Fishing system for fishing for shrimps, fish processing line and vessel provided therewith, and method therefor

Underwater electrical power plant, a system and a method

An underwater power plant, a method and a system are for converting kinetic energy of flowing water into electricity. The power plant has at least one turbine house defining a duct for housing a turbine apparatus, and a connecting means for attaching the turbine apparatus in the duct. The connecting ...

Metodo per la produzione di un substrato con una pellicola di rivestimento di primer attaccata ad esso, e metodo per la produzione di un substrato con una pellicola di rivestimento ...

La maggior parte delle eliche navali sono costruite con metalli non ferrosi, come ad esempio composti di rame, ottone o acciaio inossidabile. Nel lungo periodo l'esposizione delle superfici delle eliche all’acqua di mare permette a vari organismi acquatici come le ostriche, i mitili, i cirripedi, le ...

Severe Decompression Sickness Associated with Shock and Acute Respiratory Failure

Decompression sickness (DCS) is a well-recognized complication of diving but rarely results in shock or respiratory failure. We report a case of severe DCS in a diver associated with shock and respiratory failure requiring mechanical ventilation. A healthy 50-year-old male diver dove to a depth of 218 feet ...

Effect of Brine Concentrations on the Bacteriological and Chemical Quality and Histamine Content of Brined and Dried Milkfish

In this research, the occurrence of hygienic quality and histamine in commercial brined and dried milkfish products, and the effects of brine concentrations on the quality of brined and dried milkfish, were studied. Brined and dried milkfish products (n = 20) collected from four retail stores in Taiwan ...

Mobile-based Fish Quality Detection System Using K-Nearest Neighbors Method

Mujair fish (Oreochromis Mossambicus) is a popular consumption fish in Indonesia. The fish is a freshwater fish found in rivers, ponds, and lakes, with a salinity of less than 0.05% for the breed. Mujair fish is widely consumed by the public as a cheap and tasty fish that is often found in traditional ...

Semi-automatic Approach to Create Fish Image Datasets for Aquaculture Applications

Continuous monitoring of wild fish populations and their interaction with farmed fish is important, not only for marine biologists, but also for the aquaculture sector. Nowadays many efforts are made in trying to recognize fish species under-water effectively. Different techniques of computer vision ...

Rapid Domoic Acid Depuration in the Scallop Argopecten purpuratus and Its Transfer from the Digestive Gland to Other Organs

Domoic acid (DA), the main toxin responsible for Amnesic Shellfish Poisoning, frequently affects the marine resources of Chile and other countries across the South Pacific, thus becoming a risk for human health. One of the affected resources is the scallop Argopecten purpuratus. Even though this species ...

Ecosystem service lens reveals diverse community values of small-scale fisheries

The ocean provides benefits to coastal communities around the world, however, the depth and complexity of people’s interactions with marine ecosystems are not well represented in many marine management initiatives. Many fisheries are managed to maximize provisioning value, which is readily quantified, ...

Molecular Identification of Zoonotic Parasites of the Genus Anisakis (Nematoda: Anisakidae) from Fish of the Southeastern Pacific Ocean (Off Peru Coast)

The study aims to perform, for the first time, the molecular identification of anisakid larvae in commercial fish from the Southeastern Pacific Ocean off the Peru coast, and to provide data on their infection level by fishing ground, fish host, and site of infection. Fish specimens (N = 348) from the ...

A spider in motion: facets of sensory guidance

Spiders show a broad range of motions in addition to walking and running with their eight coordinated legs taking them towards their resources and away from danger. The usefulness of all these motions depends on the ability to control and adjust them to changing environmental conditions. A remarkable ...

Prevalence and correlates of HIV infection among adolescents and young people living in fishing populations along Lake Victoria Fishing Communities in Uganda

Introduction fishing communities in Uganda are key populations for HIV, with persistently higher prevalence and incidence than the general population. Methods between March and August 2014, a cross sectional survey was conducted in 10 fishing communities of Lake Victoria in Uganda. Data was collected ...

Marine conservation: towards a multi-layered network approach

Valuing, managing and conserving marine biodiversity and a full range of ecosystem services is at the forefront of research and policy agendas. However, biodiversity is being lost at up to a thousand times the average background rate. Traditional disciplinary and siloed conservation approaches are not ...

Individual variation and interactions explain food web responses to global warming

Understanding food web responses to global warming, and their consequences for conservation and management, requires knowledge on how responses vary both among and within species. Warming can reduce both species richness and biomass production. However, warming responses observed at different levels ...

Cross-continental analysis of coastal biodiversity change

Whereas the anthropogenic impact on marine biodiversity is undebated, the quantification and prediction of this change are not trivial. Simple traditional measures of biodiversity (e.g. richness, diversity indices) do not capture the magnitude and direction of changes in species or functional composition. ...

Impacts of stormwater on coastal ecosystems: the need to match the scales of management objectives and solutions

Despite their limited area relative to the global ocean, coastal zones—the regions where land meets the sea—play a disproportionately important role in generating ecosystem services. However, coastal ecosystems are under increasing pressure from human populations. In particular, urban stormwater is ...

Citizen science and marine conservation: a global review

Climate change, overfishing, marine pollution and other anthropogenic drivers threaten our global oceans. More effective efforts are urgently required to improve the capacity of marine conservation action worldwide, as highlighted by the United Nations Decade of Ocean Science for Sustainable Development ...

The current knowledge gap on metallothionein mediated metal-detoxification in Elasmobranchs

Elasmobranchs are particularly vulnerable to environmental contamination, especially pollutants that may bioaccumulate and biomagnify, throughout the trophic web, such as metals. However, Elasmobranch management and conservation plans are challenging, and this group is often neglected regarding ecotoxicological ...

Urban gulls adapt foraging schedule to human-activity patterns

Numerous animals are able to adapt to temporal patterns in natural food availability, but whether species living in relatively novel environments such as cities can adapt to anthropogenic activity cycles is less well understood. We aimed to assess the extent to which urban gulls have adapted their foraging ...

Using a Bayesian modelling approach (INLA-SPDE) to predict the occurrence of the Spinetail Devil Ray (Mobular mobular)

To protect the most vulnerable marine species it is essential to have an understanding of their spatiotemporal distributions. In recent decades, Bayesian statistics have been successfully used to quantify uncertainty surrounding identified areas of interest for bycatch species. However, conventional ...
