Litopenaeus vannamei (pacific white shrimp) is the most cultured shrimp species which is also susceptible to microbial diseases like other shrimps. In the present study, the fungi, Aspergillus awamori KM434331 caused black gill disease to pacific white shrimp. It was first reported from L. vannamei in shrimp grow out pond located at Vellapallam, Nagapattinam District, Tamil Nadu, India. A. awamori KM434331 was isolated from affected gill of shrimp. Further, its morphological, cultural and phylogenetic characteristics were identified. The histopathological depiction is inflammatory response of L. vannamei against A. awamori KM434331 are haemocytic infiltration, encapsulation, melanization and collagen-like fibre deposition in the gill. In addition to that, Aspergillus awamori KM434331 cause dysfunction of gills that leads to chronic mortality in the grow-out pond of shrimps. (C) 2015 Elsevier B.V. All rights reserved.
