What causes a kerosene smell in fish?
If the water used for raising fish is contaminated with phenol (the wastewater discharged by some metallurgy, coal gas, petroleum, chemical and other enterprises contains phenol). When the concentration of phenol in the water reaches a certain level, the fish naturally develop a kerosene smell. Fish contaminated with phenol are toxic and harmful to the human body. If eaten accidentally and the amount of phenol ingested exceeds a certain limit, it can cause poisoning in people, and even death.
