Shrimp Disease control - Aquatic Animal Disease Report
: White spot syndrome virus (WSSV)
: and (10-85 DOC)
: average to high, 100% in some cases within 10 d.
: lethargic or moribund shrimps aggregated at pond surface and edges, slow to erratic swimming behavior, overall body color often reddish, minute to large (0.5-2.0 mm diameter) white inclusions embedded in the cuticle;
: early harvest, strict isolation of infected ponds from movement, strengthened control of transportation, disinfection of infected ponds using Calcium hypochlorite (chlorine).
: Yellowhead virus (YHV)
: could reach 100% in 2-5 days after infection.
: Affected shrimps showed sudden increase in feeding activity and abnormal growth, then loss of appetite; aggregated near the pond surface or at the edge of the ponds followed by mortalities. Body is discolored, cephalothorax/hepatopancreas swollen and turned to color yellow or brown. Tissues of most organs (gills, hepatopancreas, gut epidermis) were necrotic with degenerated cell nuclei. Shrimps were most sucsceptible at the age of 20-70 DOC (no infection in shrimps under 15 DOC). Fastest transmission of the disease was observed in shrimps at 20-30 DOC when mortality could reach 100% over 2-5 days of infection.
: Disinfection and discharge of contaminated water; movement and transportation control.
: with Phage A3
: and (10-45 DOC)
: could reach 95% in intensive and semi-intensive farms;
: shrimps become lethargic with soft, darkened shells, mottling of the carapace. Pathology appears to be limited to hepatopancreas.
