Abstract

The eggs spawned by Mctupenucris dobsoni in brackishwater salinities via. 22.26,28 and 30 ppt were hatched and the nauplii reared further up to protozoea stage and the possibility of completion of larval (naupliar) development in bnckishwater salinities was studied. The results of 10 trials in different salinities indicate that the naupliar development can be completed in salinity as low as 22 ppt and the time taken for completing the naupliar stages I. 11 and 111 is not affected by variation in salinity. The total time taken to complete all the six naupliar stages however gradually increased (31 - 49.5 h.) with increase in salinity under normal water quality conditions.
