How to Distinguish the Quality of Floating Fish Feed

fish feed pellet

The purpose of fish feed is not only to keep the fish in good health but also to provide the fish with nutritional requirements. Therefore, the identification of fish feed has become a key step. To identify the quality of fish feed, we must start with the appearance and nutrition of the feed.

Observe the Color

The main raw materials of fish feed are fish meal, soybean meal, rapeseed meal, cotton meal, etc., which are uniformly mixed and pellet according to a certain proportion, generally dark yellow-brown or brown. If there are more fish meal and soybean meal, the color of the fish feed will be slightly yellow. When there is a more miscellaneous meal, the color will be dark red. Some fish farmers believe that the darker color of the fish feed, the better, so some production companies have adopted the method of increasing the pelleting temperature to satisfy this consumption psychology of fish farmers. However, if the pelleting temperature is too high, various nutritional factors in the fish feed will be decomposed and lost, and various vitamins added in the production process will oxidize and fail during the high-temperature production process, resulting in insufficient feed nutrition.

Test Water Resistance and Float Time

Putting the fish feed in the water, observe the time for the feed to disperse, and check the thickness and uniformity of the feed. Some fish farmers believe that long water resistance can reduce the waste of fish feed. In fact, we can find that goldfish do not have a stomach and need to eat frequently. Since goldfish have been artificially domesticated, they eat frequently. As long as the number of times of feedings is increased, the goal of not wasting feed can be achieved. The water-resistance of the fish feed is generally 3 to 6 minutes, and the floating fish feed can float on the water for more than 12 hours without sinking, which does not pollute the water source, and reduces fish diseases. However, fish feeds that are too hard and water-resistant for too long are not suitable for goldfish, because the hard fish feed increases the digestion time of goldfish and affect their nutrient absorption.

Smell the Fish Feed

The general fish feed has the fragrance of soybean meal and the fishy smell of fish meal. If antibiotic drugs are added, there will be a drug taste. Some fish feed adds fish flavors and other flavoring agents. If they are fake, they will have a strong fishy smell. Therefore, some fish farmers say that the fishy smell of the feed, the more fish meal is added. If the flavored feed is left for a year or even half a year or so, the flavor will disappear, while the feed emits a sour smell.

Test Taste

Although goldfish swallows the feed, the taste will also affect its food intake. Through our oral touch and taste, feel the hardness of the fish feed, whether it contains impurities (such as sand, soil) and whether there is any peculiar smell. If there is a feeling of gritting teeth or a muddy smell, it proves that the feed contains impurities such as sand and mud; if there are peculiar smells such as bitterness, sourness, and astringency, it indicates that the raw materials or finished feed have mildew.

Observe whether the Feed Ingredients Are Refined Powder

The finer the fish meal or other ingredients are ground, the easier it is for the nutrients of the fish feed to be absorbed and utilized by the goldfish’s intestines to avoid the loss of feed nutrients. But usually, the fine powder feed does not water-resistance for a long time, and the water will be muddy after soaking for a long time. The best detection method is to crush the macerated feed by hand to check whether the raw materials in the feed are finely powdered.

Of course, as a professional fish farmer, we can produce floating fish feed ourselves. So we don’t have to worry about the poor quality of the fish feed. After the fish feed pellet machine is equipped, you can learn more fish feed formulas and produce different floating fish feeds according to the habits of the fish.
