tailed results of fifteen tests in transporting alewives in 10- 

 gallon cans in a Ford car by one man are shown in the follow- 

 ing table. Alewives can be carried a maximum distance of 48 

 miles, provided they receive proper aeration, are not over- 

 crowded, and the temperature is not too high. The effect of 

 temperature is shown by 17 per cent success at 81 F., as 

 compared with 100 per cent at 65 F., in transporting alewives 

 from Bournedale to Hingham. The result of overcrowding 

 with 15, instead of 6, per can is shown by 27 per cent success, 

 and lack of aeration, by 14 per cent. 



Results with larger quantities, when large cans and a truck 

 were used by the fish salvage crew in transplanting alewives 

 from Bournedale to Long Pond, were less satisfactory, owing 

 to the difficulty in aerating large numbers of cans, and to the 

 warm weather. 



Artificial Hatching. The ideal method of propagation would 

 be to plant artificially hatched alewives, and sufficient prelim- 

 inary work has been carried out along this line to indicate that 

 commercial hatching is feasible.
