Correlation studies. --Correlation stud- 



ies were undertaken because an tinder- 

 standing of the changes associated with 

 present fluctuations in the herring catch 

 might assist materially in predicting 

 changes restilting from the dams. It was 

 impossible, however, to establish any 

 consistent correlation between catch and 

 such factors as river discharge, wind 

 speed and direction, air and sea tempera- 

 tures, salinities at various depths, plank- 

 ton, and cloud cover. 



Other Species 



Groundfish .-- Commercially important 

 species of groundfish in the Quoddy Region 

 are pollock, haddock, cod, hake, and 

 winter flounder. Hake and cod are scarce 



inside the proposed dam areas. Large 

 catches of pollock are made in the low- 

 pool area and small catches of haddock 

 and winter flotinder in the high-pool area. 

 The present (1958) catch of all groundfish 

 species in the Region is approximately 

 6 million pounds, of which approximately 

 2 million pounds (chiefly pollock) are 

 taken inside the proposed dam areas. 

 The haddock are fast-growing fish of the 

 type caught off the New England States. 

 Tagging studies show that they migrate 

 south for the winter months and spawn 

 outside the Region. 



Mollusks .--OnIy two species of mol- 

 luscan shellfish are harvested from the 

 Quoddy Region in sufficient quantity to 

 warrant consideration: soft- shell clams 

 in the intertidal zone and sea scallops
