Figure 6. --Comparison of length-frequency distributions of herring samples collected in the 

 Passamaquoddy Region during September in 1915, 1932, 1957, and 1958. 



Migrations . --Movements of herring in 

 and near the Quoddy Region were studied 

 to discover the source and the fate of the 

 herring in Passamaquoddy and Cobscook 

 Bays. In 1957 and 1958, 59 taggings in- 

 volved more than 137,000 herring. Re- 

 captures from 1957 taggings totalled 

 792 (2.1 percent) while recaptures from 

 1958 taggings totalled 2,790 (2.8 per- 

 cent). 



Recaptures showed that herring move 

 in and out of Passamaquoddy Bay from 

 points as far east as Point Lepreau and 

 as far south as southern Grand Manan. 

 No recaptures from Passamaquoddy Bay 



taggings were made to the southwest 

 along the coast of Maine. However, some 

 fish tagged on the coast of Maine moved 

 to Passamaquoddy Bay and beyond to 

 Point Lepreau. The pattern of recoveries 

 did not indicate clearly whether move- 

 ments were via Letite or Western Pas- 

 sage, but there was some indication that 

 both passages were used. Comparison of 

 drift-bottle and tag recoveries indicated 

 that herring do not always move in the 

 same direction as the surface currents. 

 While there is insufficient information to 

 establish a pattern of herring migrations, 

 there is a suggestion of random move- 

 ment.
