Land-sea relay spat transportation method

Abstract

The invention discloses a land-sea relay spat transportation method, and relates to the field of spat transportation. The land-sea relay spat transportation method comprises the following steps that spats are loaded into a transportation mesh bag of a transportation frame, and the transportation frame is put into a spat pool for cultivation; the spats meeting the transportation requirements are screened out; seawater is added into a land transportation container, and the transportation frame carrying the spats meeting the transportation requirements is transferred into a land transportation device; and a running water cabin of a marine transportation device is filled with filtered seawater, the transportation frame is transferred into the running water cabin, a second oxygen supply device is turned on, and a water control plate is adjusted to be located below the liquid level of the filtered seawater in the running water cabin all the time so as to keep a water body in the running water cabin calm. According to the land-sea relay spat transportation method, the spats can be transported for a long distance for a long time, and the survival rate of the spats is increased.

Description

technical field [0001] The invention relates to the technical field of scallop seedling transportation, in particular to a land-sea relay scallop seedling transportation method. Background technique [0002] In recent years, the water quality in the coastal areas has deteriorated seriously, and there are many diseases. It is difficult to cultivate and raise pearl oysters artificially. The far sea is far away from human activity areas, and has good water quality conditions required for the growth of pearl oysters, which is suitable for artificial breeding of pearl oysters. However, the primary problem of developing pearl oysters in the open sea is to break through the long-distance and long-distance transportation. The existing oxygenation packaging method, due to the limited space of the PE packaging bag and the small transportation volume, the oxygen filled is not enough to ensure the supply of long-distance long-distance transportation, which affects the survival rate of ...

AI Technical Summary

Problems solved by technology

Due to the limited space of the PE packaging bag and the small amount of transportation, the existing oxygen-filled packaging method does not fill enough oxygen to ensure the supply of long-distance transportation, which affects the survival rate of transportation; although low-temperature transportation can be successful in a short period of time, it cannot Long-term low-temperature transportation will cause irreversible damage to pearl oysters, which can lead to death; land transportation can be carried out by vans loaded with water buckets, and as the transportation time increases, feces, feces, etc. Mucus and spoilage can easily pollute the transport water, breed harmful bacteria, and reduce the dissolved oxygen in the water, resulting in the lack of oxygen and death of the transported scallop seedlings, which cannot be transported for a long time and long distances; affected by sea conditions during sea transportation, it is easy to cause the stress response of the scallop seedlings The occurrence of long-distance transport for a long time, the survival rate of shellfish seedlings is low
