NeXOS, developing and evaluating a new generation of in-situ ocean observation systems

Many changes are occurring in the physical, chemistry and biology processes of the ocean. Understanding how these changes are driven is an element of the key environmental descriptors identified by the European Marine Strategy Framework Directive (MSFD) with the ultimate goal being to protect the resource ...

Quaternion based control for robotic observation of marine diversity

Marine biodiversity is increasingly affected by human activities such as climate change, habitat destruction and fishing. In this context a key challenge for marine biologists is to be able to monitor biodiversity at large scale and high temporal frequency. However, underwater observations of marine ...

Sustainable management of oil polluting wrecks and chemical munitions dump sites

Dumped chemical weapons that are corroding and exposed to the marine environment can cause contamination and health risks for marine fauna and humans. This paper describes some of the work that is done in the EU-DAIMON (Decision Aid for Marine Munitions) project including the development of a decision ...

Validation and demonstration of novel oceanographic sensors on selected measurement platforms in the NeXOS project

This article describes the initial planning and outcomes of validation and demonstration efforts for oceanographic sensors in the EU-funded project NeXOS. The project has developed novel, multi-functional optical and acoustic sensors for environmental monitoring and mapping. These sensors are subject ...

Real-time fish detection in trawl nets

This work presents advances towards the development of the Deep Vision system, consisting of a stereo camera setup attached to a trawl, which will make it possible to identify and measure the fish passing through without bringing them aboard the boat. This identification and measuring task requires ...

A solar-powered fish pond management system for fish farmng conservation

Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be ...

OceanRoads: Fishing area separation and relation discovery through VMS trace analysis

Vessel Monitoring Systems (VMS) provide trajectory data of fishing vessels to discover the spatial-temporal pattern of fishing activities. Although previous researches exhibit the fishing resource distribution in space and time, the information on vessel sailing activities traveling from one fishing ...

The use of Local Ecological Knowledge as a complementary approach to understand the temporal and spatial patterns of fishery resources distribution

Background Acquiring fast and accurate information on ecological patterns of fishery resources is a basic first step for their management. However, some countries may lack the technical and/or the financial means to undergo traditional scientific samplings to get such information; therefore affordable ...

Using vessel-based drones to aid commercial fishing operations

Fishing operations can realize significant benefits from airborne image data. Current large-scale tuna fishing vessels employ manned helicopters to find fish quickly and reduce fuel usage. 90% of the world's tuna catch is taken in by the 2% of the world's fishing fleet, using helicopters. However, helicopters ...

URSI France 2017 workshop on radio science for humanity: Journees scientifiques URSI-France 2017 radiosciences au service de l'humanité (part 2): Copernicus, a major European ...

The Copernicus program (previously known as GMES: Global Monitoring for Environment and Security) is a major European undertaking for the continuous monitoring the Earth system. Copernicus is one of the two pillars — together with the Galileo program — of the cooperation between the European Union (EU), ...

Recreational freshwater fishing drives non-native aquatic species richness patterns at a continental scale

Aim Mapping the geographic distribution of non-native aquatic species is a critically important precursor to understanding the anthropogenic and environmental factors that drive freshwater biological invasions. Such efforts are often limited to local scales and/or to single species, due to the challenges ...

CamOptimus: a tool for exploiting complex adaptive evolution to optimize experiments and processes in biotechnology

Multiple interacting factors affect the performance of engineered biological systems in synthetic biology projects. The complexity of these biological systems means that experimental design should often be treated as a multiparametric optimization problem. However, the available methodologies are either ...

Why regulatory indifference towards pharmaceutical pollution of the environment could be a missed opportunity in public health protection. a holistic view

The last generation has witnessed bludgeoning of the world's population, a spike in disease burden, and unprecedented levels of pharmaceutical consumption and production. Unfortunately, pharmaceuticals have left their industrial and household confines and leaked into the environment. Pharmaceuticals ...

The Rising Tide of Antimicrobial Resistance in Aquaculture: Sources, Sinks and Solutions

As the human population increases there is an increasing reliance on aquaculture to supply a safe, reliable, and economic supply of food. Although food production is essential for a healthy population, an increasing threat to global human health is antimicrobial resistance. Extensive antibiotic resistant ...

Release and Constancy of an Antibiotic Resistance Gene in Seawater under Grazing Stress by Ciliates and Heterotrophic Nanoflagellates

Extracellular DNA (exDNA) is released from bacterial cells through various processes. The antibiotic resistance genes (ARGs) coded on exDNA may be horizontally transferred among bacterial communities by natural transformation. We quantitated the released/leaked tetracycline resistance gene, tet(M) over ...

Nutritional value of a partially defatted and a highly defatted black soldier fly larvae (Hermetia illucens L.) meal for broiler chickens: apparent nutrient digestibility, ...

Background The study aimed to determine the apparent total tract digestibility coefficients (ATTDC) of nutrients, the apparent metabolizable energy (AME and AMEn) and the amino acid (AA) apparent ileal digestibility coefficients (AIDC) of a partially defatted (BSFp) and a highly defatted (BSFh) black ...

Cathelicidin-trypsin inhibitor loop conjugate represents a promising antibiotic candidate with protease stability

Cathelicidins are regarded as promising antibiotics due to their capability against antibiotic-resistant bacteria without cytotoxicity. However, some concerns about the balance of cytotoxicity and antimicrobial activity, weak stability and enzymatic susceptibility sually restrict their therapeutic use. ...

Complete genome sequence of Vibrio campbellii strain 20130629003S01 isolated from shrimp with acute hepatopancreatic necrosis disease

Background Vibrio campbellii is widely distributed in the marine environment and is an important pathogen of aquatic organisms such as shrimp, fish, and mollusks. An isolate of V. campbellii carrying the pirABvp gene, causing acute hepatopancreatic necrosis disease (AHPND), has been reported. There ...

Phylogeny and expression analysis of C-reactive protein (CRP) and serum amyloid-P (SAP) like genes reveal two distinct groups in fish

The acute phase response (APR) is an early innate immune function that is initiated by inflammatory signals, leading to the release of acute phase proteins to the bloodstream to re-establish homeostasis following microbial infection. In this study we analysed the Atlantic salmon (Salmo salar) whole-genome ...

The water use of Indian diets and socio-demographic factors related to dietary blue water footprint

Agriculture accounts for ~ 90% of India's fresh water use, and there are concerns that future food production will be threatened by insufficient water supply of adequate quality. This study aimed to quantify the water required in the production of diets in India using the water footprint (WF) assessment ...
