23.6 inches. One abundant size group is evident in this range, con- 
sisting of fish that are in all probability more than 2 years of age—that 
is, in their third year. The older groups are represented but scatter- 
ingly, and by the end of the fishing season a smaller size group also 
appears in moderate numbers. Starfish taken range in length from 
2 to 8.3 inches and consist of two distinct sizes, which in all probability 
are separate year classes. The group of larger fish is taken during 
June and July, and the smaller size becomes abundant in August, 
September, and October, during which time the larger fish are absent. 
Butterfish range in length from 2.4 to 8.3 inches and constitute but 
one clearly marked size group. Spots range in length from 3.9 to 
9.5 inches and are readily divided into two distinct size groups. 
The larger fish are more abundant in June and July and the smaller 
ones in August and September. Croakers range in length from 5.1 
to 15.8 inches, but, as has been noted in other investigations, are 
separated with difficulty into distinct size groups. It is probable that 
two major size groups can be distinguished, but from our records it is 
difficult to assign ages to these groups. All sizes of fish are taken_ 
throughout the season, but the larger fish are notably reduced in 
relative abundance during October.
