Advancing Hybrid Striped Bass Culture in the North Central Region

Description


The third Hybrid Striped Bass Funded Project.  Chaired by Chris Kohler


Objectives:


1. Obtain and maintain (in captivity) populations of spawning size white bass and striped bass.


2. Evaluate the effects of selected photoperiod/temperature and hormonal manipulations on gonadal development and spawning in white bass brood stock.

Culture Technology of Hybrid Striped Bass (HSB Project #4)

Description


The fourth Hybrid Striped Bass Funded Project.  Chaired by Chris Kohler


Objectives:


1. To develop intensive hatchery production techniques for white bass and to "domesticate" white bass by producing brood stock originating from induced spawns.


2. To perfect cryopreservation techniques for white bass/striped bass semen and to demonstrate feasibility of hybrid bass production using "stored" semen in industry-type setting.

Rapid Determination and Amino Acid Requirements of Lepomis Sunfish

Description

The second nutrition funded project.  Chaired by Robert Hayward.

Objectives:

1.  Develop a least-cost diet for bluegill Lepomis macrochirus by:

(a) Evaluating amino acid availability of dietary ingredients for bluegills,

(b) Evaluating amino acid composition of bluegills,

(c) Evaluating limiting amino acid requirements of bluegills, and

(d) Making a least-cost diet formulation model available to the industry within a two-year period. Read more about Rapid Determination and Amino Acid Requirements of Lepomis Sunfish

Feed Training Carnivorous Fish

Description


A project on feed training carnivorous fish was initiated in September 2006.  This project is chaired by Anita Kelly, Southern Illinois University-Carbondale.


The objectives of this project are:


1. Evaluate strategies including harvest, transport, environmental, and husbandry, to increase survival, growth, to maximize the percent of advanced yellow perch fingerlings trained to accept formulated feeds

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.

Culture Technology of Sunfish #1

(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.

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.

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.
