Dam were reviewed. During April and May 1974, NAI conducted a series of 

 investigations in the Mill and Ouinnipiac Rivers and the Grand Avenue 

 Reach of New Haven Harbor for United Illuminating (NAI, 1974c). Fishes 

 were sampled each month with two types of seines and with gill nets. 

 Both seines and gill nets were dissimilar to those used in the New Haven 

 Harbor Station Ecological Monitoring Studies (NHHSEMS) . Ichthyoplankton 

 were also sampled using a 1 meter, 505 ym mesh net. 



Studies for the City of New Haven 



Gill nets were fished in the West River area of New Haven 

 Harbor during July and August 1974 as part of a study conducted for the 

 City of New Haven by NAI (1975b). These nets, also unlike NHHSEMS nets 

 in dimensions and construction, were fished overnight at four locations. 



Pre- 19 71 New Haven Harbor Station Studies 



Prior to commencement of the NHHSEMS in 1971, monthly otter 

 trawling (16 ft, semiballoon) was conducted by Raytheon Company (1971) 

 at locations roughly equivalent to NHHSEMS Stations 3, 4, 5, 8, 11 and 

 13 from June through November 1970. Beach seining (50 ft x 6 ft, 1/4 

 in. square mesh) was also conducted monthly from Jione through November, 

 at Morris Cove, Fort Hale, the Harbor Station site, and on the north and 

 south sides of Sandy Point. 



Published Studies of the New Haven Harbor lahthyo fauna 



The only published investigation of New Haven Harbor fishes to 

 date is that of Warfel and Merriman (1944) . These authors reported the 

 results of a year-long seining program conducted at Morris Cove. Although 

 a Morris Cove seine station was also included in the NHHSEMS, direct 

 comparisons with these historical data are limited because of differ-
