1. Inata] latlon . Test iDoarcLs of the panel type were operated 

 at two locations on Wake Atoll from January 10, 19^6 to June 10, 19^7 » 

 to determine the Identity and preyalence of marine borers and fouling 

 agents. 



2. Test Results , 



a. Borers. Teredlnidae were extremely active ajid destructive 

 at toth locations, and breeding occurred continuously throughout the 

 year. The attack rated very heavy at "both locations and especially 

 so at the first location. Limnoria also were active at "both locations 

 throughout the year, the attack rating heavy. No Pholadidae were 

 recorded at either location. 



h. Foulinf^ Organisms . Silt, algae, and invertebrate 

 Einlmals "belonging to 5 phyla contrihuted to fouling of the peuiels. 

 The phyla comprised hydroids, encrusting and filamentous Bryozoa, serpulid 

 worms, oysters, and tunicates. Silt occmrred regularly on all the 

 panels ^at hoth locations . Algae occurred on most of the panels at 

 location No. 2 but only sporadiceilly at location Wo. 1. HydrOids and 

 encrusting Biyozoa occurred frequently at location No. 2 but only 

 sporadically at location No. 1. Serpulid worms occurred fairly fre- 

 quently at location No. 1 but only occasionally at location No. 2. 

 The occurrence of the other organisms was purely sporadic or occasional.
