Floating fish feed machines are equipment specially used for the production of floating fish feed. The feed they produce can float on the water surface for a period of time, making it easier for fish feeding and farmers to observe the feeding situation. This type of equipment can produce a wide variety of fish feed, mainly suitable for fish that like to move in the upper layer of water, including the following categories:
Classification by breeding fish species
Freshwater fish feed
Conventional domestic fish feed such as grass carp, green carp, silver carp, bighead carp and other regular household fish feed: This type of feed usually adjusts the nutritional ratio according to the fish growth stage (young fish, adult fish). Floating feed can reduce the waste of feed sinking and improve utilization.
Carp and crucian carp feed: Although these two types of fish will also consume submerged feed, floating feed is easier to control the feeding amount, and is especially suitable for high-density breeding.
Special freshwater fish feed: such as perch, mandarin fish, yellow catfish, tilapia, black fish, etc. This type of fish has high palatability and nutritional requirements for feed, and floating feed can meet their habits of feeding in the upper layer in the water.
Seawater fish feed
Feed for seawater aquaculture fish such as grouper, snapper, and yellow croaker: Floating feed is relatively stable in the seawater environment and is not prone to rapid dissipation. It is suitable for seawater cages or pond farming.
The feed produced by floating fish feed machines is mainly granular, but the particle size and hardness can be adjusted according to requirements:
Small-grain feed: suitable for fry and juvenile fish (such as ornamental fish with a body length of 1-5 cm, freshwater fry), and the particle diameter is usually 0.5-2 mm.
Medium-grained feed: suitable for adult fish stage (such as tilapia, grass carp with body length of 5-20 cm), with diameter of 2-5 mm.
Large particle feed: for large fish (such as perch, bluefish with body length of more than 20 cm), diameter 5-10 mm, or even larger.
Classification by nutritional function
Full-price compound feed: contains all the nutrients (protein, fat, vitamins, minerals, etc.) required for fish growth. It is the main product of floating fish feed machines and can be directly used for daily feeding of fish.
Functional feed: By adding special ingredients (such as probiotics and immune enhancers), it can achieve anti-disease and promote growth and other functions. The floating form facilitates concentrated feeding of fish and improves the utilization rate of functional components.
The feed produced by floating fish feed machines is not only suitable for traditional breeding models such as ponds and cages, but is also widely used in factory recycling water aquaculture, ornamental fish aquaculture and other scenarios. For example, floating feed from ornamental fish (such as koi and goldfish) can reduce water pollution and facilitate feeders to observe the feeding status.
In short, the core of the floating fish feed machine is to make the feed have floating characteristics through process control (such as tempering and puffing). Therefore, its products cover different growth stages of most middle and upper-season feeding fish, and are highly versatile and targeted.
