Nowadays, there are more and more fish farmers. Goldfish is highly sought after as a kind of best fish. Pellet making machine can make fish feed pellets, Zhengzhou Fusmar Machinery is a professional fish feed extruder manufacturer.
In order to make the goldfish grow better and live longer, what kind of fish feed pellet do you need to use for fish farming?
Smells Good
The good feed has a natural fish and shrimp flavor, while poor quality feed adds a lot of flour, smells of greasy spices, and has a salty feeling, a bit like adding MSG or chicken essence. As for the kind of feed that smells of a sour or rancid smell, it is the worst.
Not Muddy
The good feed can keep the prototype in water for a long time, and will not dissolve after being scattered. Poor quality feed will soon become muddy when it is launched, and even the water will become the color of the feed, which is too bad! Of course, some people say that this “long time” is a day, but I personally do not agree. Because if the feed does not dissolve for a day, wouldn’t it be similar in the stomach of a goldfish? It’s much more difficult to digest? So, feed that hasn’t dissolved for a long time may cause enteritis. I personally think that the feed can be kept in the water for 2-4 hours without interference. In fact, the feed should be eaten with goldfish in 3-15 minutes.
Not Greasy
Good feed is launched, the water is still clear, just like no feed. The poor quality of the feed itself is insufficient, so in order to lure the goldfish to eat, it uses oil to fragrant. The surface of that kind of feed looks oily. When you touch the water, the water surface is a layer of the oil film.
Does Not Swell In Water
After a good feed is launched, after a while, the volume is almost the same as when it is dry. For poor quality feed, it swells with water. Everyone knows that goldfish are actually full, but there are still some goldfish that have been strangled to death. In fact, they have eaten inferior feed. It is no problem just to eat it, but the feed quickly absorbs water and swells in the belly of the goldfish, and finally kills the fish. Even if it does not die, it may also cause indigestion or even enteritis.
Soft
Although the good feed keeps its shape not muddy for a long time after being launched, its practical fingertips become muddy with a light touch, which shows that it is easy to decompose and digest like porridge, suitable for the delicate and fragile intestines and stomachs of goldfish. Oh, the goldfish has no stomach, but because of this, the intestines of the goldfish are more likely to malfunction, so care must be taken.
Protein Content Above 30%
In addition to the “wild vegetable” feed specifically for goldfish, the goldfish feed as a staple food must have enough protein so that the fish can grow a beautiful domineering gas type, and if you want to create a thick and atmospheric head tumor for the goldfish, then the protein content Even more than 40%, even close to 50%. In addition, I personally think that it is meaningless for a goldfish that does not require hair to be too high. Instead, it will increase the gastrointestinal burden, not exceeding 40%. There are also goldfishes that are more than two years old and have grown up. There is no need to use high protein for growth, just normal feed.
Good Hydrophilicity
Good feed requires high protein content and low-fat content, which means low oiliness. And low oiliness will be more hydrophilic, hydrophilic is easy to combine with water, such feed is easy to digest and absorb. Some sinking feed of average quality is thrown into the water, and there are many small bubbles hanging on it, which is not good.
Add Beneficial Ingredients
Generally, spirulina is added to the goldfish feed. This is equivalent to vegetables, which is easy to digest and has the effect of making the goldfish more colorful. There are also probiotics. Like the bifidobacteria in yogurt, probiotics are added to the goldfish feed to help the goldfish digest and regulate the stomach. Of course, like protein content, we don’t have professional equipment to do ingredient analysis, and we can’t see if we actually added those things. First, it depends on the ingredient description, and second, we still have to rely on word of mouth. Choose a feed, first find a merchant to try it out, and feel good, then buy a big bag. If you don’t have a trial package, you can also buy the 50g and 100g small bags. If you feel good after using them, you can buy big bags. Don’t be greedy for cheap, buy 5 kilograms at once, and after feeding twice, you will find that the fish is in poor condition and cannot be refunded, which is a waste.
