This paper presents the development of a bio-inspired swimming robot from concept design to simulation for marine aquaculture applications. Based on investigation of several fish motions, the Manta ray is found to be the most suitable mock object since the flapping pectoral fin features long-endurance, low noise, high payload capacity, good stability and maneuverability. Through a comprehensive analysis...
Intensive cultures of shrimps produce more than 10 individuals per square meters with the use of hatchery reared post-larvae and the supply of compounded diets. The paddle wheel aerators are usually installed in the pond to supply oxygen and collect the sludge generated from the excretion of shrimps and the rest of the compounded food. The operation of paddlewheel aerators consume plenty of oil or...
This paper used DIDSON to get information of underwater fish and carried out the real-time multiple-target tracking, particularly the targets were dense. Analysis of fishery resources was also done through the data post-processing. Realtime data processing mainly included DIDSON image building/enhancement/filter, target detection and multiple-target tracking. Nearest neighbor clustering algorithm...
On the background of the compilation of a new round MFZ(marine functional zoning) in Tangshan, this paper take the method of integrating onsite survey and remote sensing survey, comprehensively considers the status quo of marine development and utilization, marine natural environment, social needs, economic and technical feasibility, then evaluates the existing natural coastline in Tangshan and defined...
Research on the influence of specific hydrological environment change on current velocity and water exchange has a long history in oceanography; however, the majority of previous work has been based on traditional ocean models such as POM and FVCOM. This paper presents a stable joint method that combines a support vector machine with a hydrological model to predict current velocity in different hydrological...
Brominated flame retardants (BFRs) are ubiquitous industrial chemicals likely to persistently exist in the environment, bioaccumulate in food chains, and even may cause adverse health effects in human. Borgundfjorden fjord system, an important spawning ground for the Norwegian coastal cod (Gadus morhua) stock, was contaminated by significant levels of pollutants such as BFRs, due to the local previous...
As the main nutrient inputs of ECS, nutrient concentrations of the Yangtze River increase significantly due to high-speed economy development, which play a very important impact on the East China Sea ecosystem. In this study, by integrating MEC model and Ecosim model, we analyzed the impacts of Yangtze nutrient fluxes change and fishery on the ecosystem of ECS. The results show that in only consideration...
