Larval studies 



The history and development of the current 

 ichthyoplankton sampling programs were given 

 in NUSCO (1987). Samples for winter flounder 

 larvae in 1986 and 1987 were taken in Niantic 

 River at stations A, B, and C and in Niantic Bay 

 at EN (entraiimient sampling) and NB (Fig. 2).

Collections in the river and at NB were made 

 with a 60-cm bongo sampler with 3.3-m long nets 

 towed at approximately 2 knots and weighted 

 with a 28.2-kg oceanographic depressor. Volume 

 of water filtered was determined using a single 

 General Oceanics (GO) flowmeter (model 2030) 

 mounted in the center of each bongo opening. A 

 stepwise oblique tow pattern was used with equal 

 sampling time at surface, mid-depth, and near 

 bottom. The length of tow line necessary to 



sample the mid-water and bottom strata was 

 based on water depth and the tow line angle as 

 measured with an inclinometer. Winter flounder 

 larvae entrained by MNPS were collected at Units 

 1 and 2 discharge (station EN) using a gantry 

 system to deploy a 1.0 x 3.6-m plankton net. 

 Four GO flowmeters were positioned in the 

 mouth of the net to account for horizontal and 

 vertical flow variation; sample volume was deter-
