Which risk accelerates when ram ventilation effectiveness reduces while swimming in a fish adapted to hypoxic conditions?

💡 Explanation

When ram ventilation reduces, the efficiency of countercurrent gas exchange in the gills decreases because less oxygenated water flows against the blood. This leads to anaerobic respiration, increasing lactic acid production. Therefore, lactic acid accumulation accelerates, rather than changes in ion balance, glycogen stores, or gill movement which are linked to distinct metabolic pathways.
