Aquaculture is the fastest food producing system of world which has grown tremendously during the past few decades to meet the growing demand for aquatic food. Approximately, 25% of the animal protein requirement of the human throughout the world is from aquatic organisms. Over the years, dramaticchanges inaquaculture practices have lead tothe significant 18% increase in production per year.

Aquaculture has lagged far behind medical research in applying genetics improvement techniques. However last 25 year was favorable period for the development of aquaculture genomics. Nutritional science has long tradition for recommending specific diets to the farmed fishes for getting more production. Nutrigenomics is the application of high throughput genomics tool in nutritional research.

Biotic and Abiotic stressors and its diagnostic methods in fishes

Bio-monitoring is science for assessing the environmental condition which may be surrounding water or air by using biotic organism. Fish and its response are a good indicator of qualitative assessment and accumulation of chemicals in organism tissues as quantitative assessment. Most commonly used method is the Haematological technique to determine the sub-lethal effects of pollutants and it is a quick screening method as sudden changes in blood parameters due to environmental or physiological stressors.

The expansion of aquaculture industry is a good sign to fulfill the increasing demand of fish. This development also leads to degradation of the environment due to the excess use of feed and fertilizers in the aquaculture systems. An ecofriendly technique has been identified and defined as Bioremediation to overcome this vital problem. Bioremediation is the natural or managed biological degradation of environmental pollution.

Probiotics- a new frontier in aquaculture

The aquaculture has gathered momentum as an industry for over past few decades. The basic paradigm is increased production at almost any cost. This boom in the industry has resulted in social, economic and ecological damage. Outbreaks of viral, bacterial, protozoan and fungal infections experienced devastating economic losses worldwide in nineties of last century.
