Aquaculture production of hatchling Hawaiian Bobtail Squid (Euprymna scolopes) is negatively impacted by decreasing environmental microbiome diversity.

ABSTRACT:

Aims

The Hawaiian Bobtail Squid (Euprymna scolopes) is a model organism for investigating host-symbiont relationships. The current scientific focus is on the microbiome within E. scolopes, while very little is known about the microbiome of the tanks housing E. scolopes. We examined the hypothesis that bacterial communities and geochemistry within the squid tank environment correlate with the production of viable paralarval squid.

Methods and results

Total DNA was extracted from sediment and filtered water samples from 'productive' squid cohorts with high embryonic survival and paralarval hatching, 'unproductive' cohorts with low embryonic survival and paralarval hatching. As a control total DNA was extracted from environmental marine locations where E. scolopes is indigenous
