“How to Start a Shrimp Farm”
Comment Page 4

@Horm Siphanna, @horn siphanna.one of the ways to minimize  your costs in raising shrimps is to go back to the traditional method of raising shrimps where you will just stock 3-5 shrimps per square meters. aeration is not needed. feeding and other inputs are at minimum and labor is not that intensive. the harvest is not that big but it can generate income for sure.

@Subramani Mayilvannan, for technical assistance regarding shrimp farming in your area, you may coordinate C.P. Aquaculture (India) Private Limited in Chennai.

dear all, the key success factors for shrimp farming are 1.) fry or seed, 2.) feed, 3.) environment, and 4.) management. a quality fry/seed must be specific-pathogen-free, should have passed the PCR check for different viruses such as WSSV, TSV, IHHNV, etc., must be fast growing. likewise, the feeds, which is about 50-60% of your total production cost must have complete nutritional ingredients needed by the shrimps, palatable and with high stability, thus maintaining low feed conversion ratio but not compromising the growth. the environment shall focus on site selection (accessibility to the market, hatchery, water source), project design, facilities, etc. lastly, the management is the technical ability to manage the project.

intensive (80-150 pcs.sq.m density) P. vannamei farming in the philippines have approximate production cost (excluding depreciation) as: 1.) Feeds- 50%, 2. Power (Electricity & Diesel)- 20%, 3.) Fry/Seed- 10%, 4.) Admin/Labor- 15%, 5.) Miscellaneous/Others- 5%.

optimum water parameters for shrimp farm:

1. water pH: 7.5-8.5
2. dissolved oxygen: >4 ppm
3. alkalinity: 80-120 ppm
4. total ammonia nitrogen: max. 0.1 ppm
5. nitrite: max. 0.25 ppm
6. hydrogen sulfide: max. 0.02 ppm
7. vibrio count (yellow colony): max. 10(3) [read as: ten to the third or ten cube] cfu/ml
8. (green colony): max 10(2) [read as ten squared] cfu/ml
9. (luminescence bacteria: 0
10. water depth: >1 meter
11. transparency: 20-40% of water depth
12. plankton: FBG: not more than 10%; dinoflagellates not more than 5%
