This species enters the bay in large numbers during February and 
March. Many are then caught with seines and with hand lines. 
Though the bulk of those entering the bay may not remain it is always 
more or less abundant. 
Ripe individuals of both sexes were abundant in April and the eggs 
were procured with surface nets. 
As stated under the head of Sciana saturna, the eggs and larve of 
these two species resemble one another greatly. The color cells in this 
species do not appear till the gastrula covers two:thirds of the yolk, 
and on hatching there are a few more color cells on the tail than in 
Scicena.

that reached by the ordinary seines.
