The problem of egg size variations in the Argentine anchovy Engraulis anchoita has been studied in relation to the different seasons of the year and to the different spawning centres within the geographical area. It has been stated that there exist significative differences in egg dimensions between the northern and the southern spawning centre of the reproduction area. Taking into account other biological characteristics of the anchovy from both centres it is suggested that these variations could indicate that the spawning stock is divided into two main genetic groups. It has been found that the average size of anchovy eggs decreases as the spawning season progresses.
