This is the plaice according to Mitchill; it is known also as 

 the watery flounder. De Kay calls it the spotted turbot and 

 sand flounder. In Great Egg Harbor bay it is the window light. 

 Windowpane and daylight are other names applied to the 

 species. De Kay saw specimens 18 inches long. He says it is a 

 delicate article of food. 



The windowpane is found on the east coast from Maine to 

 North Carolina. Though abundant and well flavored and some- 

 times reaching a length of a foot or more, it is not an important 

 food fish. In Gravesend bay the fish delights in cold water. It 

 is not adapted to captive life. In Great South bay we took it at 

 Fire Island beach at the end of September 1890. In 1898 an 

 individual was taken at Islip August 18. Young examples were 

 obtained at Fire Island inlet and Oak Island beach in September. 

 In 1901 young individuals were obtained July 31 and Aug. 15 in 

 Fire Island inlet. At Woods Hole Mass, according to Dr Smith, 

 it is found from April to late in the autumn. There is quite a 

 large run about June 1, when the fish is full of spawn. The 

 average size there is 10 to 12 inches. In experimental hatching 

 of the eggs at Woods Hole, it was found that the eggs were buoy- 

 ant, nonadhesive, -& of an inch in diameter, and that they hatch 

 in eight days when the average water temperature is 51 

 to 56 F.
