20 Octopus maya
microorganisms in cephalopods. In this review, they reported several bacteria that
affected O� maya, including some from Vibrio spp. In culture conditions, high mortality could be observed when low-quality food was offered. Therefore, food supplied to O� maya juveniles must be clean and fresh. Other environmental factors
can provoke stress and in consequence make octopus more vulnerable to bacterial
infection. In outdoor ponds, temperatures around 15 °C provoked stress in 1 g WW
juveniles and at the same time V� alginoliticus infection. To avoid that, we used an
immersion heater to increase the temperature of the pond to 18 °C. Occasionally,
infections with Vibrio spp. are observed, mainly when the marine food is contaminated. In such situations, oxytetracycline was used; a bath of 2 mg L
− 1
for 30 min
during 7 days was effective against this type of infections.
