![]() The buoy is one of the first devices of its type in France, but after its first contact with this new technology, the shellfish farming sector is already thinking of measuring additional parameters, such as chlorophyll and pollutants. The Auray-Vannes FLAG played a key role by supporting the application for CLLD funding and coordinating the project partners. This would in turn lead to more efficient spat collection and increased oyster production. This would allow them to analyse the changes in the oyster’s natural environment and work out the best time to collect the spat. Methods of spat collection commonly practised: Dependable and consistent supply of seed is an essential prerequisite for viable aquaculture industry. Hence, the Regional Shellfish Farming Committee of South Brittany submitted a project proposal to install a high-frequency multi-sensing buoy to gather data on these parameters. It does not occur in the open sea but inside the. Studies carried out locally by the national marine research institute Ifremer linked environmental conditions, such as temperature and salinity, to oyster spawning, which directly impacts spat settlement quality and quantity. Oysters from the genus Ostrea differ from the other oysters by fertilization. Oyster spawning is becoming less predictable, which is making it harder to collect spat for cultivation. ![]() The wild oyster stocks, the main source of spat for breeding this species in captivity, are increasingly threatened by climate change and human action, which worsen water quality and give rise to large temperature fluctuations. In France, the two main flat oyster collection areas are Brest Bay and Quiberon Bay, both in Brittany. kept feces and pseudofeces from collecting around the individual oysters. ![]() Home Nursery Oysters Mussels Clams Scallops Packaging Multi-Species Marine Traps Finfish Netting Fencing Used Aquaculture & Processing Machinery. Forms of Oyster Catcher optimized for spat collection can be used in hatcheries or appropriate natural environments as a biodegradable oyster shell. This creates tiny larvae, which after 2-3 weeks grow legs and ‘settle’ by attaching themselves to a solid surface, where they are known as ‘spat’. Oyster cultivation products, from spat collection to harvesting, including deployment and grow-out gear, oyster nursery equipment, and packaging equipment. Oysters breed by releasing their eggs and sperm into the water, where fertilisation takes place.
