Title: SEA: Somatic and Spawning Energetics of Herring/Pollock 95320-U

Project Year and Number: 1995: 95320-U

Other Fiscal Years and Numbers for this Project: 1998: 98320-U, 1997: 97320-U, 1996: 96320-U

Principal Investigator (PI): AJ Paul (UAF/IMS Seward Marine Ctr)

Managing Agency: ADFG

Assisting Personnel: None

Research Location: All Spill Affected Areas

Restoration Category: Research

Injured Resources Addressed: Commercial Fishing, Pacific Herring

Abstract: This project would focus on the seasonal somatic energy cycles of two important forage fish species in the spill area — Pacific herring and walleye pollock. The project would explore overwinter survival of juvenile herring and herring reproductive biology and provide energetic information to quantify trophic interactions (food webs) involving pollock.

Datasets:
EVOSTC Data Archive: Project examines inter-annual variability in somatic energy content of pelagic forage fish and pink salmon fry. Specific data sets exist to: 1. Describe the inter-annual somatic energy profile of age zero herring relative to geographical location. 2. Examine fall and spring energy stores of juvenile herring from several sites and compare it to fish starved in the laboratory, and fish captured during the winter fast, to describe the role nutritional status plays in over-winter survival. 3. Measure fall and spring somatic energy content of juvenile pollock and make comparisons of their nutritional status to geographical location and that of juvenile herring. 4. Measure the spring somatic energy content of pink salmon fry in different schools and from predator stomachs, so a comparison of their nutritional status vs. likelihood of loss to predation can be made. Reports, ASCII files, Sigma Plot files Availability: Data set will not be completed until 1999. Available to collaborating researchers and managers though the scheduled release of the SEA database, and by publication of journal papers during 1997-2000.
