The Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) is established in shrimp ponds in Ecuador. Current PCR protocols are insufficient. 

Según los autores, la relación virus-huésped, donde los genotipos circulantes de IHHNV coexisten con el camarón blanco del Pacífico cultivado, está potencialmente evolucionando. 

The virus-host relationship, where circulating genotypes of IHHNV co-exist with farmed Pacific white shrimp, is potentially evolving, authors find. 

Este estudio simuló el crecimiento comercial de dos cohortes de P. monodon que diferían en las cargas de infección por IHHNV de sus reproductores, y mostró que la prevalencia viral, la supervivencia y el rendimiento de crecimiento de la progenie en estanques se vieron significativamente afectados. 

This study simulated the commercial grow-out of two cohorts of P. monodon that differed in their broodstock IHHNV infection loads, and showed that the viral prevalence, survival and growth performance of pond progeny were significantly affected. 

Indian shrimp hatcheries have experienced larval mortality in the zoea-2 stage, with molt deterioration and resulting in heavy mortality. Authors considered biotic and abiotic factors. Part 2 describes results of their study. 

Indian shrimp hatcheries have experienced larval mortality in the zoea-2 stage, with molt deterioration and resulting in heavy mortality. Authors investigated the problem holistically. 

Los alimentos acuícolas para camarón – vivos, frescos o formulados – no deben ser un punto de entrada de patógenos potenciales para el camarón y/o sus sistemas de cultivo. 

Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems. 

A new breeding program for genetic improvement of Indian white shrimp (Fenneropenaeus indicus) in Egypt was established at a private shrimp farm at AL Dibah Triangle Zone (DTZ) to develop disease-resistant shrimp for the country’s aquaculture industry. 

This study evaluated the susceptibility to IHHNV in three different shrimp batches by measuring infectivity titers. Each batch showed a different infectivity titer, therefore, each batch had a specific susceptibility to IHHNV. 

Polymerase chain reaction (PCR) testing demonstrated that Penaeus monodon offspring derived from founder shrimp collected from the Indo-Pacific region had genomic infectious hypodermal and hematopoietic necrosis-related DNA sequences that reacted with OIE-listed IHHN virus diagnostic primers. 

The Queiroz Galvão Alimentos shrimp farm and hatchery in Brazil have been working with Concepto Azul to implement a disease-prevention and genetic-breeding program that addresses ongoing impacts from infectious myonecrosis virus (IMNV) and other pathogens. 

The authors conducted a study to investigate the prevalence of IHHNV in P. vannamei within the context of a family-based genetic selection program. 

Infectious Hypodermal and Hematopoietic Necrosis Virus (IHHNV) has been detected in farmed shrimp stocks around the world.
