality (mortality graph).

Population genetics

This component works on population structure of pollock (genetic divergence graph) and cod, as well as issues involved in determining parentage of cannibalized atka mackerel eggs and identification of skate species.

Forage fish ecology

This component works on the ecology of forage fishes in the northern Gulf of Alaska, including studies of distribution, feeding and energetics, competition, and growth. Species of interest include capelin, eulachon and walleye pollock. For more information about this study visit the forage fish ecology page.
