MSI: Fish, Energy, Diet, Zooplankton (FEDZ)
Research in the FEDZ Lab supports Marine Salmon Interactions 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.
Sample processing activities:
- Fish identification, measuring, weighing, oven drying; extraction of: otoliths, stomachs, scales, and coded-wire tags
- Energy density determination by calorimetry
- Diet by stomach content analysis and microscopic identification of digested prey
- Zooplankton identification and enumeration by species and stage; community composition, standing stock, and density
