FISHES OF NEW YOUK '!"! 



This barracuda is not seen in our markets, but the adults of 

 more southerly species are considered excellent food fishes. At 

 Key West and on Cozumel island, and in the West Indies, the 

 barracuda is highly prized. 



Several young barracuda were caught in G-ravesend bay in 

 September 1896. The species is not common in that bay. An 

 individual 5^ inches long was seined at Sandy Hook, Oct. 8, 1897. 

 The fish does not live long in captivity.
