Abstract:
... Mass mortality of the sea urchin Strongylocentrotus intermedius and consequent economic losses occur in the aquaculture industry due to the outbreak of black mouth disease. Decreasing the physical contact between the healthy and diseased sea urchins is proposed to be an effective approach to preventing the disease transmission. Laboratory experiments were designed to investigate whether different ...

Abstract:
... In recent years, as the abuse of antibiotics, hormones, and herbicides has worsened in aquaculture industry, it is important to monitor the concentrations of those trace contaminants in aquaculture water more effortlessly. The aim of this study was to develop a reliable sampling method for chemical monitoring in aquaculture ponds based on the technique of diffusive gradients in thin films (DGT). A ...

Abstract:
... Controlling sea lice (epeophtheirus salmonis) infestations has been a constant challenge encountered in the aquaculture industry. Currently, pesticides such as emamectin benzoate are widely employed due to their large safety margin and efficacy against all stages of sea lice. Unfortunately, the widespread use of emamectin benzoate has also led to resistance among sea lice. In this study, we presen ...

Abstract:
... Previous studies have shown that high-temperature treatment during thermosensitive periods (TSPs) induces >70% Nile tilapia to become pseudomales (XX phenotypic males) in all-XX families mainly by downregulating the 17β-estradiol (E2) levels. Commercially, methyltestosterone (MT) is used to induce the sex reversal of XX individuals in Nile tilapia and produce all-male larvae. In order to reduce th ...
... Edwardsiella piscicida is a widespread pathogen that infects a vast variety of fish species and causes hemorrhagic septicemia and significant property damage in the global aquaculture industry. E. piscicida employs type III and VI secretion systems (T3/T6SS) to penetrate and colonize macrophages, which are regulated by the EsrA-EsrB two-component system (TCS). In this study, we demonstrate that th ...

Abstract:
... Continuously improving freshwater aquaculture efficiency will promote the sustainable development of freshwater aquaculture, which is crucial to ensure aquatic food supply. In particular, measuring the total factor productivity (TFP) of freshwater aquaculture to find ways to improve its efficiency is of great significance to sustainable development of freshwater aquaculture industry. Therefore, ba ...

Abstract:
... To contribute to improving eel stocking procedures, the survival, growth and behaviour of farmed Japanese eels reared together with wild individuals were evaluated to learn about possible encounters of farmed‐ and stocked eels with wild eels. Two experiments were conducted to evaluate the (a) effect of the presence of wild eels on survival and growth of farmed eels in experimental ponds and (b) be ...

Abstract:
... Numerical simulation is an important method for calculating the hydrodynamic performance of otter boards used in sea floor trawling. Although such simulations have been explored in prior studies, the effects of the proximity of the otter boards to the seafloor and the plume of upward-drawn sediment during bottom trawling have largely been ignored. In this study, we assessed these factors. The resu ...
... Aquaculture is considered one of the world's fastest‐growing food production industries. It provides one of the most environmentally friendly sources of edible protein. The rapid expansion of aquaculture has occurred in response to a huge increase in world population and the corresponding demand for food, highlighting a path towards intensive sustainable products and resource efficiency. Improved ...

Abstract:
... This study explores the critical factors of pond aquaculture development in Nigeria, and opportunities and challenges for sustainable expansion of the sector. Aquaculture’s role in food security especially in developing countries has been recognized, including its growth potential. However, Nigeria’s aquaculture development remains slow. Using Delphi technique, key factors influencing aquaculture ...

Abstract:
... Aquaculture sustainable development is necessary since it is categorized as the most important source of aquatic products for human consumption and it is expected to keep growing shortly. For this reason, the addition of natural immunostimulants to fish diet to improve fish health and to preserve the environment have great importance in aquaculture. In this sense, new biotechnological tools as nat ...
