New technology applications for fish breeding

Gynecological development is a unique form of asexual reproduction where the egg develops into an individual without the involvement of male genetic material. In this process, sperm from the same or different species may be introduced to stimulate egg development, but they do not contribute their genetic material. As a result, all offspring are female and carry only the genetic traits of the mother. This phenomenon is observed in several fish species, such as the Heilongjiang silver carp and Dianchi high back carp. Artificial gynogenesis involves using radiation or UV light to inactivate sperm, which then allows eggs to develop into fully functional individuals under controlled conditions. Over 20 farmed fish species have successfully undergone artificial gynogenesis in China, with significant achievements made since the 1970s. One major advantage of gynogenetic development is its ability to rapidly produce purebred lines. Since all genetic material comes from the female parent, the resulting offspring are highly homozygous, making them ideal for breeding programs. This method can achieve the same level of purity as four generations of sibling mating in just one generation. Additionally, gynogenetic offspring are entirely female, offering new possibilities for monoculture farming. For example, gynogenetic silver crucian carp grow up to 34.7% faster than their maternal counterparts, making them highly desirable for commercial aquaculture. Another notable development is the allogynogenetic silver crucian carp, which was developed by the Institute of Hydrobiology in 1981. This breed combines the traits of silver carp with those of red carp, resulting in a fast-growing, disease-resistant strain. It has been widely adopted in regions like Jiangsu Province, where it has significantly improved yields and economic returns for farmers. In addition to gynogenesis, sex control techniques have also gained importance in aquaculture. By manipulating environmental factors or using hormones, it's possible to influence the sex ratio of fish populations. This is particularly useful in species where one sex grows faster or has higher market value. For instance, all-male tilapia grow twice as fast as females, leading to higher profitability. Techniques such as hormone feeding, three-line systems, and interspecific hybridization have been used to produce all-male or all-female populations, reducing competition and improving overall productivity. Nuclear transfer technology is another cutting-edge approach in fish breeding. This technique involves transferring the nucleus of one cell into another, allowing for the creation of genetically modified fish with desired traits. Studies have shown that fish produced through nuclear transfer exhibit improved growth rates, higher yield, and better nutritional content. These advancements open new possibilities for sustainable aquaculture. Finally, genetic engineering holds great promise for future fish breeding. By introducing specific genes, scientists can enhance growth, disease resistance, and other desirable traits. While still in early stages, this technology could revolutionize the industry by enabling the production of fish tailored to meet human needs. As research progresses, genetic engineering will likely play a key role in shaping the future of aquaculture.

Millimeter Wave Therapy Machine

What is Millimeter wave therapy?

Millimeter wave is 1-10mm electromagnetic wave, it is equal to frequency range 300GHZ-30GHZ, it is a low power, short wavelength, high frequency electromagnetic wave and locates in interchange of the light wave, also called extremely high frequency electromagnetic wave.

Millimeter wave electro-magnetic therapy is supplemented by way of energy through the meridians, body fluid pathways, neural pathways, to regulate patient immune system.

Millimeter Wave Therapy Machine

Millimeter wave application:

Millimeter wave is a kind of green therapy that is safe effective and non-toxic side effects, its unique [Electromagnetic resonance theory of coherent oscillation"and Non-thermal remote effect", have obvious effect on the biological macromolecules, cell and visceral organ, can promote the growth of hematopoietic cell, improve the body` s immune system function, promote tissue repair regeneration, promote inflammation absorption and ulcer healing, coordinate the body`s physiological function by the resonance effect of oscillation frequency, thus get a significant biological effects.

Millimeter Wave Therapy Machine

Millimeter wave Therapy Machine Main functions

1. Non-thermal effects

Millimeter does not treat diseases via increasing body temperature. In the treatment of diseases, no thermal, no pain, no simulation, an internationally recognized green therapy.

2. Distal effects

Millimeter wave can be conducted through the inter-cell, neural, humeral, an other means of the meridian through the irradiation point on the biological activity, or even the effect of the body up to the depth of the lesion.

3. The cumulative effect of time

Millimeter-wave of cell repair and adjusting will take some time, with the increase in the number of treatments:the more intense the millimeter-wave effect on the biological effects of the body, the treatment effect is more obvious.

Millimeter-wave therapy can be applied to many special occasions, either as a single therapy, or combined with a variety of other medical methods for safe usage.
