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:

  1. 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.
  2. 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.
  3. Prepare a Lake Erie Yellow Perch Management Plan.
  4. 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.
