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

Embodiment 1

[0047] The present embodiment provides a method for transporting sea-land relay shellfish seedlings, comprising the following steps:

[0048] Step 1: Load healthy scallop seedlings with a shell length of 5-10 mm in the transport net bag 16 of the transport rack 1, and the quantity of scallop seedlings in each transport net bag 16 depends on the specifications of the scallop seedlings, preferably, no more than each transport net bag 16. 5% of net bag 16 volumes, and the transport frame 1 that is fixed with transport net bag 16 is placed in seedling pond and cultivated for 2 days, during the cultivation, feeds fresh and alive unicellular algae (chaetoceros, golden algae, flat algae etc.) And EM bacteria, unicellular algae each feeding amount is 1.0-2.0×10 4 pcs / ml, the dosage of EM bacteria is 1g / m each time 3 , stop feeding fresh single-cell algae one day before transportation, and continue to feed EM bacteria, and the amount of EM bacteria is 1g / m each time 3 ;

Abstract

The invention discloses a method for transporting shellfish by land-sea relay, and relates to the field of transporting shellfish. The required shellfish; add seawater to the land transportation container, transfer the transport rack carrying shellfish that meet the transportation requirements to the interior of the land transport device; fill the live water tank of the marine device with filtered seawater, and transfer the transport rack to the live water tank, Turn on the second oxygen supply device, and adjust the water control panel so that the water control panel is always below the filtered seawater level inside the live water tank to maintain the calm water body inside the live water tank. The land-sea relay shell seedling transportation method provided by the present application can transport shell seedlings for a long time and long distance, and improve the survival rate of shell seedlings.

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 ...
