Abstract Fishing represents a major problem for conservation of chondrichthyans, with a quarter of all species being overexploited. School sharks, Galeorhinus galeus, are targeted by commercial fisheries in Australia and New Zealand. The Australian stock has been depleted to below 20% of its virgin ...
Study region Mediterranean River Basins. Study focus Human activities and consequent pollution have put the freshwater and marine ecosystems of the Mediterranean region under pressure, with high risk of eutrophication phenomena. In this study, an extended version of the Geospatial Regression Equation ...
With numerous borders placed at various geographical locations, territorial boundaries are present to claim sovereignty and the resources present inside them. While territorial boundaries are physically present on lands, there still exists a virtual boundary system at sea. This paper proposes a system ...
The main goal of this project was to design a Portable Low Voltage Amplifier in which the amplification level is based on the signal strength being detected and was implemented with the use of analog filter, operational amplifiers and an analog multiplexer. Using this device, a portable data logger ...
Ships detection, as well as other object detection, and localization tasks in satellite images are the central problems in the field where remote sensing and computer vision coalesce. They are commonly used in different areas like environment monitoring, fishery management, logistics, insurance and ...
This article presents the prototype design and testing of a long-range, self-powered IoT devices for use in precision agriculture and aquaponics. The devices are designed using the ultra-low power nRF52840 microcontroller with Bluetooth 5 support and ambient energy harvesting. A power of 942μW is harvested ...
Illegal fishing poses an existential threat to global fisheries and is responsible for causing significant damage and depletion to fish stocks, food security and national economies. We describe a method through our agent-based high-level information fusion system to automate the detection of illegal ...
Saprolegnia spp. water molds severely impact fish health in aquaculture, fish farms and hobby fish tanks colonizing mature and immature stages of fishes, as well as eggs. Considering that there are no drugs licensed for treating and/or control the organism, efficient and environmental low-impact methods ...
Background: The relationship between dietary pattern and the risk of chronic obstructive pulmonary disease (COPD) has been described; however, the exclusive role of dietary factors remains controversial. Hence, we conducted this systematic meta-analysis to clarify the role of some nutrients and antioxidant ...
Toxoplasma gondii is a zoonotic protozoan parasite that can cause morbidity and mortality in humans, domestic animals, and terrestrial and aquatic wildlife. The environmentally robust oocyst stage of T. gondii is fundamentally critical to the parasite's success, both in terms of its worldwide distribution ...
Abstract The present study aimed to evaluate the biological responses of Colossoma macropomum to naphthalene injection and subsequent hypoxia exposure, emphasizing the expression of the tumor suppressor gene tp53. Tambaquis were intraperitoneally injected with naphthalene (50 mg/kg) and, after 96 hours, ...
Abstract Parodontidae is a small group of fish and some species are particularly difficult to identify due to the lack of sufficiently consistent morphological traits. Cytogenetically, the species possess 2n = 54 chromosomes and are either sex-homomorphic or sex-heteromorphic (regarding its chromosomes). ...
Epizootic haematopoietic necrosis virus (EHNV) was originally detected in Victoria, Australia in 1984. It spread rapidly over two decades with epidemic mortality events in wild redfin perch (Perca fluviatilis) and mild disease in farmed rainbow trout (Oncorhynchus mykiss) being documented across southeastern ...
The dataset describes the survey data on current adoption practices, readiness and willingness amongst woman fish vendors (WFVs) towards the adoption of m-commerce in Coastal Karnataka region, India. The coastal Karnataka belt houses three districts viz. Udupi, Uttara Kannada and Dakshina Kannada. Primary ...
Background Polyunsaturated fatty acids such as linoleic acid (LA) and α-linolenic acid (ALA) are abundant in vegetable oils and are important for human health. In the body, LA and ALA are respectively converted to the omega-6 fatty acid γ-linolenic acid (GLA) and the omega-3 fatty acid stearidonic ...
The creatine/phosphocreatine system is the principal energy buffer in mammals, but is scarcely documented in fish. We measured the gene expression of major enzymes of this system, glycine amidinotransferase (GATM), guanidinoacetate N-methyltransferase (GAMT) and muscle-type creatine kinase (CKM) in ...
The eradication of invasive exotic species is desirable but often infeasible. Here, we show that male guppies are a potential biological agent for eradicating invasive mosquitofish through the mechanism of reproductive interference, which is defined as any sexual behavior erratically directed at a different ...
Smart Fish Feeder is an automatic fish feeder that can be controlled using android smartphone. With this tool, fish owners will easily adjust the feeding schedule according to the recommended feed dose, and provide aquarium cleaning scheduling. In designing a fish feeder, there are some criteria such ...
The preliminary research about the implementation of Knowledge Growing System (KGS) in an Unmanned Aerial Vehicle (UAV) is described. The main topic of this research is maritime security monitoring. The lack of ocean monitoring systems due to a lack of human resources owned by the Government, resulting ...
Rapid convergence of traditional research areas of embedded systems, wireless sensor networks, control systems, automation, and sensors has enabled the evolution of Internet of Things (IoT). The concept of IoT is based on a self-configuring and adaptive system consisting of networks of sensors that ...
