CryoPlankton
Large

Knock out the low performing AF artemia!

CryoPlankton Large is the 1st stage offspring (nauplius) from Semibalanus balanoides. Length 320µm/Width 150µm, and it will replace your non-enriched artemia with a natural nutrient bomb! With no need for enrichment, these nauplii will prepare your fish larvae for long term optimal growth like never before.

Our customers have successfully replaced rotifers with CryoPlankton Large as the very first feed for seabass (Dicentrarchus labrax) and yellowtail kingfish (Seriola lalandi).

CryoPlankton
Small

Replace rotifers with a biosecure off-the-shelf alternative!

CryoPlankton Small is the 1sth stage offspring (nauplius) from Balanus crenatus. Length 200µm/Width 100µm, and it will replace the need for keeping a rotifer culture at your hatchery. Moreover, it packs a nutritional value and comes with a biosafety your rotifers will be envious about!

And, you will always have a live, off-the-shelf product ready, giving assurance and consistency to your production.

What CryoPlankton will do for you

Our customers experience earlier weaning to dry feed when using CryoPlankton. Weaning from Small to Large is done in a day and increased growth and stress tolerance associated with CryoPlankton, weaning to dry feed can be done earlier than with a traditional protocol.

Several scientific studies show positive long-term effect, increased growth and improved FCR and SGR in sea cages when fish larvae is given marine nauplii early in life.

Frequently asked questions

Will cryopreserved barnacle nauplii survive and settle in my hatchery?

Definitely not. The nauplii are alive and show strong vitality in stage 1, but have difficulties in developing further. We have been feeding the nauplii all kinds of high-quality algae, but they do not have the capacity to molt six times until they reach a stage where they can settle as cyprids on a surface. Customers have been using CryoPlankton since 2016 without any proof to the contrary.

Is it safe to handle liquid nitrogen at the hatchery?

Wear gloves, protect eyes and bare skin before handling the CryoPlankton. Proper training will be given by Planktonic as well. Dewars with nitrogen should be stored in a ventilated area.

What’s the shelf life of CryoPlankton?

You can store CryoPlankton for an infinite period of time, as you long as you compensate the evaporated liquid nitrogen.

How often do you need to refill dewars with liquid nitrogen?

50 days after being dispatched from our production plant. Normally, customers spend all the CryoPlankton before the liquid nitrogen is depleted in the dewar.

How do I return the dewars after use?

Give us a call, and we’ll come and collect them.

What’s the nutritional components in CryoPlankton that makes it superior over rotifers/Artemia?

Essential fatty acids are bound to the phospholipids and not in the triglycerides as with rotifers and artemia. Fish juveniles utilise phospholipids far more efficient than triglycerides. Also other components in CryoPlankton such as taurine is of major importance for the development of the fish larvae.

What would be the effect of adding cryoplankton to current live feed regimes as a partial replacement or booster feed?

You don’t get the full cryoplankton effect by doing this, but big improvements are seen in growth rate and disease resistance from the very first. These improvements continue into later life stages.
