Recirculating Aquaculture Systems
What we do not have is a system design that fits all requirements - such a system does not exist! Certainly many aspects of our systems are transferable from one application to another, but each location, species and even sales pattern will determine the detail of the design, which can only be realised by considering each project individually.
Sadly, correct emphasis on design is still often overlooked, and projects fail because of this. The aquaculture press regularly reports on bankrupt projects for one reason or another. Sometime the sale price or growth rate has been vastly overestimated, other times system design is fundamentally in error. If from failure to produce, it is often the case that the equipment used is not bad, it has just been specified wrongly and put together in the wrong order! We will only supply designs and equipment based on tried and tested performance, mostly at our own site in North Wales. Here we have produced sea bass, turbot and Dover sole, both fry and table fish. This enables us to continuously develop and test our systems and products and serves to illustrate the company design philosophy - balancing cost effectiveness and energy efficiency against environmental impact and the needs of the fish for optimal growth. We have recently completed a 4 year R & D program to develop cost effective systems and management protocols to grow L. Vannamei (Pacific White shrimp) in indoor super intensive 'ICE' RASs. (see Llyn Aqua Research Ltd).
Our programme of continuous research and development ensures that we remain at the forefront of current production technology and that the systems we supply have been thoroughly proven under commercial conditions.
We are currently working on projects in the UK, Australia, Greece and Ireland, Middle East and UK and provide a comprehensive consultancy service ranging from initial feasibility studies to total system design, project management, supply and installation.
