COD EGGS IN MASSACHUSETTS BAY, 1924-1925 



277 



As haddock do not spawn in the inner parts of the bay, the concentration of early 

 cleavage stages on the Plymouth grounds indicates that considerable cod spawning 

 still was taking place there. 



Passing on to the late spring, Figure 8 again shows that spawning (haddock) 

 was taking place along the Stellwagen Banks in the outer part of the bay and that 

 there was still some production at Plymouth as well. There is also some indication 

 that the influx of eggs into Massachusetts Bay from north of Cape Ann had begun, 

 although less than 5 per cent of the eggs taken along the north shore were in cleavage 

 stages. 



DRIFT-BOTTLE EXPERIMENTS 



For positive evidence of the set, drift bottles were placed in various parts of 

 Massachusetts Bay in February and again in May. On the latter occasion the field 

 was extended to include Ipswich. One hundred and forty-one bottles were set out 

 during the year, and 49, or 34.7 per cent, were recovered. 



Of 90 bottles set adrift on February 6 and 7, 18, or 20 per cent, were found 

 within a few days along the inner arm of Cape Cod. (Table 6.) Four circled Cape 

 Cod, one being taken 29 miles east-southeast of Stellwagen Bank, 2 two on the south 

 shore of Nantucket, and one at Fire Island, N. Y. Four turned east, and of these, 

 three appeared in Nova Scotian waters. One had started on a similar course when 

 picked up 28 miles east-southeast of Cape Ann. On June 15, 1926, bottle No. 

 49 was reported from Lands End, Cornwall, England, where it had been picked up 

 on the beach 494 days after starting its journey. In all, 27, or 30 per cent, of 

 the bottles set adrift on this cruise were recovered.
