When the tickness of zeolite layer in filter 1 was reduced to the original 5 cm, squid survival became similar to that of our previous experiment. Thus, improved survival was a function of zeolite. To further test the effect of zeolite upon survival, we tried three runs of 15, 12, and 5 squid, respectively, with filter 1 containing 80 kg zeolite. Average survival was days (thin sol

To further test the effect of zeolite upon survival, we tried three runs of 15, 12, and 5 squid, respectively, with filter 1 containing 80 kg zeolite. Average survival was days (thin solid line in Fig. 3). Thus, 80 kg zeolite may be harmful to the squid. Probably, there exists an optimum amount of zeolite for survival. In our system, 20-40 kg of zeolite appeared optimum among amounts tested : 5, 20, 40, and 80 kg. Maintenance of fed squid Longer maintenance of squid (Dorytcitthis blcekcri) by feeding them was tried February through April, 1979. Ten squid (one female, the rest male) were placed.
