Among the cost of aquaculture, catfish feed makes up a large proportion due to the high price of fish feed, so Amisy suggests fish farmers to produce catfish by own through nutritious catfish feed production formulation, advanced catfish feed production technology and high performance fish feed machine.
Catfish Feed Formulation
From the countless experience, if catfish farmers want to get more profits, they must attach great importance to catfish feed quality, not only focusing on feed price because high quality feed can greatly increasing economic benefits much higher than feed cost. There are lots of fish farmers realizing that it’s more profitable to choose produce fish feed by own rather than purchasing feed from market because making feed by own can not only save cost but also control what fish eat. Then, it is very significant for those making their own feed to learn about catfish feed formulation knowledge and master the scientific and nutritional formula.
Catfish Feed Production Technology & Equipment
Other than livestock feed, aquatic feed has much higher requirements on feed formulation, raw material grinding particle size, pelleting temperature, water resisting property and percentage of powered pellets. Everyone knows that experience is the best teacher, so it’s better to learn catfish feed production technology and equipment from practice.
Taking the below test for example:
Catfish feed ingredients with percentage by weight in this formulation:
Catfish feed production method:
Weigh all feed stuffs - fully grinding all raw materials via fish feed grinder machine - pass through 50 mesh for screening - mixing - extrusion.
Feeding conditions of this catfish feed:
Feeding amount should be adjusted according to fish eating situation. Generally speaking, daily feeding ratio is 1~3% of catfish weight, and that can be added on the basis of catfish eating conditions. Feeding three times per day, and feeding time is respectively 9:00am, 12:00am and 18:00pm.
Using this catfish feed makes catfish death rate less than 3%, and catfish weight gain rate is up to 149% after 30 days feeding.
