Problems solved by technology

The main problems in the transportation process are: (1) There is food or metabolites in the intestinal tract of the fish that have not been discharged, which will be excreted into the water tank during transportation to deteriorate the water quality, resulting in hypoxia or poisoning; (2) There are no scales on the body surface of the sturgeon, Improper handling methods lead to mechanical damage on the body surface, burying hidden dangers for the growth of saprolegniasis in the future; (3) Improper recovery and handling after transportation to the destination, resulting in increased mortality

Embodiment Construction

[0017] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract), unless otherwise stated, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0019] 1. Sturgeon to be transported

[0020] Large sturgeon over 50kg.

[0021] 2. Sturgeon before transportation

[0022] Before transportation, put the sturgeon in the holding pond without food for 7-10 days, stretch the net twice, and adapt to it for 2 days when the water temperature drops to 9-12°C; The dosage of anesthetics for sturgeon is different. The water temperature in the transport tank is controlled at 9-12°C, the dissolved oxygen is 8mg / L, and the ...

Abstract

The invention discloses a large sturgeon transportation method. Before transportation, food and metabolite inside a sturgeon are emptied in a feed deprivation mode so that water can be effectively prevented from going bad in the transportation process, and accidents such as anoxia or poisoning inside the sturgeon body can be prevented; in the transportation process, the water temperature, oxygen dissolving rate and other index inside a water tank are adjust to meet the requirement, and water is changed every 6 h; after arriving at a destination, the water quality indexes of a culture pond are controlled to be consistent with those of the water tank, feed is not added in the temporary culture period, a proper quantity of a physical enhancing agent can be splashed, and the water in the cultural pond is gradually regulated to reach the indexes for long-term stocking. According to the large sturgeon transportation method, the sturgeon body is hoisted with a crane and cotton strips, collisions with a netting gear, culture pond walls and transportation water tank walls are avoided, mechanical damage to the body surface is relieved to the maximum, and saprolegniasis can be effectively prevented.

Description

technical field [0001] The invention relates to a method for transporting large sturgeon. Background technique [0002] At present, the survival rate of live fish transported for large sturgeon weighing more than 50kg is low, the physiological recovery period of the fish body is long after being transported to the destination, and skin bacterial infection occurs from time to time. The main problems in the transportation process are: (1) There is food or metabolites in the intestinal tract of the fish that have not been discharged, which will be excreted into the water tank during transportation to deteriorate the water quality, resulting in hypoxia or poisoning; (2) There are no scales on the body surface of the sturgeon, Improper handling methods lead to mechanical damage on the body surface, burying hidden dangers for the growth of Saprolegniasis in the future; (3) Improper recovery after transportation to the destination, resulting in increased mortality.
