Growing demands stimulate the intensification of production and create the need for practices that are both economically viable and environmentally sustainable. As European Union banned the use of antibiotics in production in 2003, several alternative treatments have been suggested, including probiotics. The first probiotic study in aquaculture was published in 1986, and since then probiotics ...

Interkommunalt samarbeid i sjø er relativt nytt i forhold til interkommunalt samarbeid på andre områder. Det er likevel klart at mange kommuner, særlig små distriktskommuner mangler eller har liten plankompetanse og derfor kan ha stor nytte av samarbeid på plansiden. En utfordring med interkommunal planlegging er imidlertid spørsmålet om kommunal styring. For politisk ledelse i kommunen vil det ofte ...

Stortinget skal snart behandle forslaget om at internasjonale studenter må betale høye studieavgifter. Om avgiftene innføres fra høsten, vil det etter alt å dømme bety færre internasjonale studenter, nedlegging av studieprogrammer, mindre mangfold og at vi mister kompetanse både i Norge og land i sør. Det med mindre vi nå tenker nytt og innovativt om finansiering.

<p>Introduction. This is an article on whether Crimea’s declaration of independence is illegal or not. Is it contradictory to international law? My working hypothesis is that “people’s” right to selfdetermination and selfgovernment are part of its “residual rights”. Referendum confirms the authenticity of the popular will; declaring independence. The main topic is whether remedial secession is ...

Bottom trawlers are engaged in multi-species fisheries and fish for profit. In quota-regulated fisheries, intra- and inter-temporal substitutions of fishing effort is regarded as a key mechanisms that influences the profitability of the fishing portfolio. The feeding and spawning migration patterns of the available fish species in the fishing portfolio alter the bio-economic conditions of the different ...

The expansion of the aquaculture sector around the world has resulted in a growth of the demand for fishmeal (FM). Due to the limited sea resources, the price of FM has risen significantly in past years pushing the sector to find substitutes. In this context, insects attract more and more industrial and scientific attention as they have many advantages. First, with around one million species estimated, ...

Small-scale fisheries are complex, diverse and dynamic. Therefore, to understand these fisheries, governance is favoured to management as a more comprehensive analytical framework that aims to catch issues and challenged beyond the technical aspects of management. Following a phronesis approach, embedding theory into reality, I chose the case study of the small-scale fisheries of the San Andrés ...

Infectious pancreatic necrosis virus (IPNV) is an aquatic member of the Birnaviridae family that causes widespread disease in salmonids. IPNV is represented by multiple strains with markedly different virulence. Comparison of isolates reveals hyper variable regions (HVR), which are presumably associated with pathogenicity. However little is known about the rates and modes of sequence divergence and ...

Are there limits to the governability of a fishery? The establishment of a 200 nautical mile economic zone in Norway in 1977 made it possible to change from an open-access regime to a more closed one. In this process, the former self-regulating Norwegian fishing industry, to a large extent, accepted and adapted an explicit, hierarchical form of state-run governance. However, the process of change ...

This study investigates intended visitation behavior of tourists toward Rekawa wetland under anticipated climate change (CC) scenarios. An interview-based contingent visitation survey was conducted with 365 foreign and domestic tourists to estimate the effects of CC on future visitation. Based on two IPCC scenarios using two direct and three indirect climatic factors, we composed a CC environmental ...
