Aquaculture

Aquaculture is the general term used to describe the breeding and rearing of aquatic animals and plants in controlled or selected environments. Aquaculture can provide fish for:

  • bait
  • ornamental use
  • stocking and
  • food for other fish or people

It can also reduce dependence on wild harvested populations.

Aquaculture in the Great Lakes Region has not met expectations because of problems associated with climate, production technologies, selecting appropriate species, marketing, competition from outside the region, and business planning.

Aquaculture can also have negative environmental impacts from effluent release, escape of culture organisms, use of natural waters, disease, invasive species spread, and from genetically modified organisms. One of Sea Grant’s challenges is to develop and promote environmentally acceptable and economically viable aquaculture techniques, especially for the Great Lakes Region.

Redtail Chub Aquaculture PotentialRedtail Chub Aquaculture Potential
The redtail chub is one of the most valuable baitfish species in Minnesota. Developing an economically viable aquaculture system for hornyhead chubs could relieve pressure on wild populations while keeping the market adequately supplied with this desirable bait. We explored the aquaculture potential of this species.
AIS-HACCP
Aquatic Invasive Species – Hazard Analysis and Critical Control Point (AIS-HACCP) is a method to help prevent the spread of Aquatic Invasive Species via aquaculture, fish stocking, wild baitfish harvest and resource management, research, and enforcement activities.
