  Abalone production started first in Japan more than 50 years ago.
In China abalone aquaculture was initiated in the late 1980s. Today
China leads the world in abalone production.
Outside Asia abalone aquaculture
has been initiated in several
countries; Australia, South Africa,
USA, Chile, Mexico, New Zeland,
France, Spain, Ireland,…

Abalone can be cultured using a
variety of methods depending on;
investment, capital, country

         Worldwide more than 15 species are now being commercially
         cultivated with over 1000 individual farms with production
         ranging from less than a ton to over 200mt.
 The ormer Haliotis tuberculata is the           Haliotis rufescens      USA, Mexico, Chile
 only European species that reaches a            Haliotis corrugata        USA, Mexico
 large enough size to be harvested.               Haliotis fulgens         USA, Mexico

                                                Haliotis diversicolor      Japan, Taiwan
The interest in ormer culture has been             Haliotis discus             Japan
increasing due to high export values to            Haliotis midae           South Africa
Asia and because international commerce

is easier.

 Objectives of WP.7

      Evaluate the technical and economical performance and
risk factors of a sea-based cage system in an EU context.

      Establish the range of sea-based production systems and
their relative technical and economic features.

       Investigate the economic, technical and legislative
limitations to food source availability from seaweed in terms of
harvesting and culture.

     Make a comparison of recirculation systems vs sea cage

     Provide guidelines to reduce environmental impact of
abalone farming and improve sustainability.

       How to reach these goals?

         Abalone culture in a recirculation system

Culture trials in sea cage systems

        Four experimental sites.

        Three different culture systems.
        Two seed sizes.
        Three experimental densities.

        Feed control.

        Economical evaluation.

                  TO SUM UP

   These trials allow:

 Test different culture systems, analysing their technical and
 economic strengths and weaknesses in different
 geographical and environmental contexts.
Record seasonality/system variations in growth rates and

Indentify sustainable seaweed sources and their sustainable
collection methods.

Do an economical analysis.

Evaluate the environmental impact.
