4-H aquaculture challenge

What is aquaculture? Why is it becoming a growing industry?
Globally, fish consumption has nearly doubled in the last 40 years. At the same time wild fish capture has leveled off. This is due to decreasing wild stocks and high scrutiny of fishing practices. As a result, aquaculture has become one of the primary solutions to the worldwide demand for seafood. Students will “engineer” a fish feeder to make an aquaculture operation more efficient.

# 4-H Aquaculture Challenge

Students follow an engineering design process to create an efficient fish feeder. (The mat should be copied on a large-format printer to be 40” × 40”.)


Teacher background

Aquaculture uses high amounts of fish meal and fish oil to feed the fish. Soybean protein has been found to be an more cost-effective solution for feeding fish while still achieving a similar rate of growth. Various fish are being used to meet the increasing demand for fish including: yellow perch, freshwater shrimp, tilapia and more.

For additional information about aquaculture and careers in this growing field, take the Aquaculture and Soy Protein e-learning course and watch the Global Aquaculture career video.
