In the turtle and soft-shelled turtle culture pond, there are often red bugs swimming in the pool surface and corner, so that a layer of red bloom is formed on the water surface. The real name of the red worm is Cladocera, which is a species of zooplankton in the water. It consists of many planktonic fleas, with an average body length of about one millimeter. The normal body color of Cladocera is grayish white, and it turns red only when the water is anoxic, so red worms are mostly found in stinky gutters. When a large number of red insects are found in the turtle pond, it shows that the pond water has begun to deteriorate and tends to rot, so it should be adjusted as soon as possible. The reason for the redness of Cladocera in anoxic water is that there is a kind of invertebrate erythrin in the blood, and its content will increase significantly and turn red when the water is anoxic.

The food of Cladocera is mainly protozoa, rotifers and some macroalgae in the water, as well as bacteria, so when there are too many of them in the soft-shelled turtle water, they will swallow a large number of phytoplankton that can increase oxygen by photosynthesis. In life, however, it needs to consume a lot of dissolved oxygen, so the water in the pool will go bad. However, because Cladocera can also swallow a large number of bacteria at the same time, it can maintain a certain number until it can control pathogens and prevent turtle and turtle diseases. Through experimental research, it is better to control the number of Cladocera within 15000 per liter of water. If you exceed this number, you should get it out in time.

The cladocera is an excellent feed for turtles and fish, and can be added as fresh feed to turtles and turtles. Cladocera also contains fat and calcium necessary for the growth and development of fish and turtles. For example, the experiment shows that when the carp is completely fed with Cladocera, its metabolic intensity can be increased by 100%. The experimental study also found that in fish culture, if only one kind of fresh feed is fed, it will often make the fish grow poorly and suffer from various diseases at the same time. But feeding Cladocera is an exception, as is the case with turtles and soft-shelled turtles. When juvenile turtles and soft-shelled turtles are fed with mixed feed with a large proportion of Cladocera, the excretion is less and the water pollution is slow. However, the growth of turtles was faster than that of the control. Therefore, the red worm is a good feed for turtles and soft-shelled turtles, and the water body where we raise turtles is the best growing water body, so it propagates very fast. when its population number exceeds our required standard, it can be fished out and fed to turtles and turtles, which can not only effectively regulate the water body, but also save a lot of feed, so it is a good thing to kill two birds with one stone. When applying, first disinfect and wash the saltwater with 2% salt water, and then mix it into the feed with the proportion of 5% Murray 8% of the feed amount. If the quantity is large, it should be dried or dried and sealed and preserved step by step after the above treatment.
