Fisheries bioeconomics is traditionally 99% economics and 1% biology. We are trying inject a little more biology to the field.
'Biologizing' fisheries bioeconomics is a big task, and we are currently working with two specific problems.
- It is common that big fish are more valuable per unit weight that small ones, tuna being one of the most extreme examples. Yet most of fisheries bioeconomics ignores this fact. We are trying to understand how considering size-dependent pricing influences optimal harvesting policies.
- Fisheries-induced evolution changes characteristics of fish stocks, in terms of parameters such as yield, mean individual size and extinction risk. What are the economic consequences?
