Freshwater Fish Feed Formula And Feeding Method

Feeding Formula for Freshwater Fish

1. Formula for Carp Feed

Wheat bran 43%; fish meal 30%; bean cake 15%; barley 10%; additives 2%. Feed coefficient is 2.

Bean cake 50%, fishme 15%, wheat bran 15 and rice bran 15. Vitamins 1%, inorganic sodium 1%. Antibiotic leftover 1%. Adhesives 2%. The feed coefficient is 2.

2. Formula for Grass Carp Food

Rice bran 40%, wheatbran 38%, bean cakes 10%, fish meal 10% and yeast powder 2%. The feed coefficient is 1.9. The feed coefficient increases by a portion of the green fodder.

Bean cake 10%, straw powder 80%. If a portion of the green fodder has been added, the feed coefficient will be 4.9.

Corn flour 70%; fish meal 10%; bean cake powder 15%; wheat bran 15%. Other material (based on the total material measurement) can include sweet potato powder 12 %, salt 0.5% and growth substance 2 2%. Calcium hydrogen phosphate 2 2%. The feed coefficient is 4.8.

Sweet potato rattan 80%, sweet potato cake powder 15%, and wheat bran 5%. Other material (based on the total material metersing) could be: sweet potato powder 12 %, salt 0.5%; growth substance 2 %, calcium hydrogen phosphate 2 2%. The feed coefficient is 15. 

3. Formula for Tilapia Food

Rice bran 45%; bean cake 35%; powdered silkworm pupae 10 percent; thorn powder 8 %, bone powder 1.5% and salt 0.5%. The feed coefficient is 2.27.

Bean cake 35%; wheat bran 30%; fish meal 15%; barley flour 8.5%; corn flour 5%; edible leaf powder 5 %, bone powder 1 1%; salt 0.5% The feed coefficient is 2.5.

4. Formula for Herring (black Carp) Feed

Straw powder 40%, powdered silkworm pupae 30%, rapeseed meal 10%, barley powder 20%. 3.

Green hey powder 40%; cottonseed cake powder 30 percent; bean cake powder 10%; rapeseed meal 55%; powdered silkworm pupae 55%, fish meal 5%; barley powder 5%. The feed coefficient is 8.

How to choose the right feed for freshwater fish

These requirements must be met in order for feed to meet its quality:

1. Feed must be either granulated or sinking pellets, or floating pellets.

2. Feed must be complete in nutrition, with all vitamins and minerals.

3. Feeds generally have a 32-36 percent protein content. Feed with high protein content will cost more, but is well worth it, especially if the average fish weight is not lower than 50 grams.

4. With prolonged storage, feed quality will drop. You should use up your feed within six weeks of its production. If the storage time is prolonged, vitamins and other nutrients may lose or be damaged by mildew or other microorganisms.

Tip: All of the above requirements can be met by using fish feed extruders that produce floating and sinking feed pellets.

Feeding method for freshwater fish

Feeding fish in ponds is about providing the fish with the required quality, quantity, as well as adequate time each day. To maximize production and profit.

To balance growth and feed coefficient, the appropriate amount of each feeding and daily food should be approximately 90% of the fish’s total body weight. The feed coefficient will be low if the feeding amount is less than 80% of the fish’s satiety. However, this will result in slower growth. The growth rate will be high if the feeding amount exceeds 100% of the satiety. However, the feed coefficient will be low. Feeding more than 90% of the satiety will cause waste and pollute water quality.

The water temperature and average fish weight are the main factors that determine how much fish feed you need. There are many methods to feed your fish. Here are some of the most common:

• When the fish were active, the feeding rate was set at 3%. The feed would be consumed in between 2-5 minutes.
• Catfish and other fish like catfish usually feed at night so farmers need to train them to eat at daytime. Feeding is best between 8:00 a.m. and 4:00 p.m. or 2 hours after sunrise and 2 hours before sunset.
• You don’t have to feed your fish twice a day. However, you can divide the daily feed into two to three portions and feed once every 6-8 hours. Some fish may grow faster than others, and the feed coefficient for small fish like tilapia or carp will be lower.
• Avoid excessive feeding. Overfeeding is when the fish have not eaten any of the feed left after being fed for more than 10 mins.
• Feed must be consumed immediately and should not be spread.
• Because metabolic waste can cause water pollution, the daily feed amount should be limited.
