Portable transportation device and transportation method for marsupenaeus japonicus sea-caught seed shrimps

Abstract

The invention discloses a portable transportation device and a transportation method for marsupenaeus japonicus sea-caught seed shrimps. The device is characterized by comprising a constant-temperature box body, the interior of the constant-temperature box body is divided into three cavities, namely, a shrimp storage chamber, an ice storage chamber and an equipment chamber, shrimp grids for storing seed shrimps are arranged in the shrimp storage chamber; a refrigerant is placed in the ice storage chamber; a controller is arranged in equipment room, a water filtering system for circularly filtering water in the shrimp storage chamber and an oxygen supply system for supplying oxygen to the shrimp storage chamber are arranged between the equipment chamber and the shrimp storage chamber; the ice storage chamber is connected with an oxygen supply system through a pipeline; the temperature control system is electrically connected with the controller; the temperature control system is used for detecting the water temperature in the shrimp storage chamber and controlling the pipelines to be connected or disconnected according to the water temperature. The device has the advantages that theconstant temperature can be kept all the time, the operation frequency during seed shrimp transportation is reduced, the emergency response of seed shrimps during high temperature is reduced, the survival rate of the seed shrimps is increased, and the life vitality of the seed shrimps is guaranteed.

Description

technical field [0001] The invention relates to the field of aquatic product transportation, in particular to a portable transportation device and a transportation method of Penaeus japonicus sea-caught seedling shrimp. Background technique [0002] Due to overfishing and the destruction of the ecological environment, the resources of Penaeus japonicus have declined seriously. The number of sea-caught shrimp is scarce, and the survival rate of transportation is low. After sea-catch, it is mainly used for offspring reproduction. Therefore, it is necessary to fully guarantee its vitality during transportation. The transport requirements are particularly high during periods of high temperature. [0003] During the high temperature period, the existing methods of transportation for sea-caught species of Penaeus japonicus mainly include: car oxygenation transportation at room temperature, running water boat transportation, insulated running water truck transportation, nylon bag o...

Problems solved by technology

[0005] However, the above-mentioned transportation method still has the following defects for the sea-caught breeding shrimp of Penaeus japonicus: there is no cooling measure for the car oxygenation transportation method at normal temperature, and the higher water temperature has stronger activity ability of the breeding shrimp, which will lead to an increase in the mortality of the breeding shrimp; The live water boat transportation method does not affect the survival rate of the shrimp species during the live water transportation, but it needs to be connected to the shore for oxygenated transportation, which will affect the survival rate during the connection operation and transportation, and the transportation cost of the live water boat is high, so it is not suitable for small and medium-sized Enterprises; the method of transporting by heat-insulating running water vehicles also requires simple water tanks for temporary maintenance, and this method requires the use of existing large-scale heat-insulated box cars, which are large in size and high in transportation costs. They cannot directly reach the wharf with narrow roads and are inconvenient to operate. It is not widely used; if the nylon bag oxygenation transportation method is used, it is necessary to carry pure oxygen oxygen cylinders for on-site oxygenation and packaging, which has potential safety hazards. The oxygenation bag is difficult to cool down and keep warm, the shipping density is low, and the workload is heavy.

To sum up, the existing transportation method requires a simple tank for temporary storage after the catch is started, and it needs to be transported for transportation after landing. In the process, the emergency response frequency of the shrimp species is likely to be aggravated, resulting in an increase in mortality and a decrease in vitality, which is not conducive to reproduction
