The maximum value was reached early in March 1975, and was followed rapidly in mid-March by another sharp post-spawning decrease. The gonosomatic ratio pattern for males was similar to that for females, but monthly differences were not as pronounced (Fig. 2, Table 1). Maximum development in 1974 was in January, followed by a summer decline and a fall increase, and values.
