Principle:

Crispy pomfret is raised with special feed under specific environmental conditions, and the key to crisp meat quality lies in water quality and feed.

In the early years, farmers in Zhongshan only followed the way of raising common grass carp. Feeding for about half a year can grow to about half a catty. It will take 1 year to continue feeding grass carp in the same way.

When the fish grows to about 7 kg, fish farmers begin to feed with broad beans, soybean meal, corn, sugarcane grass, broad bean vines and other materials. After feeding for 4 months, the fish will start to become brittle. This kind of broad beans needs high-quality broad beans from the northeast. After fish eat broad beans, the cell density increases, the cell wall thickens, and the collagen content in muscle is dozens of times higher than that of ordinary grass carp, so it will become brittle.

Brittle method:

1. The water quality and feed requirements for raising Anhui crisp meat are as follows:

1) requires fresh water and sufficient dissolved oxygen, and the dissolved oxygen should be no less than 5mg per liter. Use reservoirs, mountains and fresh water. In the fast-flowing pool water, fish swim quickly, which makes muscles exercise frequently, reduces fat accumulation and increases muscle toughness.

2)? The feed for raising crispy pomfret is mainly expensive natural northeast broad beans. Broad beans do not need to be crushed, and the whole material is soaked in clear water for more than one day and night to make them soft and swollen, which is convenient for grass carp to eat and digest.

2. Management requirements:

1) Fitness

Crispy pomfret is willful and a fitness madman in the fishing industry. In addition to feeding enough broad beans for daily use, it is also necessary to ensure that they have enough exercise space and a lot of exercise to make the meat brittle. The water temperature should not be too high, but must be lower than 25 degrees. Otherwise, even if you support them with broad beans, the fish will not be crisp.

They like to wash the tide, like to jump, and have high requirements for the water quality they grow. The depth of the aquaculture pond must exceed 2.5 meters. First of all, give the fish enough swimming space. Second, the water temperature can be kept below 20℃, because crispy pomfret is naturally afraid of heat and likes cold.

2) Out of the pond to reduce fat

Even if you swim and jump every day, you will inevitably have a fat figure. If you don't lose weight, it will lead to a large number of deaths in long-distance transportation. The so-called slimming means stopping feeding 1 month before long-distance transportation. The purpose is to remove garbage from fish intestines and consume body fat. The quality of fish with garbage removed is better, otherwise the fish will be excreted on the way, leading to infection and death, and the fish that barely survive will make people feel greasy and disgusting.
