Oyster Aquaculture Production Systems
UNIVERSITY OF MARYLAND EXTENSION //////////// extension.umd.edu ///////////////////////////////////////////////////////////////////////////////////////////////////////////// EM- 7 | November 2019 //////////// Oyster Aquaculture Production Systems Growers have cultured oysters for thousands of years and used Many Factors will Influence the System You many methods to raise them. The methods are based on the Choose to Raise Oysters technology, materials, species, environmental conditions, labor and other parameters available in the area where oysters are Before making a choice, investigate as many different systems raised. as you can, keeping in mind the location of your farm, Some growers will let you visit their operation or you may be “You don’ t make money familiar with local farms already in production. Oyster farmers raising oysters; you make are often comfortable showing methods and equipment they money by selling them. ” use because they know that expanding production benefits the entire industry. As a longtime grower once said, “What makes While there are many methods used to raise oysters, not all are my company profitable doesn’t show up in photos – it’s the profitable for Maryland growers. Profitable operation is the most management of the business that makes it successful.” important part of a successful aquaculture business. As a grower, you should make decisions based on sound business practices.

Oysters produced specifically for the seminars are held throughout the year on such topics as half-shell or raw bar trade are often cultchless. They are production systems, business management and seafood produced by setting larvae on small shell pieces rather than technology to provide the training necessary for industry growth multiple animals on a single shell as is done for bottom leases. -
Aquaculture and Marine Protected Areas: Exploring Potential Opportunities and Synergies
Aquaculture and Marine Protected Areas: Exploring Potential Opportunities and Synergies To meet the Convention on Biological Diversity’s Aichi Target 11 on marine biodiversity protection, Aichi Target 6 on sustainable fisheries by 2020, as well as the Sustainable Development Goal (SDG) 2 on food security and SDG 14 on oceans, by 2030, there is an urgent need to reconcile nature conservation and sustainable development. It is also widely recognised that aquaculture significantly contributes to sustainable development in coastal communities and plays a vital role in ensuring food security, poverty alleviation, and economic resilience. In the framework of integrated management, the time has therefore come to identify the potential opportunities and synergies that can enable aquaculture and conservation to work together more effectively. CONTENT Understanding the various types of aquaculture and their potentialities ……………………………………… 3 The types of MPAs and matrix of interactions showing aquaculture & sustainability principles …… 7 Understanding aquaculture and MPA interactions …… 8 Towards MPAs and aquaculture compatibility and sustainability ……………………………………………10 Background In order to feed the world's growing human population, attention will need to increasingly focus on where the protein needs of the world will be supplied from. While capture fisheries have now reached a plateau of production, marine aquaculture of fish, shellfish and algae has been steadily increasing over the past decades and has become a valid option to make up the protein shortfall. However, one of the major constraints for the aquaculture production sector is the availability of, and access to space. In many coastal areas, competition with other marine activities is already high, mainly because the bulk of marine aquaculture is located close to the shore. -

Wild adult animals from a natural breeding area in Crassostrea gigas Spain showed an overall prevalence of detection of 87.5% between 2010 and 2015 suggesting an environmental OsHV-1 source of viral material uptake. Overall positive PCR detections were significantly higher in adult animals (p = Gene expression 0.031) compared to newly hatched paralarvae (62%). Prevalence in embryos reached 65%. Sequencing of In situ hybridization positive amplicons revealed a match with the variant OsHV-1 µVar showing the genomic features that distinguish this variant in the ORF4. Gill tissues from adult animals were also processed for in situ hybridization and revealed positive labelling. -

It draws heavily on the experience of others. So in that TTrespect, few of the ideas are really new. After all, culturing oysters can be traced back to the early Romans who found that broken roof tiles that had fallen in the water made good spat collectors. Since then, various cultures have modified those techniques, so that very little is new in this business — just a lot of adaptation and redesigning from the old ways. For purposes of this manual, oyster culture is distinguished from oyster restoration and rehabilitation. Oyster culture is a sustainable enterprise, requiring a shellfish lease from the state, and is a private, for-profit commercial enterprise. -
The NMFS Commercial Fishing & Seafood Industry Input/Output Model
The NMFS Commercial Fishing & Seafood Industry Input/Output Model (CFSI I/O Model) Prepared for the National Marine Fisheries Service (NMFS) by James Kirkley, Ph.D Virginia Institute of Marine Science August 2009 Executive Summary The NMFS Commercial Fishing & Seafood Industry Input / Output Model (CFSI I/O Model) uses an IMPLAN platform to estimate the economic impacts associated with the harvesting of fish by U.S. commercial fishermen and the other major components of the U.S. seafood industry.1 These impacts reflect how sales in each sector generate economic impacts directly in the sector in which the sale was made and then ripple throughout the state and national economy as each dollar spent generates additional sales by other firms and consumers. Economic impacts are expressed in terms of employment (full-time and part-time jobs), personal income, and output (sales by U.S. businesses). Geographically, the model estimates impacts for the U.S. as a whole and for 23 marine coastal states. For the 23 states, estimates for each sector are based on fishery products harvested in that state or imported to that state from a foreign source. Model Objective: The CFSI I/O Model was designed to estimate economic impacts for fishery products as they work their way through the entire economy from harvesting to the final users. In addition the model was designed to estimate the effect that imports have on the seafood sectors, a major part of the U.S. seafood industry.2 These imports are inputs for processors, wholesalers/distributors, and others and contribute substantially to the value added by the seafood sectors. -

Mechanical and Ecological Control of Burrowing Ghost Shrimp Summary of Final Report of the Griffin Team State of Washington Depa
Mechanical and Ecological Control of Burrowing Ghost Shrimp including Forward looking concepts for shellfish farming in Washington State Summary of Final Report of the Griffin Team Bainbridge Island, Washington October 9 2019 Ver 1.4 to State of Washington Department of Natural Resources (DNR) Contract No. 93-098786 This report is the property of DNR. Any use of text, illustrations, exhibits, ideas, concepts, and designs requires the express permission of DNR. DNR does not endorse the content in this report; content is consultation received by the Griffin Team, assembled with best available information. Copyright Washington State Department of Natural Resources 2019 Mechanical and Ecological Control of Burrowing Ghost Shrimp Ver 1.4 1 Introduction Purpose The following report proposes practical tools, farming innovation, and ecosystem action that we believe will provide non-chemical solutions for the immediate and long-term management of ghost shrimp infestations. Most importantly, we believe these recommendations provide a pathway to addressing emergent climate and water quality issues. These mechanical and biological methods could, over time, reduce shrimp populations back to manageable levels using simple, practical, inexpensive equipment, techniques, and natural biological controls. The methods we propose are promising concepts based on the best available research, experience and insights of our team, in collaboration with the knowledge and insights of a non-exhaustive list of growers who have assisted our work. These methods will require further design, testing, and investment in order to have a positive long-term effect. Our design thinking has been guided by the need to create concepts that are as close as possible to the short-term efficacy of chemical control. -
