The potential applications of stabilized quality rice bran in aquaculture

Update: 3/22/2013

Stabilized rice bran is produced with strict technical rules to maintain and maximize nutritional values of products.

Fresh bran is first grinded, with no impurities and  low free fatty acid, and then taken into a heat process and compress to remove factors affecting quality such as lipase enzyme, mold ......
Bran is then oil extracted to bring out stabilized rice bran products with advantages of quality nutritional values: high protein, rich of vitamins and minerals, rich of natural antioxidants, especially storage time  up to 6 months, which overcomes the biggest drawback of fresh bran ( get rancid quickly).

Additional carbon source
Using too much food makes up a class of potential toxic mud. Nitrogen rate in ponds is usually high, especially in the end of harvest season,  when there is lack of carbon source for bacterials growth.

Adding enough carbon can help bacterials grow rapidly, cleaning the environment and they are also used as a additional food for fed objects. Therefore we can reduce feed costs.

It is considered a solution for sustainable development. Thus, farmers can use stabilized quality rice bran as a suitable carbon source added in the pond.
 
Materials in diets
With high protein rate, stabilized quality rice bran can be mixed in the diets from 35 to 39%, which can bring good results on the growth,  food utilization efficiency is high and transfer coefficients is low.
 
Stabilized quality rice bran is usually used as a popular ingredient in diets for catfish and tilapia.  A research of the Faculty of Fisheries, Can Tho University proved that stabilized quality rice bran can be mixed up to 60% in diets without affecting survival rate, growth speed and meat quality of farmed fish.
 
Direct food source for Artemia
Artemia have feeding habits that do not choose in an area range of particles smaller than 50 µm.  Farmers often mix manure (mainly from chicken) with inorganic fertilizers (Urea, DAP, etc.) to raise algae to feed directly Artemia.
