This project concerns intensive hatchery production of great scallop and flat oyster spat as opposed to collecting natural set juveniles. In hatcheries spat may be produced continuously if predictable procedures for conditioning of broodstock and larval rearing exist. Hatchery production of bivalves during autumn and winter (outside natural spawning season) is a challenge, but necessary to keep market shares and ensure sufficient seed supply to European growers on a year-round basis, i.e. early in the season. The SETTLE project focuses on key events during hatchery production of flat oyster (Ostrea edulis) and great scallop (Pecten maximus) which are species native to Europe.
The overall objective is to foster year-round production of spat in hatcheries by controlling gonad development and maximise larval metamorphosis and settlement. Flat oyster and great scallop are both highly valued and sought-after products on the European seafood market, but insufficient numbers of high quality seed severely hamper aquaculture development of this sector.
To solve the seasonal problems the SETTLE project will identify environmental factors leading to successful off-season broodstock conditioning (manipulation with feed, light and temperature), reveal effects of conditioning and other biological processes on settlement and optimise existing culture methods and technology. Expected outcomes are:
1.               Procedure for conditioning oyster broodstock in winter
2.               Culture technique for maximized settlement of flat oyster
3.               Procedure for conditioning scallop broodstock in winter
4.               Culture technique for maximized settlement of scallop
Bivalve hatcheries (SMEs) in Spain, France, Ireland and Norway are participating in SETTLE. By extending their hatchery production season and obtaining new knowledge and technologies the SMEs will increase the available number of flat oyster and great scallop spat. A quantity and value increase 5-10 times of today’s level is anticipated within 5-7 years. This will strengthen the competitive position of the SMEs and increase the shellfish production in Europe significantly.
The SETTLE project belongs under the 7th framework programme of the European Community (EC), Specific Programmes 4 – Capacities, Research for the benefit of specific groups, Research for SMEs. The University of Bergen in Norway act as the project coordinator. The project is of two years duration starting October 2008. The total budget is EUR 1,853,680 with EC contribution EUR 1,406,400. SETTLE has six work packages and 290 person months will be dedicated to the project.
