2. Test Besults . 



a. Borers . Teredinldae were very active throughout the 

 brief period covered "by the test, and it is clearly apparent that the 

 "breeding season is continuous throughout the year. The attack rated 

 very heavy in 19k6, Lljnnoria also vere active and extremely ahundant 

 throughout the period covered "by the test, occurring in exceptionally 

 large numbers in the control panels. The attack was extremely severe 

 in 19^6. No Pholadidae vere recorded at this location. 



"b. Fouling OrAaniams . Silt and invertebrate animals 

 "belonging to k phyla contributed to fouling of the panels. The phyla 

 conprised hydroids, encrusting and filamentous Bryozoa, serpulid 

 vormBf and Jingle-shells. Hydroids, encrusting and filamentous Bryozoa, 

 and serpulid worms occurred with great frequency, while the occurrence of 

 the Jingle-shells was merely very occasional. The test was unusual in 

 that the heretofore ubiquitous barnacles and tunicates were absent. 



The operation of this test 'board was not continued long enough 

 to provide conclusive inf oimation on the breeding habits and development 

 of the marine borers and fouling organisms at this location, but it does 

 show the general trend.
