Scientific feeding of grass carp
In the process of grass carp breeding, the cost of feed can account for 70%-80% of the whole. The quality of the feed affects the quality and quality of the fish. To raise the fish, the scientific feeding and management of the feed are very important. In fish ponds for cultivating grass carp, water quality, bottom quality, feed, seed, animal protection use, and external facilities are all key factors that affect the success or failure of aquaculture. Among them, feed feeding is closely related to water quality and sediment quality.
How to breed perch?
Perch is one of the common economic fish, and it is also a species for the development of marine aquaculture. At the same time, perch is also one of the important economic fish that grow naturally. It has been artificially cultivated for nearly 20 years. In recent years, driven by the market economy, Big breakthroughs have been made in bass breeding technology.
How to produce fish feed pellets in Nigeria?
Just like other animals, fish requires a feed formula that contains protein, carbohydrates, lipids, minerals, and vitamins for healthy growth. Fish requires mostly protein in their feed.
Extruded floating feeds are favored by farmers in Nigeria because they allow observation of the feeding processing thereby preventing wasteful feeding.
How to breed catfish?
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 (< 10g in size). For farmers that purchase fingerlings, these losses can be crippling to their business and this article shows how to reduce these losses.
Growing environment adapted to all kinds of fish
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!
Four aspects need to be paid attention to when feeding fish with pellet feed
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.
How to judge the quality of fish feed pellets?
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.
Water treatment schemes for fish seedling fields
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.
Four types of raw materials for chicken feed preparation
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.
