Vision is very important to fish as it is required for foraging food, fighting competitors, fleeing from predators, and finding potential mates. Vertebrates express opsin genes in photoreceptor cells to receive visual signals, and the variety of light levels in aquatic habits has driven fish to evolve ...
There is a rising imperative to increase the operational availability of maritime vessels by extending the time between full docking cycles. To achieve operational efficacy, maritime vessels must remain clear of biological growth. Such growth can cause significant increases in frictional drag, thereby ...
Background Little is known regarding risk factors for lymphatic filariasis (LF) in Central Africa. To expand on what is known, we studied the epidemiology of LF in two endemic villages in the Democratic Republic of the Congo. Methods Dependent variables were Wuchereria bancrofti antigenaemia detected ...
Early warning signals (EWSs) offer the hope that patterns observed in data can predict the future states of ecological systems. While a large body of research identifies such signals prior to the collapse of populations, the prediction that such signals should also be present before a system’s recovery ...
Background Several studies have reported the strong resistance of Anopheles gambiae s.l. complex species to pyrethroids. The voltage-dependent sodium channel (Vgsc) gene is the main target of pyrethroids and DDT. In Benin, the frequency of the resistant allele (L1014F) of this gene varies along the ...
The concept of multi-use of the sea has gained popularity in recent years as a result of ocean space (coastal areas and regions with relatively small sea space in particular) becoming increasingly crowded due to the development of the maritime economy. Competing claims for space can be a source of conflict, ...
Differences in health outcomes between meat-eaters and non-meat-eaters might relate to differences in dietary intakes between these diet groups. We assessed intakes of major protein-source foods and other food groups in six groups of meat-eaters and non-meat-eaters participating in the European Prospective ...
Although Turner syndrome is most commonly associated with a 45,X genotype, other mosaic genotypes are present in approximately half of all cases. We describe a case of Turner syndrome with a 46,XY genotype by conventional 5-cell karyotype who was subsequently found to have a mosaic genotype of 18% 45,X ...
Elongation of very long chain fatty acids protein 6 (Elovl6) is a key enzyme in fatty acid synthesis, which participates in converting palmitate (C16:0) to stearate (C18:0). Although studies of Elovl6 have been carried out in mammals, the nutritional regulation of elovl6 in fish remains poorly understood. ...
Background Reverse transcription quantitative PCR (RT-qPCR) is widely used for gene expression analysis in various organisms. Its accuracy largely relies on the stability of reference genes, making reference gene selection a vital step in RT-qPCR experiments. However, previous studies in mollusks only ...
ABSTRACT A rare nontailed virus designated NO16 was isolated against Vibrio anguillarum, a major aquaculture pathogen for both fish and shellfish. Here, we announce the 10,594-bp genome sequence of Vibrio phage NO16 with a 23-gene content.
The cephalopod fauna of the southwestern Atlantic is especially poorly-known because sampling is mostly limited to commercial net-fishing operations that are relatively inefficient at obtaining cephalopods associated with complex benthic substrates. Cephalopods have been identified in the diets of many ...
Background Local adaptation of marine and diadromous species is thought to be a product of larval dispersal, settlement mortality, and differential reproductive success, particularly in heterogeneous post-settlement habitats. We evaluated this premise with an oceanographic passive larval dispersal ...
A finger glove liner (2) comprising at least one finger portion (1), for arrangement inside an outer finger glove, making up a grip strengthening finger glove (3) is provided. The finger glove liner (2) is made of a stretchable material (4) in order to suit more than one size of hands, wherein at least ...
An underwater communications system includes a network communication interface, one or more computer processors, and a memory containing computer program code that, when executed by operation of the one or more computer processors, performs an operation. The operation includes storing a plurality of ...
A glove is provided that is superior in impact resistance and allows prevention of dislocation and detachment of an impact-resistant pad. The glove includes: a stretchable glove main body made of fiber; a coating layer comprising a synthetic resin or rubber as a principal component, being laminated ...
The present invention provides a device useful for transporting and/or handling equipment in an underwater environment for performing work, the device comprising at least the following components: a floating hydraulic unit (1) comprising a first enclosure (1a), preferably with a cylindrical wall, containing ...
A sealing arrangement is used when mounting a thruster in a well box attached to a hull of a marine vessel. The well box has an axis, a bottom flange, a top flange, an annular wall therebetween and hoisting pipes fastened parallel with the axis to the bottom flange radially outside the annular wall. ...
Marine environment monitoring has attracted more and more attention due to the growing concern about climate change. During the past couple of decades, advanced information and communication technologies have been applied to the development of various marine environment monitoring systems. Among others, ...
The invention is an offshore aquaculture facility based on the modification of a bulk cargo ship. It is achieved by converting a bulk cargo ship into a floating offshore facility at sea, with a number of cultivation tanks located below the deck, a movable hoisting system on the deck, a water-changing ...
