With the intensification of aquaculture to meet the rising demands of fish and shellfish, disease outbreaks during the larval and adult stages are a major challenge faced by aqua culturists. As the prophylactic use of vaccines and antibiotics has several limitations, research is now focused on sustainable alternatives to vaccines and antibiotics, e.g., medicinal plants, probiotics, postbiotics, ...

Quality parameters and storage stability were evaluated through biochemical, textural, and microbial analyses of the Norwegian red sea cucumber Parastichopus tremulus at two different storage temperatures (0 °C and 4 °C) over 17 days. During storage, the pH decreased from 7 to 6.3, the texture became softer decreasing from 47.3 to 0.3 N, while K-value increased from 4 to 52 %, microbial counts ...

Environmental DNA (eDNA) detection employing quantitative PCR (qPCR) and droplet digital PCR (ddPCR) offers a non-invasive and efficient approach for monitoring aquatic organisms. Accurate and sensitive quantification of eDNA is crucial for tracking rare and invasive species and understanding the biodiversity abundance and distribution of aquatic organisms. This study compares the sensitivity and ...

This report summarizes the findings from a price experiment survey on the willingness to pay (WTP) for salmon produced using new production systems in salmon farming in three countries (Norway, Canada and Scotland). This includes land-based, floating closed containment cages and offshore production systems. The results revealed that consumers preferred salmon produced using conventional (traditional) ...

Rural public policies are important and contested in many countries. Politicians and administrations often have high ambitions for both spatial policies (e.g. maintaining demography, local work, businesses etc.) technological development (modernisation, increased productivity etc.), while production tend to be limited by markets (as in the case of agricultural productions) or resources (as in e.g. ...

This study investigated how farmed blue mussels (Mytilus edulis) can optimize human nutrient intake. A particular focus was on assessing nutrient preservation during steaming and freeze-drying, processes that could deplete nutrients. The study compared the content of essential amino acids and fatty acids in steamed and freeze-dried blue mussels to the nutritional needs of humans and farmed Atlantic ...

The main objective of the SeaMark project is to demonstrate how to scale up innovative seaweed cultivation and processing into price-competitive product applications making the entire supply chain attractive for commercial investments. This report is the third outcome from SeaMark Work Package 7 (WP7) – Go-To-Market (GTM) strategies for products, and it builds a foundation for the contribution ...

As recurrent disease outbreaks impart economic adversity across the global shrimp farming sector in general, and in Asia in particular, clarifying determinants of outbreak susceptibility carries significance for sustainability in economic growth and social and environmental prospects. This study employs logistic regression to assess the probability of disease occurrence in intensive white leg shrimp ...

A detailed description of lumpfish reproductive biology has been described in terms of gonadal development using histological analysis and physiology using sex steroid development. This knowledge of basic reproductive biology of lumpfish has adopted by our industry partners in their breeding activities in their facilities. Our results demonstrated that spawning of lumpfish can be shifted using ...

A considerable number of antibacterial agents are derived from bacterial metabolites. Similarly, numerous known compounds that impede bacterial virulence stem from bacterial metabolites. Enteropathogenic Escherichia coli (EPEC) is a notable human pathogen causing intestinal infections, particularly affecting infant mortality in developing regions. These infections are characterized by microvilli ...
