Description

The U.S. catfish industry encountered a similar need to be efficient and competitive and developed intensive aeration and split pond designs to increase production levels and ultimately bottom lines. Similar strategies may be applicable to NCR pond production but need to undergo “Proof-of-concept” on-farm trials prior to dissemination to the yellow perch industry and other NCR industries.

Description

The general focus of this project will be to collaborate with the North Central Regional Aquaculture Center’s (NCRAC’s) Industry Advisory Council (IAC) to develop a sustainable program that will be beneficial for established farmers throughout the Midwest; which will hopefully increase productivity and decrease costs.

Description

We propose to optimize and combine two technologies (e.g., sex reversal and triploidy) to produce walleye Sander vitreus with superior production traits. We will produce gynogenetic masculinized walleye and cross these individuals with walleye females. Resulting zygotes will then be subjected to pressure shock, producing triploid (sterile) all-female offspring.

Description

We hypothesize that optimization of dietary carbohydrate used in fish feed will help to increase fish health and growth performance as well as reduce feed cost for yellow perch. Specifically, we will investigate how different carbohydrates influence 1) growth performance and nutrient utilization in laboratory and farm conditions; 2) fish tolerance in response to acute temperature shocks or hypoxia challenge; and 3) bacterial community composition and active community fraction in the host gut across diet regimes.

Description

This project proposes a survey within the North Central Region (NCR) to identify marketing channels’ choices of seafood according to their constraints and demand perception. Assuming that marketing channels define the pool of options from which consumers choose seafood species and product form, this survey will be designed to identify their preferences and willingness to pay for farm-raised seafood, by species, quantity required, quality perception and preferred form of product.

Description

Given the NCRAC goal of “establishing strong and vibrant state aquaculture associations,” it is essential to first have a thorough understanding of 1) why some aquaculture producers choose to join associations and others do not; 2) how producers value the various types of activities undertaken by state associations; 3) what types of services or programs would attract membership; and 4) what barriers and challenges exist to organizing and sustaining state aquaculture associations.

Description

We propose to conduct comprehensive environmental and energy audits of five representative facilities during winter and summer, develop solutions to observed problems, and to disseminate findings and recommendations via publications and presentations to producers, consultants, extension personnel, and other stakeholders.

Description

We will analyze sperm from these males using flowcytometry to verify exclusive production of “X” sperm. DNA from “X” sperm will be analyzed against an annotated yellow perch genome, to characterize sex-determining genes. Finally, these selected sperm samples will be cryopreserved and stored in a pilot cryo-bank.

Description

This project proposal will complement the webinar series, and enhance learning outcomes for participants by providing multiple hands-on, advanced aquaculture techniques workshops throughout the NCR. Topical areas for these fee-based workshops will include but not be limited to culture techniques for important NCR aquaculture species, advanced aquaculture systems design and management, aquaculture business and marketing, water quality maintenance, advanced fish health diagnostics and aquaculture regulatory issues.

Description

Effectiveness research leading to approvals for controlling mortality in coolwater and warmwater finfish due to aeromonad infections with Terramycin 200 for fish® (oxytetracycline dihydrate) and Aquaflor® (florfenicol).

Objectives:

1. Identify the etiologic agent (Aeromonas spp.) from isolates collected from disease outbreaks in the NCR and characterize the disease syndrome before conducting any effectiveness studies.

Description

The objectives of this study, from July 1, 1996 through December 31, 1997 were

1. To conduct a Target Animal Safety Study under Good Laboratory Practice (GLP) compliance for walleye fingerlings fed 17a-methyltestosterone.
2. To evaluate selected dosages of 17a-methltestosterone for effiacy at inducing sex inversion in walley.
