The hatchery-reared juvenile production and label-release-recapture experiments will beconducted in this plan. The results will be apllied to assessing whether the seeding isviable tool for population enhancement. At the same time, the maintenance andreproduction of Octopus spp. will be conducted too. The tank system, diet, growth,mature size, spawning season, spawning behavior, embryonic development, hatchingand larvae rearing will be studied. The results will be apllied to juvenile production forculture and population enhancement and to understanding the complete life cycle foridentification.
