 oxygen concentrations of less than 0.6 ml. 

 per 1. These conditions could arise when 

 tidal and wind velocities are low and 

 temperatures are high.

Determination of the indices of refradtion

 that the cones are homogeneous. The entire

 tightly closed bivalves by Busycon and other 

 predators. Ecology, vol. 32, No. 1, p. 73-83. 

 Experimental cage studies in the field and 

 in sea water systems showed that blue crabs 

 consumed quahogs and other bivalves. 

 Thought to be a significant enemy of 

 bivalves.

The blue crab, because of its tolerance to 

 low salinities and its great abundance in 

 some estuaries, is discussed as an important 

 predator (even as early juveniles) on very 

 young benthic fauna.

 New England. U.S. Department of the Inte-

A short account on the crab industry of 

 New England. Relatively few blue crabs are 

 included in the catch because this species 

 reaches the limit of its range in Massa- 

 chusetts.

Responses of crustacean chemoreceptors to

 chemoreceptor activity was demonstrated

Blue crabs were abundant in the bays of 

 the survey area on the Texas coast and 

 occurred over a wide chlorinity and tem- 

 perature range. Some crabs were caught at 

 dissolved oxygen concentrations of 1.6-2.0 

 p. p.m.; at lower concentrations, they were 

 observed on floating objects or ashore.
