Friends who raise Pelteobagrus fulvidraco, have you ever encountered a situation where the fish suddenly stopped eating? I was having a great time eating just a few days ago. Why did I suddenly go on a hunger strike? Don't worry. Today, we'll delve into the common reasons why pelteobagrus fulvidraco doesn't eat food and the solutions!
1. Deterioration of water quality
Pelteobagrus fulvidraco has high requirements for water quality. If the water body has the following problems, it will lead to a decrease in the fish's appetite:
Excessive ammonia nitrogen and nitrite: They affect the metabolism of fish and cause them to refuse to eat.
Abnormal pH value (too high or too low) : Affects the physiological functions of fish.
Insufficient dissolved oxygen: Pelteobagrus fulvidraco prefers a high-dissolved oxygen environment. When the dissolved oxygen level drops below 3mg/L, its food intake significantly decreases.
Solution
Regularly test the water quality and use oxygenators or oxygenators to increase dissolved oxygen.
2. Sudden changes in weather
Pelteobagrus fulvidraco is sensitive to temperature changes, especially:
Continuous rainy weather: Low air pressure, decreased dissolved oxygen, and fish body stress.
A large temperature difference (such as a sudden drop in temperature) : It causes the fish's metabolism to slow down and their appetite to decrease.
Solution
Pay attention to the weather forecast in advance and reduce the feeding amount before the weather changes.
Use anti-stress products (such as VC and glucose) to enhance the fish's resistance.
3. Impact of diseases
If pelteobagrus fulvidraco is infected with enteritis, parasites or bacteria, it will also show a loss of appetite. Common symptoms:
Enteritis: Redness and swelling of the anus, abnormal stool.
Parasites (such as trichozoan and ringworm) : The fish turns black, rubs against the pool, the gill filaments swell, and secretes a large amount of mucus.
Bacterial infections (such as gill rot and hemorrhagic disease) : The body surface is congested and the gill filaments are rotten.
Solution
Observe whether there are any abnormalities in the fish body and conduct microscopic examination or send it for examination in a timely manner. Targeted medication
Enteritis: Mix the feed and administer enrofloxacin + allicin.
Parasites: After microscopic examination and confirmation, for the protozoa carroworm, copper sulfate is selected for killing. For intestinal tapeworms, praziquantel drugs can be mixed with feed and taken internally for deworming.
Bacterial diseases: Disinfect with chlorine dioxide or iodine preparations.
4. Feed issues
Moldy feed: Pelteobagrus fulvidraco has a sensitive sense of smell and will refuse to eat moldy feed.
Poor palatability: Inappropriate particle size or insufficient appetite stimulant.
Sudden feed change: Insufficient transition, causing the fish to be unable to adapt.
Solution
Check if the feed is fresh and pay attention to moisture-proofing when storing.
Choose special ingredients that are high in protein and have a strong fishy aroma.
When changing materials, adopt the "3-day transition method" (70% old material + 30% new material → gradually adjust).
5. Environmental stress
Frequent net pulling and pool changing: This can startle the fish, causing them to stop feeding for a short period of time.
Strong light or noise: Pelteobagrus fulvidraco prefers a dark environment. Strong light will cause it to hide and not eat food.
Solution
Reduce human interference and maintain a stable breeding environment; The pond can be shaded appropriately.
