NORTH AND MIDDLE ATLANTIC FISHERY INVESTIGATIONS 
O. E. SETtTr, in charge 
The upward surge in fish prices and the increased activity in 
the fishing business which were noted in 1935 continued in 1936, 
with the Tesult that New England fishery landings reached the 
highest figure in recent years. Although there was a decline in the 
landings of several of the staple species such as mackerel, haddock, 
and cod, this decline was more than offset by increases in the land- 
ings of rosefish from 17 to 66.6 million pounds, and in vessel-caught 
whiting from less than 2 to nearly 18 million pounds. The fishing 
fleet operated at nearly full capacity throughout the year and ex- 
perienced its first major expansion since predepression years with 
the addition of more than a dozen new boats to its numbers. Six 
of these were large otter trawlers averaging 120 feet in length and 
500 horsepower. 
The productivity of the various species In general remained satis- 
factory, although the mackerel catch declined 24 percent from the 
previous year, owing to a lowered abundance of mackerel as a result 
of poor survival from the spawning of 1935. However, the catch 
remained considerably above the average for the present decade. 
The haddock fishery on Georges Bank continued to improve from 
the low level of 1930-31, but remained far below the 1925-29 level. 
On the Nova Scotian Banks the average productivity was less than 
during the preceding year owing to the scarcity of haddock spawned 
since 1929. 
Biological investigations were confined to a few of the more im- 
portant ‘New England and Middle Atlantic fisheries problems. Many 
others could not be covered because of limited personnel and facili- 
ties. Among these was rosefish, which has reached the proportions 
of a major fishery and about which little is known. The cod popu- 
lation has been subject to increasing exploitation as the haddock 
supply has diminished, but it is not known what effect the increased 
strain foe had uber its abundance. The yield of flounders has de-
