Effective aquaculture extension service is the source of information and technologies to farmers, as well as, feedback to researchers and policymakers about the aqua farmers’ problems, needs and concerns. Information is a critical resource in the farming practice and it is the basis of extension service delivery. Effective Research-Extension-Farmer (REF) linkage ensures that farming innovations...

The Pacific whiteleg shrimp Litopenaeus vannamei (Penaeidae) is one of the most important cultivated species in world aquaculture. In Brazil, the northeastern states are home to the main shrimp producers. As shrimp aquaculture has expanded and intensified, diseases have progressively become one of the most serious threats to this industry. Infectious hypodermal and hematopoietic necrosis virus ...

Shrimp aquaculture, as well as other industries, constantly requires new techniques in order to increase production yield. Modern technologies and other sciences such as biotechnology and microbiology are important tools that could lead to a higher quality and greater quantity of products. Feeding and new practices in farming usually play an important role in aquaculture, and the addition of va...

Antimicrobials are heavily used in Chilean salmon aquaculture. We previously found significant differences in antimicrobial-resistant bacteria between sediments from an aquaculture and a non-aquaculture site. We now show that levels of antimicrobial resistance genes (ARG) are significantly higher in antimicrobial-selected marine bacteria than in unselected bacteria from these sites. While ARG i...

Aquaculture has long been seen as a sustainable solution to some of the world's growing food shortages. However, experience over the past 50 years indicates that infectious diseases caused by viruses, bacteria, and eukaryotes limit the productivity of aquaculture. In extreme cases, these types of infectious agents threaten the viability of entire aquaculture industries. This article describes t...

We present a dynamic data-driven decision support for aquaculture farm closure. In decision support, we use machine learning techniques in predicting closures of a shellfish farm. As environmental time series are used in closure, we propose two approaches using time series and machine learning for closure prediction. In one approach, we consider time series prediction and then using expert rule...

The concept of multifunctional use of marine offshore areas receives increased significance in the light of sustainable development in heavily used marine areas. Here we defined potential areas in the German EEZ for the co-utilization of offshore wind farms and offshore aquaculture applying integrated multi-trophic aquaculture (IMTA) approaches. We combined a geographic information system (GIS)...

Feed is one of the factors which play an important role in determining a successful development of an aquaculture industry. It is always critical to produce the best aquaculture diet at a minimum cost in order to trim down the operational cost and gain more profit. However, the feed mix problem becomes increasingly difficult since many issues need to be considered simultaneously. Thus, the purp...

This document addresses the potential impacts of climatic change on the aquaculture sector and to a lesser extent the contribution of aquaculture to climate change. In order to achieve these objectives, the status of this subsector in relation to the total food fish supply, recent changes therein and other related aspects are analysed with a view to addressing potential adaptations and mitigati...

the spanish turbot aquaculture sector holds a top position in the international market. thisactivity is mainly developed along the galician coast (nw spain). this article evaluates the environmentalperformance of galician turbot aquaculture according to the life cycle assessment (lca) methodology.previously, on account of the expected relevance of feed for aquaculture, marine aquafeed productio...
