Autor: Jianguang Qin, Ahmed E. El-Ghobashy, Nagwa Abdel-Aziz, Mohamed Moussa Dorgham, Wael S. El-Tohamy

Publikováno v: Aquaculture International. 29:105-125

Four algal species (Isochrysis galbana, Chaetoceros muelleri, Tetraselmis suecica and Nannochloropsis oculata) were tested experimentally as food for the calanoid copepod Gladioferens imparipes, which could be a potential food for marine fish larvae.
