What are the differences in feed production lines for different types of fish?

 

 

Fish feed factories don't just produce "one type" of feed. Grass carp, bass, and tilapia eat different feeds, and the production lines need to be adjusted accordingly. For example, some production lines produce floating feed, while others produce sinking feed, and the equipment and processes differ. If these processes are mixed up, the fish simply won't eat the feed produced.

 

 

Grass carp prefer floating feed, bass prefer sinking high-protein feed, and tilapia prefer semi-sinking medium-protein feed. Since their needs differ, the production line naturally needs to be adjusted. The main differences lie in three steps: "forming equipment," "formulation and ingredient mixing," and "pellet processing."

 

 

1. Differences in Feed Production Lines for Three Types of Fish

Grass Carp Feed Production Line: Emphasizes "Floating Ability + Medium Protein"
Forming Equipment: Uses an extruder (not a pellet mill), which heats and extrudes the feed to create small air bubbles, making it float on the water, which suits the grass carp's habit of feeding at the surface.
Formulation: High proportion of corn flour and wheat bran (e.g., 35% corn flour, 20% wheat bran), low proportion of fishmeal (10%-15%), and protein content controlled at 25%-30% (grass carp are omnivorous and do not require high protein).
Pellet Processing: The extruded pellets are cooled to room temperature and then sieved to remove fine powder, ensuring uniform pellet size (generally 4-6mm, suitable for grass carp).

 

2. Bass feed production line: Focusing on "sinking ability + high protein"
Molding equipment: Using a high-pressure pellet mill (not an extruder) to compress the raw materials very tightly, resulting in high density and rapid sinking to the bottom, which matches the bass's feeding habits at the bottom of the water;
Formula: High proportion of fishmeal (30%-40%), 20%-25% of soybean meal, and low proportion of cornmeal (around 15%), with a protein content of 40%-45% (bass is carnivorous and requires high protein);
Pellet processing: After pelleting, cooling must be thorough (moisture content below 10%), and the pellet surface must be polished smooth with a polishing machine to prevent them from scattering after water ingress, which would affect the bass's feeding.

 

3. Tilapia Feed Production Line: Emphasizing "Semi-sinking + Medium Protein"
Forming Equipment: Uses a standard pellet mill, but adjusts the die hole shape to ensure the pellets are half sinking and half floating (semi-sinking), conforming to tilapia's habit of feeding in the water's middle layer;
Formula Ingredients: High proportion of soybean meal (30%), corn flour 25%, fish meal 15%-20%, protein content 28%-32% (tilapia are omnivorous, medium protein is sufficient);
Pellet Processing: No polishing is needed after cooling, but the pellets' water resistance must be checked (they should not disintegrate after 20 minutes in water) to prevent them from disintegrating too quickly in the water, making them inaccessible to tilapia.

 

 

 

 

Fish feed factories adjust their production lines based on orders. For example, if they're making grass carp feed today, they'll use an extruder and follow the grass carp formula; if they're making bass feed tomorrow, they'll switch to a pellet mill and follow the bass formula. One production line can be adjusted to produce multiple types of feed, eliminating the need for three separate lines and saving costs.
