In what capacity can the effects of by-catch from lawful and illicit, unreported, and unregulated fisheries be lessened to a level that will take into consideration inversion of declining patterns of influenced species?
The answer depends upon the type of fishery involved. For example, if we are dealing with lobsters, clams, and crabs, it is desirable to establish property rights for fishermen. They will then be careful not to exploit the fishery to exhaustion; they will also enforce their rights to expel trespassing fishermen. In contrast, with fish species that move around, it may be desirable to establish certain areas of the water where fishing boats are not permitted during some periods of time. The overarching issue here is to make enforcement of regulations inexpensive.
