Embodiment 1

[0037] Using live water trucks to transport oblique grouper ( Epinephelus coioides ) juveniles, with a body length of 9 ± 0.7 cm, a treatment group and a control group were set up, with 3 parallel groups in each group, a total of 6 temporary storage buckets (volume 1 m 3 ), the density of temporary culture is 800 tails / barrel, the transportation is 12 hours, the temperature is maintained at 26±1℃, and the dissolved oxygen is maintained at ≥4.0mg / L by aeration of air stone. The juveniles of the treatment group were given 10 ppm teprenone and 200 ppm glucose dipping bath for 1 h before transportation. During transportation, 20-30 ppm ethyl m-aminobenzoate mesylate (MS-222) and 100 ppm glucose were added to the water body. The juveniles of the control group were placed in clean sea water for 1 h before transportation, and the operation was the same as that of the treatment group, and MS-222 and glucose were not added during transportation. After transportation, the two groups of...

Embodiment 2

[0040] Transporting red-spot grouper in oxygen-filled bags ( Epinephelus akaara ) juveniles, with a size of 6±1.2cm, set up a treatment group and a control group, 5 parallel groups in each group, a total of 10 bags (volume 15L), a temporary culture density of 50 fish / bag, transported for 8h, and the temperature was maintained at 26±1℃ during the period , sealed after one-time oxygenation. The juveniles of the treatment group were given a dipping bath of 10 ppm teprenone and 200 ppm glucose for 1 h before transportation. During the transportation, 20-30 ppm MS-222 and 150 ppm glucose were added to the water body. The juveniles in the control group were placed in clean sea water for 1 h before transportation, and the operation was the same as that in the treatment group, and MS-222 and glucose were not added during transportation. After transportation, the two groups of fish were placed in the same culture environment for 10 days, and the survival rate was recorded.

Abstract

The invention discloses a transport method of epinephelus juveniles. The transport method comprises the following steps: treatment before transport: utilizing seawater containing 10-15 ppm of teprenone and 150-250 ppm of glucose to perform medicated bath of epinephelus juveniles for 1.0-1.5 h; transport: adding a proper amount of an anesthetic and glucose with the final concentration of 100-150 ppm into seawater, controlling the temperature to be 25-27 DEG C, keeping dissolved oxygen to be not less than 4.0 mg / L, and transporting the epinephelus juveniles; stocking of juvenile fishes after transport: adjusting the temperature difference between transport water and water in a culture pond to be less than 2 DEG C before juvenile fishes enter the pond, and transferring juvenile fishes and water into the culture pond. The transport method of epinephelus juveniles can realize long-distance transport of epinephelus juveniles at the ordinary temperature, is high in survival rate of juvenile fishes and high in survival rate of culture, and ensures that epinephelus juveniles are strong in constitution, high in feeding intensity and low in probability of fish disease infection.

Description

technical field [0001] The invention relates to the technical field of aquaculture and transportation, in particular to a transportation method for juvenile grouper. Background technique [0002] Grouper, belonging to the order Perciformes, the body is long oval and slightly flattened. The mouth is large, with an auxiliary maxilla, and the teeth are finely pointed, and some are enlarged into canines. The body is covered with small ctenoid scales, sometimes buried under the skin. The dorsal and anal fins have well-developed spines, the caudal fin is round or concave, and the body color varies a lot, often brown or red, with stripes and spots, mostly warm-water large and medium-sized marine fish. [0003] Grouper is rich in nutrients, tender and white meat, similar to chicken, known as "sea chicken". Grouper is also a low-fat, high-protein, high-quality edible fish. It is promoted by Hong Kong and Macao as one of the four famous fish in China. [0004] In recent years, wit...
