The difference between sinking pellet fish feed and floating pellet fish feed
Why is floating fish feed better than sinking fish feed?
People have different views on whether floating or sinking fish feeds are better fish food for your fish. But before I start, I want to state that both of them have their advantages, both of them have their advantages, for fish farms or fish feeding industry, where people grow a large number of fishes, floating fish can be a good choice.
- Sink pellets are cheaper than floating fish feed and can be used for pond fish farming. But floating fish feed is better, because the use of floating fish feed is not easy to cause waste, and it is also convenient for farmers to directly observe the feeding behavior of fish and other conditions.
- The main reason is the difference in craftsmanship. The effect of professional people is similar. For non-professionals, it is better to use floating water. In addition, from the perspective of environmental protection, floating water is a general direction.
- Suitable for fish of different species and habits to feed on floating water, suitable for pelagic fish, such as most tropical fish and betta fish, submerged fish, suitable for pelagic fish, cold-water fish such as goldfish, you can refer to the website Data to determine what kind of food they eat. The floating feed is better and smaller.
The difference between the floating fish feed and submerged feed of tilapia
What is the difference between the floating fish feed and submerged feed of tilapia. There is no difference in the nutritional content of the feed. It just means the utilization rate of the feed. The extruded feed has good palatability. The digestion is good. The utilization rate is high. The shortcomings are high and the price is long-term. Floating food is prone to air bubble disease. The price of sinking material is low. A ton is less than 800 to more than 1,000 yuan. How much more will you spend with floating material. Tell you how to use it. If the bottom of the pond where you put the bait is hard Quality. Just use the sinking material. Tilapia is originally a bottom fish. The digestive function is excellent. There is no difference in the utilization rate of sinking material and floating material. You can still find it if you fall to the bottom. You don’t need to raise tilapia at all. Floating material (if the bottom quality is good). If the silt at the feeding site is deep, use the floating material.
Difference between floating and sinking fish feed
1）Sinking fish feed :
A: Advantage: Good water stability,Cheaper than floating pellets and so lower capital costs.Terrific for fast-moving stream.Better for fish who live in bottom
B: Disadvantage: Dry ingredients required; vitamins partially lost.
Generally higher FCR than floating pellet.Fish feeding can not be observed.
C: Processing Technology. Compressed pellet. Steam treated compressed pellet
D: Processing Equipment. Animal feed pellet mill or ring die pellet mill
2）Floating fish feed:
A: Advantage:Best water stability. Many anti-nutritional factors removed with heat. Environment-friendly.Easy monitoring the fish
B: Disadvantage:Extruders more expensive and so high production cost.
Requires more skill in production. Fish feeding can be observed.
C: Processing Technology.Extruded/Expanded pellet
D: Processing Equipment：Single screw fish feed extruder machine or twin screw floating fish feed extruder machine
How do I make my fish feed float?
1 ）Temperature: The higher the temperature, the higher the degree of puffing. When making fish feed, the temperature of the extruder needs to be lower
2 ）Raw materials:
3）Fish feed formulas generally include the following: protein, fiber, starch, oil, etc. (and some other raw materials, such as vitamins, seasonings, etc.). Fish feeds with high starch content in the formula are more likely to float; on the contrary, protein, Fish feeds with more fiber, oil and other raw materials are more likely to sink.
4） Moisture: The higher the moisture content, the harder it is to puff. The less moisture, the easier it is to puff.
5）Therefore, when making floating fish feed, the moisture content is controlled at about 13%. When making fish feed, the moisture is controlled at about 20%.
Generally, there is no difference in nutrition between floating and sinking feeds. Whether you use floating or sinking pellet feeds depends mainly on what species of fish you are keeping. The fish feed extruder of Lima feed machinery can produce floating/sinking fish feed size of 0.4~15mm feed， just change the different model. Every fish feed machine is attached different size model for free, contact me to get the price of the floating fish feed extruder machine!
