Studies on the biology of planktonic coelenterates / by Mary Needler Arai.: Fs52-4/1223E-PDF

"The 1970 survey of plankton in the Alberni Canal indicated the presence of various hydromedusae and ctenophores including Aeguorea, Sarsia, Phialidium, Aglantha, Rathkea:, Eutonina and Pleurobrachia. Sarsia, Phialidium and Pleurobrachia were particularly abundant and have therefore been most.extensively investigated in the present series of studies. The research in the summer of 1972 has taken two main directions which will be included in this report. 1. Observations on the behaviour of coelenterates with reference to discontinuity layers. 2. Measurements of oxygen consumption of hydromedusae. Preliminary exploration was also made of the kinds of biological information on coelenterates which can be derived from plankton hauls carried out by other members of the Environmental Research Group in connection with productivity studies"--Introduction, page [1].
