The use of food grade wild-captured species as bait for other fisheries questions the sustainability of food production. In pot fisheries, bait is an important factor determining the effectiveness of the gear. In snow crab (Chionoecetes opilio) fishery, the pots are normally baited with squid (Illex sp.) and herring (Clupea harengus). This fishery uses substantial amounts of bait for each ...

Interferon-induced proteins with tetratricopeptide repeats (IFITs) are involved in antiviral defense. Members of this protein family contain distinctive multiple structural motifs comprising tetratricopeptides that are tandemly arrayed or dispersed along the polypeptide. IFIT-encoding genes are upregulated by type I interferons (IFNs) and other stimuli. IFIT proteins inhibit virus replication by ...

Infectious salmon anemia virus (ISAV) is a piscine orthomyxovirus, which causes multisystemic disease in farmed Atlantic salmon that may result in large losses. Previous work has suggested that ISAV is able to resist the antiviral state induced in cells by type I interferon (IFN). These studies were, however, mainly based on cytopathic effect (CPE) reduction assays. Here we have investigated the ...

Environmental DNA (eDNA) has rapidly emerged as a promising biodiversity monitoring technique, proving to be a sensitive and cost‐effective method for species detection. Despite the increasing popularity of eDNA, several questions regarding its limitations remain to be addressed. We investigated the effect of sampling medium and time, and preservation methods, on fish detection performance based on ...

Background: Largemouth bronze gudgeon (Coreius guichenoti) is of economic importance in China, distributed in upstream regions of the Yangtze River in China. But it has recently dramatically declined and is close to elimination. However, there is little knowing about the character of its intestinal microbiota. This study was conducted to elucidate the intestinal microbiota of wild largemouth bronze ...

It is well-known that operating within the boundaries of a national park provides commercial actors with the opportunity to charge a price premium, though this has to a lesser degree been demonstrated for marine protected areas. We estimate national tourists' willingness-to-pay a price premium for boat trips in the Nha Trang Bay Marine Protected Are, Vietnam, using a discrete choice experiment. Our ...

Research on the innate immunity has accelerated over the last decades. The main reason for this has been the discovery of receptors recognizing danger molecules from pathogens. This has been facilitated through genome and transcriptome sequencing of different fish species. Also, endogenous host molecules from sterile physiological insults may also bind to certain receptors and induce immunological ...

Rising atmospheric carbon concentrations affect global health, the economy, and overall quality of life. We are fast approaching climate tipping points that must be addressed, not only by reducing emissions but also through new innovation and action toward carbon capture for sequestration and utilization (CCSU). In this perspective, we delineate next-generation biotechnologies for CCSU supported by ...

The relationship between annual growth in the catches of fishing nations and the quality of the institutions of those nations is analyzed. Catch volumes are used as a proxy for development, since economic performance indicators based on a common set of definitions do not exist. 49 major fishing nations were selected for this study, including 22 OECD countries and several developing countries. Three ...

In the “Future We Want,” states and non-state actors are invited to contribute to achieving sustainable development goals through various means and mechanisms. This includes securing justice for the most marginalized and disadvantaged sectors like small-scale fisheries, whose rights and access to resources are threatened by Blue Economy/Growth initiatives. While strong and just institutions are ...
