Abstract In the California Current Ecosystem, krill represent a key link between primary production and higher trophic level species owing to their central position in the food web and tendency to form dense aggregations. However, the strongly advective circulation associated with coastal upwelling ...
The agroindustry generates a large amount of waste. In postharvest, food losses can reach up to 50%. This waste represents a source of contamination of soil, air, and bodies of water. This represents a problem for the environment as well as for public health. However, this waste is an important source ...
Aquaculture fish production is experiencing an increasing trend worldwide and determines environmental concerns mainly related to the emission of pollutants. The present work is focused on the improvement of the sustainability of this sector by assessing the anaerobic digestion (AD) of slurry. Wastewater ...
Abstract The origin of species is a central topic in biology. Ecological speciation might be a driver in adaptive radiation, providing a framework for understanding mechanisms, level, and rate of diversification. The Arctic charr Salvelinus alpinus L. is a polymorphic species with huge morphological ...
The consumption of seafood and the use of fish oil for the production of nutraceuticals and fish feed have increased over the past decades due the high content of long-chain polyunsaturated omega-3 fatty acids. This increase has put pressure on the sustainability of fisheries. One way to overcome the ...
The population growth of top predators depends largely on environmental conditions suitable for aggregating sufficient and high-quality prey. We reconstructed numerically the size of a resident population of California sea lions in the Gulf of California during 1978–2019 and its relation with multi-decadal ...
Bioorthogonal chemistry introduces affinity-labels into biomolecules with minimal disruption to the original system and is widely applicable in a range of contexts. In proteomics, immobilized metal affinity chromatography (IMAC) enables enrichment of phosphopeptides with extreme sensitivity and selectivity. ...
Vibrio parahaemolyticus is the leading cause of seafood-borne bacterial poisoning in China and is a threat to human health worldwide. The aim of this study was to assess the antibiotic resistance profiles and distribution of heavy metal resistance of V. parahaemolyticus isolates from Penaeus vannamei ...
In fish-farming areas, copious amounts of organic matter are released into the surrounding environment. Although it is well-known that bacterial community structures and activities are tightly coupled with organic conditions in the environment, actively growing bacteria (AGB) species that are responsible ...
Marine biofouling can cause a biocorrosion, resulting in degradation and failure of materials and structures. In order to prevent sea creatures from attaching to the surface, in this work, a new environmentally friendly antifouling coating by incorporating antibacterial polymers and natural antifouling ...
Salmonid alphavirus infection results in pancreas disease causing severe economic losses for Atlantic salmon aquaculture. Knowledge about genes and pathways contributing to resistance is limited. A 54 K SNP panel was used to genotype 10 full-sibling families each consisting of ~ 110 offspring challenged ...
Management performance of five alternative stock assessment methods was evaluated by using them to set harvest levels targeting multi-species maximum yield in a multi-species flatfish fishery, including single-species and hierarchical multi-species models, and methods that pooled data across species ...
Le invasioni biologiche sono la conseguenza globale di un mondo sempre più connesso e della crescita della popolazione umana. ll numero di specie esotiche invasive e il sottoinsieme di specie esotiche che si diffondono ampiamente in aree nelle quali non sono autoctone sono in aumento e influiscono sull'ambiente ...
A travel case includes a case body defining an interior cavity in which to carry articles and an exterior shell; an inflatable floatation aid fixed to the exterior shell; an inflator in communication with the inflatable floatation aid, for inflation of the inflatable floatation aid; and a locator beacon ...
Apparatus and method for maneuvering marine vessel is disclosed. The apparatus is configured to: receive (202) a location command defining a future geographic location; receive (204) an orientation command defining an orientation in the future geographic location; and generate (226) required control ...
The invention relates to a protective glove (1) for shielding penetrating radiation, having a radiation-inhibiting layer (2) which at least partially surrounds the protective glove (1) and is situated directly on the protective glove (1) or is incorporated into the protective glove (1), characterised ...
A method of controlling propulsion of a marine vessel (10) includes receiving proximity measurements (90) from one or more proximity sensors (72,74,76,78) on the marine vessel (10) and limiting user input authority over propulsion output in a direction of an object (O) by at least one propulsion device ...
The invention relates to a Man Over Board (MOB) detection system that can be integrated in a vessel (101A), in the vessel's instrument room (101B) near the vessel's bridge (101C) that allow detecting humans going overboard. In an embodiment, the invention provides an apparatus or system forming a Man ...
A lifeboat hook assembly comprising a hook-shaped beak (5) and a release mechanism (6), said hook shaped beak (5) is rigidly connected to a lifeboat (2) at one end, said hook shaped beak (5) having a downwardly oriented shoulder (18) against which a loop (17) is adapted to rest so that the lifeboat ...
