How to prevent and treat linear hepatic hemorrhage disease in farmed pufferfish
[Symptoms of linear hepatic hemorrhage disease in pufferfish] Sick pufferfish have a darkened body color, with the color from in front of the eyes to the snout noticeably paler; sometimes the body color of the pufferfish becomes pale while the area in front of the eyes becomes even paler and pallid.

When the abdomen of the fish is cut open, 1-2 obvious linear blood stasis marks can be seen on the liver, all extending upward from the left side of the abdomen to the right side. There is no food in the intestine, and the intestinal wall is sometimes slightly congested; sometimes severely affected fish show unusually frantic, random darting behavior, similar to the symptoms of white mouth disease in pufferfish. Linear hepatic hemorrhage disease in pufferfish has a high mortality rate, and there is currently no effective treatment method, so we adopt the policy of giving priority to prevention with treatment as a supplement.
