mm.; the length rano-e, 42 to 110 mm. 

 This species also lives in the salt marsh in 

 the summer, although it is less common 

 than the mummichog. 



Gadidae — codfishes and hakes 



Merluccius b/V/Hfc/r/.s (Mitchill) , silver hake. 

 One silver hake. 80 mm. long, was caught 

 in late November 1962. 



Microf/adiis tomcod (Walbaum), Atlantic 



tomcod. 



Tomcod were most common from spring 

 to late summer (table .3, fig. 3). Young 

 of the year fish 27 to 47 mm. long were 

 first caught in Ajiril; by August, fish of 

 what we assumed to be this same age 

 group were 80 to 122 mm. long. 



Pollachius virens (Linnaeus), pollock. 

 All pollock caught were 0-group fisli, ac- 

 cording to growth data given by Bigelow 

 and Schroeder (1953) (table 4, fig. 3). 

 Their avei'age length was 30 mm. in late 

 March (when they first api^eared in the 

 catch) and 52 mm. in early June (when 

 they became scarce) . These fish may have 

 left the area because of rising water tem- 

 peratui'e. 



Urophycis chnss (Walbaum), red hake. 

 Ten red hake were caught in Seijtemljer 

 to November 1962. The eight of these 

 that were caught in October and November 

 (mean length, 104 mm.; range, 68 to l-">6 

 mm.) probably were young of the year, 

 since this species spawns in spring and 

 summer; however, age was not deter- 

 mined. Seven of these eight were caught 

 in the night tows of October 22-23. The 

 two fish caught in September (262 and 

 26;; mm. long) apparently were of an older 

 age group. 



Urophycis tennis (Mitchill), white hake. 

 Sixteen white hake, 41 to 171 mm. long, 

 were caught in May to July 1962 (table 5) . 

 We judged that these were O-grou]) fish 

 which were spawned during the previous 

 winter, for Marak, Colton, Foster, and 

 Miller (1962) found small white hake 27 

 to 68 mm. long still planktonic in the Gulf 

 of Maine in May and June.

stickleback. 



The fours]iine stickleback was one of the 

 few s])ecies caught in all months of the 

 year (table 6, fig. ."). Most were caught
