Does The Fish Feed Pellet Making Production Line Contribute To Increased Fish Reproduction Rates?

Manual mixing cannot ensure the even distribution of micronutrients, resulting in some broodstock fish not receiving crucial nutrients, while others experience poisoning due to excessive intake. Fully automated aquatic feed production lines, through computer control systems, strictly adhere to breeding-specific formulas. For example, the formula for grass carp broodstock precisely sets the lecithin content to 3%, vitamin E to 50mg/kg, and zinc to 80mg/kg, achieving gram-level precision control from the raw material input stage.

The advantages of floating fish food making production lines extend far beyond precise formulation; they also lie in the improved efficiency of nutrient absorption. Its ultra-fine grinding equipment can grind raw materials such as fishmeal and soybean meal to 100-120 mesh. At this fineness, the particle diameter is less than 0.15 mm, allowing for more thorough absorption by the intestinal villi of broodstock. Compared to traditional 40-mesh grinding, nutrient absorption rate is increased by over 50%. Subsequently, a precise conditioning system, at 85℃ and 0.3MPa pressure, fully gelatinizes the starch, encapsulating fat-soluble nutrients such as lecithin and vitamin E, forming stable "nutrient particles" to prevent loss during water feeding.

The floating fish meal making production line can also achieve "customized production" tailored to the characteristics of different species: grass carp broodstock require high energy to support yolk accumulation, so 20% Peruvian imported fishmeal and 5% soybean lecithin are added, along with 2% brewer's yeast powder to enhance appetite; Litopenaeus vannamei broodstock are fortified with astaxanthin at a level of 0.05%, which not only promotes ovarian development but also gives fertilized eggs a bright orange-red color, significantly improving hatching rates.

The profit increase brought by precision nutrition is considerable. After introducing customized feed from the floating food production line, Lao Li's broodstock spawning increased from 800,000 eggs per acre to 1.2 million eggs per acre. More importantly, the fertilization rate of the eggs increased from 65% to 92%, and the problem of the white eggs that used to bother him almost disappeared.
