Marine South East has for some time been building informal links with maritime clusters both in the UK and overseas. Offshore aquaculture uses fish cages similar to these inshore cages, except they are submerged and moved offshore into deeper water. Offshore aquaculture, also known as open ocean aquaculture, is an emerging approach to mariculture or marine farming where fish farms are moved some distance offshore. The farms are positioned in deeper and less sheltered waters, where ocean currents are stronger than they are inshore.
One of the concerns with inshore aquaculture is that discarded nutrients and feces can settle below the farm on the seafloor and damage the benthic ecosystem. According to its proponents, the wastes from aquaculture that has been moved offshore tend to be swept away from the site and diluted. Aquaculture is the most rapidly expanding food industry in the world as a result of declining wild fisheries stocks and profitable business. Major challenges for the offshore aquaculture industry involve designing and deploying cages that can withstand storms, dealing with the logistics of working many kilometers from land, and finding species that are sufficiently profitable to cover the costs of rearing fish in exposed offshore areas. To withstand the high energy offshore environment, farms must be built to be more robust than those inshore.

However, the design of the offshore technology is developing rapidly, aimed at reducing cost and maintenance. Multi-functional use of offshore waters can lead to more sustainable aquaculture “in areas that can be simultaneously used for other activities such as energy production”. Operations for finfish and shellfish are being developed. Roaming cages have been envisioned as the “next generation technology” for offshore aquaculture. These are large mobile cages powered by thrusters and able to take advantage of ocean currents. As oceans industrialise, conflicts are increasing among the users of marine space. This competition for marine space is developing in a context where natural resources can be seen as publicly owned.
Inshore marine farming systems in shallow sheltered water, as depicted here, can have problems with waste collecting on the sea floor. These problems are lessened with offshore aquaculture, where wastes are swept away from the site and diluted. The ecological impacts of offshore aquaculture are somewhat uncertain because it is still largely in the research stage. Many of the concerns over potential offshore aquaculture impacts are paralleled by similar, well established concerns over inshore aquaculture practices. One of the concerns with inshore farms is that discarded nutrients and feces can settle on the seafloor and disturb the benthos.
The “dilution of nutrients” that occurs in deeper water is a strong reason to move coastal aquaculture offshore into the open ocean. As with the inshore aquaculture of carnivorous fish, a large proportion of the feed comes from wild forage fish. Except for a few countries, offshore aquaculture has focused predominantly on high value carnivorous fish. The expense of offshore systems means it is important to avoid fish escapes. However, it is likely there will be escapes as the offshore industry expands. Compared to inshore aquaculture, disease problems currently appear to be much reduced when farming offshore.
For example, parasitic infections that occur in mussels cultured offshore are much smaller than those cultured inshore. However, new species are now being farmed offshore although little is known about their ecology and epidemiology. Spreading of pathogens between fish stocks is a major issue in disease control. Static offshore cages may help minimize direct spreading, as there may be greater distances between aquaculture production areas. However, development of roaming cage technology could bring about new issues with disease transfer and spread. Aquaculture is encouraged by many governments as a way to generate jobs and income, particularly when wild fisheries have been run down. However, this may not apply to offshore aquaculture.

Fish cages should be moved further from the coast, and more research and development of offshore cage technology must be promoted to this end. Experience from outside the aquaculture sector, e. 2013, technology associated with offshore aquaculture systems will be developed, including: “sensor systems for feeding, biomass and health monitoring, feed control, telemetry and communications cage design, materials, structural testing and modelling. By 2005, offshore aquaculture was present in 25 countries, both as experimental and commercial farms. Market demand means that the most offshore farming efforts are directed towards raising finfish. The offshore aquaculture of shellfish grown in suspended culture systems, like scallops and mussels, is gaining ground.
Suspended culture systems include methods where the shellfish are grown on a tethered rope or suspended from a floating raft in net containers. Commercial tuna ranching, offshore mussel long-lines.
