mesh. Both are made of cotton twine. Diving and spearing of fish are negligible. There 

 are quite a nuinber of small seines ■Rhich are used in nultiples of 30 feet by tying sections 

 together. 'Ihese seines axe straight, about three feet deep and of one inch stretched mesh 

 of cotton twine. Ihere are only a few scattered places where seines can be used because of 

 the rough bottom. Spiny lobsters are fairly abundant and a good many are taken at night by 

 torching, Octopi ai'e also very common up to three feet in total spread. Both the spiny 

 lobster and the octopus are regarded very highly as food by the Guamanians and they also 

 eat the small black tipped sand shark ( Eulamia melanopterus ) . 



Although there are a few small outrigger canoes 12 to liV feet in length, these are 

 very roughly constructed and have relatively little carrying capacity. The Guamanians pre- 

 fer United States manufactured small boats, both power and sail. 



The most promising locality for increasing production is at Umatac. There are a 

 number of good fisliermen here v/ho are experienced in going off-shore and who have in the 

 past operated gill nets for mackerel vdth good success. It is repoi'ted that their catch 

 amounted to ^0 to 50 thousand pounds of mackerel a week during the season. Here again 

 increased production would be dependent on establishing refrigeration and transportation 

 facilities. 



Because of its partial isolation there are more fish around Cocos Island than around 

 the shore of Guam itself. On the lee side of the island there v/ere schools of large mullet 

 Ui to 16 inches long, larf:e crevalle of 10 to 15 pounds and blue wrasse (Cheilinus sp.) 

 (Fig. 36) up to 30 pounds mere observed on the seaward side. Goat-lish up to ten inches 

 in lenf^h also mere common. For further recoi-.imendations concerning iisheries on Guam, 

 see Part III Summary and ice commendations (IV L).
