Occurrence and Prevention Methods of Rice Field Eel Diseases
Rice field eels live year-round in water bodies with complex environmental factors and are frequently attacked by pathogens such as viruses, bacteria and parasites. During the rearing process, sudden changes in water temperature, insufficient dissolved oxygen, excessively high water acidity, and poor feeding management, such as insufficient feed, malnutrition, or feeding rotten and spoiled feed, and deterioration of water quality, disrupt their physiological state, weaken the eel body and lower their resistance, and in severe cases often cause mass death. Even if they do not die, it directly affects the growth and development of the rice field eels. In some cases, it is also due to excessive stocking density, or

Fish Head Rice
Take fresh monkfish heads and arrange them in a salted stack or place them in a vat (tank) with 5-7% salt. After about 15 hours, wash and brush them, drain the water, first blanch them in boiling water to make the muscles contract, then steam them in a steamer basket. After about 1 hour they are ready to come out of the pot (judged by how easily the flesh separates from the bone). After removing from the pot and cooling, pick the flesh off (the fish bones, after being sun-dried and crushed into fish bone meal, are used as feed). Tear larger pieces of flesh into small pieces by hand, spread them out on mats to sun-dry, and after drying they become fish head rice, which can be packaged in small plastic bags. The finished product is pale yellow in color, with uniformly sized pieces of flesh

Why should cattle and sheep not be fed rice water after giving birth?
A farmer fed rice water to a cow after it gave birth to a calf, which caused rumen acidosis in the cow. Fortunately, the veterinarian treated it in time, so no loss was caused. According to the veterinarian, livestock are weak after giving birth, and feeding a moderate amount of rice water can supplement nutrition, strengthen the bones and muscles, and help cattle and sheep produce more milk. However, this is not the case for ruminant livestock such as cattle and sheep; drinking rice water after giving birth can easily cause rumen acidosis. After cattle and sheep develop this disease, for milder cases, sodium bicarbonate (cattle 60-100 grams, sheep 15-30 grams) and ginger tincture (cattle 80-100 milliliters,

How to select brood rice field eels? Detailed selection methods and techniques
To select seedlings with high egg production, high fertilization rate and hatching rate, and good quality, you must choose rice field eels (Monopterus albus) of a certain age and body weight, with a strong constitution and no serious diseases or external injuries, as brood eels. In the non-breeding season, female and male eels are difficult to distinguish by appearance, so they are generally selected and retained by body length. When the body length of the rice field eel is 20 cm-35 cm, the vast majority are female eels, and when the body length is above 45 cm, most are male eels. Under normal circumstances, they can be selected and retained in a 3:1 ratio according to the above two body length groups.
