Embodiment 1

[0019] The high-yield cultivation method in freshwater pomfret pond comprises the following steps:

[0020] (1), Pond conditions:

[0021] The selected area of ​​the pond is 5 mu, and the water depth is 1.8 meters. The ponds were cleaned and disinfected before stocking.

[0022] (2), stocking of fish species:

[0023] 1,300 fish fingerlings of 40 / kg are stocked per mu, and 200 fingerlings of silver carp and tilapia are raised. If mixed with fingerling ponds, 2,500 summer silver carp and grass carp can be placed.

[0024] (3) Feed feeding:

[0025] Feed soybean meal, fish meal, flour, fish meal, soybean meal and additives in a ratio of 4:3:5:2:1 and make pellets. The daily feeding amount is controlled at 8% of the fish's body weight, and it is divided into two feedings in the morning and afternoon. The amount in the morning accounts for 40%, and the amount in the afternoon accounts for 60%. When encountering rainy and hot weather, the amount of feeding is reduced to 5%.

Embodiment 2

[0031] The high-yield breeding method for freshwater pomfret ponds is characterized in that: comprising the following steps:

[0032] (1), Pond conditions:

[0033] The selected pond has an area of ​​3 mu and a water depth of 1.5 meters. The ponds were cleaned and disinfected before stocking.

[0034] (2), stocking of fish species:

[0035] 1,000 fish fingerlings of 20 / kg are stocked per mu, and 150 fingerlings of silver carp and tilapia are raised. If mixed with fingerling ponds, 2,000 summer silver carp and grass carp can be placed.

[0036] (3) Feed feeding:

[0037] Feed soybean meal, fish meal, flour, fish meal, soybean meal and additives in a ratio of 4:3:5:2:1 and make pellets. The daily feeding amount is controlled at 6% of the fish body weight, and the feeding is divided into two times in the morning and afternoon. The amount of feeding in the morning accounts for 40%, and in the afternoon accounts for 60%. In rainy and hot weather, the amount of feeding is redu...

Abstract

The invention discloses a cultivation method with high yield of a freshwater silvery pomfret pond, and relates to the field of an aquaculture technique. The method comprises the following steps: pond condition, fingerling stocking, fodder feeding, oxygenation measures, harvesting and marketing. The cultivation method provided by the invention has the beneficial effects of making the best of resources for production without the need of special equipments, being free from cultivation pollution, being standard in standard of cultivating technology, scientific and standard to feed, and novel in polyculture technology, and the aquaculture quality can be improved to a great extent, therefore the earning of the freshwater silvery pomfret can be improved.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a high-yield culture method for freshwater pomfret ponds. Background technique [0002] Pomfret belongs to the order Perciformes, Pomfretidae. The body is short and tall, with extremely flattened sides and slightly diamond-shaped. The head is small, the snout is round, the mouth is small, and the teeth are fine. Pelvic fins disappear in adults. The caudal fin is deeply forked and the lower lobe is longer. The body is silvery white, and the upper part is slightly blue-gray. Feeds on crustaceans, etc. Pomfret contains a variety of nutrients. 100 grams of fish meat contains 15.6 grams of protein, 6.6 grams of fat, 0.2 grams of carbohydrates, 19 mg of calcium, 240 mg of phosphorus, and 0.3 mg of iron. It is rich in unsaturated fatty acids and has the effect of lowering cholesterol; it is rich in trace elements selenium and magnesium, which can prevent cardiovascular disease...
