Fisheries economics

Managing fisheries is about managing the people. And people react to economic incentives. Therefore, fisheries management needs inputs from fisheries economics.


Past and present, we have addressed a number of problems:

  • When can effort regulation achieve conservation of rare species in mixed fisheries by encouraging fishers to target the abundant ones?
  • Related to above, what is the ability of fishers to target specific species?
  • 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?
