Scientists and policy makers often have to work together to set catch limits on fisheries. Imagine
that a policy maker proposes to allow the fishing of
a certain species to go on at current rates
because, she says, “Fishing at current rates will
not impact the ecosystem. We are removing fish
at a rate lower than the birth rate of their
population." Is this claim valid? What indicators
would you look at to support or disprove this
claim? Explain your reasoning.
