FISHERY BULLETIN: VOL. 82, NO. 1 



the fishes caught at inshore sites (Table 2). At beach 

 station 8, alewives, Alosa pseudoharengus; Atlantic 

 herring, Clupea harengus harengus; and American 

 smelt, Osmerus mordax; appeared in mid-July and 

 increased in abundance during August (Fig. 5). Her- 

 ring were abundant in estuaries during summer and 

 were replaced there by smelt in winter (Table 3). 

 Large American smelt were present at offshore sites 

 in Passamaquoddy Bay in mid-summer as observed 

 by Tyler (1971). During most winters, juvenile Atlan- 

 tic herring (10-20 cm) were abundant at offshore 

 sites, particularly inside Passamaquoddy Bay at 

 intermediate depths (station C; Fig. 10). Catches 

 were variable, possibly because of schooling 

 behavior (Brawn 1960). Tagging experiments indi- 

 cate herring move from inshore during summer to 

 deeper water in winter (McKenzie and Tibbo 

 1961). 

 Six species of sculpin (Table 2) were commonly 

 encountered at offshore station of which two — 

 longhorn sculpin, Myoxocephalus octodecemspino- 

 sus, and sea raven, Hemitripterus americanus — were 

 abundant, regular components (Fig. 1 1). Juveniles of 



most species were common at beach sites in summer 

 (Table 4) and at station A in winter (Table 2). 

 Increases in abundance of longhorn sculpins at sta- 

 tion B during winter were observed (Fig. 1 1) and may 

 be the result of migration out of Passamaquoddy 

 Bay. Two small species, Arctic hookear sculpin, 

 Artediellus uncinatus, and mailed sculpin, Triglops 

 murrayi, were winter occasionals at station A. They 

 were perhaps more abundant than catch rates 

 indicated (2-5/tow) because their maximum size 

 range was at the lower limit of catchability for our 

 trawl. 



The blennioid-like fishes were represented by 

 seven species (Tables 2, 3) of which ocean pout, 

 Macrozoarces americanus, was regular at offshore 

 stations in Passamaquoddy Bay (Fig. 11), and rock 

 gunnel, Pholis gunnellus, was a regular component at 

 beach sites (Table 4). Ocean pout abundance in 

 Passamaquoddy Bay was generally highest in early 

 summer and declined thereafter (Tyler 1971; Fig. 

 11). Abundance of ocean pout usually increased at 

 station B in late summer and fall, suggesting move- 

 ment from Passamaquoddy Bay to the Bay of Fundy.
