444 SEVENTH REPORT OF THE FOREST, FISH AND GAME COMMISSION. 



names, the New York Pollack, the Coalfish. and the Green Pollack. DcKay says 

 the fish is taken with the common Cod, but is by no means common on the coast 

 of New York. He saw a specimen weighing 17 pounds, and measuring 38 inches in 

 length. In another description he states that the Coalfish is often taken off the 

 harbor of New York in company with the Cod, and is known as Pollack and Black 

 Pollack. The third form under which the fish was known to DeKay was described 

 by him from a specimen captured by hook out of a large school in Long Island 

 Sound. The Pollack enters Gravesend Bay in the fall. In captivity it is a ravenous 

 feeder. It requires cold water and will not endure high temperatures. 



DeKay states that the fish flipped in the same manner as the Menhaden, and was 

 at first supposed to be of that species. The school seemed to be very timid, for, on 

 a very slight noise in the boat, they all disappeared. 



Dr. Smith states that adult Pollack appear in Vineyard Sound, Great Harbor, 

 Woods Hole, Mass., in May, following the run of Cod. They depart when the tem- 

 perature of the water reaches 60° or 65°. In April there is a run of Pollack measur- 

 ing from I to I JX inches long. By June, when these fish leave, they have reached a 

 length of 4 inches. In fall there is a small run of Pollack 7 or 8 inches long. The 

 average weight of adults in that locality is about 10 pounds, the largest one seined 

 having weighed 14 pounds. In Massachusetts Bay this is an extremely abundant 

 species, and constitutes an important food resource.

This fish is very generally known in New York waters under the name of Frost- 

 fish. It ranges from Nova Scotia to Virginia, and is excessively common in shallow 

 bays in cold weather. The name Frostfish is derived from the fact that it appears
