Problems solved by technology

It fundamentally solves the problem that powdery feed is easy to lose nutrients, the flake feed has the same collapse time, and cannot meet the long-term feeding of sea cucumbers. Time, labor and material saving; the feed is comprehensive in nutrition, which can effectively promote the healthy and rapid growth of sea cucumbers

Embodiment 1

[0021] 1. Grind the feed materials to 100-200 meshes respectively, according to the formula: 30% sargassum powder, 10% sargassum powder, 35% kelp powder, 10% fish meal, 8% yeast powder, 4% shell powder, and 1 feed attractant. %, compound vitamin 2‰, and immune enhancer 2‰, weigh the raw materials and mix them;

[0022] 2. Add the binder sodium alginate 1.6% to the feed, put it in the mixer and stir it fully; the tablet press machine has multiple disc-shaped molds, and the mixed wet feed is extruded into a disc shape in the tablet press machine and passed through the conveyor belt. The adsorption effect of the molded disc-shaped granules is demoulded, and then dried to obtain a solid disc-shaped granule feed. The lower surface of the solid disc-shaped granule feed is a flat circle with a radius of R1.5 cm, and the upper surface is 0.5 to 0.6 cm high. The arc shape, that is, the height H of the dish-shaped pellet feed, such as figure 1 shown.

Embodiment 2

[0027] Mechanized feeding experiment of sea cucumber feed:

[0028] The mechanized feeding experiment of feed was carried out in the caisson of a japonicus breeding factory in Penglai. The experimental group was fed with disc-shaped pellet feed of sea cucumber, and the control group was fed with commercial flake feed of sea cucumber. Each treatment had three parallels.

[0029] Pellet feed is fed through a pneumatic bait feeding machine. The disc-shaped granule feed of sea cucumber in the experimental group has low resistance in the bait delivery pipeline and water, and is easy to disperse after power is applied, and can basically spread throughout the entire cage. , and the dispersion range in the cage is also small. Therefore, the dish-shaped pellet feed of sea cucumber is more suitable for various sea cucumber farming modes such as net cages, caissons, hanging cages, industrialization, and ponds, which are mechanized feeding methods.

Abstract

The invention discloses a stichopus japonicus dish-shaped granulated feed, which belongs to the technical field of aquatic feeds. The bottom side of the feed is planar circle-shaped, and the upper surface is arc-shaped. Due to the unique shape of the stichopus japonicus granule, the resistance of the granule in water and feed conveying pipelines is reduced, and the feed is applicable to a mechanical feeding mode; in addition, due to the advantages that the side part of the dish-shaped granulated feed is thin and easy to be floppy and the middle part is thick and long in shape-preserving time, the ingestion time of stichopus japonicus is prolonged; the feed is rich in nutrition, natural phycocolloid sodium alginate is high in adhesion capability, the components of the feed are not easy to be lost, small cultivation water pollution is caused, and the problem that a great deal of feed is wasted in stichopus japonicus cultivation modes such as net cage, caisson box, hung cage, factory and pond is solved; the food coefficient is about 1.5, the feed conversion rate is high, the cultivation cost is saved, and the cultivation benefits are increased.

Description

technical field [0001] The invention relates to the field of aquatic feed, in particular to a dish-shaped granular feed for sea cucumbers, which is used for breeding young and adult ginseng. Background technique [0002] Sea cucumber belongs to the phylum Echinodermata, class Holothuroidea, and genus Apostichopus. It is a traditional and precious seafood in my country. Sea cucumbers are mainly distributed along the coasts of China's Yellow Sea and Bohai Sea, eastern Russia, Japan and South Korea. There are more than 1,100 species of sea cucumbers in the world, and there are more than 100 species in China's sea area, of which more than 20 are edible. [0003] Entering the 21st century, sea cucumber breeding has developed rapidly, forming a breeding industry group with Shandong, Liaoning, and Hebei coastal areas as the main production areas, and extending to the coastal areas of Fujian and Zhejiang in the form of north-south relay. The continuous expansion of the scale of se...
