Development of an integrated environmentally friendly polyculture of abalone, finfish and seaweed in a land based facility

Objective

The world markets for abalone is strongly under-supplied. Therefore, abalone prices have increased rapidly, creating incentives for the more expensive land-based culture. However, SMEs culturing abalone in land-based systems have faced several obstacles mainly in obtaining sufficient quantities of nutrients seaweed without causing negative environmental impact to natural stocks. The quantity and quality of seaweed as well as proper tank design together with effluent regulations has limited production to date.

The development of a self-sustaining, environmentally friendly, intensive system for the integrated culture of marine organisms in cold as well as warm water was based on research undertaken by two R&D institutes in Ireland and Israel. The system produced commercially valuable finfish (sea bream and grouper) and recycled their excretions through seaweed biofilters, which removed most pollutants from the water, and whose protein-rich yield can feed the abalone culture. The commercial culture of the seaweed-consuming abalone converted this low-value by-product into a high-value commodity, which would generate substantial returns. The development of a new tank design allowed much higher intensification, which is abalone stocking density, than is currently possible.

SMEs that implemented the developed technology were able to gradually enter this Niche and produce high quality seafood products at relatively low costs using fully controlled independent Green systems that will guarantee long term profitability.
