YEARS 



Figure 12. --Relative abundance of plankton inside and outside Passamaquoddy and Cobscook Bays. Only forms which

in deeper waters. In recent years the 

 average annual landings inside the pro- 

 posed dam areas have approximated 

 750,000 pounds of clEim meats and 60,000 

 pounds of scallop meats. The abundance 

 of both species has fluctuated widely 

 and will continue to fluctuate with or 

 without impoundment. Maintenance of 

 scallop populations seems to depend on 

 retention of the free- swimming larvae 

 over their native beds until they mature 

 and attach themselves. Evidence of ship- 

 worms, although not previously recorded 

 from Passamaquoddy Bay, was found 

 during this investigation in two tributary 

 inlets--Kitty Cove and Sam Orr Pond. 

 The species appeared to be Teredo navalis. 

 Another wood borer (Xylophaga) is com- 

 mon in the offshore waters of New Eng- 

 land and in recent years has invaded the 

 inshore waters south and west of Motint 

 Desert Island, Maine. 



Lobsters . --From 1952 to 1958, lobster 

 landings in the Quoddy Region averaged 



approximately 388,000 pounds. Of this 

 amount, about 102,000 pounds were taken 

 inside the proposed dam areas. Tagging 

 has shown that adtilt lobsters do not 

 move appreciably from one area to 

 another, and hence the stocks are con- 

 sidered to be relatively separate and 

 distinct. 



Anadromous fishes . --Anadromous spe- 

 cies with actual or potential economic 

 value in the Quoddy Region include At- 

 lantic salmon, trout, smelt, and alewives. 

 The entire value of trout and most of the 

 value of salmon lie in their fresh-water 

 sport fisheries. The Dennys River is the 

 most important salmon river and from 30 

 to 100 fish are angled there annually. 

 The Oigdeguash and Magaguadavic Rivers 

 now have quite good populations of young 

 salmon which probably contribute adult 

 salmon to commercicil catches over a 

 wide area of the Atlantic coast. The St. 

 Croix River has few naturally produced 

 salmon due to obstructions and pollution.
