The effects of environmental changes, on non-target organisms may impact and bring consequences at the molecular level in marine organisms. There is a lack of data supporting the hypothesis according to which environmental stress modulates the immune system, leading to an increased susceptibility to infectious agents in shrimps. The present study was focused on changes occurring in cellular defense proteins in Litopenaeus vannamei infected by virus infection hypodermal and hematopoietic necrosis (IHHNV) and white spot syndrome (WSSV). Western blot analysis was used to evaluate expression of protein Hsp70, in gill tissue. Up-regulation levels were supported by immune detection analysis, suggesting that IHHNV and WSSV-shrimp infection promotes changes in the expression of these proteins.

Global warming has threatened all-rounded hierarchical biosphere by reconstructing eco-structure and bringing biodiversity variations. Pacific white shrimp, a successful model of worldwide utilizing marine ectothermic resources, is facing huge losses due to multiple diseases relevant to intestinal microbiota (IM) dysbiosis during temperature fluctuation. However, how warming mediates shrimp health remains poorly understood.

This work aimed to elucidate the deterioration mechanisms of shrimp surimi gels during refrigerated storage, and the regulatory mechanisms of epigallocatechin-3-gallate loaded cyclodextrin-based metal-organic framework (EGCG@CD-MOF) as a model antioxidant. Labele-free proteomics provided a quantitative analysis of the differential proteomic signatures of degraded proteins. Structural proteins, like myosin, paramyosin, titin, laminin, and α-actinin, along with calcium regulatory proteins, like calcineurin and sarcoplasmic calcium-binding protein were found to be highly susceptible to oxidative degradation during refrigeration.

Feeding frequency is crucial for the growth and development of white shrimp () at various life stages. Although higher feeding frequencies can enhance growth, manual feeding methods significantly increase labor costs. Automatic feeding systems offer a cost-effective and efficient alternative, yet their application in intensive shrimp culture remains under-researched.
