Formula and preparing method of ecological feed for stereoscopic breeding in sea cucumber, prawn and nettlefish pond

Abstract

The invention relates to the technical field of feed processing, in particular to a formula and preparing method of an ecological feed for stereoscopic breeding in a sea cucumber, prawn and nettlefishpond. The feed is prepared from 5-25 parts of defatted fish meal, 2-12 parts of scallop skirt, 10-30 parts of corn straw powder, 10-40 parts of bean pulp, 1-10 parts of shrimp head meal, 10-30 partsof wheat meal, 1-10 parts of oyster shell powder, 1-10 parts of a probiotics powder leavening agent, 1-5 parts of a vitamin mixture, 1-5 parts of a mineral mixture, 1-3 parts of monocalcium phosphateand 10-40 parts of water. The feed prepared through the formula and preparing method is high in nutrient transmission efficiency; the feed can be used for rich water, the digestion and absorption rateof the feed is increased compared with a traditional feed, the feed has a substrate improving function, and the respiratory burst, phenol oxidase, superoxide dismutase and catalase in prawn immune indexes are improved.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to a formula of ecological feed for three-dimensional cultivation of sea cucumbers, prawns and jellyfish in ponds and a preparation method thereof. Background technique [0002] With the shrinking of the breeding space, the price of pond rent is increasing day by day, and the benefits of monoculture are not as impressive as before. At present, in northern China, soil pond culture is the main culture mode, mainly using three-dimensional mixed culture technology, among which three-dimensional culture of sea cucumber-prawn-jellyfish is an important culture mode in Yingkou and Dandong, Liaoning. Among them, sea cucumbers live in the bottom layer of ponds, prawns live in the middle and upper layers of pond waters, and jellyfish mainly live in the upper layers of waters. The main problems faced by three-dimensional farming are as follows: (1) Insufficient bait, which is because p...

Problems solved by technology

The main problems faced by three-dimensional farming are as follows: (1) Insufficient bait, which is because prawns and jellyfish mainly use algae and zooplankton in the water as bait, and the bait in the water body is difficult to continuously supply prawns and jellyfish to eat; (2) The bottom quality is poor , especially in summer, because sea cucumbers are in a dormant state and cannot eat the feces of prawns and jellyfish, resulting in a large amount of organic matter such as feces accumulating at the bottom of the pond, the contents of ammonia nitrogen, nitrite and hydrogen sulfide seriously exceed the standard, and the chemical oxygen demand continues to increase. It is easy to cause pond flooding caused by lack of oxygen in the pond

Feeding traditional feed will only increase the content of residual bait and feces at the bottom of the pond, and worsen the water quality, making it unsuitable for this farming model
