In addition to otter trawlers, gillnetters and line 

 trawlers, an unknown number of small "under tonnage" vessels 

 (vessels which carry no Guard documentation) account for 

 between 15 and 20 percent of pollock landings. These vessels 

 predominantly use line travels (62.4 percent) and gillnets 

 (22.3 percent). 



Processors of domestic origin pollock are located 

 primarily in Maine and Massachusetts. Most process a variety 

 of other fresh fish species in addition to pollock. Many are 

 relatively small, labor-intensive, family-type establishments, 

 NMFS unpublished data for 1976 indicate that 53 New England 

 plants processed some quantity of pollock. The majority of 

 these (37) produced fresh raw fillets. The next largest 

 number (9) produced frozen raw fillets. 



The impact on harvesters and processors of a potential 

 reduction in the supply of 4VWX+5 pollock depends on (1) the 

 extent of the reduction, and (2) their ability to substitute 

 other species or other sources for pollock supplies from 

 4VWX+5 at current levels. The impact on otter trawlers 

 would be less significant than the impact on gillnetters or 

 line trawlers since otter trawlers, except perhaps in 

 Gloucester and Boston, harvest pollock largely as a bycatch 

 in other groundfish fisheries. Otter trawlers in this sense 

 would be affected primarily by any bycatch limits introduced. 

 Gillnetters and line trawlers, on the other hand, might have
