White shrimp are harvested primarily in the fall.
White shrimp is a good candidate for aqua-culture because of its fast growth, adaptability to diverse salinities, and its large size.
White Shrimp are cultured in tanks or ponds of different sizes and at very different stocking densities, depending on the needs and resourcesof each farmer.

 Fish meal replacement with feather-enzymatic hydrolyzates co-extruded with soya-bean meal in practical diets for the ...
Research was reported that examined the potential use of commercial steam-processed feather meal and feathers enzymatically hydrolyzed for 60 or 120 minutes as substitutes for fish meal in diets of the Pacific white shrimp (Litopenaeus vannamei) juveniles.
The weight gains of the juvenile shrimp fed the hydrolyzed feathers and soybean meal diets did not differ from the shrimp fed the fish meal control diet.
The researchers concluded that white shrimp may be fed a practical diet containing 20% enzymatically-hydrolyzed feathers and soybean meal extruded in a 2:1 ratio without altering growth or feed conversion.

 Manual of Diagnostic Tests for Aquatic Animals - 2003
Shrimp showing these gross signs of acute TS typically have soft shells, an empty gut and are often in the late D stages of the molt cycle.
During the transition phase (which may be occurring while many shrimp in the affected populations are still in the acute phase and daily mortalities are high), fair to moderate numbers of shrimp in affected ponds show random, multifocal, irregularly shaped melanised cuticular lesions.
Shrimp in the chronic phase of TS display no gross signs of infection, and histologically the only sign of infection is the presence of prominent LOS, which are spherical accumulations of cells that lack the central vessel of normal lymphoid organ tubules (11, 16, 17).

A growth trial was conducted to examine the need for supplemental methionine and the relative nutritional ef?cacy of different methionine sources for Pacific white shrimp, L. vannamei, fed diets in which soybean meal completely replaced ?sh meal and reared under zero-water exchange conditions.
Samples of 30 shrimp in each tank were weighed after 2, 4, 6 and 8 weeks and the feed rate adjusted accordingly.
The orthogonal contrast indicated that the ?nal weight, growth rate, and feed ef?ciency of the shrimp fed the control diet were signi?cantly lower than that of shrimp fed the methionine supplemented diets.

There are many hundreds of shrimp disease specialists working with the shrimp farming industry today, and many of these received much of their training directly or indirectly from the APL, including many of the 1,019 who participated in APL courses and workshops.
The APL remains a leader in shrimp disease research and in the past 1-3 years APL identified, characterized and named two new diseases from penaeid shrimp, as well as demonstrating that TSV, a shrimp picorna-like virus, is not a zoonotic threat to humans as had been incorrectly reported to the CDC by another research group.
The APL also conducted the primary quarantine on stocks of Pacific white shrimp in Tucson, producing the founder populations of pathogen-free stock that were later propagated and distributed by the Oceanic Institute in Hawaii to domestic broodstock producers and eventually to commercial shrimp farmers throughout the world.

 Exotic shrimp’s resistance to diseases “exaggerated” : QC IMC
The supposedly disease-resistant qualities of the exotic Pacific white Shrimp (Peneaus vannamei) are “exaggerated” and that it is in fact susceptible to local shrimp viruses.
A non-government organization in the fishery sector that is monitoring the introduction of the Pacific White Shrimp (Peneaus vannamei) in the country said Wednesday that the supposedly disease-resistant qualities of the species are “exaggerated” and that it is in fact susceptible to local shrimp viruses.
Arsenio Tanchuling, executive director of Tambuyog Development Center, said that two local shrimp viruses infected the 1,100 vannamei broodstocks that were imported for the experimental trial conducted by the Bureau of Fisheries and Aquatic Resources (BFAR) in the first quarter of this year.

Scientists at OI and Ceatech breed specific-pathogen-free (SPF) shrimp, which are shrimp that have been tested throughout their life and found to be free from nine critical viral pathogens that are harmful to shrimp.
Ceatech employs an intensive shrimp farming technology that makes use of lined round ponds to grow shrimp, whereas the farm in Texas uses traditional, coastal earthen ponds and less intensive production rates.
The shrimp under evaluation were bred to perform well in super-intensive production systems, and the evaluation will determine how well suited they are for production under these two conditions.

The shrimp spend their juvenile through adult lives in a controlled environment, in water with salinity about 1/35th that of the ocean.
