that the Coimcils will continue these plans, with modifications, and will, 

 in all probability, add other species to the list. 



E.2. Fisheries 



In most cases it is not possible to define fisheries, in economically 

 relevant terms, based on species. This is because multiple species fisheries 

 are involved. Provided gear or vessel modifications are not prohibitively 

 expensive, the same vessel can be employed in fishing for several species. 

 Indeed, in many cases the same vessel catches several species simultaneously. 

 Marginal adjustments in the species composition are possible by altering 

 fishing strategies or timing. Fundamentally, however, one must for economic 

 purposes classify many fisheries by type of vessel and gear. Appendix Table 

 A. 3 provides such a classification for the New England and Pacific fisheries. 

 As indicated in this table, the number of fisheries under this classification 

 is much less than under a species classification scheme. It may be noted 

 that these fisheries generally consist of aggregations of the species listed 

 in Appendix Tables A. 1 and A. 2.
