Shore-Zone Seining 



Seining for shoro-zone fishes was conducted monthly from April 

 tJ'irough November at four New Haven Harbor locations: Long Wharf, Morris 

 Cove, Harbor Station, and Sandy Point (Figure 11-1). There were no 

 April collections for either 1971 or 1973, and only the Long Wharf site 

 was sampled in April 1972 (Figure 11-1) . A 100 ft x 6 ft, 1/4-in square 



mesh, beach seine was used throughout the program, sampling approxi- 



2 

 mately 10,000 ft per haul. 



Monitoring of Impingement 



United Illuminating Company personnel have regularly sampled 

 the fishes and other marine life impinged on the plant's travelling 

 screens since the start-up of the New Haven Harbor Station cooling 

 system pumps in July 1975. One 24-hr catch of impinged fishes was 

 identified, enumerated and measured each week by trained UI personnel.

Processing of Specimens 



Finfish captured in the otter trawl, gill net and seine sam- 

 pling programs were identified, enumerated, and measured (to the nearest 

 mm total length) in the field whenever possible. For otter trawl speci- 

 mens, only those captured in the first tow of a pair were measured; 

 specimens in the second tow were identified and enumerated only. When 

 samples contained numerous individuals of the same species, a random 

 sample of 25-50 individuals was measured; the rest were enumerated. 

 Total weight of each species in each sample was also determined in the
