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.
The impact of diseases led some Asian shrimp farming countries to develop biofloc and recirculation aquaculture system (RAS) production technologies. Treating incoming water for culture operations and wastewater treatment are biosecurity measures for disease prevention and control.
Shrimp aquafeeds – live, fresh or formulated – should not be an entry point of potential pathogens to the shrimp and/or to their culture systems.
Accurate PCR testing of shrimp seedstock assures shrimp farmers that their seedstock is clean of major diseases. Ring tests verify that labs conducting PCR testing are obtaining correct, reliable and reproducible results when testing for specific shrimp diseases.
Shrimp nursery systems offer an important opportunity to increase profits. Properly designed and operated nurseries are highly biosecure facilities to grow postlarvae at very high densities.
Silencing genes in white spot syndrome virus (WSSV) with critical roles in replication could provide a strong antiviral effect and thus reduce shrimp mortality. The authors therefore established a study to evaluate the antiviral efficacy of double-stranded (ds)RNA against non-structural
Loop mediated isothermal amplification (LAMP) is a highly specific technique that can amplify DNA in isothermal conditions. The kit can amplify the target gene of the pathogen using a single temperature and give results in one hour.
The authors recently performed a study to evaluate immunity to white spot syndrome virus and virulent Vibrio parahaemolyticus in shrimp treated with a new mineral extract additive in pelletized feeds.
