Funded Project #3 - Culture Technology of Walleye


(funded project 3)

Description

The third Walleye Funded Project - Chaired by Bob Summerfelt  

Objectives:

  1. Develop baseline information on the mechanisms regulating the natural reproductive cycle of wild and pond-held walleye by characterizing seasonal changes in hormone titers and gonadal histology--Characterization of the natural reproductive cycle.
  2. Develop an index to the abundance of clam shrimp eggs (seed) in pond soil, describe effects of calm shrimp abundance on the ecology of culture ponds (turbidity, algae , zooplankton), and evaluate clam shrimp-zooplankton-fish production interrelationships.
  3. Determine the etiology of non-inflation of the gas bladder in intensively cultured walleye fry.
