In the rearing of catfish, one of the challenges the farmer faces is high mortality rates for those using surface tanks (block ponds, plastic tanks, earthen ponds, etc.). Fish Mortality is usually highest when the fish is initially stocked during the fingerling stage (
The water temperature requirements of various aquatic species in aquaculture, if you want to raise a fish well, you must know its characteristics, for example, what temperature is it suitable for? How much protein do I need to eat? Frequent outbreaks of disease? Temperature is important here, and knowing the optimum temperature for its growth can help improve feed utilization and reduce costs!
When feeding fish with fish pellets, we need to pay attention to the following issues: water quality and dissolved oxygen in the fish pond, properly adjusting the feeding amount, choosing pellet feeds of different diameters, and pay attention to supplementing vitamins and other substances.
In recent years, with the increasing popularity of high-yield fish farming, the use of full-price pellets for fish in fishery production has become very common. However, due to the many feed brands on the market, and there are great differences in quality and grade, the majority of fish farming The user cannot judge the quality of the fish feed. This article introduces a simple method to judge the quality of fish feed using the senses. Namely:’One look, two smells, three twists, four foams, five chews’ for your reference when choosing pellet feed.
Seedlings are weakly disease-resistant and are infected with viruses or bacteria. Lead to diseases such as enteritis. The hematologic toxicity of ammonia nitrogen and nitrite killed the seedlings from hypoxia! From hatching to the steady growth of the seedlings. During this period, the small seedling’s resistance is relatively weak. In particular, the newly hatched seedlings are sensitive to dissolved oxygen, nitrogen, nitrite, bacteria and viruses, and temperature changes in the water.
In the process of raising chickens, farmers will formulate feeds for chickens at different growth stages. When formulating feed formulas scientifically, the nutrients in the feed rations are balanced and comprehensive, and a reasonable mix of feeds is realized, so as to obtain high benefits and low costs.
With the continuous development of the feed industry, the feed production process is becoming more and more specialized. The screening equipment can not only screen out the impurities in the feed raw materials but also grade the feed pellets of different sizes. It can realize the classification of feed raw materials, remove impurities, remove dust, etc.
After the raw materials of feed pellets are pulverized into powdery materials, they need to be put into the mixing equipment for uniform mixing. During the mixing process, some essential ingredients of feed pellets can also be added according to the formula. Homogeneous mixing of raw materials ensures that each part contains the same nutritional content, further improving the consistency of pellet quality at the final production point.
