MIGRATIONS OF COD 
19 
states that during the winter of 1927-28 the first cod was taken October 8 and the 
first fair catch on the 24th. Good catches of cod were made the first two weeks of 
January, which was considered unusual for that period. 
In order to learn something of the movements of the cod after they migrate from 
Nantucket Shoals to western Long Island, fish were tagged on the Cholera Bank 
during November, 1927 and 1928. The recapture records are given in Tables 
10 and 11.

These results may he summed up as follows: 
1. No recaptures were reported from the Cholera Bank proper, although the 
fishing there was very intensive for weeks after the fish were tagged. Accordingly, 
as this happened both in 1927 and 1928, we can conclude that the schools of cod 
which arrive on the bank in the fall do not remain there for long but move on to other 
grounds. 
2. Even though the same individual cod do not tarry long on the Cholera Bank 
in the fall, all of them do not necessarily move far, for a number of marked fish 
were recaught later in the winter 10 to 20 miles away. This is illustrated by fish 
A, B, C, and E listed in Table 10 and by J and K in Table 11, shown in Figure 5. 
3. Some of the cod which reach the Cholera Bank in the fall continue their mi- 
gration southward. This is shown in Figure 5 by fish D and H. 
4. The fish F and G (Table 10 and fig. 5) went eastward and are discussed 
on page 33. 
The percentage of recaptures resulting from the cod tagged on the Cholera Bank 
during November, 1927 and 1928, amounted to only 4.8 and 2.2, respectively. This 
was smaller than what might have been expected in view of the very intensive sport 
fishing that was carried on there during and directly after the marking experiments. 
On the face of this it would seem that most of these fish moved away very soon after 
being tagged and, as the number tagged was small, we could expect very few of them 
to be reported from the many square miles of cod grounds which extend to the east- 
ward and to the southward. 
With regard to the Cholera Bank cod taken in Delaware Bay in January, 1929 
(Table 10), it is very likely that this fish returned to southern New England during
