Stage 1. Build up stock culture (winter)

These are the critical life parameters, but for hatching the temperature is the most important.

• Food: powdered dried spinach / spirulina powder
• Photoperiod - 14 hours (08:00 hrs - 22:00 hrs)
• pH: optimum = 8
• Temperature curve: max. = 32 deg C, min. = 12 deg C
• Aeration.

Starter cultures of Moina macrocopa, Hylalella azteca, Streptocephalus siamensis (January - March 2021)

Stage 2. Sub-culture and move to laboratory

5 sub-cultures of Moina macrocopa were set up in the chemistry lab in DCU awaiting bought-in carboys for culturing containers.

The same conditions were applied once the equipment was acquired.
