AQUACULTURE
the fastest growing food producing
sector in the world for the past 30
years.
Global fish production - more than 30 %
between 2006-2011 or 47.3 million tons to
63.6 million
Shrimp farming - in the Asian countries
91% of the world food production.

Many fisheries have reached their maximum
sustainable exploitation.
Concerns about security and safety of food.
High demand for high quality, low calorie,
high protein aquatic products.
Minimum carbon dioxide emission.

PROBIOTICS- represent one of the most promising
alternatives to antimicrobials
developed in recent years

PROBIOTICS IN AQUACULTURE
- live microorganisms that have a beneficial
effect on the host by modifying the microbial
community associated with the host.
- ensure improved use of the feed or enhance its
nutritional value
- enhance the host response towards disease
- improve the quality of its ambient environment

A PROBIOTIC PRODUCT WAS DEVELOPED FOR
THE AQUACULTURE INDUSTRY. THIS
PROBIOTIC PRODUCT OFFERS ATTRACTIVE
WINDOWS OF OPPORTUNITIES TO REDUCE
THE IMPORTATION OF FEED ADDITIVES SUCH
AS ANTIBIOTICS. THE PROCESS TECHNOLOGY
IS CONTINUOUSLY IMPROVED FOR MORE
COMPETITIVE PRODUCTS THAT WILL MEET
THE DEMANDS OF CONTINUOUS GROWTH.
