Abstract

Two series of experiments were conducted to relate surfacing behaviour and post-embryonic development in the air-breathing fish Channa s(riatw;. When prevented surfacing, the duration of survival on aquatic breathing alone decreased from 15 .6 hr in 7 mg fry to 8.8 hr in 0.75 g fingerling; when given free access to air, the surfacing frequency was the most erratic ( 1235 ± 823 (SO) limes/day) in the former and became regular (1323 ± 114 times/day) in the latter.
