Fish feed pellet is of higher nutrition, stable performance, and it can float in the water for a long time without polluting the water. What’s more, it is easy for the fish to digest and absorb. So it enjoys a great reputation among the fish breeders.
If we choose the fish feed pellet, we’d better obey these three points.
First, in order to ensure the fish grow rapidly, the nutrition of the feed pellet must totally satisfy the need of the fish.
Second, we must pay attention to the security. That is to say, we should test whether the pellets add the harmful additives or not. Or else, the fish will have an ugly body shape and even influence our health seriously.
Third, cost performance, if the quality of the pellets is the same, we should compare the price of them. On the contrary, we should compare the quality.
When we feed the fish, the quantity of the pellets is determined by some factors, such as the temperature of the water, the weight of the fish, the dissolved oxygen, etc.
First, the change of the water temperature will influence the strength of the fish metabolism, and then it will influence the fish’ food ration. Generally, at the scope of the proper temperature the fish’ food ration will increase with the temperature rising.
Second, if the weight of the fish increases, we will feed the fish more pellets than before.
Third, the fish’ food ration will be larger when they are in the wave of the high dissolved oxygen, and they have a high digestion rate, the efficient of the fed pellet will also high.
Attention Should Be Paid to When Feed Fishes
First, because the moisture of the pellet is 12%～14% when pelletizing, so the pellet should not store for a long time. The pellet will mildew and get wet, so the nutrition value of the pellet will be reduced, it is bad for the fish to grow. The best way is that after producing the pellets, we feed the fish at once.
Second, we can add proper salt to the pellets when feeding the fish; this can kill the bacteria and prevent the fish getting ill.
Third, the fish don’t have a stomach, so the pellets stay in the intestinal tract for a short time, causing the pellets have a low efficient. So in the fixed gross, we should increase the feeding times and reduce the quantity of the pellets.
Forth, fertilize reasonably. The feed pellet for the common fish has a high-usage and they can grow rapidly. But for the fat water fish, they only eat the feed pellet not enough, and the water is light, so we should fertilize the water to improve the nutrition of the fat water fish.
Fifth, the diameter of the pellets should adjusted with the fish’ growing. When the fish is infant, and the water temperature is low, grow slowly, the diameter of the temperature should be controlled within two millimeter. With the rising of the water temperature and the growth of the fish, the diameter of the pellets should be 3-3.5 millimeter. And in the later period, the diameter of the pellets should be 4-4.5 millimeter.
Fish Feed Pellet Advantages and Disadvantages
First, improve the digestion rate of the fish feed pellet.
Second, it can attract the fish, so the fish can’t picky.
Third, it is low cost for the storage and the transportation.
Forth, meet the hygienic standard.
First, need steam.
Second, the machine is easily damaged.
Third, the machine which produce the fish feed pellet has a high electrical consumption.
