Developing Genetically Fast-Growing Monosex Male Populations in Bluegill

Description

The sixth Sunfish Funded Project.  Chaired by Han-Ping Wang

Objectives:

1.  Identify additional super-males and performance-selected females from existing populations.

2.  Create all-male bluegill populations by crossing super-males with females of selected and non-selected stocks.

3.  Rear Populations at two or more locations in the NCR.

4. Compare sex ratios and production characteristics of sub-populations as based on maternal stocks.

Tilapia Aquaculture in the North Central Region #1

(funded project 1)


Description


The first Tilapia funded project was chaired by by Don Garling.


Objectives:


1. Develop and/or identify cost-effective feeds for tilapia culture in recirculating systems that minimize waste generation.


2. Compare and evaluate economically important traits for current commercial tilapia strains in the North Central Region with other strains cultured in recirculating systems.

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.

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
