Charges

The following are the charges to the WTG for the 2010-2011 work year:

1. Maintain and update centralized time series of datasets required for population models and assessment including;
   • a. Tagging and population indices (abundance, growth, maturity)
   • b. Fishing harvest and effort by grid
2. Improve existing population models to produce the most scientifically defensible and reliable method for estimating and forecasting abundance, recruitment, and mortality. Continue to explore data pooling, catchability blocks, lambdas, and alternate selectivities to improve the existing model.
   
3. Report Recommended Allowable Harvest (RAH) levels for 2011.
4. Review jaw and PIT tagging study results and provide guidance/recommendations for future tagging strategies to LEC.
5. Assist Habitat Task group with the identification and collection of habitat metrics for the purpose of re-examining the extent of suitable adult walleye habitat in Lake Erie.
6. Assist the STC with completion of the five year review of the Walleye Management Plan.
