The European production of marine macroalgae is mainly based on harvest of natural resources. Catches are stable, and an increase in production might depend on cultivation of seaweed, to prevent high pressure on natural resources. Cultivation of seaweed is less developed in Europe than in Asia, where it has long traditions. The NETALGAE project aims to assess the existing production of macroalgae, and to transfer knowledge across European regions to promote sustainable development within the European macroalgae industry. NETALGAE aims to create a European network of relevant stakeholders within the marine macroalgae sector, by creation of business tools such as database, website, trade directory and training materials. The network will include primary producers, processors, technology suppliers, process consultants, research institutes, development agencies, local governments and relevant community groups and other stakeholders. A wide ranging policy study will establish a best practice model and suggest policies for the successful and sustainable commercial utilization of marine macroalgae resources. The project runs from 2010-2012, and is financed by the Atlantic Area Transnational Programme, The European Regional Development Fund and by national co- funding. The oral presentation will describe the NETALGAE project, its aims, objectives, partners and the preliminary results from the Norwegian partner.

Biological control of sea lice with wrasse is considered an alternative to medicines and can form part of an integrated sea lice management plan. The use of wrasse can also have benefits in organic fish production where there is a limitation on the use of medicines. While wrasse have been used previously in sea lice control there have been reservations about fishing the wrasse from wild stocks with possible erosion of local stocks and changes in population structure. There have also been concerns regarding potential diseases that might be transferred to the farmed setting by using wild fish. An EU Northern Periphery Project entitled "Ecofish" has been established to examine the rearing of ballan wrasse Labrus bergylta and the application of this species in sea lice control. While other species of wrasse such as corkwing and goldsinny have been reared previously, there has been no report of rearing success with ballan wrasse. This species has been shown to be a successful cleaner of sea lice in preliminary trials and may be more suitable than smaller wrasse with larger second production year salmon. This poster will present the aims of the organic fish project to establish broodstock populations of ballan wrasse, to develop rearing techniques for ballan wrasse in the hatchery phase, to examine the ongrowing of wrasse, to establish good husbandry of wrasse in salmon and cod cages, and to evaluate how effective ballan wrasse are in cleaning lice from both salmon and cod stocks.

Husdyrgjødsel er ein viktig ressurs på mange gardsbruk. Etter år med høge handelsgjødselprisar har den relative verdien av husdyrgjødsel auka. Dette gjer til at det er god økonomi i å unytte husdyrgjødselen best mogeleg. Til eng er spreiing av husdyrgjødsel om våren det som gjev best verknad. Då oppnår ein også bra etterverknad i gjenveksten. Hausten er dårlegaste tida for spreiing av blautgjødsel og gylle på eng. I denne artikkelen vil me sjå på kva lovverk som gjeld for spreiing av husdyrgjødsel og korleis ein kan få best mogeleg verknad av den.

Use of organic fertilizers in fish pond has been common since ancient times. Applying fertilizers stimulates the growth of phytoplankton, primary producers of the fish food chain. Artificial nitrogen and phosphorus fertilizers are nowadays the main types of nutrients supply in ponds. However, the use of mineral fertilizers is not sustainable due to the use of nonrenewable resource and the impact on the environment. Moreover, the Norwegian government has defined the national ambition that organic food production and food consumption should be more than 15% by 2020. Modern societies produce large amount of organic wastes, which could be reused. Ahead of utilizing such waste as fertilizers in aquaculture, the first step is to gain knowledge about the mineralization patterns in seawater. This knowledge is important to ensure proper supply time and proper amount of nutrients from waste for optimal production with minimal negative impact on the environment This poster will present a study about nitrogen mineralization pattern from organic materials relevant as fertilizers in sustainable aquaculture.
