The word Vivier is derived from the French word for live/life: Vive. The key aim of these systems is to keep your shellfish stock live and in good condition for market.

As you maybe aware, shellfish are very sensitive to changes in water conditions, light, temperature and dissolved salts. So to improve their survivability outside of their normal marine environment, it is crucial to get these conditions balanced. Oxygen and toxins levels must be monitored and controlled with pumps and filters, whilst temperature is controlled by thermostatically controlled refrigeration systems.

What makes this process all the more interesting is that each species has slightly different tolerances. Browns are fairly tolerant , whilst Velvet Crabs are highly susceptible to toxins, temperature and low oxygen levels. Stress rapidly kills creatures if they are not kept under suitable conditions.

The whole point of a vivier system is to keep the stock alive once removed from their natural environment as the quality of shellfish "meat" degrades rapidly after death.They do this by maintaining the water conditions at close to an ideal as possible. Circulation pumps maintain a steady flow of clean, areated water throught the tank system, whilst thermostatic refrigeration controls water temperature within the ideal range for the stock. Bio-filters, mechanical filters, UV/electrostatic and ionic exchange filters are employed to remove toxins from the water and reduce the risk of toxin shock in the stock. Monitoring systems warn of any mishap whilst back up systems and batteries offer a level of insurance in case of power or system failure.


Vivier systems in static shore side locations are fairly straight forward to produce and maintain as there is usually a ready supply of fresh sea water available; if a catastrophic system failure occurs, a flush of clean water can help save your valuable stock.. On the road, we are in a different situation. There is no ready supply of water or alternative power for pumps and filters; the system can be provided with a custom fast flush facility in the case of a toxicity warning. Obviously you must have access to clean salt water. It also has to be built to last and handle the punishment of hours on the road whilst keeping conditions in the tanks stable and habitable.

We have been designing these systems for over 20 years now and we feel we can offer you a system that will handle both the punishment of the road and improve the living conditions for your stock so that it arrives in good condition at the journeys' end..
