In recent years, as the scale of large yellow croaker farming has increased year by year and the number of farmed animals has increased year by year, the price of large yellow croaker has also declined year by year. In the past, the era of cost-free and how to raise money has disappeared. Farmers should reduce aquaculture costs from many factors such as reducing mortality and improving feed utilization. Otherwise, they will be high-input, low-output, and even loss-making. Feed costs account for 60% to 70% of aquaculture costs. Therefore, it is particularly important to reduce costs in terms of improving feed utilization. After understanding, the author summarizes the following points to improve the utilization rate of feeds: 1. Choosing a favorable large yellow croaker in the breeding sea area is a warm-temperature inshore fish. The suitable salinity range is between 17 ‰ and 28 ,, and the water dissolves. The amount of oxygen is required to be 5.0 mg/l or more and the pH value is 8.0. If these requirements are not met, the appetite of large yellow croaker will be greatly reduced and the feed will be wasted. Therefore, new farmers should choose to breed large yellow croakers in the sea where they can flow straight and stable. The flow rate should be about 1m/s, the water depth should be more than 5m, and the bottom of the cage should be more than 1.5m above the sea floor at the lowest tide level. Between 8°C and 29°C, the salinity is between 13 ‰ and 32 ,, and the transparency is about 1 metre. In addition, the large yellow croaker is very sensitive to the sound response. The vibrating sound, the percussive sound, and the moving sound all make it frightened and stop feeding. Therefore, the culture area should be far away from the fairway. Second, the selection of high quality and low price of feed on the sea area not only chilled fish species, there are many varieties of complex feed, quality, grades vary, promotional methods varied, some farmers were low sense of the sense of confusion, to buy some deterioration Small fish feeds or blind purchases without considering the different requirements of different feeding stages on feed nutrients and particle size, and even feeds on large yellow croakers with livestock feed or herbivorous fish feeds, such as large yellow croakers fed with sweet potato rice, resulting in large Yellow croaker has malnutrition, slow growth, high morbidity and mortality, high cost and low efficiency. Therefore, farmers must carefully purchase high-quality, flat-rate feed. High-quality feed can not only fully guarantee the nutritional needs of large yellow croaker, but also increase the disease resistance of large yellow croaker. When purchasing compound feed, the manufacturers that produce the product must talk about the quality of reputation, feed nutrition indicators, and particle size must meet the requirements of the fish. The feed has a low feed rate and reasonable price. Before purchasing a certain amount of feed in bulk, you should purchase a small amount of feed first, and test the effect of the feed in half a month. If the effect is good, you can continue to purchase, and if it is not timely, you can replace the brand. The purchase of compound feed should be limited to within one month. The choice of chilled fish bait should be chilled fresh fish that is not deteriorating, and the effect of feeding large yellow croaker with bonito is good. At reasonable prices, try to buy fresh fish and feed the croaker. Third, the feeding method should be appropriate when the level of feed efficiency and the amount of feeding is appropriate, there is a close relationship between the proper methods. Some farmers do not attach importance to feeding techniques, and the amount of feeding and the number of feedings are inaccurate, often resulting in a large amount of feed waste. In order to improve feed efficiency, the following points must be mastered: (1) Before hand-feeding, the water should be stroked in the cage to form a conditional reflex to allow the fish to feed on the ground; 2) Feed the fish quickly after feeding into the fish to feed the fish. Disperse or sink so far; 3 to take care of fragile large yellow croaker can also eat food, sprinkle the area as much as possible, and finally make a small amount of feed around the cage; 4 according to the weather, tide, color, fish activity Regular fixed-point feeding. Fourth, do a good job of day-to-day management of three points raise seven points, management is directly related to the level of feed efficiency. Therefore, we must pay enough attention, especially in the peak season of large yellow croakers from May to October. We must strengthen the management: 1) Use cages of various sizes of nets, and regularly screen individuals for non-uniformity to promote uniform growth; 2 Patrol, inspection, prevention of fish escape accidents. Fish diseased fish and dead fish in a timely manner to prevent the spread of fish diseases; 3 Replace cages in a timely manner, clean cages, keep cages clean and free of water exchange; 4 large cages are more conducive to feeding and growth than small cages, and large cages can be used. Use large cages as much as possible. Fifth, do a good job in disease prevention and treatment. Fish disease is also an important factor affecting feed efficiency. Due to the high stocking density of cage culture, once the fish body becomes ill, cross-infection spreads quickly and the disease condition is difficult to control, which can easily cause batch death. Prevention is more important than prevention. Prevention is particularly important. Therefore, we must do a good job of disinfection at ordinary times and find the diseased fish timely treatment.
What is SARMs? Selective androgen receptor
modulator, are originally in the form of raw powders, mainly acting on androgen
receptors, they have similar effects as androgen drugs, but they are not like raw
steroids, their effects are more selective, which may also bring more
application than androgen drugs. As far as products on the market are
concerned, SARMs can be taken orally, which has a greater advantage than
androgen drugs - most androgen drugs require injection. The advantages of
SARMs, besides oral administration, the ratio of anabolic to masculinity is
greater than 3:1 and can even reach 90:1, which means it will have fewer
negative male problems. We all know that masculinization will bring problems
such as hair loss, prostate, and masculinity, and a lower male index will
facilitate the promotion of SARMs as a drug for the treatment of osteoporosis.
Of course, the dose used for treatment is much lower than the amount used by
athletes.
SARMs is not as well known as steroids.
Considering the cost of steroids, most users will choose to buy Raw Steroids from overseas to make oils by themselves, if people don`t like brewing they may
choose semi-finished oils which just need to be filtered, or use the
similar things such as Human Growth Hormone, Bodybuilding Peptides to instead. So why we choose SARMs raw, following are the advantage of
SARMs for your reference.
Gain muscle
Prevent muscle loss during cutting and
weight loss
Athletic performance
Increasing fat loss
Increasing endurance
Injury rehabilitation
PCT use after steroid cycle
Advantages of SARMS when compared to
steroids:
Oral use (don`t need to inject)
Same effects to testosterone (libido, gain
muscle, fat loss)
No conversion to Dihydrotestosterone (DHT)
No conversion to Estrogen
No harsh liver toxicity
Does not inhibit your HPTA to the large
extent of steroids (no large reduction in LH or FSH)
Legal and not scheduled
Undetectable (selected SARMS)
Although steroid hormones are currently the
most commonly used drugs for athletes, the risk of athletes using these drugs
is increasing as their detection sensitivity continues to increase.
SARM specifically stimulates androgen
receptors in muscle and bone cells, thus contributing to muscle and bone
growth, while having little effect on other cells in the body (unlike regular
steroids). They have a specific affinity for certain tissues, such as muscles
and bones, but not for other tissues such as the prostate, liver, and brain.
This means faster muscle and bone growth without unwanted growth in other parts
of the body.
SARM also does not break down into unwanted
molecules that cause side effects, such as DHT and estrogen, just as easily as
anabolic steroids. Finally, because SARMs are not as effective as regular
steroids, they do not significantly inhibit the production of natural
testosterone, making it easier to recover from it, and rarely require
post-circulation therapy (PCT).
