US Aquaculture of Finfish, Shellfish and Seaweeds

Aquaculture production is growing: demands for healthy seafood products are increasing as stocks of wild-caught seafood are dwindling from overfishing and other factors. Developing technologies that reduce production costs and maintain or improve product quality will help U.S. aquaculture producers meet that increasing demand. Aquaculture research supports efforts to ensure that a healthy, competitive, and sustainable aquaculture sector is able to produce an abundant, safe, and affordable supply of seafood products, advancing the efforts of more than 4,300 domestic aquaculture farmers producing more than $1 billion dollars' worth of goods annually to meet demands of U.S. consumers.

Selective Breeding in the Eastern Oyster, Crassostrea virginica

Domestication of the eastern oyster has been ongoing for more than two decades-from mass selection to family-based breeding and soon, hopefully, genomic selection. This talk will cover the current state of oyster breeding research in the U.S., focused primarily in the mid-Atlantic, and will include a brief discussion of polyploid breeding strategies.

Identifying the Biological Basis of Specific Phenotypes in Rainbow Trout

In comparison to most terrestrial agriculture livestock, the domestication and large-scale production of finfish is a much more recent endeavor. Several of the important genetic traits for which terrestrial livestock have undergone selection are currently being selected in finfish. However, physiology and environmental conditions present some unique challenges for aquaculture. Overturf's presentation will focus on the identification and selection for specific traits and the attempts to understand the physiological basis for these traits in fish.
