Ranaviruses can infect many vertebrate classes including fish, amphibians and reptiles, but for the most part, research has been focused on non-reptilian hosts, amphibians in particular. More recently, reports of ranaviral infections of reptiles are increasing with over 12 families of reptiles currently ...
Farmed fish are typically reared at densities much higher than those observed in the wild, but to what extent crowding results in abnormal behaviours that can impact welfare and stress coping styles is subject to debate. Neophobia (i.e. fear of the ‘new’) is thought to be adaptive under natural conditions ...
Coastal aquaculture has experienced substantial growth in the last few decades and associated impacts on natural environments are of increasing importance. Understanding both the effects of aquaculture on marine ecosystems and the processes of recovery during fallowing periods is crucial for the development ...
An arrangement and method for slicing a fish fillet. The arrangement comprises a slicing space which is isolated from its surroundings and unmanned, receiving means for receiving a cutting platform comprising a fish fillet (10) into the cutting space, said cutting platform being fillet specific so that ...
Marine dinoflagellates are a valuable source of bioactive molecules. Many species produce cytotoxic compounds and some of these compounds have also been investigated for their anticancer potential. Here, we report the first investigation of the toxic dinoflagellate Alexandrium minutum as source of water-soluble ...
The present invention is a line roller unit that includes a line roller, a bearing, a cylindrical member, and a first magnetic seal. The line roller possesses a guider on its periphery surface that guides a fishing line. The bearing is set up on the inner circumference of the line roller, with the cylindrical ...
A tracking tag (104, 200) for aquatic animals (102) may detect the occurrence of a predation event. The tag may include a pH sensitive material (210a) that degrades in the environment of an animal's gut. The degradation of the pH sensitive material causes a change in a detectable characteristic of the ...
Provided is a veterinary composition that comprises a marine algae extract with a fucoidan content of at least 5% and an Andrographis sp plant extract with an andrographolide content of at least 5%, which can be used in the control and prevention of infections in fish caused by intracellular micro-o...
An aquaponic system includes a frame (20), an aquarium (10) located at a lower portion of the frame, a plurality of cultivating tanks (30) arranged on the frame and having two opposite sides provided with inlet tanks (40) and outlet tanks (50), and a strainer unit (60) mounted on the frame. Each of ...
An aquaculture environment control system comprising a plurality of discharge conduits positioned in a vessel, the discharge conduits including one or more orifices; a fluid source in fluid communication with the plurality of discharge conduits; a gas supply source in fluid communication with at least ...
Breeding system (1) for fish belonging to the Cyprinidae family, and more particularly for zebra fish of the species Danio rerio, the said system comprising a breeding tank (2) having a bottom (2a) and side walls (2b), a spawning support (3) placed in the breeding tank (2) and comprising a platform ...
We aimed to explore the therapeutic effect of Bifidobacterium lactis on food allergy by investigating the percentage of Treg and Th17 cells in Chinese children and related molecular mechanisms. A total of 256 children with food allergy were evenly assigned into two groups: BG, the children received ...
Abstract Maternal effects often provide a mechanism for adaptive transgenerational phenotypic plasticity. The maternal phenotype can profoundly influence the potential for such environmentally induced adjustments of the offspring phenotype, causing correlations between offspring and maternal traits. ...
The kisspeptin/GPR54 system plays a crucial role in the regulation of the reproductive axis in vertebrates. Male pregnancy and ovoviviparity are special reproductive phenomena among vertebrates. To better understand the neuroendocrine mechanisms of male pregnancy, cDNAs encoding kiss2 and GPR54 were ...
Riparian and aquatic habitats support biodiversity and key environmental processes in semi-arid and arid landscapes, but stressors such as conventional livestock grazing, wildfire, and drought can degrade their condition. To enhance habitat for fish and wildlife and increase resiliency in these critical ...
Here we describe GoFish, a strategy for single-species environmental DNA (eDNA) presence/absence assays using nested PCR. The assays amplify a mitochondrial 12S rDNA segment with vertebrate metabarcoding primers, followed by nested PCR with M13-tailed, species-specific primers. Sanger sequencing confirms ...
Background Different diets during pregnancy might have an impact on the health, reflected in the birthweight of newborns. The consumption of fruits and vegetables during pregnancy and the relationship with newborn health status have been studied by several authors. However, these studies have shown ...
Abstract Ranging behaviour and temporal patterns of individuals are known to be fundamental sources of variation in social networks. Spatiotemporal dynamics can both provide and inhibit opportunities for individuals to associate, and should therefore be considered in social analysis. This study investigated ...
Interviews were conducted with a small group of Malawians over the age of 60 in rural Karonga district and in Area 25 of the capital, Lilongwe. We asked their views on the changes in diet that had taken place over their lifetimes and also on the causes of 'noncommunicable' diseases, such as Type 2 diabetes ...
Abstract Atlantic herring (Clupea harengus), a vital ecosystem component and target of the largest Northwest Atlantic pelagic fishery, undergo seasonal spawning migrations that result in elusive sympatric population structure. Herring spawn mostly in fall or spring, and genomic differentiation was ...
