Where are you in the process?
Different hatcheries arrive at CryoPlankton from different starting points. Choose what fits where you are now.
Still assessing whether CryoPlankton is relevant to your species or hatchery setup. Looking for answers before committing to a conversation.
Ready to understand the product range, what changes operationally if you adopt CryoPlankton, and which format is relevant to your larval stage and species.
You have enough context. You are ready to discuss protocol fit, understand what a phased implementation would look like for your operation, and talk through the practical next steps with the Planktonic team directly.
Enquiry form
The more context you share, the more useful the first discussion will be. All inquiries are reviewed personally before any response is sent.
What to expect
01
Before any call, we read your inquiry carefully. The first discussion will be relevant to your species, your current live feed protocol, and what you are trying to improve. That conversation shapes everything that follows.
02
CryoPlankton is a natural live feed with exceptional nutritional value, and the results across warm and cold water marine species alike continue to make the case for its place at the start of every hatchery protocol. Our team can also support analysis of trial outcomes, drawing on years of hatchery experience to surface less-obvious benefits beyond the standard KPIs.
03
If the fit looks right, we will walk you through how to run CryoPlankton in parallel with your existing system, allowing you to evaluate results at your own pace.
04
Adoption is a transition, not a switch. We support hatcheries through each phase at a pace that suits your operation.
Exploring your options
Most hatcheries have similar early-stage questions around handling, storage, species fit and what changes operationally.
The FAQ page covers the questions hatchery managers ask most, with straightforward answers. Here is a glimpse of FAQs.
The four products share the same nutritional foundation- natural marine plankton, with DHA and EPA in phospholipid form, no enrichment needed. The primary differences are size and form. Cryo-L (Semibalanus balanoides, 320 µm) is the larger-size format, used across marine fish and crustacean hatcheries from first feeding through to weaning. For species with larger mouth gapes at first feed can start on Cryo-L directly. Cryo-S (Balanus crenatus, 200 µm) is the smaller-size format, designed for marine species whose larvae cannot yet ingest 320 µm prey at first feed. It covers the earliest feeding window, with hatcheries typically transitioning to Cryo-L as larvae develop. Many hatcheries use both across the larval feeding window. Cryo-Micro (70 µm) is the smallest-size format. It is designed for the earliest stages and has shown strong uptake in sea bream, ballan wrasse, cod and shrimp larvae. i-Cryo is an inert, frozen alternative to Cryo-L, for hatcheries that prefer a format storable at −20 °C without dewars. Shelf life is three months at −20 °C, or unlimited in liquid nitrogen.
CryoPlankton is stored in liquid nitrogen dewars. The product remains viable indefinitely as long as the liquid nitrogen level is maintained. The primary storage requirement is ensuring the dewar does not run dry. Dewars should be kept in a well-ventilated area.
CryoPlankton can be stored indefinitely, provided the liquid nitrogen level in the dewar is maintained consistently. In practice, most hatcheries work through their supply well before the nitrogen requires replenishment.
Traditional rotifers and Artemia store essential fatty acids inside triglycerides, whereas CryoPlankton contains them naturally inside phospholipids. Marine fish larvae possess an evolutionary adaptation that allows them to process and absorb nutrients bound to phospholipids far more efficiently. Furthermore, CryoPlankton naturally provides optimal, un-enriched concentrations of vital proteins (67g/100g dry weight) and critical micronutrients like taurine, which are structurally deficient in standard live options like AF Artemia.
