A kind of portable transport device and transport method of Penaeus japonicus sea-caught seedling shrimp

Abstract

The invention discloses a portable transport device and a transport method for prawn prawns caught in the sea, characterized in that the device includes a constant temperature box, and the interior of the constant temperature box is divided into three chambers: a shrimp storage room, an ice storage room and equipment In the shrimp storage room, there are shrimp grids for storing shrimp, in the ice storage room, there is a refrigerant, in the equipment room, there is a controller, and between the equipment room and the shrimp storage room, there is a device for circulating and filtering the water in the shrimp storage room. The water filtration system and the oxygen supply system used to supply oxygen to the shrimp storage room, the ice storage room is connected to the oxygen supply system through pipelines, and also includes a temperature control system electrically connected to the controller. The temperature control system uses It is used to detect the water temperature in the shrimp storage room and control the connection or closure of the pipeline according to the water temperature. The advantages are: it can always maintain a constant temperature, reduce the number of operations during the transportation of the shrimp, thereby reducing the emergency response of the shrimp during high temperature, and improving the survival rate of the shrimp. Ensure the vitality of the shrimp.

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
