Culture Technology of Walleye #4

Description


The fourth Walleye Funded Project.   Chaired by Jeff Malison  

 


Objectives:


  1. Develop methods for manipulating the annual reproductive cycle of walleye to induce out-of-season spawning.
  2. Measure genetic parameters required for efficient selection on fry and fingerling traits, using pedigreed families.

Culture Technology of Walleye #5

Description


The fifth Walleye Funded Project.  Chaired by Bob Summerfelt


Objectives:


  1. Measure genetic parameters required for efficient combined selection on sub-adult and adult traits, using a pedigreed population of walleye.
  2. Compare performance (survival, growth, feed conversion) of walleye hybrids produced from different parental stocks reared under intensive and the tandem extensive-intensive culture systems.

Characterization of Aquaculture Effluents from Four Types of Production Systems

Description


The first Wastes/Effluents Funded Project.  Chaired by Fred Binkowski.


Objectives:


  1. Characterize aquaculture effluents from four types of aquaculture productions systems: pond culture; flow-through culture (raceway); cage culture, and; recirculating systems.
  2. Generate a data base from these four types of production systems, to help promote a reasonable choice of effluent discharge regulations by government agencies.

Aquaculture Wastes and Effluents

Description


The second Wastes/Effluents Funded Project.   Chaired by Fred Binkowski.


1.  Study and evaluate solid waste management by:


     a. Describing the relevant physical characteristics of fecal material from fish fed commonly used commercial feeds,


     b. Developing diets to maximize integrity of fecal pellets without loss of fish performance and compare the physical characteristics of these pellets to those in subobjective a, and  Read more about Aquaculture Wastes and Effluents

Aquacultural Wastes and Effluents: Their Characteristics, Removal, and Beneficial Uses

Description


The third Wastes/Effluents Funded Project.  Chaired by Bob Summerfelt


Objectives:


1. Document the fate of aquaculture waste components (phosphorus, nitrogen, solids) relative to feed input into traditional and newly designed aquaculture systems.


2. Evaluate the technical and economic feasibility of rapid solids removal/recovery appropriate for new aquaculture facility designs.

Yellow Perch Recirculating Aquaculture Demonstration and Research Project

(funded project 7)


Description


The seventh Yellow Perch Funded Project.  Chaired by Don Garling.


Objectives:


  1.  Evaluate recirculating aquaculture technology to optimize yellow perch growth, performance (survival, health, feed conversion), and water quality considering such factors as feed management, water replacement, flow rates, and density.

Advancement of Yellow Perch Aquaculture #4

Description


The fourth Yellow Perch Funded Project.  Chaired by Jeff Malison


Objectives:


  1.  To determine the commercial scale feasibility and improve on the best intensive tank and pond culture practices for the production of yellow perch fingerlings. 


  2.  To determine the commercial scale feasibility of raising food-size yellow perch in flow-through raceways or tanks, open ponds, and large net-pens, comparing the best available formulated diets. Read more about Advancement of Yellow Perch Aquaculture #4
