 ing period during the summer months or two breeding seasons 

 during the year. The present study did qo1 extend through the 

 entire year and so we have no information concerning the status 

 of the shrimp during the winter months. H is hoped that the 

 investigation may be continued until this and other points may 

 be elucidated.

At present, without more complete information concerning the 

 life history of this form it would hardly seem advisable to adopt 

 regulations for its protection. .Most of the agitation for such 

 protection has been based on the plea thai as young individuals 

 were caught during the summer months fishing at that time 

 should be prohibited. Without more detailed informal ion con- 

 cerning the place and actual times of breeding intelligent steps 

 ,.,,,, not be taken. II' it is found that the shrimp Laj their eggs 

 in the deeper water, they are oo1 in much danger of being over- 

 fished at that time, provided that- the supply is oo1 lowered by 

 fishing below the point where they are able to keep the supply 

 constant by normal reproduction. This point secerns to be a 

 vital one in all animals of commercial importance to man. By 

 the constant inroads upon the natural supply the number of 

 breeding individuals is gradually lowered until there comes a 

 time when the supply begins to decrease. When that point is 

 reached active steps are usually demanded to protect the com- 

 mercial interests, bi some cases ii has been necessary to entirely 

 prohibit the catching of certain forms for a period of years in 

 order to permil them to recuperate by natural means: yet a1 

 best this is but a temporary advantage and some more efficient 

 safeguard is needed. In the case of the oyster industry this need 

 was me1 by the bedding method-, some of the fishing industries 

 are possible today by the artificial rearing of the young fish. At 

 present our knowledge of the habits of the shrimp are too incom- 

 plete to prophecy just what method would be mosl beneficial in 

 meeting the demands made upon them, and it is hoped that no 

 restrictions will be adopted until this information is supplied.
