Economically sustainable production systems. EC´s Seventh Framework Programme (FP7,2007-2013) in the grant-funded Capacities Programme- Research for the Benefit of Specific Groups. Galway-Ireland 19 - May WP 7. Sustainable Production systems Introduction 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 regulations,.. Fig. Global abalone production (FAO) WP 7. Sustainable Production systems 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. PRODUCTION SPECIES AREA 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 kamitschatkana USA, Canada Haliotis soremseni Mexico Haliotis ruber Australia Haliotis laevigat Australia Haliotis discus hannai Japan, China, Chile Haliotis gigantea Japan 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 Haliotis australis New Zealand is easier. Haliotis virginca New Zealand Haliotis tuberculata France, England WP 7. Sustainable Production systems 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 systems. Provide guidelines to reduce environmental impact of abalone farming and improve sustainability. WP 7. Sustainable Production systems 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. WP 7. Sustainable Production systems Culture trials Sites Channel Islands UK (Jersey) (Dorset) FRANCE (Plouguerneau) SPAIN (Galicia) WP 7. Sustainable Production systems Culture Systems ORTAC´s Strengths -good water flow -low cost -easy stacking and transport -robust Weaknesses -fixed mesh size -small size -need support -can foul -a 20 mm seed size is needed Servimar cages Strengths -easy handling -different mesh size -good water flow Weaknesses -not used before -need support -fragile France Haliotis cages Strengths -different mesh size -big size -easy access to the animals Weaknesses -not easy handling -big size WP 7. Sustainable Production systems Seed size 20 mm 45 mm Densities Low density Medium density High density WP 7. Sustainable Production systems Feed control Frequency Feeding rate Economical evaluation Infrastructure cost Operative cost WP 7. Sustainable Production systems 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 mortality. Indentify sustainable seaweed sources and their sustainable collection methods. Do an economical analysis. Evaluate the environmental impact. First results 20 mm seed 24.5 mm/ind 2.4 g/ind 30% 150% 45 mm seed 17.8 g/ind 46.5 mm/ind 50% 8% Thank you!
