Green Water

Blending

The frequent addition of algae to rearing tanks, the ‘pseudo green-water’ technique, has been demonstrated to be beneficial during the early larval period by several researchers. (Papandroulakis et al., 2002; Naas et al., 1992). Nannochloropsis (Marine Chlorella) has been widely used for creating green-water with good results.

Pseudo green-water larviculture has a number of advantages when compared with ‘clear-water’ larviculture:

  • Increased survival rate (by up to 50%),
  • Improved pigmentation, growth rates and swim bladder function,
  • Stabilization or improvement of water quality,
  • Increased ‘capture perception’ by the larvae,
  • Improved immunological development,
  • Reliability.

Greenwater Technique...

... with PhytoBloom Green Formula – the easiest way

Green
  • Shake the container to resuspend.
  • Take the necessary volume.
  • Dilute to desired concentrationwith sea water.
  • Keep the remaining product in the fridge.

...with PhytoBloom Ice – the cheapest way

Ice
  • Take the necessary amount (while frozen, the product is easily cut with a blade).
  • Place the biomass in a bin containing sea water and an air tube.
  • Let air bubble (medium to strong) for 5 minutes. Same result is achieved with a blender.
