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 ...
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 ...
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 ...
Cetaceans rely critically on sound for navigation, foraging and communication and are therefore potentially affected by increasing noise levels from human activities at sea. Shipping is the main contributor of anthropogenic noise underwater, but studies of shipping noise effects have primarily considered ...
The economic and societal impacts of nano-materials are enormous. However, releasing such materials in the environment could be detrimental to human health and the ecological biosphere. Here we demonstrate that gold and quantum dots nanoparticles bio-accumulate into mucus materials coming from natural ...
Background Characterisation of the bacterial composition of the gut microbiota is increasingly carried out with a view to establish the role of different bacterial species in causation or prevention of disease. It is thus essential that the methods used to determine the microbial composition are robust. ...
The slower is faster (SIF) effect occurs when a system performs worse as its components try to do better. Thus, a moderate individual efficiency actually leads to a better systemic performance. The SIF effect takes place in a variety of phenomena. We review studies and examples of the SIF effect in ...
Apparecchiatura per sgusciare gamberi, comprendente un dispositivo di trasporto (1) dei gamberi rotante, prowisto di un organo motore (11) e di una pluralita di pinze (2), atte a trattenere i gamberi durante la loro movimentazione, ed un supporto fisso (3), atto a sostenere almeno una stazione (40; ...
Abstract Diet analysis is an important aspect when investigating the ecology of fish‐eating animals and essential for assessing their functional role in food webs across aquatic and terrestrial ecosystems. The identification of fish remains in dietary samples, however, can be time‐consuming and unsatisfying ...
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 ...
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 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 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 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 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 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 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 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 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 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 ...
