COMMERCIAL FISHERIES REVIEW

portant contributors make significant contributions in only 6 months or even fewer. Some 

 species contribute heavily to the trash fish in only 1 month of the year. When trash fish are 

 being supplied from the winter trawl fishery (October through March), there appears to be a 

 greater amount of trash fish contributed by "all other fish" and a lesser amount by "inverte- 

 brates." 



In 1962, the differences in species composition and average individual size between catch- 

 es from the trawl and the long-haul and pound-net fishery are shown in tables 1 and 2. The 

 trawls catch primarily edible fish of small size but the long-haul seines and pound-nets catch 

 mostly nonedible species of larger size. Interestingly enough the heaviest contributor to the 

 trawl catch, croaker, is one of the least important in the other; conversely, menhaden which 

 hardly appears in the trawl fishery is the main species in the long-haul and pound-net fishery 

 and at the same contribution level (43 percent) as croaker was in the trawl fishery. In this 

 study the differences between these two gear fisheries have little significance because 95 per- 

 cent or more of the trashfishis supplied by trawlers. However, these differences should be 

 noted to serve as guides for future studies involving different types of fishing gear

Created in 1849, the Department of the Interior-a department of conservation—is concerned with the 

 management, conservation, and development of the Nation's water, fish, wildlife, mineral, forest, and park 

 and recreational resources. It also has major responsibilities for Indian and Territorial affairs. 



As the Nation's principal conservation agency, the Department works to assure that nonrenewable 

 resources are developed and used wisely, that park and recreational resources are conserved for the future, 

 and that renewable resources make their fuU contribution to the progress, prosperity, and security of the 

 United States-now and in the future.
