Fishing and resource use continues to be an essential aspect of life for many Aboriginal communities throughout Australia. It is important for dietary sustenance, and also retains deep social, cultural and economic significance, playing a fundamental role in maintaining group cohesion, transferring ...
Worldwide, increasing coastal development has played a major role in shaping coral reef species assemblages, but the mechanisms underpinning distribution patterns remain poorly understood. Recent research demonstrated delayed development in larval fishes exposed to suspended sediment, highlighting the ...
The adaptation of fish to low temperatures is the result of long-term evolution. Amur carp (Cyprinus carpio haematopterus) survives low temperatures (0-4°C) for six months per year. Therefore, we chose this fish as a model organism to study the mechanisms of cold-adaptive responses using high-throughput ...
Modified handling is often claimed to reduce (sub-)lethal impacts among organisms caught-and-released in fisheries. Improving welfare of discarded fish warrants investigation, when their survival is of both economic and ecological importance. In this study, juvenile yellowfin bream (Acanthopagrus australis) ...
Salmonella spp. can indirectly infect humans via transfer from animals and animal-derived food products, and thereby cause potentially fatal diseases. Therefore, gaining an understanding of Salmonella infection in farm animals is increasingly important. The aim of this study was to identify the distribution ...
Several research initiatives have been undertaken to map fishing effort at high spatial resolution using the Vessel Monitoring System (VMS). An alternative to the VMS is represented by the Automatic Identification System (AIS), which in the EU became compulsory in May 2014 for all fishing vessels of ...
Abstract Breakwater structure deterioration or damages can jeopardize dike safety and function. To manage breakwater maintenance and enhance work efficiency, we integrated cloud computing into a breakwater inspection system. The purpose was to facilitate the efficient management of breakwater maintenance. ...
Abstract Rigid jumpers are typically used to provide fluid conduit between different subsea equipment, and are an important part of the subsea oil and gas field development. Although numerous rigid jumpers have been successfully designed and installed, rigid jumper design for corrosive hydrocarbon ...
Abstract The insufficient fatigue strength is one of the main causes of overall damage to ship hulls. The plastic deformation of ship plates will accumulate under extreme wave load and the low-cycle fatigue crack appears in the local zone of ship plates when the accumulative plastic deformation reached ...
Abstract The stiffened plate is the most fundamental structure which is widely used at marine industry such as ship hull or offshore topside structure. It is of great importance to study the dynamic response of stiffened plates subjected to explosion loading. In this paper, the theoretical analysis ...
Abstract This paper introduces the approach to develop a trawl boat with skeg. RANS solution was adopted to predict the powering performance of the trawl boat numerically, also self-propulsion tests of the hull with skeg were performed in towing tank to verify the numerical results and evaluate the ...
Abstract The growth in the capacity of offshore wind power units in Europe has leveled off in recent years. Analysis has indicated that this may be because development in the coastal waters is nearing saturation or because of risks and technical barriers. For example, the United Kingdom's Round 3 is ...
Abstract An updated accident database with 789 overall waterway accidents from 1981–2013 at Chittagong Port (CP) in Bangladesh shows around 48% accidents were collision. In this paper, collision risk in CP is analyzed by constructing collision frequency calculation models that are solved using IWRAP ...
Abstract Extreme waves up to 30 m are dangerous for ships and marine engineering structures. During 2006–2010 years the 78 cases have been registered in different sites of the World ocean. From design point of view, it is interesting to know the extreme wave environment, corresponding impact loads ...
Abstract Numerical predictions given by the Neumann-Michell linear-potentialflow theory have previously been reported and found to be in good overall agreement with experimental measurements of the drag, the sinkage and the trim experienced by a number of monohull ships, as well as the wave profiles ...
Abstract This research applied CFD solver naoe-FOAM-SJTU and NMShip- SJTU solver which based on the Neumann-Michell theory to forecast the drags, sinkage and trim experienced by several ship hulls that steadily advance along a straight path at constant speeds in infinite calm water. We explore the ...
Abstract The present work is focused on the numerical simulation of an oblique towed ship using Unsteady Reynolds Averaged Naver-Stokes(URANS) method. The numerical computations are carried out by using the solver naoe-FOAM-SJTU, which is developed for ship and ocean engineering based on the open source ...
Abstract Red tides off the Japanese coast caused serious damages to aquaculture industries in every year (Honjo 1994). To reduce fisheries damage due to red tide, it is important to inform aquaculturist of red tides in short-term scale distribution. We developed a monitoring system which collects real-time ...
Abstract Naturally occurring shoals and near-shore reefs act as good wave attenuators. Artificial creations of such nature identical attenuators are called artificial reefs. They are being increasingly deployed since the past decade, as artificial reefs may be included under soft engineering approach ...
Abstract Offshore cages are designed to avoid further negative environmental damage in the coastal area while enable sustainable aquaculture growth. However, little is known about the environmental impact from this culturing activity in China. The objective of this study is to simulate the environmental ...
