The reason for the failure of adult breeding

First, the mode of cultivation and density problems. Judging from the current situation, larval rearing mainly adopts brooding ponds or adult ponds. From the perspective of production practice, whether the broodstock or adult fish ponds are housed in squid, excessive pond silt or excessive stocking density is the main reason for the failure of breeding.
Second, water quality management issues. Carp is a famous fish, like the clear environment, intolerance of hypoxia, the higher the dissolved oxygen content of the water body, and many brooding fish pond or adult fish pond silt up to about 50 cm, organic matter is rich, the water is more fat, and Poisoning in ponds often occurs during cultivation.
Third, failed to grade stocking in time. During adult culture, the differences in growth between individuals are relatively large due to uneven body composition and predation, and when the supply of feed is insufficient, they can easily lead to small and large mutual killings, thus affecting the survival rate of carp culture. Grading in time should be conducted in the breeding process.
Fourth, management is not in place. First, the unpalatable food seriously affects the growth and survival rate of the squid; second, there is no repeated flushing and no oxygen-increasing equipment, resulting in the pooling of pond fish.
Fifth, there are problems with medication. Raising squid in adult ponds is often affected by fertilization and medication, while squid is particularly sensitive to trichlorfon. Fish breeding ponds should pay special attention to medication problems.

 Injection Device

Syringes can also call Disposable Medical Supplies, Disposable Syringe With Needle and Plastic Needle Tube such as some scientific instruments in chromatography to inject through the rubber septum. Injecting gas into a blood vessel will cause an air embolism. The way to remove air from the syringe to avoid embolism is to turn the syringe upside down, tap it lightly, and squeeze out a little bit of fluid before injecting into the bloodstream.

In some cases where accuracy is not the primary concern of germs, such as quantitative chemical analysis, glass syringes are still used due to the small error of the glass syringe and the smooth movement of the push rod.

You can also inject some of the juices into meat with a syringe to improve taste and texture while cooking, or into pastries when baking. Syringes can also fill ink cartridges with ink.
