Automatic Massage Foot Bath Machine
The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.

First, timely pooling. In order to grasp the growth and development of the broodstock and facilitate the deployment of oxytocin, the broodstock should be pooled when the water temperature is around 11°C, and the broodstock that is cultivated in ponds with larger areas during the winter should be transferred to the small pool of l-2 acres of water. Nurture. Disinfect small ponds before pooling, and open and raise broodstock with good growth and broodstock with poor growth and development. Density should be 120-150 kg of broodstock per mu. And it is better to place the broodstock in the pond per acre for one time. This will not only facilitate the prenatal intensive cultivation of those broodstock with poor growth and development, prompt the rapid maturation of their gonads, but also enable them to catch the pro-fish elbow at the time of production and will not disturb other broodstock that have not yet spawned, and they are found to be sick when wounded in the pool. The broodstock can also be treated with drugs promptly.
Second, reasonable feeding. After the water temperature rises in the spring, the broodstock is in a stage of vigorous growth and development and needs a lot of nutrients. In the spring cultivation of oysters and broodstock, fertilizing and cultivating food organisms are still the main factors. Before the pool is divided, sufficient basal fertilizer should be applied in the pool. Generally, 300-500 kg of organic fertilizer is applied to the pond per acre. For broodstock broodstock ponds, manure should be used more, and for brood broodstock ponds, livestock manure should be applied more. The topdressing should be less than once in order to stabilize the water quality so that the pool water is both “live†and “fatâ€. The water quality is about 30 centimeters in transparency, and about 15 days before the start of production, it can be applied less or stopped. In spring, grass broodstock should be dominated by green materials, supplemented with fine materials. Pre-feeding of grain buds, malt, buckwheat cakes, etc., and early feeding of lettuce leaves, ryegrass, etc., and then transferred to only cast green material. Near the ovulation period, the food intake of grass broodstock that has matured gonads will be significantly reduced and even stop feeding. Green broodstock is mainly fed with snails and clam meat, supplemented with bean cake or compound feed.
Third, scientific management of water. After the beginning of spring, the water depth of the pond should be controlled to about 1 meter. This will help the water temperature rise, promote the growth and reproduction of food organisms, and also help the fish to eat. The broodstock pond is often filled with fresh water; keeping the water fresh and increasing the amount of dissolved oxygen in the water is beneficial to the growth and development of the broodstock. In the early stage of water injection, the broodstock and bream broodstock are fed once every 10 days. Grass and blue brood pools can be filled with water every other day. Grass and blue broodfish ponds can also be filled with water every day. Note The new water should be carried out in the afternoon. Each injection of water for 3-5 hours will increase the pool water by 15-20 cm.
Fourth, prevention and treatment. The broodstock ponds should spit lime water once a week and use 10-15 kilograms of quicklime per mu. And timely adjust the pool water pH, so that the pro-fish pond acid best maintained within the range of 7-8.5, in order to promote the robust development of fish eggs. To prevent bacterial fish diseases, 1 g of bleaching powder per cubic meter of water, 5 g of the sterilizing king and 20 g of quick lime. To prevent parasite fish diseases, 0.8 g of trichlorfon, 0.5 g of copper sulfate, or 0.7ppm copper sulphate and ferrous sulfate (5:2) will be splashed once every half-month in each cubic metre of water.
Four measures of spermatozoa in the conversion period of broodstock
With the arrival of spring, with the gradual increase of water temperature, the development of gonads in broodstock is gradually transformed, especially before the spring to mid-May, the ovary coefficient of broodstock can reach 15-20%. Therefore, the management of the broodstock conversion period is crucial to the improvement of the annual fish production, and the following management measures must be strengthened.
