This document presents a study on nutrition deficiency diseases in fish conducted by Akash Pradip Dash for their M.Sc. in Zoology. The objective of the study was to identify the causes of disease in fish to enable appropriate treatment and control. Common signs of malnutrition in fish include skeletal disorders, eye conditions, and generalized symptoms. Specific examples of nutritional deficiencies examined in the study include thiamine deficiency, nutritional myopathy, and ascorbic acid deficiency in the fish species Cromileptes altivelis. References cited include literature on nutritional diseases of fish in aquaculture and their management.

Nutrition Deficiency Disease In Fish

2. OBJECTIVE:
The continued expansion and improvements efficiency of aqua-cultural production
requires continued improvements in nutritional formulation and feed technology.
However, to be effective feed developments must consider on the one hand the
nutritional requirements of the cultured species, in terms of their energy, protein,
lipid, vitamin and mineral requirements and on the other hand the range of available
feed ingredients, their cost, digestibility and the nature and regularity of their
supplies
A quick and effective system is required to identify the cause of disease for
appropriate treatment and control of fish disease.
If possible, diseases specialist should ask the farm owners to provide information
signs and symptoms of affected fishes
Infectious pathogen is another underlying cause of many clinical signs and
symptoms.
Skeletal disorders, ophthalmologic conditions and generalized conditions are the
most common signs of malnutrition in fish.
