In fact it's just the opposite. I believe that the regulatory agenda has to balance the multiple needs and that is why they are so difficult. To illustrate, consider the shrimp business in the Gulf of Mexico. The shrimp move from the bayous and the estuaries in the springtime. They go out into deeper waters as the summer progresses and they get bigger.
Larger shrimp are worth more than small shrimp.
The obvious idea would be to let the inshore shrimp get bigger and take them out in the deeper water. They need to be able to take some of those shrimp when they are small and inshore. What if you throw into the mix the fact that these small boat operators have a higher interdiction rate with turtles because the turtles are also inshore. Add to this the factor of refugees from Vietnam as part of the shrimp fleet or displaced oil workers with nothing else to do. These are all considerations to put into the regulation of how you should catch shrimp in the Gulf of Mexico.
