FLAVOuR

Sustainable Aquaculture of Flatfish from Asia and a Novel Voluntary Grading Device for Our Region - FLAVOuR

Objective
The overall objective of the FLAVOuR project is to obtain new species for aquaculture in Germany. The project will analyze the market for two high-priced Asian flatfish species, Starry flounder (Platichthys stellatus) and the Japanese flounder (Paralichthys olivaceus). The efficiency of a land-based aquaculture facility for these species in Bremerhaven region will be determined and a novel device for voluntary size grading for these fish species will be developed and tested.


 

Background information and content of the project

The importance of the aquaculture industry has grown constantly in recent years and this trend will continue. In contrast, catches from the industrial fishery cannot be further increased due to the alarming trends observed among natural fishery stocks. The finfish aquaculture sector in Germany is traditionally based on freshwater, with only a few commercially relevant species. Saltwater species can only be cultured in land-based systems because the short German coastline is subject to a number of stakeholder conflicts. In such land-based recirculation aquaculture systems (RAS) currently only high-priced, fast-growing fish species can be produced profitably. In comparison to open systems RAS offers some advantages such as the sustainable production of fresh maritime food, the culture of exotic species without the risk of introducing invasive species into local waters, the absolute control of the nursery parameters and the shortening of transport routes, as these systems can operate independently from the sea.

Two high-priced flatfish species popular in Asia were selected for investigation into extending the range of high quality fresh fish in Germany. The Starry flounder, is an attractive fish with a banded fin fringe, and the Japanese flounder, a very popular sashimi fish. Currently both species can only be obtained as frozen goods on the German market. The original habitat of the species is the Pacific. Both species are already established in Asian aquaculture and the Japanese Flounder in particular is already well studied. Both species have wide tolerance of temperature and salinity. Both species are yet to bet established in European aquaculture.

Our commercial project partner NORDSEE will conduct a market analysis for both flatfish species, the interest of potential customers will be tested, new types of preparation and products will be developed and the commercial success of these products will be estimated. The ttz institute Bremerhaven will investigate bio-economics, determine production costs and assess the economic viability of RAS for both species for successful culture in the Bremerhaven region.

imare together with the partners IKZ and Engel Netze will develop and test a “voluntary size grading device”. The background of this research need is explained by the fact that frequent grading is necessary for most aquaculture species. It ensures even growth and a better distribution of resources by preventing food dominance of single individuals. This grading has two major negative effects. On one hand the farmer has higher expenses (personnel, infrastructure, energy), and on the other hand it is stressful for the animals (handling, injury, infection) accompanied by reduced growth and increased disease susceptibility. To examine and improve the success of the self-grading process, scientists of the imare will investigate how the fish will adapt to different grading devices at the research facility “Center for aquaculture Research” (ZAF).

Beside the development of the Self-grading device, imare will take the coordination of the project as well as the supply, the keeping and the inspection of the fishes.

 

Funding

This project is funded by the Innovation program 2020 of the bis, under the section "Fisheries and Aquaculture". The aim of this program is to support companies involved in the fish industry of Bremerhaven, by transferring application oriented knowledge from science to economy. FLAVOuR is a collaborative project of partners from research and industry, with 50:50 participation. The funding is ensured by the Land Bremen.

 

Duration

Expected completion of the project FLAVOuR is May 2015.
