Make more nutritious fish feed

Fish need the correct balance of protein, carbohydrates, fats, vitamins and minerals to grow and stay healthy. This type of feed is considered complete feed.

So do you know lima, which is popular in fish feed machines.

Protein is the most important part of building a fish school. During their growth stage, omnivorous fish such as tilapia and carp require 25-35% protein in their diet, while carnivorous fish require up to 45% protein to grow at an optimal level. Generally speaking, young fish (fry and fingerlings) need a protein-rich diet more than they are in their growth stages. Proteins are the basis of structures and enzymes in all living organisms. Protein is composed of amino acids, some of which are synthesized by the body of fish, while others must be obtained from food. These are called essential amino acids. Among the ten essential amino acids, methionine and lysine are usually limiting factors, and these need to be supplemented in some vegetable basic feeds. 

Lipids are fats, and they are high-energy molecules needed by fish in their diet. Fish oil is a common ingredient in fish feed. Fish oil is rich in two special types of fats, omega-3 and omega-6, which are good for human health. The amount of these healthy lipids in farmed fish depends on the feed used.

 

Carbohydrates are composed of starch and sugar. This ingredient in the feed is a cheap ingredient that can increase the energy value of the feed. Starch and sugar also help to combine feed into pellets. However, fish cannot digest and metabolize carbohydrates well, and most of this energy is lost.

 

Vitamins and minerals are necessary for fish health and growth. Vitamins are organic molecules that are important for development and immune system function, synthesized by plants or through manufacturing. Minerals are inorganic elements. These minerals are necessary for fish to synthesize its own body composition (bone), vitamins and cell structure. Some minerals are also involved in osmotic adjustment.

So come to see the animal feed production line in Lima. I think this will help you a lot.

 

Floating or sinking fish feed pellet

 Floating or sinking fish feed pellet? Whether to use floating or sinking pellets mainly depends on which type of fish species that you have.

Features of floating and sinking fish feed pellet 

Type of feed Sinking Floating / slow sinking
Advantages
1. Good water stability
2. Cheaper than floating pellets and so lower capital costs.
3. Terrific for fast-moving stream
4. Better for fish who live in bottom Best water stability
5. Many anti-nutritional factors removed with heat.
6. Environment-friendly
7. Easy monitoring the fish 

Disadvantages
1. Dry ingredients required; vitamins partially lost.
2. Generally higher FCR than the floating pellet.
3. Fish feeding can not be observed. Extruders are more expensive and so a high production cost.
4. Requires more skill in production.

The aquaculture industry is the fastest growing food production industry on the world in the last few years. After this, I must tell you that the fish feed pellet machine in lima is so popular.

It’s approximately 50% of all fish consumed by humans is from aquaculture. Understanding about the requirements and production of fish feed is essential to the development and sustainability of aquaculture as the industry has matured.
When fish are reared in high density indoor systems or confined in cages and cannot forage freely on natural foods or natural foods are absent or where natural foods only make a small contribution to nutrition. Nutrition plays a vital role in improving fish productivity. The farmer should use nutritionally complete feeds. Feed comprises the biggest cost in intensive fish farming. Feeds can be produced either by steam processing, producing compacted, pressure-pelleted (sinking) feeds; or by extrusion, which produces expanded floating or buoyant feeds. Maybe you can go to see the animal feed production line.

Fish Feeds Types

Floating Feed –This type of feed floats on water. In general, floating feeds offer numerous advantages over their sinking counterparts.
Sinking Feed – Sinking feeds are solid feed pellets that are submerged during application. They are more economical.

Processing Technology
Compressed pellet
Steam treated compressed pellet Extruded/Expanded pellet
Processing Equipment
Animal feed pellet mill or ring die pellet mill. Single screw fish feed extruder machine or twin screw fish feed extruder machine.
Which one is better? Floating or sinking fish feed pellet. Generally there is no nutritional difference between floating and sinking feed, whether to use floating or sinking pellets mainly depends on which type of fish species that you have.
Floating Fish Feed Pellet 
The floating fish feed pellet is usually used in larger underlings, food fish and broodfish. Floating on the surface of the water (usually maintaining integrity in the water for several hours), the fish must come up to the surface to eat. The farmer can observe their fish each day, which helps in monitoring their health and vigor. Also they can adjust the amount of feed per day and avoid wasted feed and pond pollution problems.
Sinking Fish Feed Pellet 
But for some ornamental fish like goldfish and koi, sinking fish feed pellet is better for them. Because goldfish being a greedy pet will usually dash and swim towards their food and during the commotion while grabbing the pellets, they will end up sucking air into their stomach as they gulp their meal. Usually what you can observe is that air pockets will get trapped in their poo discharge and prolonged condition are sometimes blamed as the cause of flipping disease seen happening on goldfish. Therefore use only sinking food pellets for your goldfish.
