The star spot is not resistant to low temperature, and after entering December every year, the eastern star spot is prone to enteritis, rotten body, and a large amount of liver loss due to low temperature. The following is my visit to many large eastern star grouper farms in Hainan to summarize the experience of low temperature management, I hope it will help you.
Industrial cultivation of eastern star grouper.
Eastern star spot. The anti-stress ability of this fish is relatively poor, and the water quality requirements are relatively high, the normal water temperature is 28-30 degrees, the salinity is 18-20 grids, and the water flow rate is 30cm hours.
The eastern star spotted feeding is more ferocious, it is easy to overfeed, once it is overfed, it is easy to rot, climb the bottom, and liver damage. So it's important to feed properly: (FYI):
In addition, it can also be combined with fish feces, and the feces can be reduced or stopped when the feces are bad.
Normal stool: The stool is mostly formed and brown in color.
The manure is basically formed, but it is the color of the feed and the conversion rate is low.
The stool is granular, with more white and yellow stools.
The stool is not formed and loose.
Finally, the eastern star grouper must choose a good hepatoprotective product
The liver of the fish often turns yellow, and the antibacterial and insecticide drugs are more common for the eastern grouper, so the liver of the fish is easily damaged.
Longchang bile acid is an endogenous hepatoprotective product, he protects the liver more directly, and at the same time, he can also promote the elimination of liver toxins through the bile ducts, and repair the liver faster, so the eastern star group liver protection choiceLongchang bile acid
