Activity 19: Making Sustainable Fishery Decisions

Get Started

Briefly review your summary of the fishery-management strategy you were assigned in the previous activity.

Read the introduction


Which fishery management strategy is the best choice for the sustainability of the Avril Gulf tuna fishery?

Challenge


Procedure

Examine each set of Fishery Indicator Cards with your group.

Procedure

Summarize the trend indicated by the information on each card.

Use the terms population, growth rate, and indicator in your summaries.


Procedure

In Step 2, be sure you include explanations for your predictions. Refer to Student Sheet 18.1, “The Avril Gulf Tuna Fishery” and our class chart, “Current Condition of Avril Gulf” from the previous activity


Procedure

In Steps 3 - 5 you decide which indicators to monitor and for how long, keep in mind the trade-offs involved in formulating your plan.

In Step 7 be sure to compare the data on each card to its corresponding Fishery Indicator Card.


Procedure

What are the benefits of pooling the data you collected with the data other groups collected?

What are the overall benefits and trade-offs of the two fishery management strategies?


Follow Up

Which fishery strategy appears to be the most sustainable for the Avril Gulf tuna fishery? Explain why.
