not die in such captivity; they will and they do in tanks sup- 

 plied with plenty of fresh sea water. 



The following graph from Sea and Shore Fisheries Bulle- 

 tin 11 shows the death rate in fresh natural sea water. No 

 lobsters died in the first seven days. But thereafter the 

 death rate rose somewhat until after twelve days the mor- 

 tality sharply increased. All fifty lobsters in the test were 

 dead in thirty-two days. The water was cooled to 45°-50°F. 



The bulletin of Sea and Shore Fisheries (1960) "The 

 Storage of Live Lobsters in Reeirculated-Refrigerated 

 Tanks," by Phillip L. Goggins, corroborates many of the facts 

 given above. Its formula for artificial sea water is the same
