Junior STEM: Design A Fish Farm




In Australia, there are commercial fishers who supply wild-caught fish for domestic consumption and export, and recreational fishers who catch fish for personal eating and recreation. 

There are also many aquaculture and fish farmers who farm fish for our consumption. There are a range of aquaculture production systems where some kinds of shellfish and fish are farmed in ponds, pens, tanks, cages, baskets and racks.

Your challenge is to research what fish farms look like and the technologies they use to raise, feed and grow shellfish or fish like salmon, trout and tuna.

Then design a floating fish farm and make a model with pipe cleaners, plastic mesh, hessian, balloons, polystyrene, weights, bubble wrap, paper straws, sticky tape, textas, glue and thick card. 


Decide which criteria will be used in your fish farm. Will your fish farm:

  • Make it easy to catch the fish?
  • Be seal proof?
  • Have plenty of water circulation?
  • Prevent fish waste entering the sea? and
  • Be able to cope with big waves and storms? 


Design, make and share your design as part of National Science Week.

Students are given an insight into ways primary producers in the fisheries, meat and livestock sectors produce; process and bring their products to consumer
