New Zealand researchers have helped remove a bottleneck in octopus aquaculture which means that incubation of eggs are achievable even in the absence of maternal care. As a result, it is expected hatchery production will be more efficient in order to supply commercial aquaculture. Octopus farming is potentially very lucrative, however attempts to develop the sector have been hindered due to the previous lack of hatchery technology. The researchers recorded success when hatching of over 90 percent using upwelling incubation systems with added aeration. This is compared to a 10-40 percent success rate in systems without aeration.
