Ostrea edulis, Other Bivalve Species
Aquaculture, Seed Production, Oyster Supplier (Grow-out, Wild Fishery)
We have been growing Ostrea edulis for years now in Croatia to be sold as fresh to the restaurants and directly to final customers. We are very interested in keeping our growing location disease free and to work on projects that will improve the biology and technology of growing flat oysters. At the moment we collect our spat from the wild on collectors but would like to get access to a hatchery or to build our own in the near future.
I have almost 30 years of experience in studies of marine bivalves, both from the perspective of their aquaculture and from their use in environmental research. I have extensive experience in bivalve culture techniques from broodstock, larval culture and seed, as well as in the assessment of physiological rates that integrate the energy balance in order to estimate their energy potential or SFG (scope for growth). I have also been interested in the nutritional requirements and digestive biochemistry of different species of bivalves, mainly during growing, in order to develop alternative diets. I have been involved in pollution and toxicological studies using bivalves as biomonitors and species model. Actually, I am promoting, together with almost 20 scientists from different disciplines, the recovery of the environmental quality of the Mar Menor lagoon (SE Spain), severely affected by eutrophication, by the restoration of the flat oyster beds.
Our goal at OSH is to provide disease free O. edulis spat of the highest quality for habitat restoration and grow out purposes. We utilise high intensity influent and effluent sterilisation as well as a number of RASs and novel spawning and setting systems to achieve high levels of biosecurity.
We produce Ostrea edulis for both the table and restoration market on our disease free farm in Wester Ross, Scotland. We have been involved in the on growing of the 'Native' since we started the farm and as a result have a great respect for this little creature and appreciate the challanges involved in their cultivation. We are a key supply chain partner of the Glenmorangie DEEP project and are working closely with that project to deliver significant volumes of part grown stock for relaying in the Dornoch Firth. We are also greatly interested in preservation of existing wild Scottish population and are working with others to identify, protect and enhance these.
Breeding flat oysters for Bonamia resistance in Denmark
I have worked with spatting ponds for 8 years and have found it works really good for flat oyster production and spat on shell for bottom culture production I am interested in spatting ponds and bottom culture and ways to improve that Restauration is in my view bottomculture without harvest, so my experience would translate very well for that.
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.

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.
A marine biologist with long history in oyster restoration and wild fisheries management. He developed and run a successful restoration project in Swansea Bay (Wales) which has reported early indications of spill over and recruitment. An advisor to UK Government agencies he has recently produced a number of advice documents and strategy reports. He is currently involved in restoration projects in Wales and Cornwall and has advised on a number of similar projects across the UK. Most recently he has developed a commercial oyster farm in Pembrokeshire which grows Ostrea edulis for restoration alongside a commercial crop of Crassostrea gigas to support the activity. The next step is development of spatting ponds to produce cost-effective native oyster seed.
