Description
Jinmei Tang and four co-authors track how the gills of a prized freshwater fish remodel during a day without enough oxygen, in 2026 work. Topmouth culter is farmed widely in China yet is unusually sensitive to low oxygen. Fish were held in water with low dissolved oxygen for up to twenty-four hours, with gills and blood checked at set times. Early on, the gill sheets twisted and thickened. Later, the tissue widened its blood spaces and packed in more red cells, changes that help grab oxygen.
Blood sugar spiked early and then fell away, while fat-carrying proteins kept climbing, hinting at a fuel switch from sugar to fat. Defense enzyme activity rose steadily, and the genes behind it switched on early then faded late. The authors read the pattern as a staged defense: quick chemical shields first, structural remodeling next, with costs mounting as stress drags on.
