Rapid hypoxia of the aquaculture water is one of the important factors that cause large area death of the aquaculture animals. The monitoring for the dissolved oxygen (DO) of the aquaculture water is very important to the safety of the aquaculture production. An intelligent monitoring system for DO ...
In the detection of dissolved oxygen(DO) concentration based on the principle of fluorescence quenching, fluorescence intensity detection generally relies on high-precision instruments, extra amplifier circuits and filter circuits at present, which make the detection cost high and the structure complex. ...
Presents the table of contents/splash page of the proceedings record.
Aquaculture is one of the fastest growing food sectors worldwide providing more than 50% of world fish consumption. Towards sustainable development, aquaculture ought to design and implement technical solutions for the efficient management of farms, thus improving fish performance and decreasing operational ...
This work examines authentication in underwater acoustic networking scenario. Taking a nontraditional approach to meet authenticity requirements, a scheme is proposed which includes not only intrusion prevention but also intrusion tolerance to some degree, called Fair Authentic Acoustic Network Grouping ...
Do cephalopods change colour when under distress? How to measure heart rate simultaneously on the three hearts of a oyster? This manuscript introduces and discusses the challenges veterinarians face daily when assessing and treating animals and the opportunities to overcome these challenges utilizing ...
In fisheries industry, flatfish accounts for about half of the domestic fish production and is a specie with active aquaculture activities. As flatfish grows, classification according to the size should be periodically carried out for efficient growth. In this paper, the correlation between area and ...
This paper proposes a counting system for estimating the biomass of nursery-stage pacific white shrimp in an indoor cultured tank using an image processing technique. The outcome is to reduce an over feed and water quality issue. As a result, it leads to the reduction of an operation cost in an indoor ...
This paper deals with the problem of tracking a single trespasser on a fish farm moving through Underwater Wireless Sensor Networks(UWSNs) by employing underwater acoustic sensors. This paper addresses the issues of estimating the states of a trespasser, and improving energy efficiency by applying the ...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Presents the 2018 subject/author index for this publication.
Colonies of the red sea pen Pennatula rubra sampled by trawling in the northwestern Mediterranean Sea were analyzed. Biometric parameters such as total length, rachis length, number of polyp leaves, wet weight and dry weight were measured and related to each other by means of regression analysis. The ...
The present work shows and discusses a monitoring system installed in a vulnerable coastal basin, named Mar Grande, located in Southern Italy, affected by human and industrial pressures.The most recent collected data are processed and analyzed to detect the evolution of the examined parameters in the ...
Maritime Spatial Planning has become an essential requirement in order to ensure and contribute to the protection of the marine environment. The challenge is to regulate economic interests by simultaneously ensuring appropriate levels of safety for the various off-shore activities in coastal and open ...
Allelochemicals are the media of allelopathy and form the chemical bases of plant-environment interactions. To determine true allelochemicals and their autotoxic effects, seven compounds were isolated and identified from in-situ sampled rhizosphere soil of cultivated Saussurea lappa. Of these; costunolide ...
The intent of the present work was to evaluate the potential of four macroalgae prevalent in Europe, namely Ulva rigida, Gracilaria sp., Fucus vesiculosus and Saccharina latissima, for application in functional foods, either in the direct form or as extracts. Accordingly, nutritional composition, the ...
Abstract Preinfection by one parasitic species may facilitate or by contrast hamper the subsequent penetration and/or establishment of other parasites in a host. The biology of interacting species, timing of preinfection, and dosage of subsequent parasite exposure are likely important variables in ...
Electronic monitoring of fishery activities has drawn increasing attention. Deformable objects, noise from the wild sea surface, and dynamic background, however, make conventional tracking and segmentation methods unreliable. In this paper, we present an online 3D tracking and segmentation system for ...
Polar benzotriazoles are corrosion inhibitors with widespread use; they are environmentally characterized as emerging pollutants in the water system, where they are present in low concentrations. Various extraction methods have been used for their separation from various matrices, ranging from classical ...
