Fish diseases in fish cages in sea cages often occur in the summer and autumn and autumn and winter exchange seasons. The most important pathogenic factor is changes in the physical and chemical factors of seawater caused by weather changes. Therefore, special attention should be paid to the prevention of fish diseases in the season of alternating seasons. Prevention of fish diseases in cage culture of marine fish should focus on prevention, and do a good job of prevention work. When fish diseases occur, they must be isolated and treated in time. The main measures are: 1. Grasp the proper stocking density. 2. Strictly pay attention to the selection of robust and non-destructive seedlings. 3. In the culture process, freshwater baths are regularly given to farmed fish to reduce the occurrence of fish diseases. 4. Before the onset of winter, it is best to sterilize the fish in a light bath to increase resistance to disease. 5. Observe the feeding and activities of farmed fish. If any abnormalities are found, measures should be taken to deal with the situation. 6. In accordance with the principle of feeding, quality, timing, quantitative feeding, never fed fresh and deteriorated feed, can not blindly speed up or reduce the amount of feeding. 7. Pay attention to improving the aquaculture water environment to ensure smooth water circulation, remove any attachments attached to the cage in time, wash the net wall and float regularly, and replace the net clothes. 8. Replace cages in time, usually from fingerlings to adult fish. Replace cages 3 to 4 times. When replacing cages, be careful not to damage the fish. When the weather is bad in winter, avoid changing the cage. Despite its benefits, early enteral nutrition (EN) is considered controversial in critically ill patients with severe hemodynamic failure. Objective: To evaluate the tolerance and safety of early EN in a consecutive group of patients receiving venoarterial (VA) extracorporeal membrane oxygenation (ECMO) for severe hemodynamic failure. Materials and Methods: Prospective observational study performed in a cardiac surgical intensive care unit (ICU) during a 1â€year period. All adult patients receiving VA ECMO for severe hemodynamic failure unresponsive to conventional therapies were included. Nutrition support was provided during the study period following the established ICU nutrition protocol. Energy target was 25 kcal/kg, to be reached over 4 days. Nutrition tolerance was defined as the ratio of delivered nutrition to target nutrition, expressed as a percentage.
