I have a suggestion: let's outlaw exotic fishkeeping. Keeping exotic fish is perhaps one of the greatest pressures on native fish populations. I propose that from now on you can only keep exotic fishes if you are allied with an acredited institution (a school, a government, a political action committee, or nonprofit aquarium society), and have no monetary interest in their keeping. If you can not present these credentials or are not willing to pay for an annual permit, you will only be able to keep fishes found in the watershed* that you are currently occupying.
This rule would apply also to for-food fishfarms, as well.
*This is defined as fishes found to the non-marine watershed prior the existence of the organization known as the Peace Corps. For estuarine and marine fishes this is defined as species that occur naturally within a 100 km-radius of the ocean that you are closest to.
