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:

  • Food for people
  • Bait for recreational anglers
  • Fish for stocking and
  • Plants and animals for ornamental use

It can also reduce dependence on wild harvested populations.

Aquaculture in the Great Lakes Region has been slow to meet expectations because of issues associated with cold-climate production technologies, species selection, marketing, international product competition, relatively restrictive regulations and inadequate business planning.

In some situations aquaculture can have negative environmental impacts such as excessive nutrients in effluent release, escape of cultured organisms, inadvertent spread of disease, introduction of invasive species and the addition of adverse genetic material to wild populations. One of Minnesota Sea Grant's challenges is to assist development 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.
