πŸ“š  Prior learning: Overfishing; Sustainable fishing

Sustainable fishing sounds easy!  But working out whether fish are being fished sustainably is tricky. Scientists collect data and use mathematical formulas such as the ‘Maximum Sustainable Yield’ to help them work out what level of fishing can occur without causing a decline in fish stocks. 

Focus Questions:

What is 'maximum sustainable yield’?

What is the role of science in ensuring fisheries are sustainably fished?

What new words and concepts have we learnt?

Learning Outcomes:

Understand the concept of Maximum Sustainable Yield (MSY)

Investigate the role of science in ensuring fisheries are sustainably fished

Use scientific and fishery related vocabulary

Materials:

Scientists & MSY SLIDES

How fish stocks are assessed in Aotearoa

Activities investigate how scientific data is used to assess the sustainability of fisheries in Aoteaora New Zealand.

In Aotearoa New Zealand commercial fishers must report their catches and sometimes fishery observers go out with commercial fishers to collect extra information.  Scientists use all this information to get an idea of how many fish there are (abundance).

Focus Questions:

How do we assess fisheries in Aotearoa New Zealand?

What is the role of science in ensuring fisheries are sustainably fished?

What new words and concepts have we learnt?

Learning Outcomes:

Describe how we assess the sustainability of fisheries in Aotearoa New Zealand
