How to reduce the pollution of baby fish feed on water quality

High-density seedlings and large-scale feeding of artificial compound feeds are two distinctive features of intensive aquaculture. Artificial feeds are the main source of nutrition for intensive aquaculture, and the large-scale use of artificial compound feeds causes pollution of aquaculture water bodies. One of the main reasons. To solve the problem of feed pollution, we must control pollution sources from the perspective of nutrition, so as to achieve the goal of green breeding.

1. Reasonable control of the proportion of feed ingredients

At present, some manufacturers often only consider the demand for protein from aquatic animals when configuring aquatic feeds, and neglect the demand for energy from aquatic animals. The main reasons for high phosphorus and high nitrogen pollution are caused by adding large amounts of fish meal. When formulating the formula, the energy content of the feed can be appropriately increased and the protein content can be reduced, thereby reducing the degree of ammonia nitrogen pollution caused by the high protein nutrition level.

2. Improve the biological value of proteins

The large amount of nitrogenous substances excreted by aquatic animals is mainly derived from those undigested crude protein and amino acids in feed. The use of an ideal protein model to improve the balance of various amino acids in the protein can increase the biological value of the protein, effectively reduce the level of crude protein in feed, increase the nitrogen utilization rate in the feed, and reduce the nitrogen excretion in the feces. This will not only save a large amount of natural protein feed resources, but also reduce the degree of nitrogen pollution from intensive aquaculture to the environment.

3. Reasonable use of additives

The rational use of some additives can improve the quality and flavor of feed to a certain extent, promote the feeding of aquatic animals, increase the utilization of feed, and thus reduce the degree of pollution of the water environment.

Peptide preparations: Peptides are highly effective bioactive substances that have no drug residues and do not produce drug resistance. In order to reduce feed costs, it is often necessary to add a certain amount of vegetal raw materials when formulating aquafeeds. The use of peptide preparations can not only improve the palatability of feed, but also can comprehensively promote the digestion and absorption of feed nutrients, improve the feed utilization rate, thereby greatly reducing the excretion of organic substances, nitrogen and phosphorus and other nutrients in aquatic animal excreta. Reduce the contamination of undigested material in the feed to the water environment.

High-Efficiency Minerals: Minerals are an indispensable nutrient in aquatic animal life activities and aquaculture production processes. Although aquatic animals can absorb some of the minerals from the water environment, they are still unable to meet the growth needs and therefore must be in the feed. Supplement with a certain amount of minerals. At present, the use of feed mineral additives in China still stays at the inorganic salt stage, and the minerals added in the form of inorganic salts have a very low utilization rate in animals, which easily leads to an increase in the amount of added minerals and the pollution to the environment is becoming more and more serious. Mineral additives in the form of organic salts can increase the bioavailability of minerals, reduce their added amount in feed, and reduce the pollution caused to the environment, so as to achieve the purpose of reducing production costs.

4. Improve processing technology

Feed processing techniques (such as crushing, mixing, granulating and puffing, etc.) may affect the utilization of feed nutrients by aquatic animals. When producing aquafeeds, they should be based on the habits of different breeds, different stages of development, and different physiological functions. Using appropriate production techniques, formulate high-quality feeds suitable for its intake and digestion.

The inevitable development of the development of the low-pollution aquaculture feed industry and aquaculture industry is also a prerequisite for relieving the vicious circle between the aquaculture industry and the environment and producing pollution-free aquatic products. In general, the application of low-contamination aquafeeds will be the direction of future aquaculture development.

Red Light Therapy Bed

Red light therapy benefits and what is red light therapy?

A safe, all natural process that encourages your body to naturally produce enzymes, elastin fibers and collagen that support the skin`s structure. Thus producing younger, smoother and firmer feeling skin. Here are some common questions that our members often ask about Red Light Therapy:

Q: Can I wear makeup in the Red Light Therapy bed?

A: Yes, makeup can be worn and should not affect the performance of the therapy.

Q: Can I wear my clothes in the Red Light Therapy bed or should I be nude?

A: The skin that you wish to be treated should be fully exposed to the light.

Q: Will the treatment interfere with or be affected by any medications I use?

A: If you use medications such as Tetracycline, Digoxin (used for heart irregularities) and photosensitizing drugs (e.g., tranquilizers, sulfa drugs, oral anti-diabetic drugs, antidepressants, and steroids), please consult your physician before using Red Light.

Q: Are there any special lotions I am supposed to use during or after treatment?

A: No.

Q: Will Red Light help with Seasonal Affective Disorder (SAD)?

A: Red Light, as well as other light therapies, has been proven to improve Seasonal Affective Disorder (SAD).

Q: How warm does the Red Light Therapy bed get?

A: The feeling of the heat has been compared to a nice warm 80-degree day (not actual temperature of room). We do provide a fan for use in the room to keep you at a comfortable temperature.

Q: How long after the previous user do I have to wait to use the Red Light bed?

A: We tend to schedule 30 minutes between appointments so that we can allow the bed can cool down (not required) for the next user`s comfort.

Q: Is it okay to wear contacts while in the Red Light bed?

A: That depends on the individual, some people may experience a dry eye sensation.

Q: Do I need to wear some sort of eye protection (similar to tanning goggles)?

A: It is not required that you wear eye protection, nevertheless the lights are very bright and may be uncomfortable for some individuals with sensitivities to light.

Q: Is Red Light Therapy similar to tanning?

A: No not at all. You will not get a tan from Red Light Therapy, nor does it expose you to damaging UV rays.

Q: Will I have to do this indefinitely to maintain results?

A: Yes, it is recommended to start with a commitment of 20 minutes 3-5 times per week for the first 1-4 weeks, then 2-3 times per week for the following 4-12 weeks, and finally 1-2 times per week to maintain results.

Red Light Therapy dramatically reduces wrinkles & fine lines, eliminates stretch marks in most clients, and relieves joint pain & increases circulation!
