traps, and an additional 2-3 years to reach marketable size, there is a 

 lag of at least 6 years between the time of a potential impact on larvae 

 and the time at which we can detect that impact. Therefore, plant 

 induced effects (if any) on larval and juvenile stages that have occurred 

 since 1975 would only now be apparent in the 1981-82 catch. Thus, the 

 information collected since 1975 is providing long-term population data 

 needed to quantitatively assess any changes in the lobster population 

 due to Unit 3. 



To evaluate the effects of Millstone Units 1, 2 and potential 

 impact of Unit 3, the changes in the population will be detected by the 

 alteration of the basic population parameters now being collected. The 

 population size, and growth and movement of individuals can be compared 

 by station over time as a result of our tagging program. Sex ratios, 

 size frequencies, CPUE, the number of culls and berried females can be 

 evaluated over years and between stations. The stability of these 

 parameters during Unit 1 and 2 operation and after the start up of Unit 

 3 will demonstrate the effects (if any) of operating plants on Millstone 

 Point. 



We believe the present program should be continued through the 

 operational phase of Unit 3. In addition, we stress the commercial and 

 recreational importance of lobsters in our area and the favorable channel 

 of communication between our staff and these local lobstermen as a 

 result of our tagging program.
