Long-term monitoring of Indus River Dolphin (IRD) is critical to enable and make informed decisions on current habitat. However, existing literature on underwater acoustic sensor network (UASN) based sensing and activation is limited. Most recently canal entrapment has lacked to recover 2–7 dolphins ...
This Paper explores the current use of Massive Open Online Courses (MOOCs) as a means of educational outreach among identified remote populations in Southeast Asia. Often excluded from traditional educational outreach, these groups are targeted through the COMPETEN-SEA Project, a Capacity Building in ...
The method of visual analysis, which provides detection of contours and clusterization of objects of interest optimized for real-time operation is offered in this paper. The method is intended for use in oceanographic equipment to estimate the abundance and dynamics of plankton spatial distribution ...
Nord Stream 2 Company carried out an Environmental Impact Assessment (EIA) to compare alternative location routes of the Russian part of the project Nord Stream 2 gas pipeline in April 2017 in Russia. Lengths of the alternative routes for new marine gas pipeline varied from 1230 km to 1260 km. During ...
To address the species decline in aboriginal fish in the Yarlung Tsangpo River Basin and the lack of research on the habitat characteristics of fish spawning grounds, this paper studied the changing trends in runoff in spawning grounds and the habitat conditions characteristics of Schizopygopsis younghusbandi ...
Tuna industry is developing rapidly in recent years, and it had became a important growth point of the fisheries in China, this paper use the SCP analysis paradigm, emphatically analyzed the market structure of tuna imports market in China and explored the tuna imports market present situation and its ...
IoT application protocols have a vital role to play while designing and building an IoT system. As the application changes, the functionalities that the protocols have to deliver will also change. We plan to build a marine IoT system by installing environmental monitoring stations on fishing vessels. ...
Hybrid propulsion is a crucial technology for the propulsion of underwater vehicle. The disadvantages of the underwater vehicle driven by propellers are that the thrust is difficult to control and the vision is easy to blurry by the sediment on the seabed. First, a new propulsion system that combined ...
In this paper, we propose image analysis based methods for estimating fish tail beat frequency, which is an indicator of fish energy consumption at fish passage structures. For this purpose, average magnitude difference and autocorrelation function based periodicity detection techniques are utilized. ...
Evaluating environmental policies requires estimating the impacts of policy-induced changes on ecological and human systems. Drawing connections between biophysical and economic models is complex due to the multidisciplinary nature of the task and the lack of data. Further, time and resource constraints ...
Abstract The twin tail of ornamental goldfish is known to be caused by a nonsense mutation in one chordin paralogue gene. Our previous molecular studies in goldfish revealed that the ancestral chordin gene was duplicated, creating the chdA and chdB genes, and the subsequent introduction of a stop codon ...
Abstract Performance and body composition of insect larvae depend on quality and quantity of their diet, and on biotic factors such as larval density. We investigated the effect of dietary nutrient concentration and larval rearing density on survival, development, growth, and protein and fat contents ...
The present study aimed to reveal the eukaryotic diets of two economically important marine sediment-inhabiting worms, Sipunculus nudus (peanut worm) and Urechis unicinctus (spoon worm), using clone libraries and phylogenetic analyses of 18S rRNA genes. Fungal rDNA was also targeted and analyzed to ...
A dissimilatory nitrate reduction to ammonium (DNRA) microbial community was developed under a high organic carbon to nitrate (C/NO3−) ratio in an anoxic semi-continuous sequencing batch reactor (SBR) fed with glucose as the source of carbon and NO3− as the electron acceptor. Activated sludge collected ...
This study characterized microbiological and chemical contamination of oyster meat and estuarine water in Phang Nga, Thailand. Pooled oyster meats (n = 144), estuarine waters (n = 96) and environmental parameters were collected from March, 2016 to February, 2017, and assessed for levels of total coliforms ...
In this study, the interaction between the humus and two antibiotics was studied by UV-Vis spectroscopy to describe the interaction mechanism and the effects of different environmental factors on the mechanism. Results showed that humic acid (HA) containing more aromatic groups was easily associated ...
Previously, we showed that chitosan could augment the biocidal efficacy mediated by photodynamic treatment against Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. In this study, we showed that the antimicrobial action of chitosan in augmenting photodynamic inactivation (PDI) is ...
This study investigated the profile of the autochthonous gut bacterial communities in adult individuals of Sparus aurata and Dicentrarchus labrax reared in sea cages in five distantly located aquaculture farms in Greece and determine the impact of geographic location on them in order to detect the core ...
Aurantiochytrium sp. PKU#SW7 is a thraustochytrid strain that was found to exhibit high potential for docosahexaenoic acid (DHA, C22:6n-3) production. In this work, the transcriptome of Aurantiochytrium sp. PKU#SW7 was analyzed for the study of genes involved in basic metabolic functions and especially ...
Livestock production and Animal-Source Foods (ASFs) like meat, milk, and eggs are excellent sources of essential micronutrients, including iron and zinc. There is evidence that encouraging increased access to and consumption of these ASFs may either positively or negatively impact anemia, or have no ...
