How to Choose Suitable Aquatic Feed
Whether fish feed is food for ornamental fish and whether fish feed is of high quality should be checked from multiple aspects such as color, smell, water resistance, specifications, etc. In addition, when checking high-quality fish feed, its nutritional formula additives, etc. should also be considered. If you have been raising fish for a long time, you will gradually form your own criteria for judging 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, cottonseed meal, etc. The product appearance color has the properties of its raw material composition, generally dark yellow-brown or brown. If the color of fish feed is too light or very strong, it is most likely that other pigments and preparations have been added and should not be purchased.
2 Smell of feed
Finished fish feed generally has the aroma of soybean meal and the fishy smell of fish meal. In addition, some fish feeds also add antibiotics, such as allicin, so the feed has the smell of medicine. The fishy smell of this kind of fish feed is persistent and light, and the fishy smell will last for a long time when placed in water. If you find that the fishy smell of fish feed is too strong when you choose it, and it disappears quickly after soaking 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 20-30 minutes, so that fish have enough time to eat slowly. In addition, when choosing fish feed, you should also check its specifications, 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 your 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.
