Avril Gulf Tuna
Population Simulation

Science and Global Issues: Biology — Ecology: Living on Earth, Activity 14
 = 2000 tuna

 
 

Stage One

In this stage you will examine how birth rate, death rate, and migration rate affect the sustainability of the Avril Gulf tuna population. The instructions on your Student Sheet will help to guide you.

Stage Two

In this stage you will examine how
predators, amount of food, and incidents
of disease and pollution affect the
sustainability of the Avril Gulf tuna
population. Continue to refer to your
Student Sheet for specific instructions.

Stage Three

In this stage you will examine how
fishing intensity and length of fishing
season affect the sustainability of the
Avril Gulf tuna population. Continue to
refer to your Student Sheet for specific
instructions.

Stage Four

In this stage all of the variables can be
manipulated to determine their collective
affect on the sustainibility of the Avril Gulf
tuna population. Continue to refer to
your Student Sheet for specific
insructions.
