Two wonderful ways to domesticate fish on stage quickly
In recent years, with the continuous development of @ # @ 233 feed technology, the method of raising fish with full-price pellet feed has been gradually popularized and applied. However, because many fish farmers are unable to feed and domesticate, the domesticated fish do not know how to come to the stage, which not only affects the feeding and growth, but also increases the cost and affects the feeding efficiency. Below, we will sum up in the production practice of two simple and easy successful domestication methods to the majority of users for reference.
First, the feed hanging bag domestication method uses the big-eye window screen (with no leakage) to make a hanging bag which can hold 1.5 to 2 kilograms of feed, then fill it with full-price pellet feed, hang the hanging bag in front of the bait table, make it float and expand, and let the fish peck freely. At the same time, sprinkle a small amount of the same feed slowly near the bag, so that the fish can be domesticated at a fixed time and at a fixed point, so that the fish can gather on the stage to grab food after about 2-3 days, and then scatter the hanging bag.
Second, light trapping and domestication method this method is to make use of the tendency of fish to light, at the beginning of domestication, install a 60W or 100W incandescent light bulb (preferably with a waterproof cover), hang in front of the bait table at night, about 0.7 meters from the water, and so on when fish are found swimming, a few grains of full-price feed are sprinkled into the water, so that they are gradually attracted into groups. Domesticated 2-3 times a day, gradually transferred to the day, a few days later, the fish can be clustered to the stage for food. Then cancel the lighting.

According to the source of parent eel, the wound caught in cage on the same day was smaller. Monopterus Albus has the characteristics of sexual transformation. Monopterus Albus is basically female at the age of 1 and 2, the proportion of males increases gradually after spawning at the age of 2, and is basically male at the age of 6. In the non-spawning season, it is difficult to distinguish between male and female, generally based on body length and weight, with a body length of 37cm to 50cm and a body weight of 7.
