Start year 2008 End year 2010 Funding (€) € 1,853,680 Website https://cordis.europa.eu/project/id/222043 Summary At present, there is a real need in aquaculture to find a sustainable and cost-effective technology for efficient cleaning and disinfection in larval hatcheries. The current cleaning methods carry huge economic consequences. For example, farms have lower productivity and quality through reduced survival rates of cultured species due to regular bacterial outbreaks. As a result, there are lower revenues. Their maintenance costs are also very high because of regular mesh changing and man hours required for cleaning and disinfection. The current systems are not reliable as biofilms are never fully removed. Moreover, the present requirement for changing standpipe meshes up to two times per month result in the according cost and amounts of waste from discarded mesh.
The project is divided into six work packages (WP), with WP1 and WP6 focussing on administration and reporting, whilst the other four work packages describe the research work and goals for the project. These work packages are outlined below: WP2 (Oyster Conditioning) Goals: To successfully spawn European flat oyster during autumn and winter, controlling the broodstock conditioning process and identifying the effects of biological and environmental parameters on sex-change and/or conditioning; WP3 (Oyster Settlement) Goals: To stabilize and improve larval survival and settlement during the winter and autumn, by developing new techniques to maximise and synchronise settlement in the hatchery and revealing the effect of environmental parameters. Aim to validate Petrifilm for monitoring bacteriological conditions during larval culture, and to reveal effects of chemical cues and substrate on settlement; WP4 (Scallop Conditioning) Goals: To successfully spawn great scallop during autumn and winter, developing methods to synchronise gonad development during winter conditions and reducing conditioning time by optimising temperature and photoperiod. Aim to improve larval quality by optimising broodstock diet; WP5 (Scallop Settlement) Goals: To maximise and synchronise scallop settlement by developing harvest techniques for competent larvae. Aim to increase settlement by optimising the flagellate:diatom ratio in larval diets and by using chemical and biological inducers, as well as revealing the effect of light exposure on settlement.
