1. Dough and pie feed It is a feed processed into powdered meals by spraying oil which can play the role of waterproofing and increasing energy, adding water and binders. The binder is mainly starch, which has good water stability and is suitable for cultivating shrimp and small fish. 2. Extruded floating fish feed A special extruder process. A screw extrudes powdered feed under high temperature and high-pressure conditions. This feed has low density, good flotation, and less nutrient loss. I...

There are causes and treatments for fish floating heads 1. Floating head caused by acidic water quality Problems with acidic water quality cause fish to float from early evening until dawn, and farmers can throw quicklime into the ponds in such a situation. And prepare a PH test paper to check the water quality every time. 2. Floating head caused by fish disease The long-term use of disinfection drugs in the breeding pond causes a large amount of suspended matter and harmful bacteria in the w...

Most people in the aquatic feed farming industry are familiar with feed extruder machine. Howerer, For many aquatic products farmers and small beginner of feed manufacturers/suppliers, it may not be very clear about the difference between single-screw extruder and twin-screw. Now, let us tell about what is the difference between single screw and twin screw extruder?     1. In terms of structure, the structure of the single-screw extruder is simpler The single-screw extrusion and ...

With the emergence of twin-screw extruder machines with large specifications and large output, the use of twin-screw extruders can achieve greater production efficiency and give full play to the advantages of extrusion technology. The double screw extruder machine has a wide range of raw materials, high starch gelatinization degree, much higher water stability than ordinary pellet feed, adjustable product density, and can process floating, slow-sinking, fast-sinking feeds, and high moisture, ...

The feed extruder machines are divided into single screw and twin screw extruder. Today, let us talk about the twin screw extruder   Firstly： Principle of twin screw extruder machine The twin extruder machine also called double screw extruder machine. Twin screw extruder is developed on the basis of the single screw extruder. In the barrel of the twin-screw extruder, two screws are arranged side by side. According to the relative position of the screw and the direction of the screw, i...

If you want to start a fish feed production business, you need to do the following: Before you start the fish feed production business, you need to have the perfect business plan for making fish feed. First, you need to understand how the fish feed is made, now look at the details: You need to go through the list of licenses, permits, and registrations required to start a fish feed production business. The second is the land needed to start a business. The third is the list of ingredients ne...

1. Sewage is generally due to poor water quality. The water consumption of fish ponds is relatively large, so it is impossible to use tap water. Water must be diverted from nearby rivers and reservoirs. If the water here is not clean, it will easily lead to the deterioration of the water quality of the fish pond, thus threatening the survival of the fish. 2. The silt at the bottom of the fish pond is too thick, and the water quality is also easy to deteriorates. It will not only turn black bu...

The aerator is to increase the contact area between the water body and the air to infiltrate the oxygen in the air into the water, so the aeration effect of the aerator. It is directly proportional to the sufficient degree of contact with water and air, and inversely proportional to the amount of dissolved oxygen in the water. The aerator is equipped with three functions: aeration, water stirring, and aeration.   Reasonable use of aerators can effectively increase the amount of dissolved...

Single machine introduction of fish feed equipment： 1. Flour mixing machine: Add a certain proportion of water to the raw materials such as corn flour, rice flour, soybean flour, meat flour, cereal flour, additives, etc., and mix well. 2. Feeding machine: The motor is used for screw conveying, and the mixed raw materials are conveyed to the feeding hopper of the extruder to ensure convenient and fast feeding. 3. Twin-screw extruder: Under the conditions of high temperature and high-pressure ...

01. Characteristics of extruded floating fish feed Convenient feeding and management The aquatic extruded feed can be suspended on the water surface for a long time, and there is no need to set up a feeding table when feeding, only fixed-point feeding is enough. Fish need to float on the surface of the water when ingesting, and can directly observe the fish’s eating situation, adjust the feeding amount in time, and understand the growth and health of the fish in time. Therefore, the use...

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. 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...
