Weekly means at LR during 1983-85 were similar by year until about late June; means were 6 to 8 

 mm greater thereafter during 1983 (Fig. 26). Those during 1984 and 1985 were more alike with growth 

 slightly less during the latter year. The reasons for these differences among years are not known. Although 

 water temperatures appeared to be comparable, life history data such as food preference, rates of feeding, 

 and predation upon young are not available. Apparent annual changes in growth may also be caused by 

 differential movement of larger young away from the station, which would also increase the apparent 

 mortality rate. However, only a few average-sized young were taken during the summer at trawl station 

 NR and none at the Niantic Bay stations. Thus, neither large-scale movements nor differential movements 

 by size seemed to have occurred, at least into areas sampled by trawl.
