We teach a real robot to grasp real fish, by training a virtual robot exclusively in virtual reality. Our approach implements robot imitation learning from a human supervisor in virtual reality. A deep 3D convolutional neural network computes grasps from a 3D occupancy grid obtained from depth imaging ...
In this paper, we report the initial study to design and development of long-range wireless communication system based on LoRa technology for Indonesian fishermen in which the targeted ship is under <5 GT (small-ship category). The developed system consists of 1) customizable end-node; 2) Android ...
Coastal erosion is a major problem faced by the coastal population. Kadalur villages located in the South East coast of India are one such coastal site subjected to large scale erosion. National Institute of Ocean Technology (NIOT) has monitored the shoreline changes along this coast for more than 5 ...
Dynamic-analysis results of a 300-m-long bottom-set gillnet are presented under wave excitations and current. A bottom-set-gillnet design is based on one of existing types utilized in South Korea. Environmental conditions are chosen based on measured wave and current data obtained from the southwest ...
This paper presents the hydrodynamics performance of traditional small fishing vessel with the capacity of 3 GT operated in the coastal area of Surabaya. Regarding with the new Indonesian regulation, the small vessels of less than 5 GT are eligible to achieve the fishing area of up to 12 nm from the ...
The MesoAmerican Reef (MAR) and the Great Barrier Reef (GBR) are the two largest reef systems in the world yet MAR lags far behind in research and recognition. GBR has over ten times more research published than MAR, and this disparity has been consistent across decades. GBR benefits from a high level ...
The Mid-Atlantic Regional Council on the Ocean (MARCO) was established in 2009 to enhance the vitality of the region's ocean ecosystem and economy. One of MARCO’s first action items was the development of the Mid-Atlantic Ocean Data Portal (ODP) to serve as an online platform to engage stakeholders ...
This paper proposes an IoT active acoustic system for fish monitoring with direct application in biodiversity preservation near hydropower plants and dams. The system employs a cost effective single board computer as central processing unit. The acoustic signal processing is performed at two levels: ...
River watersheds are among the most complex terrestrial features in Alaska, performing valuable ecosystem functions and providing services for human society. Rivers are vital to both estuarine and aquatic biota and play important roles in biogeochemical cycles and physical processes. The functions of ...
Anthropogenic noise can negatively impact many taxa worldwide. It is possible that in noisy, high-disturbance environments, the range and severity of impacts could diminish over time, but the influence of previous disturbance remains untested in natural conditions. This study demonstrates the effects ...
Underwater gliders have become a critical component of coastal observing systems for measuring water column properties. They efficiently sample from the surface to the seafloor or their depth limit collecting essential density variables for weeks to months at a time, providing invaluable information ...
It is widely accepted that Vessel Monitoring Systems (VMS) are currently a fundamental tool in the control of fishing activity. While larger vessels, because of their fishing capabilities, are the main target of this control, it is starting to be clear that by not monitoring smaller vessels, an important ...
Abstract We investigated the impact of native freshwater mussel assemblages (order Unionoida) on the abundance and composition of nitrogen‐cycling genes in sediment of an upper Mississippi river habitat. We hypothesized that the genomic potential for ammonia and nitrite oxidation would be greater in ...
Abstract Streptococcus agalactiae is a highly pathogenic bacterium of aquatic species and terrestrial animals worldwide, whereas chitin and its derivative chitosan are among the most abundant biopolymers found in nature, including the aquatic milieu. The present investigation focused on the capability ...
Abstract Rapid increase in lake temperature can cause a shift toward the dominance of warm temperature tolerant species, including Cyanobacteria that are deficient in polyunsaturated fatty acids (PUFA) supporting consumer growth and reproduction. To increase our understanding of how changes in physicochemical ...
The study aimed to evaluate the chemical composition and nutraceutical potential of two commercially significant edible bivalve mollusc species (Anadara broughtonii and Mactra chinensis). The edible parts (motor muscle, mantle and adductor) of these molluscs were analyzed for their proximate composition, ...
While the goal of most conservation hatchery programs is to produce fish that are genetically and phenotypically indistinguishable from the wild stocks they aim to restore, there is considerable evidence that salmon and steelhead reared in hatcheries differ from wild fish in phenotypic traits related ...
ABSTRACT Targeted genome editing by CRISPR/Cas9 is extremely well fitted to generate gene disruptions, although precise sequence replacement by CRISPR/Cas9-mediated homology-directed repair (HDR) suffers from low efficiency, impeding its use for high-throughput knock-in disease modeling. In this study, ...
ABSTRACT Prolonged hyperglycemia can alter retinal function, ultimately resulting in blindness. Adult zebrafish adults exposed to alternating conditions of 2% glucose/0% glucose display a 3× increase in blood sugar levels. After 4 weeks of treatment, electroretinograms (ERGs) were recorded from isolated, ...
Hot water was used to obtain Chlorella sorokiniana hot water extract (HWE). Subsequently, this byproduct was freeze-dried, hydrolysed at 50 °C using Protease N to obtain C. sorokiniana protein hydrolysates (PN-1), and then digested with a gastrointestinal enzyme (PN-1G). The inhibitory effects of the ...
