BLACK SPERMATOPHORE DISEASE

Definition

Disease occurring in Penaeus vannamei, often causing abnormal spermatozoa, of great concern to hatcheries in Central and Latin America where it is extensively cultured. The disease, the origin of which is still unknown, expresses itself in a brownish-black discoloration of the sperm ampule, the spermatophore, and the vas deferens. Secondary infections may occur.
