A New Generation
of Marine Live Feed
We are developing oyster technology as a natural marine live feed for fish and shellfish larvae
The Organism
Trochophore
A trochophore is the oyster’s first free-swimming larval stage, formed approximately 18–24 hours after fertilisation. Trochophores are small, nutrient-rich and naturally active in the water, it combines several characteristics that make it particularly interesting as a live-feed organism for marine fish larvae.
Unlike a formulated feed, the trochophore is a complete living marine organism. It naturally contains phospholipifs, sterois, proteins and marine fatty acid, and can stimulate the fish larvae’s natural hunting behavior.

From Oyster to Feed
Turning Hatchery Expertise
Into Marine Feed
Ostrea’s trochophores are produced through controlled oyster reproduction. From broodstock (Magallana gigas) and fertilisation to quality control, filtration and cryopreservation, the process is being developed for controlled and reproducible production.

Separation of trocophores from seawater
Cryopreservation
Controlled cryogenic freezing system used for the cryopreservation of trochophore larvae.
