In this paper, we propose an ICT application of real-time monitoring system to estimate the catch amount within set-net. Generally, set-net fishermen do not know the catch amount in advance before arriving to set-net area, in which they tend to unable to perform the fishing operation effectively. It ...
The paper presents a mathematical model of optimal fleet number of fishing vessels. Here we consider two aspects related to the vessels and to the fish stock to which the vessels are used to exploit to. The first aspect is the availability/reliability of the vessels. The fishing vessels are vital equipment ...
One approach to the management of common fish diseases in aquaculture is the use of antibiotic-laden feed. However, there are public concerns about the use of antibiotics in agriculture and the potential development of antibiotic resistant bacteria. Therefore, the discovery of other environmentally ...
Aim: This work was aimed to document the antiviral activates of Spirulina platensis extract against foot and mouth disease virus (FMDV) different types to evaluate its replication in Baby Hamster Kidney (BHK) cell culture and in baby mice. Materials and Methods: Cytotoxicity assay studied for S. ...
The present study investigates the effects of different routes of inulin administration as prebiotic on gut microbiota and survival rate of Indian white shrimp post-larvae. Four hundred and fifty Indian white shrimp post-larvae (PL1) were stocked in nine tanks. The tanks were assigned into three treatments: ...
Abstract Even though aluminum is the third most common element present in the earth's crust, information regarding its toxicity remains scarce. It is known that in certain cases, aluminum is neurotoxic, but its effect in other tissues is unknown. The aim of this work was to analyze the genotoxic potential ...
The grass carp (Ctenopharyngodon idellus) is an important species in freshwater aquaculture both in China and on a global scale. Variety degeneration and frequent diseases have limited the further development of grass carp aquaculture. Thus, new and improved varieties are required. Here, we identified ...
The final effluents of two wastewater treatment plants (WWTPs) in the Eastern Cape Province of South Africa were evaluated for their physicochemical and microbiological qualities over a period of 12 months. The physicochemical parameters assessed ranged as follows both plants. The ranges of values for ...
The use of wastewater and excreta in agriculture is a common practice in Southeast Asia; however, concerns remain about the potential public health risks of this practice. We undertook a scoping review to examine the extent, range, and nature of literature, as well as synthesize the evidence for associations ...
This study examines the groundwater quality in wells situated near agricultural fields in Saudi Arabia. Fruits (e.g., tomato and green pepper) irrigated with groundwater were also assessed for the occurrence of opportunistic pathogens to determine if food safety was compromised by the groundwater. The ...
Objective The bacterium Oceanimonas sp. (O. sp.) GK1 is a member of the Aeromonadaceae family and its genome represents several virulence genes involved in fish and human pathogenicity. In this original research study we aimed to identify and characterize the putative virulence factors and pathogenicity ...
Bleaching episodes caused by increasing seawater temperatures may induce mass coral mortality and are regarded as one of the biggest threats to coral reef ecosystems worldwide. The current consensus is that this phenomenon results from enhanced production of harmful reactive oxygen species (ROS) that ...
The Center for the Integrated Modeling and Analysis of the Gulf Ecosystem I and II (C-IMAGE I and II) are two of fourteen centers funded by the Gulf of Mexico Research Initiative (GoMRI) investigating the shortand long-term impacts of submarine oil spills on the Gulf of Mexico Ecosystem. C-IMAGE researchers ...
This paper presents a methodology for localizing an autonomous tethered underwater robotic vehicle deployed for aquaculture inspection operations. The developed methodology is based on an Asynchronous Unscented Kalman Filer (UKF) to fuse information from onboard sensors along with a'priori knowledge ...
The Ocean Tracking Network (OTN) is a global research and technology development platform headquartered at Dalhousie University, in Halifax, Nova Scotia. OTN uses electronic telemetry to document the local-to-global movements and survival of aquatic animals, and to link them to environmental correlates. ...
This paper will report on the strengths and weaknesses of each method and suggest methods for blending the results of these multiple methods to produce more nuanced attribute-rich spatial data on human uses and valuation of the estuarine environment.
Farming of Atlantic salmon in exposed areas poses unique challenges to operations, structures and equipment due to severe and irregular wind, wave and current conditions, and sheer remoteness. Many of the operational challenges seen at present sheltered sites are likely to be amplified when moving production ...
Pelagic Sargassum macroalgae entrained in the Gulf Stream serves as habitat for commercially and recreationally important fish and protected sea turtles, among other organisms. It also plays an important role in the sourcing of carbon, nitrogen, and phosphorus to the otherwise deficient oligotrophic ...
Increased use of autonomy is considered crucial for continued growth in maritime industries like oil- and gas, waterborne transport, and fisheries- and aquaculture. This article presents a method called Autonomous Job Analysis (AJA), which purpose is to guide the design of autonomous marine operations. ...
The SEATONOMY methodology provides a structured approach for design, development and validation of mobile autonomous maritime operations and systems. The goal is to achieve this by providing system developers of autonomous systems with suitable guidelines, principles, best practices and tools. The methodology ...
