Review Article Received: September 26, 2018; Published: November 19, 2018 Keywords: Nutritional Diseases; Aquaculture; Management This review was conducted to investigate the significance, underlying causes and negative effects of nutritional diseases of fish on aquaculture production and health safety. Information were collected from different secondary sources and then arranged chrono- logically. Investigation reveals that, Aquaculture is the largest single animal food producing agricultural sector that is growing rapidly all over the world. Nutritional disease is one of most devastating threats to aquaculture production because it is very difficult to identify nutritional diseases. Production cost get increased due to investment lost, fish mortality, treatment cost and decreased yield quality and quantity. Public health hazards are also in dangerous situation due to frequent disease outbreak and treatment involving synthetic drugs. It is very essential to control nutritional diseases to increase fish supply through aquaculture production. This study will be helpful to provide basic knowledge on nutritional diseases management in aquaculture and to raise awareness among the farmers fisheries management.

Introduction Aquaculture is currently the most growing agricultural sector in the world. Tremendous development have occurred in aquacul- ture during the last decades. Aquaculture production has shifted from extensive to semi-intensive and intensive culture systems [1,3]. Disease is an important constraint to aquaculture develop- ment and sustainability because production cost increases through investment loss as a result of fish mortality, cost of disease treat- ment and loss of product quality and quantity [4,5]. Due to frequent disease outbreak, public health and environmental safety are also threatened because human health hazards are related to disease occurrence and drugs resistance [1,2]. This sector is facing more challenges to make sure its sustainable development due to the emerging of new disease. Disease is a disturbed condition of liv- ing organisms in which normal physiological function of different parts of the body get changed expressing distinguished signs and symptoms. Development of an active fish disease is directly associ- ated to the effect of different pathogenic microorganism and also with the nutritional value of fish feed [1]. Fish diseases commonly outbreaks when fish are stressed due to a variety of physical, chem- ical and biological factors including poor nutrition [7]. Nutritional diseases are those which the results in due to excess nutrient or nutritional deficiency in fish than the normal require- ments. Lipids, carbohydrate, proteins vitamins and mineral salts are some of the important nutrient for proper fish growth [1]. The disease symptom disappears when the existing feed is changed with a new one [4].
