Ciba Shrimp feed technology for commercialization

Background

Shrimp farming has shown phenomenal growth during the last decade in India. Feed being a major input, it has become a central focal point in shrimp farming. Shrimp feed market has shown impressive growth of more than 1,00,000 tons per annum during this period. There are more than six feed mills in the country, established with overseas collaboration and are producing shrimp feeds using imported raw materials. In the present situation of fluctuating shrimp prices in international and domestic market and also the feed cost going up farmers are looking to reduction in cost of feed. In this context Central Institute of Brackishwater Aquaculture (CIBA) has developed indigenous shrimp feed technology for processing and production of different grades (Starter, Grower and Finisher) of pellet feeds for the culture of tiger shrimp (Penaeus monodon) and Indian white shrimp (P. indicus). The feeds were tested in yard experiments and also in extensive field trials in grow-out ponds. The indigenous shrimp feed technology developed at this Institute would help in producing good quality and cost effective feeds for shrimp farming in the country.

Feed Formulation

feed11

The institute has developed balanced shrimp feed formulations for Starter, Grower and Finisher grade feeds separately for tiger shrimp and the white shrimp based on their dietary nutritional requirements. The feed formulations contain vitamin and mineral mixtures developed exclusively for this shrimp. Beside, the formulations also contain feed attractants and other feed additives required for faster growth of shrimp and producing good feed conversion ratio (FCR). The raw materials are selected from a list of 16 ingredients representing protein sources (animal & plant), lipids, carbohydrate sources, feed additives and binders. The feed formulations confirm to the nutrient levels required for tiger shrimp and white shrimp as given in the table below:

Processing and Production of Feed

feed31

The feed production technology developed by CIBA is based on the ring-die pellet mill, which is indigenously available. The feed production involves grinding of raw materials, mixing, steam conditioning, pelletization, post-pellet conditioning, drying, grading and packing. All the processing stages are standardized in a pilot-scale feed mill for the production of good quality feeds.The shrimp feed technology also includes standardized processing of feed pellets using three choice binders for producing pellets with good aqua-stability (retaining of pellet shape in water).Following are the specifications of different grade feeds produced:

Pre-starter - 0.2 mm

Starter-I - 0.5 mm

Starter-II - 1.0 mm

Grower - 1.8- 2.0 mm

Finisher - 2.3 – 2.5 mm

Test Result of CIBA Shrimp Feeds

CIBA shrimp feeds are evolved by three tier testing system. First the feeds were tested in laboratory and yard experiments on three different size groups (postlarvae PL-20, juveniles 2-5g and adults 10-15g) of tiger shrimp (Penaeus monodon) and Indian white shrimp (P.indicus). Using the successful formulations, large quantities of feeds were produced in pilotscale feed mill established at the Muttukadu experimental station of CIBA. These feeds were extensively tested in grow-out ponds of the institute and also ponds belonging to farmers in different locations. The feeds had produced excellent growth of shrimp and gave good FCR of 1.2 to 1.8: 1 The performance of the CIBA feeds tested on tiger shrimp in grow-out ponds is summarized in the table below:

Desirable Features of CIBA Shrimp Feed

CIBA shrimp feed is produced using indigenous machinery and also largely using indigenous raw materials. Because of this the cost of feed produced has an edge over the commercial imported feeds. Since shrimp production and FCR obtained with CIBA shrimp feed arepractically on par with those of the commercial feeds, the cost of production of shrimp with CIBA feed is lower than that of the latter. Hence the farmer realizes better profits by use of CIBA shrimp feed which is a very desirable feature. There fore there is an excellent market potential for this shrimp feed. Presently shrimp aquaculture is carried out only in about 15% of the coastal lands available for this purpose. The area under shrimp farming is rapidly expanding opening up large demand for shrimp feed. Hence there is good potential for shrimp feed market.

Cost of Feed Production Unit

The feed production unit can be established at an approximate cost of rupees 50 lakhs with aproduction capacity of 2 tons of feed per hour with single pellet mill unit. Having multiple units of pellet mill can increase the total feed production capacity.

Transfer of Technology

The CIBA shrimp feed technology can be transferred to prospective ntrepreneurs by the institute. For details please contact the following address
