Black Tiger Shrimp Market ? Market Growth & Development is not possible if this trend Continues in Shrimp Aquaculture Industry.

Monodon prices - why lower than vannamei? • Not true in all markets, • Consumers trading down from monodon to vannamei? • Monodon no longer marketed as much as before?

Technical/Business Reasons ? 1. Fluctuation of Brood Stock Supply 2. Poor Quality Brood Stock due to probable inbreeding. 3. Post larvae Produced will be lower in Quality. 4. More Disease Occurrence in the Farms 5. Low Productivity 6. High Production Cost 7. Inconsistent Supply to Export market 8. Fluctuation in Shrimp Prices 9. Under productivity from the Existing Ponds 10. Loss of Business Opportunities

What is the Solution? Switch to Vannamei Shrimp farming. Is it Correct? Are we in the right path?

Introduction Penaeus vannamei also known as the pacific white or whiteleg shrimp is native to the Pacific coast of Mexico southward to Peru. Whiteleg shrimps occur in tropical marine areas with water temperatures normally higher than 20ºC throughout the year. They are highly euryhaline and can withstand salinities ranging from 0 to 55 ppt. Adults live and spawn in the open ocean whereas postlarvae migrate inshore to spend their juvenile, adolescent and sub-adult stages in coastal estuaries, lagoons or mangrove areas.

Taxonomic Classification Kingdom: Animalia Phylum: Anthropoda Subphylum: Crustacea Class: Malacostraca Subclass: Eumalacostraca Order: Decapoda Suborder: Dendrobranchiata Superfamily: Penaeidae Family: Penaeidae Genus: Penaeus Species: Vannamei

Biological Features Rostrum moderately long with 7 -10 dorsal and 2 -4 ventral teeth. In mature males petasma symmetrical and semiopen. Spermatophores complex, consisting of sperm mass encapsulated by sheath. Mature female has open thelycum. Maximum size 23 cm, with maximum CL of 9 cm.

Biology Males become mature from 20 g and females from 28 g onwards at the age of 6 -7 months P. vannamei weighing 30 -45 g will spawn 100250, 000 eggs of approximately 0. 22 mm in diameter. Hatching occurs about 16 hrs after spawning and fertilization.

Site Selection Topography and Climate Condition -Topographically, the best areas for shrimp culture are those with average natural ground elevations of about 1 -3 m above mean sea level or at least 1 m above the highest high tide level to allow drainage and harvesting. -The sites should have minimum vegetative cover, be near the sea or other natural waterways such as rivers and streams, have easy access to roads, a sparse population and be nearly square or rectangular in shape.

-In terms of climatic conditions, areas having short and not as pronounced a dry season with moderate rainfall distributed throughout the year are the best suited for shrimp farming. A pronounced long dry season may cause an increase in water temperature and salinity, which will promote excessive growth of algae and result in oxygen depletion at night.

Infrastructure Accessibility -The farm must have good accessibility either by road or water, and communication systems throughout the year in order to facilitate supervision and transport of materials and products. - It is important that the farm be within 3 -6 hrs traveling time from the hatchery to avoid excessively long transportation time of the larvae and should be within 10 hrs from the processing plant to avoid deterioration of the product

Electricity -Availability of relatively cheap and reliable power source is a major consideration in site selection. In areas where electricity supply exists, it is practical and beneficial to utilize electric power to run the farm, especially for the intensive culture system. It is advisable to have a back-up electricity generator as a secondary power source.

Security -Areas free from security risks result in favorable working conditions, productivity and less extra costs. Availability of Labor and Other Factor -The availability of labor, equipment and commercial feed and supplies ensure smooth operations and successful crop.

Water Supply -Site should have good pollution free water supply of both freshwater and brackish water. Soil Conditions - The type of soil is the most critical in site selection, since the shrimp will spend most of their time on the pond bottom during the culture period. Usually, clay or loam-based soil containing more than 90% clay and p. H between 6. 5 -8. 5 is preferable.

Special Features of Vannamei Shrimp Farming Growth Rate Stocking Density Salinity Tolerance Temperature Tolerance Dietary Protein Requirements Ease of Breeding and Domestication Larval Rearing Disease Resistance Post Harvest Characteristics

Growth Rate P. vannamei can grow as fast as P. monodon up to 20 g and typically grows faster (1 -1. 5 g/wk) than P. monodon (1 g/wk) currently in Asia. Size range on harvest generally smaller.

Stocking Density Penaeus vannamei are amenable to culture at very high stocking densities of up to 150/m 2 in pond culture, and even as high as 400/m 2 in controlled recirculated tank culture. Although such intensive culture systems require a much higher degree of control over environmental parameters, it enables the production of high numbers of shrimp in limited areas, resulting in better productivity per unit area than that currently achievable with P. monodon in Asia.

Salinity Tolerance Penaeus vannamei tolerates a wide range of salinities, from 0. 5 -45 ppt, is comfortable at 7 -34 ppt, but grows particularly well at low salinities of around 10 -15 ppt (where the environment and the blood are isosmotic).

Temperature Tolerance P. vannamei will tolerate a wide range of temperatures, but it grows best between 23 -30ºC. They will also tolerate temperatures down to 15ºC and up to 33ºC without problems. Penaeus vannamei can thus be profitably cultured during the cool season in Asia (October-February). This is traditionally the low season for P. monodon farmers in this part of the world, meaning that increased yearly harvests may be possible using these alien species. This greater temperature tolerance of P. vannamei may also be a reason why farmers have perceived this species to be more resistant to WSSV relative to P. monodon. However, recent experience in Thailand, Ecuador and elsewhere has shown that when water temperatures decline to less than 30ºC, increased problems with viral diseases such as WSSV and TSV occur not just with P. monodon, but equally with P. vannamei.

DIETARY PROTIEN REQUIREMENT P. vannamei requires a lower protein (and hence cheaper) diet (20 -35 percent) during culture than P. monodon, and are more able to utilize the natural productivity of shrimp ponds, even under intensive culture conditions. In Thailand for example, current grow-out feeds for P. vannamei contain 35 percent protein and cost 10 -15 percent less than the 4042 percent protein feeds for P. monodon. Additionally, feeding efficiency is better with P. vannamei, which yield an average FCR of 1. 2, compared to 1. 6 for P. monodon. These factors, together with higher growth and survival rates are responsible for the 25 -30 percent lower production costs for producing 20 g of P. vannamei than P. monodon.

Ease of Breeding & Domestication P. vannamei is an open thelycum species, meaning that they can be induced to mate and spawn easily in captivity (unlike the closed thelycum P. monodon) which enables the culturist to close the life cycle of the shrimp, facilitating genetic selection (i. e. for improved growth rate and disease resistance) and domestication programmes. This feature permits much more control and enhancement of the cultured stock and allows the development of SPF and SPR stocks, which are already commercially available. This in turn relieves the expense, disease implications, environmental concerns, unpredictability and waste of relying on wild broodstock

Larval Rearing Larval survival rates during hatchery rearing are generally higher (60 -70 percent) with P. vannamei than with P. monodon (40 -50 percent)

Disease Resistance Penaeus vannamei is generally considered to be more disease resistant than other white shrimp. Penaeus monodon is generally regarded as being highly susceptible to both WSSV and YHV, but not to IHHNV or TSV.

Post Harvest Charesteristics After harvest, if well treated with plenty of ice, P. vannamei are particularly resistant to melanosis and keep a good appearance three to four days after defrosting. However, P. monodon tend to have a longer shelf life and are easier to handle, transport and process than P. vannamei.
