Carp liver, gallbladder, intestine and other diseases (picture)

Incidence: pond culture, chronic disease, thin water quality, normal food intake, feeding 30 protein feed (containing flavomycin) attachment: you need to log in to download or view the attachment. No account number? Registration-very good picture, thank you for providing, what do you think is the cause? Thank you for the picture. Is the water quality normal? What kind of solution are you? Could you be more specific about the situation? Such as the course of disease, the season of onset, the investigation of water quality, feed formula and drug use. Time: June 2008, 10 mu pond, water quality was thin (all indicators were normal), chlorine dioxide was used to disinfect water for 4 consecutive days, florfenicol and multivitamins were used in combination. Use it continuously for 5 days-these pictures are often seen during disease outbreaks in the course of breeding carp. I hope you can provide more similar pictures for learning in the future. Thank you-the way the landlord dissects the fish is a little unprofessional-ask this teacher, how should it be dissected? If it is convenient, please reply, you can also send it to my email: sdlipeng118@163.com, thank you-your anatomy is a little unprofessional, this kind of anatomy should make fish to eat. But the picture is good. This should be a kind of syndromes. Is it a bacterial disease? Disinfect water, improve immunity, and disinfect fish at the same time. That's a good idea. But is the medicine right? How effective is your plan? -- is there septicemia? Does it look like you have blue gills? I would like to ask you how to deal with it, how is the effect-in fact, the anatomy is quite professional, but the liver part does not seem to be very clear-thank you for your dedication, and learned a lot!
