How to Make Fish Feed Pellets Like a Pro?

HOME > blog

Making fish feed pellets is a crucial aspect of farming that directly affects the health and growth of fish.​ During the fish feed production line, it is vital to follow a series of steps and pay attention to detail. Each step, from fish feed making formula to extrusion and processing, affects the nutritional value and quality of the pellets. Understanding every key step and the associated considerations is essential to ensure the quality and nutritional balance of feed pellets.

There are three main classifications of fish feed:

  • Floating Fish Feed
  • Sinking Fish Feed
  • Slow Sinking Fish Feed/Fish Bait

Different fish feeds have different production process, equipment, and cost. Please contact us for a free consultation.

Mastering the Fish Feed Production Process: Key Steps and Techniques

The fish feed manufacturing process usually includes the following steps. The steps I have provided are for your reference only. The specific fish feed making process can be adjusted and optimized according to the size of the fish feed production plant and the fish food production targets to ensure that high quality feeds are produced to meet the nutritional requirements of different types of fish.

  • Raw Material Preparation

The safety of fish feed pellets is crucial and the ingredients must be contamination free, fresh, and stable. Ingredients for fish feed formulations contain fishmeal, soybean meal, cornmeal, and wheat bran. Starch is an important ingredient in aquafeeds, ranging from 5% to 60%.  Generally, the starch content of sinking fish food pellet is 10%-15%, and the starch content of floating fish food pellet is not less than 20%.

  • Crushing

Before pelletizing, the ingredients must be ground into powder. Grinding of raw materials usually improves the digestibility, acceptability, mixing properties, and pelleting of the feed.

  • Mixing

The crushed ingredients are weighed and mixed in the desired proportions according to the fish feed formulas. Typically, the dry ingredients are mixed first, followed by the liquid materials. Liquid materials such as fish oil may be added at the end and further homogenized.

  •  Conditioning (optional)

Conditioning is a processing step in which the material is subjected to hydrothermal treatment. After conditioning, the powdered feed can improve feed digestibility, improve the stability of pellet feed, kill harmful bacteria, and increase the amount of liquid added to pellet feed. Due to the high price of the wet fish feed extruder machine for this process, this process can be omitted for ordinary feed.

  • Pelletizing

Two types of fish feed making machines can be used for pelletizing fish feed: common fish feed pellet machine and fish feed extruder machines.

  Common Fish Feed Pelleting Machine Fish Feed Pellet Extruder Machine
Fish Feed Pellets Features Fish feed pelletizing machine can produce sinking fish feed and fish bait. Fish feeds are usually produced with less than 13% moisture and a relative density of 1.2-1.3.
The fish feed extruder can produce various kinds of fish feeds, such as floating fish feed, sinking fish feed, slow sinking fish feed, and semi-moist fish feed. The relative density is less than 1.
Fish Feed Pellet Mill Features Complicated operation; Higher price; Higher production cost; Used for producing high-grade aquatic feeds Higher compression ratio; Relatively cheap price; Easier operation

Before buying fish food manufacturing machines, whether it is a fish feed mill producing commercial fish food pellets or a fish farm making its own fish feeding pellets, it is vital to clarify your needs and the characteristics of the fish feed processing machine. Only then can you choose the most suitable pelletizing equipment for your fish feed production line. If you have any questions about common fish feed pellet maker machines and fish food extruder machines, please feel free to consult us.

  • Drying

Dry the freshly made pellet feed to the right moisture. For storage purposes, the moisture content of pelleted feed is required to be no more than 12 to 12.5 percent.

  •  Out-spraying

Spraying grease on the surface of pellets is called pellet greasing. Pellet coating can not only improve the nutritional value of feed, but also improve the palatability of feed.

  • Cooling

Then, the pellet feed is cooled to room temperature and stabilized.

  • Packaging

Finally, the pellet feed is packaged for easy storage. Then the fish pellet feed products should be stored in a dry, ventilated, and cool place to ensure that the quality of the feed is not affected.

Depending on the different needs of fish feed mill plant cost budget, production target and customer audience, it is vital to buy the right fish feed processing line.

Answering Your FAQs on Fish Feed: Solutions to Common Queries

There are some common questions about pellet feed for fish, especially regarding the floating fish feed production line. I hope they can provide you with assistance in the floating fish feed production process and use of floating feed for fish.

  • What is the best fish food pellet size?
  • When fish stocking encounters low water temperature, slow growth and small size, the diameter of processed pellets should be controlled at about 2mm. When the temperature rises, the growth rate of fish species accelerated, the diameter of the feed pellets should be 3-3.5mm, and the later stage should be 4-4.5mm. Therefore, farmers should adjust the fish feed pellet size according to the different periods of the fish species to achieve the ideal feeding effect when using the fish feed extruder machine to process the feed.
  • How much do I feed my fish at a time?
  • Fish do not have a stomach so that the feed stays in the intestines for a very short time, and the utilization rate of feed digestion is not high. ​Therefore, when you feed the fish, it should be put in several times and at different points, so as to grasp the time when the fish species are in semi-starvation state to improve the utilization rate of fish feed.
  • How can I store fish feed to extend its shelf life?
  • Fish feed production process may contain 12%-14% moisture, not easy to store too long. In order to avoid the feed from becoming moldy, it is better to feed the fish while producing.
  • What is a simple way to prevent disease in fish?
  • In order to better prevent the probability of fish disease, before putting into production, operators are recommended to add 1% salt to the feed powder, which can effectively prevent fish disease.
