Book Description

Safeguard the success of aquaculture operations without expensive antibiotics!

Diseases are a major threat to the sustainability of the aquaculture industry. Because antibiotics have many drawbacks, increasing importance is being placed on understanding the mechanisms that make nutrition a key factor in host defense against pathogens. Nutrition and Fish Health is the first book to provide comprehensive information on nutrition as a means to improve fish health and defend against infection.

Nutrition and Fish Health offers state-of-the-art information on diseases affecting cold-water and warm-water fish, as well as marine shrimp. It comprehensively addresses such vital issues as:

  • nutrition and feeding management
  • immuno-stimulants
  • mycotoxins
  • fish immune system mechanisms
  • the use of vaccines
  • nutrition and environmental stress
Nutrition and Fish Health is a comprehensive guide to using nutrition to make your aquaculture operation a success. Proper fish nutrition can help you:
  • reduce the risk of disease
  • decrease the risk of environmental contamination associated with the use of antibiotics
  • increase production of good quality product
  • increase profits
Generously illustrated with graphs, charts, tables, and photographs, Nutrition and Fish Health is an essential guidebook for aquaculturists, fish producers, extension agents, aquaculture students, disease specialists, and feed formulators.
