Abstract

Egg capsules of Uroteuthis sp. obtained from sea off Visakhapatnam were maintained in 1 t black FRP tank in 35 psu provided with gentle aeration. The egg mass consisted of two strings of viable egg capsules. The total number of capsules in the strings was 1288. Strings were suspended in the tank to be submerged in the water. The string might be of different batches of egg laying or laid by different females. The capsules were observed to be viable with embryos moving inside the capsules. Water level was maintained at 70 percent of the tank providing a gap from above. They were maintained in black tanks with mild light regime covering half portion of the tank with black cloth.
