Diffusion tubes: a method for the mass culture of ctenophores and other pelagic marine invertebrates

The culture of pelagic marine invertebrates, especially the ctenophore , has been demonstrated in past studies dating back to the 1960s; however, the mass culture of delicate pelagic invertebrates has remained elusive. By using a pair of acrylic tubes and enabling water diffusion between them, we ha...

Description
Summary:The culture of pelagic marine invertebrates, especially the ctenophore , has been demonstrated in past studies dating back to the 1960s; however, the mass culture of delicate pelagic invertebrates has remained elusive. By using a pair of acrylic tubes and enabling water diffusion between them, we have been able to reliably and cost effectively mass culture several genera of ctenophores ( , , , and ), one species of siphonophore ( ) and one species of larvacean ( ). The simple, compact method is effective enough to support two permanent exhibits of ctenophores at the Monterey Bay Aquarium while minimizing live food culture requirements with the potential to support further investigation of pelagic marine invertebrate ontogeny, ecology and genomics.
