Haematological and ion regulatory effects of nitrite in the air-breathing snakehead fish Channa striata

► Channa striata is tolerant to nitrite with a 96h LC50 of 4.7mM. ► Exposure to 3mM nitrite reduces total osmolality and sodium with 20%. ► Exposure to 3mM nitrite causes a 40% reduction in chloride. ► Despite exposure to 3mM nitrite, methaemoglobin levels does not exceed 40%. ► The effects observed...
