Feed formula and feeding method of Pelteobagrus fulvidraco

Pelteobagrus fulvidraco is a carnivorous omnivorous fish, generally foraging at night, including small fish, shrimp, various terrestrial and aquatic insects (especially Chironomus larvae), small molluscs and other aquatic invertebrates. The feeding habits of Pelteobagrus fulvidraco should be fully considered when configuring the feed. Let's take a look at the feed formula and feeding method of Pelteobagrus fulvidraco.

Feed formula of Pelteobagrus fulvidraco

1. Formula 1: fish meal 30%, bean cake 30%, wheat bran 10%, secondary powder 16%, meat and bone meal 1%, mineral 1%, multi-dimensional 1%, fish oil 1%.

Formula 2: fish meal 30%, soybean meal 20%, rapeseed meal 25%, wheat bran 10%, wheat 8%, corn 5%, inorganic salt 2%.

Formula 3: fish meal 8.5%, bean cake 25%, vegetable cake 30%, wheat bran 20%, barley 10%, corn 5%, bone meal 1%, salt 0.5%.

Formula 4: fish meal 15%, bean cake 35%, wheat bran 30%, corn 5%, locust leaves 5%, barley 8.5%, auxin 1%, salt 0.5%.

Formula 5: fish meal 10%, bean cake 25%, vegetable cake 30%, wheat bran 20%, barley 10%, corn 5%, bone meal 1%, salt 0.5%.

Feeding methods of Pelteobagrus fulvidraco

1. Feeding principle: it should be flexibly mastered according to scientific stocking quantity, water quality and different seasons, giving priority to uniform feeding and adequate feeding, not uniform feeding, and feeding as far as possible in accordance with the "four determinations" and "four looks" principles of scientific fish culture.

2. Feeding amount: the feeding amount of Pelteobagrus fulvidraco fingerling put into the pond was less at the beginning, and the scene of group feeding could not appear until 3-5 days later. It is generally believed that if winter fillet fry are put in, the feeding amount is 1%-3% of body weight before April and 5%-8% of body weight in peak growing season.

3. Feeding times: twice a day, one in the morning and one in the afternoon. If there is a floating head in the pond before the wee hours of the morning, in the case of increasing oxygen, the feeding time should be postponed appropriately, for example, the feeding time should be postponed from 8: 00 at 30 to 9: 30 at 9: 30.

How to save feed for Pelteobagrus fulvidraco

1. Strict pond cleaning disinfection: pond cleaning disinfection can not only kill wild miscellaneous fish, reduce food targets, but also kill water pathogenic factors, improve water quality, and make Pelteobagrus fulvidraco have a good feeding and growth environment. There are many wild miscellaneous fish and shrimp in the pond, which compete with Pelteobagrus fulvidraco for bait, and ferocious fish may even eat Pelteobagrus fulvidraco to reduce the feed utilization rate, so we should pay attention to its removal.

2. Reasonable stocking density: reasonable stocking horse bees can improve feed utilization rate, suitable matching varieties, make full use of feed, mutually beneficial symbiosis, achieve harmony in water body, and improve feed use efficiency.

3. Scientific feeding: whether the feeding is standard or not affects not only the growth of Pelteobagrus fulvidraco, but also the change of water quality. The food of Pelteobagrus fulvidraco in natural waters is mainly shrimp, fish and fish eggs and some aquatic insects, aquatic plants, etc., so artificial culture can use fresh animal bait, such as small fish and shrimp, livestock and poultry processing leftovers, and can also feed bean cake, peanut cake, wheat bran and so on.

4. Regular regulation of water quality: as the saying goes, the water quality affects the growth speed and feed coefficient of Pelteobagrus fulvidraco. Pelteobagrus fulvidraco likes fresh water quality, good water quality, rapid growth and less disease, so it can make full use of bait and reduce the feed coefficient.
