Orasay Edulis is based on the island of Barra in the Western Isles of Scotland. We take seed from disease free hatcheries and grow them using the latest aquaculture methods to get the best growth and survival. The waters around Barra do not have a population of edulis. We know this because neither divers nor dredgers have found live stock; there are no old shells turning up on our shores; our local Pacific oyster farm sees no settlement of edulis on either shells or on equipment. All of the above is very important for biosecurity reasons. We recently (July 2020) took in 100,000 O. edulis seed from Morecambe bay hatchery and have been growing them in suspended culture. Growth and survival has been good to date. We are happy to discuss supply of stock to meet your project's needs.
Atlantic Shellfish Ltd. has been breeding O. edulis since 1969, by using 22 breeding ponds in Cork Harbour, capable of producing 100 tonnes / year of marketable oysters. The ponds are used to produce spat, which are then grown and fattened in the North Channel of the harbour. The company mainly supplies the restaurant market, with fully grown, well graded oysters, packed to the customers need. Atlantic Shellfish also is running the Loch Ryan wild native oyster fishery in South West Scotland, which has a sustainable, natural production of O. edulis which is free from Bonamia. These are mostly harvested for the restaurant market also. The company has depuration tanks in London, and is able to supply the UK market overnight with O. edulis and C. gigas, along with exports from Heathrow.

On behalf of OSH, we are focused on the reliable production of disease free O. edulis spat. We utilise high intensity influent and effluent sterilisation as well as a number of RASs and novel spawning and setting systems to achieve this.

John A. Theodorou is a Shellfish Biologist (MSc University of Wales at Bangor, UK) specialized in Aquaculture and the Fisheries Product Quality Management & Marketing (Hull University, UK). His Ph.D. thesis referred to the Risk Analysis of the Mediterranean mussel farming (Ph.D. Gent University, Belgium). He has 20 years of hands-on experience in mussel farming and contributed to over 30 industrial and academic projects. As an expert, he contributed to the development of the FAO-GFCM Shellfish Demonstrative Centre in the Black Sea (2018). He coordinates 3 ongoing projects related to the: effects of the pearl oysters (i) and ascidians (ii) in shellfish activities and the (iii) use of aquaculture techniques for population recovery of the endangered Pinna nobilis. He is served as Assistant Professor in the School of Animal Production, Fisheries & Aquaculture, Patras University, Greece. He published 22 research papers and contributed to 13 book chapters of concerned actions.

The Mar Menor Oyster Project
I have more than 15 years of research experience in bivalve aquaculture (oysters, clams and razor clams). I have worked as researcher in academia and also as Research and Development engineer in private hatcheries. My research focus on the development of hatchery and nursery rearing for bivalves; embryological and larval development of bivalves; the impact of microbiology on hatchery culture of bivalves; nutritional and biochemical studies of diferent phases of bivalve culture; and bivalve selective breeding.

Solent Oyster Restoration Project
I am a marine biologist, specialised in Marine Ecology, currently PhD student at the Institute of Marine Sciences of Portsmouth (University of Portsmouth, UK). My research involves the hatchery production of the native oyster O.edulis as spat-on-shell for restoration in the Solent. I am investigating the genetic implications surrounding the employment of locally adapted broodstock from disease-affected areas, for the hatchery production of native oyster seed for restoration purposes, monitoring the genetic diversity and potential disease-resistance during the whole production process. I am also investigating the mechanisms of competitive exclusion of C. fornicata, assessing the factors responsible for the inhibition of O. edulis natural recruitment in the Solent. During my most recent work experience, I've been running an aquarium based experiment to investigate the role of microplastics as pathogen vectors. All my previous experiences include projects related to the biodiversity and conservation fields of study.
