Abstract Crustacean aquaculture, dominated by shrimp, is a highly profitable food‐producing sector in the world. However, variety of biotic and abiotic stressors can have adverse effect on immune system shrimp making them susceptible to diseases. Although vertebrate‐like adaptive lacking an efficient innate renders protection against invading pathogens. The comprises two distinct but overlapping components, cellular humoral, these are regulated through several signal transduction pathways....
Temperature is one of the most prominent abiotic factors affecting ectotherms. Most fish species, as ectotherms, have extraordinary ability to deal with a wide range temperature changes. While molecular mechanism underlying adaptation has long been interest, it still largely unexplored fish. Understanding fundamental mechanisms conferring tolerance fluctuations topic increasing interest may continue rise result global climate change. Catfish natural habitat and possess great plasticity in...
Experimental studies were conducted by injecting or feeding white spot syndrome virus (WSSV) derived from infected shrimp, Penaeus monodon (Fabricius), collected the south‐east coast of India, to five species two freshwater prawns, four crabs and three lobsters. All examined susceptible virus. infections in shrimp had same clinical symptoms histopathological characteristics as naturally P. . A cumulative mortality 100% was observed within 5–7 days injected with WSSV 7–9 fed tissue. Two mud...
Abstract The phenomenon of slow growth in farmed shrimp was observed for the first time 1989 Penaeus vannamei as a clinical manifestation runt deformity syndrome caused by infectious hypodermal and hematopoietic necrosis virus. Subsequently, it recorded monodon during 2001–2002. Since then, condition described (MSGS) has been reported from many countries. Though not leading to mortality, retarded at pond level results significant economic losses. Several potential pathogens have identified...
Tilapia parvovirus (TiPV) has been associated with heavy mortalities in tilapia as a single infection or co-infection lake virus (TiLV). In this study, TiPV was detected farmed Nile tilapia, Oreochromis niloticus, from two geographical regions of India, Maharashtra and Uttar Pradesh. TiPV-specific polymerase chain reaction (PCR) reported earlier used the screening. collected showed characteristic clinical signs, along TiLV and/or Aeromonas spp. However, fish Pradesh were apparently healthy...
Background: Aquaculture, the fastest-growing food production sector worldwide, faces significant challenges due to disease outbreaks, particularly from bacterial pathogens such as Flavobacterium columnare. These cause severe economic losses, necessitating development of effective diagnostic tools and vaccines. Methods: This study aimed express chondroitin AC lyase gene F. columnare, a key virulence factor in prokaryotic expression vector. The was PCR-amplified, cloned into pET-32a vector...
A new disease with high mortalities has been occurring in summer scince 1998 different ages of carp Cyprinus carpio cultured Korea. The clinical signs the included erratic swimming moribund fish at water surface, respiratory distress, presence thick and foggy mucus covering body gills. Dermal ulcers were also noticed a few cases. Microbiological, parasitological virological investigations carried out on samples collected from various localities. Although bacteria protozoan parasite recovered...
