Multiomics profiling reveals the adaptive responses of largemouth bass to high temperature stress.

ABSTRACT:

Background

Largemouth bass (Micropterus salmoides) is among the most economically important freshwater fish species. High temperature is a major abiotic stressor, leading to increased mortality and significant economic losses. However, research on the regulatory mechanisms of heat stress response in largemouth bass is limited. This study aims to elucidate the mechanisms of adaptability in largemouth bass during heat stress and subsequent recovery.

Results

The morphobiochemical alterations and adaptive mechanisms induced by high water temperature in the gill, brain and liver tissues of largemouth bass are investigated through biochemical blood analysis, haematoxylin and eosin staining, transmission electron microscopy and transcriptomic and proteomic profiles. The results rev
