Yellow Perch Task
Group
The Yellow Perch Task Group (YPTG) consists
of fisheries scientists from state, provincial, federal
and academic agencies conducting research on Lake
Erie. The YPTG is a sub-committee of the Lake Erie
Committee (LEC), appointed by the LEC and addressing
charges from the LEC relevant to yellow perch management
in Lakes Erie and St. Clair and connecting waters.
Charges
The following are the charges to the
YPTG for the 2007-2008 work year:
- Maintain centralized time series of datasets of
data required for population models and assessments,
including:
a) Fishery harvest, effort, age
composition, and biological parameters.
b) Survey indices of juvenile and
adult abundance, size at age, and biological parameters.
c) Examine methods of expressing
recruitment indices; i.e., area-based trawl catch
rates (catch/ha).
d) Standardize approaches within
YPTG and between TPTG/WTG, including q blocks and
selectivity methods.
- Support a sustainable harvest policy by:
a) Examining exploitation strategies.
b) Recommending an allowable harvest
for 2008 for each management unit.
c) Supporting decision/risk analysis
strategies for yellow perch management.
- Prepare a Lake Erie Yellow Perch Management Plan.
- Review different methods for calculation of lambdas
for use in catch-at-age analyses; implement the most
scientifically defensible method for weighting data
sources used in analyses.
