Knowledge about fish behavior is crucial to be able to influence the capture process and catch species composition. The rapid expansion of the use of underwater cameras has facilitated unprecedented opportunities for studying the behavior of species interacting with fishing gears in their natural environment. ...
The Internet of Underwater Things (IoUT) is an emerging communication ecosystem developed for connecting underwater objects in maritime and underwater environments. The IoUT technology is intricately linked with intelligent boats and ships, smart shores and oceans, automatic marine transportations, ...
Harmful algal blooms (HABs) are a rising health and environmental concern in the United States, particularly in South Florida. Skin contact and the ingestion of contaminated water or fish and other seafood have been proven to have severe toxicity to humans in some cases. However, the impact of aerosolized ...
Simple Summary The parasites of the Anisakidae family infest mainly marine mammals; however, they have the ability to infest paratenic hosts such as mollusks, small crustaceans and fish. The consumption of meat from animals of aquatic origin favors the acquisition of the disease known as Anisakiasis ...
Abstract For more than 10 years (2007-2018), the benthic macroinvertebrates of Bahía de Chamela (Mexican Pacific) were sampled at 31 sites (0-25 m depth). A total of 308 species of the five main classes of benthic molluscs were obtained (106 bivalves, 185 gastropods, 13 polyplacophorans, two scaphopods ...
Parasitic nematode infections cause debilitating diseases and impede economic productivity. Antinematode chemotherapies are fundamental to modern medicine and are also important for industries including agriculture, aquaculture and animal health. However, the lack of suitable treatments for some diseases ...
In this paper, we introduce a generative model for image enhancement specifically for improving diver detection in the underwater domain. In particular, we present a model that integrates generative adversarial network (GAN)-based image enhancement with the diver detection task. Our proposed approach ...
Abstract The complex biogeographical history of the Balkan Peninsula caused remarkable freshwater fish diversity and endemism, among which Cyprinidae fish dominate. The Dinaric karst was a Pleistocene refugium and it harbors ancient and endemic cyprinids, including Aulopyge huegelii, a sole representative ...
In this paper, an output-feedback fuzzy adaptive dynamic surface controller (FADSC) based on fuzzy adaptive extended state observer (FAESO) is proposed for autonomous underwater vehicle (AUV) systems in the presence of external disturbances, parameter uncertainties, measurement noises and actuator faults. ...
Mating strategies in fishes are known to include polygyny, polyandry and monogamy and provide valuable insights regarding powerful evolutionary forces such as sexual selection. Monogamy is a complex of mating systems that has been relatively neglected. Previous work on mating strategies in fishes has ...
The meso-scale habitat simulation model MesoHABSIM was applied in three Lithuanian lowland rivers to study the effect of low-head hydropower plants (HPPs) on the fish habitats. Stream flow time series on a daily scale for the period 1970–2015 were used to describe flow regime downstream of HPPs for ...
Illegal fishing is a global problem affecting society in numerous ways: from impacting the sustainability of artisanal and subsistence fishing communities to disturbing the balance of delicate oceanic ecosystems through the systematic overexploitation of fish stocks. On a global level, the success criminal ...
Our study presents a tool to improve a ship hull form parameter based on genetic optimization algorithms from an existing ship or a parent ship. In this research, a mathematical model of an objective function is obtained using the Holtrop prediction method’s viscous resistance and wave resistance. In ...
Marine reserves constitute effective tools for preserving fish stocks and associated human benefits. However, not all reserves perform equally, and predicting the response of marine communities to management actions in the long run is challenging. Our decadal-scale survey of recreational fishing yields ...
Classifying and detecting fishes in the wild is still an issue because of the various poses of fishes, ungovernable environment factors and the restricted quantity of data for training the model. The paper proposes an analysis of the techniques to classify different types of fishes caught on fishing ...
Indonesia as a state maritime country has the largest ocean in the world and locates between two continents and two oceans (Figure 1). As a state maritime, Indonesia has a source power of nature which is very large both on land and at sea. Utilization of source power in waters particularly about catching ...
The invention relates to a machine operating element (1) with safety functionality comprising a safety characteristic detection means (3) on a supporting structure (2), the supporting structure (2) being arranged in or on an item of clothing, which item of clothing can be arranged on a body part performing ...
A method of operating an inflation system is provided. The method includes recognizing that the inflation system is activated or actuated by a user, supplying current to an electromagnet of a solenoid valve of the inflation system such that an armature-valve element of the solenoid valve is moved to ...
A tugboat for assisting a marine vessel to maneuver. The tugboat boat comprises an engine driving one or more propulsors with a controllable direction of thrust, a towing line for establishing a pulling connection between an assisted vessel and the tugboat, a first sensor arrangement configured for ...
Temporal variability of the genetic structure and connectivity patterns of the blue and red shrimp Aristeus antennatus in the seven most important fishing grounds of the Western Mediterranean Sea, were assessed using twelve microsatellite loci during 2 consecutive years (2016 and 2017), in a total of ...
