What kind of fish feed is good

The quality of fish feed can be distinguished by looking at the color, smelling the taste and pinching with the hands. Generally, yellow feed is better, followed by purple and black, and the finer the crushing is, the better. In addition, it is good to smell the feed close to the nose, if you smell the fresh smell of fish meal, or put the feed in a container and soak it in water, and then slowly wash and pinch it with your hands after dissolving. If there are deposits, it is inferior feed.

1. Look: take a closer look at the feed in your hand to see its crushing fineness and color. If the yellow bean cake contains more ingredients, purple is mostly rapeseed cake, black is mostly cottonseed cake, yellow feed is better, purple and black take the second place. It is better to crush the finer the feed.

2. Smell: smell the feed close to the nose and smell the fresh smell of fish meal (the smell of fresh fish dried in the sun). If you smell the peculiar smell of vegetable oil feet, you will think that the fat in the feed has been denatured and is toxic to fish.

3. Product: put a small amount of feed into the mouth and slowly chew and taste it, and the mouth is numb or spicy after spitting out, indicating that the feed is poisonous to fish.

4. Soak: put the feed in a container and soak it in water. After dissolving, slowly wash and pinch it with your hands. If there is anything immersed (sand or water turbidity), it is inferior feed.
