| description | The feeding behavior of juveniles of Notothenia rossii marmorata was investigated by the examination of stomach contents of three fish and by the field observation. Juvenile Notothenia came to the lighted area of shallow beach and fed on the swimming animals attracted by the light in late January of 1973. Amphipods, Chorismus. Neanthes and fish fry were mainly eaten in this order from evening to midnight. Juvenile N. rossii marmorata preferred the largest or larger animals in a prey population. Stomach contents of 64 juveniles of bottom dwelling N. rossii marmorata were also examined. Gammarid amphipods, algae and Ctenophore occurred frequently in the stomachs. The juvenile fish captured not only swimming animals but also swaying algae and Ctenophore. |
