How to Distinguish the Quality of Fish Feed
Fish feed is food for ornamental fish. Whether the fish feed is of high quality should be checked from multiple aspects such as color, smell, water resistance, and specifications. In addition, the inspection of high-quality fish feed should also take into account its nutritional formula additives, etc. If you keep fish feed for a long time, you will slowly form your own judgment criteria for the quality of fish feed.
1.Raw material composition
Generally speaking, the main ingredients of many fish feeds are composed of protein raw materials such as fish meal, soybean meal, and cottonseed meal. The appearance color of the product has the properties of its raw material composition, which is generally dark yellow-brown or brown. If the color of the fish feed is found to be too light or very strong, it is mostly added with other pigments and preparations, and it cannot be purchased.
2.The smell of the feed
Finished fish feed generally has the aroma of soybean meal and the fishy smell of fish meal. In addition, some fish feeds are added with antibiotics, such as allicin, so the feed has the smell of medicine. The fishy smell of this kind of fish feed is long-lasting and light, and the fishy smell will last for a long time when placed in water. If you find that the fishy smell of the fish feed is too strong when selecting, and it disappears quickly after being soaked in water, then this kind of fish feed is not worth buying.
3.Water resistance and particle size
Fish feed is soaked in water for fish to eat, so it needs to be water resistant. Generally, good fish feed can be water resistant for up to 20-30 minutes, so that fish have enough time to eat slowly. In addition, when choosing fish feed, you should also check its rules, check its production date and shelf life, check the composition and nutritional ratio of the raw materials, so as to choose the healthiest fish feed for fish.
Fish feed is currently made in various shapes and sizes. When choosing, you should pay attention to choosing fish feed with appropriate particle size. Generally speaking, the finer the particle size of fish feed, the better, the lower the feed coefficient, and the higher its utilization rate. It will also be healthier and more convenient for fish to prey on, and will not cause indigestion.
