Problems solved by technology

[0003] There is no natural distribution of California sea cucumbers in my country, and artificial breeding has not yet been carried out. The products mainly rely on the import of dried sea cucumbers and high-pressure processed sea cucumbers. Due to the unsolved transportation problems, it is difficult for fresh and live products to enter the domestic market.

Embodiment 1

[0020] Diving in the Strait of Georgia, BC, Canada to collect natural California sea cucumbers, select healthy individuals, thick skin without trauma, and wet weights of 300-600g. After collection, filter sea cucumbers at a water temperature of 15°C for temporary storage, and wait for the sea cucumbers to empty their feces. , reduce the seawater temperature to below 10°C within 2-3 days.

[0021] Pre-clean the incubator and fresh-keeping box, perform disinfection and degreasing treatment. 4 hours before shipment, put the transport container and absorbent sponge into the cold storage to cool down.

[0022] The container for shipping sea cucumbers is a rectangular fresh-keeping box with a partition plate. The height of the fresh-keeping box is (5-6cm), and the horizontal width of the small compartments in the box is fixed (6-7cm). Adjust according to the body length of sea cucumber. The overall length of the fresh-keeping box has two specifications: 30-40cm and 60-70cm. The b...

Embodiment 2

[0025] The sea cucumbers transported in Example 1 were placed in a recirculating aquaculture system, and a probiotic combination (bacillus, saccharomyces, lactic acid bacteria, and actinomycetes were added in a ratio of 1:1:1:1) was used one week later, and the recirculation For aquaculture, stop adding the probiotic combination after 20 days, start feeding granular sea cucumber bait gradually, and change the water by 30%-50% every day. Sea cucumber bait consists of 40% sea mud, 30% sage powder, 10% diatom powder, 7% defatted fish meal, 10% oyster shell powder, 0.5% Chinese herbal medicine extract, 2% shrimp shell powder, 0.5% multivitamin. Chinese herbal medicines including rhubarb, coptis, scutellaria baicalensis, phellodendron, angelica, and isatidis (ratio 1:1:2:1:2:1), soaked in ethanol, ultrasonically broken, extracted with 90% ethanol under reflux, concentrated and dried into granules . The multivitamin can be a vitamin product commonly used in the field of aquatic fe...

Abstract

The invention provides a long-distance transportation method for California red sea cucumbers. Seawater temperature, pH and salinity selected by the method are obtained by means of long-term creative work testing; if the temperature is too high, when the sea cucumbers are stimulated in an adverse situation, autolytic enzyme activity is too high, autolysis risks are increased, and the death rate is increased. Probiotics selected in the method are dominant bacterial communities screened in the intestinal tracts of the sea cucumbers and stored genetic resources, water quality is purified, the intestinal tracts are optimized, and high-quality protein and amino acid are provided. Bait in the method is composed of large algae and micro-algae in a mixed mode, is more natural and can promote assimilation of the sea cucumbers; Chinese herb extract can improve immunity and restrain harmful micro-organisms.

Description

technical field [0001] The invention belongs to the technical field of fresh-keeping transportation of aquatic products, and in particular relates to a long-distance transportation method of California red ginseng. technical background [0002] California sea cucumber, also known as American red ginseng. Native to North America, it is distributed in natural seas from shallow water to 249 meters deep in the intertidal zone from California to Alaska. This species of sea cucumber is restricted fishing as an important economic species in British Columbia of Canada, Washington State and Alaska of the United States. It is large in size and rich in nutrition. [0003] There is no natural distribution of California sea cucumbers in my country, and artificial breeding has not yet been carried out. The products mainly rely on the import of dried sea cucumbers and high-pressure processed sea cucumbers. Due to the unsolved transportation problems, it is difficult for fresh and live pro...
