Culture of Bluegill and Crappie for Food Fish #1

(Sunfish Funded Project 1)

Description

The first Sunfish Funded Project.  Chaired by Bruce Tetzlaff

Objectives:

1. To determine the mechanisms of sex control in sunfish and to produce and evaluate polyploid sunfish and hybrids.

2. To compare the optimum temperature-food conversion relationship of selected hybrids with those of the parentals, and to determine optimum stocking densities of hybrid sunfish.

Culture Technology of Centrarchids (Sunfish)

Description


The third Sunfish Funded Project.   Chaired by Don Garling


Objectives:


1. Produce a production manual, accompanying videos and other information as necessary to demonstrate the technology for culturing centrarchids.


2. Determine the major nutritional requirements for centrarchids and to compare their growth and performance using available commercial feeds in laboratory and field settings.

(funded project 4)


Description


The fourth Sunfish Funded Project.   Chaired by Bob Sheehan


Objectives:


1. Compare feeding trials for grow out of locally available 5.1-10.2 cm (2-4") black crappie and bluegill male x green sunfish female hybrids:

          a.  in ponds at dissimilar latitudes in the region, and

          b.  in recirculating systems using compensatory feeding strategies

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.

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.

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.

3. Demonstrate economically sound processing methods for beneficial use of aquaculture waste. Read more about Aquacultural Wastes and Effluents: Their Characteristics, Removal, and Beneficial Uses
