As the temperature rises, farmed fish begin to be fed feed, and the quality of feed is directly related to the success or failure of farming. There are many ways to identify the advantages and disadvantages of aquafeed. Here we mainly introduce the visual inspection method, which can judge the quality of feed more quickly and intuitively.

 

 

First, look at the packaging bag or label, mainly look at whether there is feed name, nutritional content, analysis guarantee value, net value, net weight, production date, shelf life, factory name, factory site and standards, etc., look at the shape, particle size, color, uniformity of feed, whether there is foreign matter mixed, whether processing is overheated and coking deterioration and discoloration, whether it is agglomerate, whether there are pests, whether there is mold, etc.

 

 

Second, if the feed is moldy and rotten, protein is decomposed, oil rancidity or overheating produces coking, you can smell peculiar smell.

 

 

Third, with a small feed sample placed on the tip of the tongue, you can determine the drying process (water content) or whether there is peculiar smell, irritation, and grit.

 

 

Fourth, use your hands to feel the texture and dryness of the feed.

 

 

Fifth, put the feed into the jar and shake and shake, hear a crisp sound, indicating that the moisture content is low and dry.

 

 

6. The finished feed should have good gloss, consistent color, uniform particles and no peculiar smell. After the pellet feed is crushed, the crushing uniformity and impurities can be observed.

 

 

7. Put a little pelleted feed into the water and see its divergence speed in the water.

 

 

In the inspection, the above methods are combined and applied, high-quality compound feed has no musty smell, no irritation, has grease aroma, no foreign matter, uniform particles, less moisture and dry.

 

   

The above methods allow you to quickly identify the quality of fish feed.
