SAND DAB. 



This is also known as the Rusty Dab. It inhabits the coast of North America 

 from Labrador to New York. He Kay calls it the Rusty Flatfish, which he says is a 

 rarc '1 by the fishermen to occur only in deep water. The specimen 



described by him was iS inches long. According to Dr. Smith, it is very common in 

 Vineyard Sound and observed by him in water from 10 to 12 fathoms deep, where 

 it may be found throughout the year. Tin-re is no fishery, but numbers are caught 

 incidentally while bottom fishing for other species. In Great Harbor a few are taken 

 in fyke nets, only in winter. The average length there is about 14 inches. In 

 Massachus, it is a common resident species, inhabiting deep waters in 



summer, and approaching the shores in winter.
