In turtle aquaculture ponds, red bugs often appear swimming on the pool surface and pool corners to form a layer of red blooms. The red worm - the real name is Cladocera, is a species of zooplankton in the water body. It is made up of many planktonic maggots, with an average length of about one millimeter. The normal body color of Cladocera is grayish, but it is red when the water is deprived of oxygen, so red bugs are found in stinking ditch. When a large number of red worms are found in the turtle pond, it shows that the pool water has started to deteriorate, and the trend toward corruption should be quickly adjusted. The cause of redness of Cladocera in anoxic waters is that blood contains a non-spinal red trout, and when the water is deprived of oxygen, its content will increase significantly and become red.
Cladocera foods are mainly protozoa in the water, rotifers, and some macroalgae. Of course, they also include bacteria. Therefore, when there are too many fish in the rearing water, they will ingest large amounts of planktonic algae capable of photosynthesis and oxygenation. In life, however, it needs to consume a lot of dissolved oxygen, so the pool water will get worse. However, because cladoceras can also ingest large amounts of bacteria, it is also possible to maintain a certain amount until the control of pathogens and prevent the effects of turtle disease. Through experimental studies, it is better to control the number of chandeliers within 15,000 liters of water. If you exceed this amount, you should fish it out in time.
The larvae that are removed are excellent feed for turtles and fish and can be added as fresh feed to turtle feed. The reason why Cladocera is a good feed is because Cladocera is rich in protein, which not only contains all the amino acids required by various fish species, but also has the highest content of essential amino acids, which is unmatched by other feeds. . Cladocera also contains fat and calcium essential for the growth and development of fish and turtles. Experiments have shown that when the squid is fed with horns completely, its metabolic intensity can be increased by 100%. The experimental study also found that when feeding fish, feeding only one kind of fresh feed will often result in poor growth of fish. Suffering from various diseases, except for the feeding of horns, the same is true for feeding turtles. When hatchlings feed only a large amount of mixed feed, the amount of excreted manure is small, and water pollution is slow. The turtle's growth was faster than the control. Therefore, the red worm is a good feed for turtles. The water we breed is the best growing body for the horned horns, so it breeds very quickly. When its population exceeds the standard we require, remove it and feed it. Hey, not only can effectively regulate the water body, make the water body transform in a good direction, but also can save a lot of feed, so it is a good thing that kills two birds with one stone. When applied, first remove the washed horns with 2% saline and wash them, then feed them in the feed at a rate of 5%-8%. If the quantity is large, it should be gradually added after being dried or sealed by drying after the above treatment.
