AbstractTo study the effect of feed ration on rearing and nutritional conditions of Octopus maya juveniles (7-10days old), two groups of octopuses were fed on 10% and 30% rations, using a crab paste agglutinated with gelatine, when compared to another control group fed ad libitum on crab muscle tissue. The agglutinated diet was well accepted by the octopuses at this early stage. When considered together, the marginally higher survival of the 30% group and probably higher levels of the other rearing performance parameters (growth and feeding rate) indicate that this feed ration is more adequate than a 10% feed ration for rearing O. maya under these conditions. Octopuses fed 30% also generally showed higher total energy per gram of arm tissue and oxygen consumption, as well as different proteolytic activity. In addition, the mentioned nutritional differences influenced by the feed ration were found to be statistically correlated to the promoted growth and the end survival and feeding rates. © 2010 Blackwell Publishing Ltd.
