Fish feed floats on the water face due to various reasons like low bulk viscosity, air sacs in extruded feed, low humidity, buoyancy – water stability & other extrusion properties nominated as floating fish feed.
Diet formulation of Floating Fish Feed
The raw materials of floating fish feed are wide and colorful, substantially including fish mess, wheat meal, yeast powder, mineral and vitamin premix, soybean mess, cottonseed mess, peanut mess and rapeseed mess, etC. still, without proper and scientific expression, floating fish feed may show some blights like deficient nutrition, high feed measure, and low feed Application rate. thus, it’s essential to choose a formula with good stability, low feed measure, and high feed application rate, and to master the production process overall.
Composition Of Fish Feeds
Fish feeds, like other poultry feeds, can be divided into six main composites( 1) water,( 2) protein,( 3) fat,( 4) ash,( 5) crude fiber, and( 6) nitrogen-free excerpt.
The main features of fish feed are protein and fat content. The protein in the diet is substantially used for the accumulation of tissues, fat is the main source of energy and the increase of adipose towel. The quantum of carbohydrates in fish feed is generally low because fish are less suitable to digest carbohydrates. thus, the energy in the diet must come from fats and fats have advanced energy viscosity than carbohydrates. As a result, fish feed is more concentrated than that of ranch creatures on land, so protein situations( over to about 40- 45) and energy viscosity are advanced. The digestible protein/ digestible energy rate is an important point of a fish feed and, as a rule of thumb, should more or less act the protein/ energy rate of the growing fish itself. In this way, maximum retention of salutary protein(a precious element of fish feed) is achieved.
How To Make Floating Fish Feed Pellets?
1. Select and prepare raw accouterments according to the formula
Soybean mess, cottonseed mess, sludge kernels, wheat flour, fish derivations, factory derivations, algae, canvases, minerals, proteins
2. Grinding raw materials
Raw materials need to be ground into powder form before producing feed pellets.
3. Mixing raw materials
Because there are numerous kinds of raw materials, it’s necessary to mix the raw materials completely and evenly. The vitamins and minerals can be mixed in small quantities with the constituents while mixing.
4. Extrusion
The feed admixture is passed through a fish feed pellet extruder. Set the proper periphery for the bones, and during extrusion, the pellets are diced or broken into lower lengths.
5. Drying of finished pellets
It’s delicate to store and pack grains with too high humidity content. Sot the grains to a humidity content of lower than 10 or lower. The temperature should be stored below 60 °C.
6. Fish feed pellet packaging
The produced feed can’t be used up at one time, the feed pellets can be put into bags or holders, which can prevent insects, mice, humidity.
Advantages Of Floating Fish Feed
1. High Nutrition Retention
Floating fish feed can stay on the water for a long time. When feed is dissolved in water, it loses some nutritive value. Floating fish feed can save about 20 material losses due to water and waste. High-quality fish feed floats on the water for at least 10 hours.
2. Monitoring the Fish
The consumption of floating feed helps to monitor the appetite of the fish, because the fish can be seen from the shore of the wetland while eating. In addition, the health and vitality of the fish can be regularly observed.
3. Environment-friendly
Afloat fish feed is veritably easy to see. Indeed some remaining feed can be picked up and dried. This kind of feed can be used latterly, and it also helps to keep the water clean. This is veritably salutary to the growth of fish and environmental protection.
4. Easy to Store
Due to high temperature and pressure expansion, the water content of the floating feed( 8- 9) is veritably low. This is why feed pellets are hard and stable. In addition, due to its low moisture content, it’s easier to store.
