The loach is a warm-water fish known for its strong adaptability to various environments. It typically resides in shallow waters such as ponds, ditches, lakes, and rice paddies where the water is still or flows slowly. These fish are mostly benthic, meaning they live on the bottom of the water body, and often dig into the mud. They can survive in acidic soils as well.
One of the most fascinating features of the loach is its ability to breathe through its skin and even its intestines. This unique form of respiration allows it to survive in low-oxygen conditions. The intestinal wall is thin and rich in blood vessels, enabling gas exchange. When oxygen levels in the water drop, the loach can surface to take in air, which is then processed in the intestine before being expelled through the anus. Compared to other farmed fish, the loach has a much higher tolerance for anoxia, making it a promising species for aquaculture.
Studies have shown that when dissolved oxygen levels fall to 0.46–0.48 mg/L, loaches begin to die. However, in pond farming, they often rise to the surface and release air when oxygen is scarce. Even with dissolved oxygen below 0.16 mg/L, they can still survive. The ideal water temperature for loach growth is between 25°C and 27°C, though they can tolerate temperatures ranging from 13°C to 30°C. If the temperature drops below 5°C–6°C or rises above 34°C–35°C, they will burrow into the mud, up to 10–30 cm deep, to enter a dormant state.
During dormancy, as long as the soil remains slightly moist, the loach can maintain life by keeping its skin damp. Another notable behavior is their tendency to escape. During spring and summer, if the pond walls are slightly damaged or there's rising water, loaches can escape overnight. Therefore, proper measures must be taken to prevent them from escaping, including secure fencing and anti-escape devices at the water inlet and outlet.
HGH Pen Injector
An HGH pen injector is a medical device used to administer human growth hormone (HGH) through injection. It is a small, portable device that resembles a pen, hence the name. The HGH pen injector is designed to make it easier and more convenient for patients to self-administer their medication.
The HGH pen injector works by using a small needle to inject the medication into the subcutaneous tissue just below the skin. The device is pre-filled with a specific amount of medication, which is determined by the patient's doctor based on their individual needs.
The HGH pen injector is typically used by individuals who have a deficiency in growth hormone, which can lead to a variety of health problems. HGH therapy can help to increase muscle mass, reduce body fat, and improve bone density, among other benefits.
Overall, the HGH pen injector is a safe and effective way to administer growth hormone therapy for those who need it. However, it is important to follow the instructions provided by your doctor and to use the device properly to ensure the best possible results and minimize any potential side effects.
