“…In fish, shrimp and seaweed cultivation activities, disease attacks are the main obstacles (Loch & Faisal, 2015;Mohamad et al, 2019;Dey et al, 2019;Ward et al, 2019). The results of this study indicate that the transmission of ice-ice disease to healthy seaweed thallus causes discoloration and weight loss.…”

al conocimiento de este grupo en la región. Métodos: Los muestreos se realizaron empleando diversas artes de pesca, en los principales ríos y tributarios que se encuentran en el municipio. Resultados: Se recolectaron 2,430 peces, correspondientes a 38 especies, agrupadas en 31 géneros, 19 familias y 12 órdenes. Las familias con la mayor riqueza específica fueron Cichlidae y Poeciliidae con nueve y seis especies. Priapella intermedia fue la especie más abundante (30.1% del total), seguida por Astyanax finitimus (13.3%) y Pseudoxiphophorus bimaculatus (10.3%). Con respecto a los aspectos biogeográficos del conjunto íctico, se observó un predominio de especies neotropicales (91.9%), dos especies de origen neártico (Ictalurus meridionalis e Ictiobus meridionalis) y cuatro vicarias (Atherinella sallei, Cathorops cf. kailolae, Eugerres mexicanus y Strongylura hubbsi), 31 especies se encuentran evaluadas en alguna categoría de riesgo y dos son exóticas. Conclusiones: La ictiofauna de Santa María Chimalapa es similar al de los cuerpos acuáticos presentes en selvas del sur de México. Son necesarios estudios ecológicos, de conservación e impacto antropogénico para establecer estrategias sustentables de conservación.

“…The purpose of this work is neither to discuss existing research on shrimp diseases in aquaculture through the lens of biologists [8,9] nor the effects of diseases over shrimp industry from an ecological perspective [10].By the time we wrote a literature review, there is very little research on the classification or detection of shrimp diseases based on images. YHV recognition application was designed in [11].…”

Vietnam is one of the top 5 largest shrimp exporters globally, and Mekong delta of Vietnam contributes more than 80% of total national production. Along with intensive farming and growing shrimp farming area, diseases are a severe threat to productivity and sustainable development. Timely response to emerging shrimp diseases is critical. Early detection and treatment practices could help mitigate disease outbreaks, leading to on-site diagnostics, instant services recommendation, and front-line treatments. The authors establish a contribution hub for data collection in the ethnographic fieldwork of Mekong delta. Several deep convolutional neural networks are trained by applying the transfer learning technique. We have investigated six common reported shrimp diseases. The classification accuracy is achieved of 90.02%, which is very useful in extremely non-standard images. Throughout the work, we raise the attention of shrimp experts, computer scientists, treatment agencies, and policymakers to develop preventive strategies against shrimp diseases.

“…Hence, it is necessary to develop a treatment against the virus. To date, following the concept of “trained immunity”, several kinds of WSSV immunizing agents have been tested, including viral protein subunits, attenuated WSSV, and DNA-/RNA-based agents 31 , 32 . Most recombinant subunit vaccines investigated have been based on VP19, VP24, VP26, VP28, VP292, and VP466, and among them, VP28 has been widely studied 33 – 37 .…”

White spot syndrome virus (WSSV) is one of the most devastating pathogens in penaeid shrimp and can cause massive damage in shrimp aquaculture industries. Previously, the WSSV structural protein VP15 was identified as an antigenic reagent against WSSV infections. In this study, we truncated this protein into VP15(1–25), VP15(26–57), VP15(58–80), and VP15(1–25,58–80). The purified proteins from the E. coli expression system were assayed as potential protective agents in Kuruma shrimp (Marsupenaeus japonicus) using the prime-and-boost strategy. Among the four truncated constructs, VP15(26–57) provided a significant improvement in the shrimp survival rate after 20 days of viral infection. Subsequently, four peptides (KR11, SR11, SK10, and KK13) from VP15(26–57) were synthesized and applied in an in vivo assay. Our results showed that SR11 could significantly enhance the shrimp survival rate, as determined from the accumulated survival rate. Moreover, a multiligand binding protein with a role in the host immune response and a possible VP15-binding partner, MjgC1qR, from the host M. japonicus were employed to test its binding with the VP15 protein. GST pull-down assays revealed that MjgC1qR binds with VP15, VP15(26–57), and SR11. Taken together, we conclude that SR11 is a determinant antigenic peptide of VP15 conferring antiviral activity against WSSV.
