The intestinal microbiota is involved in a wide range of biological processes that benefit the host, including providing nutrition and modulating the immune system. Fine flounder (Paralichthys adspersus) is a flatfish of commercial interest that is native to the Chilean coast. The high value of this flatfish has prompted the development of stock enhancement and aquaculture activities. Knowledge...

PURPOSE As capture fishery production has reached its limits and global demand for aquatic products is still increasing, aquaculture has become the world's fastest growing animal production sector. In attempts to evaluate the environmental consequences of this rapid expansion, life cycle assessment (LCA) has become a frequently used method. The present review of current peer-reviewed literature...

We write to extol the virtues of filterfeeding bivalve shellfish – clams, mussels, oysters and scallops – to give them their due as key players in ecologically sustainable aquaculture in the marine environment and as environmentally sensitive monitors and water purifiers. Shellfish are successfully farmed throughout the world and shellfish culture represents a legitimate use of the marine envir...

Since 1960s Community aquaculture gained its importance in India through the attempts of Research and Development agencies. Demonstration of fish culture practices in community ponds are challenged by its nature as water bodies are common property resources which requires substantial support from communities, local bodies and other agencies. Krishi Vigyan Kendra (KVK) Khordha, the Farm Science ...

Lipids are the predominant source of energy for fish. The mechanisms by which fish allocate energy from lipids, for metabolism, development, growth and reproduction are critical for understanding key life history strategies and transitions. Currently, the major lipid component in aquaculture diets is fish oil (FO), derived from wild capture fisheries that are exploited at their maximum sustaina...

Aquaculture is considered as a viable source for providing high quality and cheap protein, particularly for developing countries with protein shortages. However, due to its complexities, aquaculture development planning can be difficult without the aid of modern decisionmaking technologies such as decision support systems (DSS). DSS are widely used in the business and manufacturing sectors, but...

Automated water quality monitoring systems can be used to help maintain optimal levels of dissolved oxygen (DO) in aquaculture systems by continuously monitoring oxygen concentrations and immediately turning on aerators to supplement oxygen if a critical limit is reached. This study compares differences in water quality maintenance under operation schemes using manual and automated water qualit...
