Fisheries are complex adaptive social-ecological systems (SES) that consist of interlinked human and ecosystems. They have mainly been studied by the natural sciences and focused on the ecosystem. However, rising concerns about sustainability and increasing complexity of societal challenges often require an understanding of fisheries in a SES context. For this purpose, the study of the human ...

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 ...

<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 ...

This themed issue of papers for Maritime Studies emerges out of a special session of the MARE 2015 conference held in Amsterdam. The aim of this Introduction is to provide a brief background to poststructural scholarship drawing on examples and cases from research on fisheries. We argue that a poststructural sensibility has made an important impact on scholars interested in fisheries issues even ...

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 ...

Shortening codend lastridge ropes can be an effective fishing gear modification to improve the size selection properties in diamond mesh codends. Lastridge ropes attached to codend selvedges withstand the longitudinal forces created by the catch building up and therefore, prevent the codend meshes from closing. However, the extent to which the lastridge ropes should be shortened to maximize the ...

This study reports the isolation of two novel cysteine-rich antibacterial peptides, turgencin A and turgencin B, along with their oxidized derivatives, from the Arctic marine colonial ascidian <i>Synoicum turgens</i>. The peptides are post-translationally modified, containing six cysteines with an unusual disulfide connectivity of Cys<sup>1</i>-Cys⁶, Cys²-Cys⁵, and ...
