neomar GmbH

Development and construction of aquaculture water treatment units for marine land-based recirculating aquaculture systems worldwide. In the last few decades aquaculture developed into an alternative to cover the increasing human demand for fish. In the last decades marine aquaculture (mariculture) has grown at an average of 9% per year. Considering the rising demand for fish and the over-exploitation of global fish stocks, a further growth of mariculture is not in doubt. However, the growth of conventional mariculture systems along the coasts will be limited and the future demand can be only satisfied by new concepts and technologies. For the first time the oceanloop, developed by neomar, allows the inland production of seafish without access to natural seawater. It is an alternative to conventional fish farming in open water aquaculture systems. The specially produced seawater is continuously circulated and recycled. The water loss and the impact on the environment are minimal.

In terms of consumer protection and freshness the oceanloop technology will set new benchmarks. The fish is only taken from the production on demand, professionally anesthetized and cooled down in less than an hour to a temperature around 0°. Packed in ice, the fish reaches the customer with one-of-a-kind freshness. In doing so, the market value, the product safety and the shelf life at the customer is increased considerably.

 

Also the induced enrichment of toxins, such as saxi- and ciguatoxins, in marine organisms within food chains, which is developing into a growing problem in many parts of the world, can be safely eliminated. Similarly, the assimilation of environmental poisons, such as heavy metals or dioxins, which lead to problems in natural fish production, as well as open aquaculture systems, can be safely eliminated by the traceability of all operating supplies.

The oceanloop technology stands for an efficient use of natural resources, such as water, electrical and thermal energy and food.

neomar is currently the only company worldwide, which offers the inland production of seafish without access to natural seawater. The oceanloop does not require any seawater to dilute or discharge waste, as it is completely removed by the water treatment.

The oceanloop works, in contrast to many other recirculating aquaculture systems, with almost the same water level and without piping in the components of primary water circulation. By this, pressure losses are minimized in such a way, that energy-efficient flow pumps can be used. Furthermore, a sophisticated component design leads to synergies between the different units of water treatment and improves the overall filter efficiency of the system.

In terms of climate management, forms and amount of energy used in the farm have to be optimized, concerning ecological and economical factors. This has to be done in close cooperation with the customer, because investment strategy as well as site-related factors must be considered.

In particular, the use of renewable energy (such as geothermal or solar heat) and/or waste heat are in the focus of development. Biogas plants, steelworks and landfills can be named as examples here. For the first time, the unique feature of farming seafish wherever you are, enables a successful implementation of these concepts also for marine aquaculture.

In comparison to terrestrial animal husbandry, fish stands out for a very good feed conversion. This underlines the future potential and sustainability of aquaculture.

Furthermore, feed conversion in theoceanloop is as a rule better than in open aquaculture systems, as the environmental conditions can be well controlled.

The concept of flexible basin segmentation by moveable net walls enables modification of the aspired market size at short notice as well as a change to new species. Basin separations can be added, removed or changed in size easily. This is a significant advantage to use market niches or to react on the needs of the customers. Similarly, it is possible to switch a production module to a new target species.

Furthermore, the water treatment technology enables the highest water quality. From a technological point of view, there are almost no limits regarding the biological requirements of different fish species. This corporate flexibility leads to a competitive aquaculture production.
