“…The LOD for Pm NV kits varies from <10 to 100 copies and the detection time varies from ~40 min to 4 h based on the methodology used in each kit. Several studies 51,113 used IQ2000 DPS kits (GeneReach) for pathogen identification. The kit has a detection limit of 10 copies/reaction and the time required from sample preparation to the final results is ~3 h. Other commercially available kits for Pm NV detection and their details are shown in Table S4.…”

Viral diseases are one of the constraints affecting the sustainability of the shrimp farming industry worldwide. The common causes of viral infections include white spot syndrome virus, infectious hypodermal and haematopoietic necrosis virus, hepatopancreatic parvovirus, Penaeus monodon nudivirus, decapod iridescent virus 1, Taura syndrome virus, yellow head virus, infectious myonecrosis virus and Macrobrachium rosenbergii nodavirus. Accurate diagnostic methods are necessary for preventing the spread of these transboundary diseases. Many molecular diagnostic methods for shrimp viral diseases have been developed and are currently in use, including conventional polymerase chain reaction (PCR), nested PCR, loop‐mediated isothermal amplification PCR, recombinase polymerase assay and real‐time PCR. Although the World Organization for Animal Health (founded as OIE) recommends several PCR methods for shrimp disease diagnosis, there has been a lack of efforts to comparatively evaluate the performance of the available methods, resulting in a significant knowledge gap. Therefore, in this review, we compare various PCR assays and commercial PCR‐based diagnostic kits that have been developed and/or published previously, and discuss pros and cons of each of these methods. Our objective of this review is to offer enhanced clarity and a comprehensive overview of molecular diagnostic methods for shrimp viral diseases. This endeavour would serve as an important resource for researchers engaged in relevant studies and professionals within the shrimp‐farming industry, providing valuable guidance and insights.

“…In recent years, viral contamination in hatchery brood shrimp and horizontal and/or vertical transmission of the virus to offspring is seriously affecting production. Therefore, some traditional shrimp hatcheries adopted specified pathogen-free (SPF) production methods (Chakrobortty et al, 2020). Altogether 77 hatcheries (44 prawn and 33 shrimp hatcheries) are reported to use PL but the total number of hatcheries has been reduced in recent years (Fig.…”

Fish seed are important for the growth of aquaculture in Bangladesh, but there are many challenges associated with supplying quality fish seed. This review evaluated the current level of production, issues and challenges that are affecting the production of fish seed in Bangladesh. The fish hatchery was found to be the major contributor in terms of fish seed production. Out of 671 metric tons of fish seed produced in 2020–2021, above 99% were from hatcheries. Freshwater finfish hatcheries have expanded over the last 30 yr, and are distributed throughout the country, but there is no commercial hatchery for coastal and marine water finfish species in the country. Shrimp and prawn hatcheries are concentrated in Cox's Bazar and the greater Jassore regions, respectively, while crab culture is entirely dependent on wild capture. Crablets are collected from nature, which has a devastating impact on biodiversity and wild stocks. The fish seed value chain is multidirectional and interlinked, and intermediaries dominate the supply chain. Disease outbreaks and indiscriminate use of chemicals are major concerns in fish seed production. Management strategies such as the introduction of certification, training programs, technology transfer, access to credit, and implementation of the law could improve the quality and productivity of fish seed in Bangladesh.

“…Sin embargo, hasta el momento, el nivel de resistencia a WSSV mostrado por stocks selectos de L. vannamei no ha sido absoluto (Huang et al, 2012;Trang et al, 2019). Por lo tanto, aun cuando se utilicen reproductores certificados como libres de virus para producción larvaria, cualquier fallo en las medidas de bioseguridad al interior de las UPL pueden derivar en contaminación viral susceptible de ser transmitida horizontal o verticalmente a la descendencia (Chakrobortty et al, 2020). Actualmente, una de las tecnologías más prometedoras para el manejo de enfermedades virales en la camaronicultura son los biofármacos basados en los mecanismos del ARN de interferencia (ARNi), que son parte de la inmunidad antiviral natural del camarón (Gong & Zhang, 2021).…”

The white spot syndrome virus (WSSV) is a constant threat for white shrimp (L. vannamei) aquaculture since it can cause major economic losses. One of the biotechnologies that have gained relevance to prevent WSSV infections are the bio-drugs based on RNA interference (RNAi) mechanisms, which can be initiated by the exogenous application of double-stranded RNA (dsRNA) that is administrated to shrimp for blocking the expression of some viral gene. In the present work, we made a small-scale evaluation of a bio-drug (Bfvt) constructed from a specific dsRNA against the viral gene associated to orf89 from WSSV, as prophylactic treatment in L. vannamei broodstock. The Bfvt was administrated intramuscularly to shrimp broodstock from two families (B and C) with natural resistance to WSSV, which were subsequently challenged with the virus through two ways of infection (intramuscular and per os). The results show that although both families presented a similar resistance to WSSV, the administration of Bfvt decreased the viral load and increased the survival of shrimp challenged with the virus, especially those that were intramuscularly infected. We conclude that the intramuscular administration of Bfvt is efficient and viable as strategy to prevent the WSSV infection in shrimp broodstock confined to maturation.
