Description

Technical Field

[0001] This utility model belongs to the field of aquaculture technology, specifically relating to a land-sea transfer device for rainbow trout. Background Technology

[0002] Rainbow trout (Oncorhynchus mykiss) are native to cold-water rivers and lakes along the Pacific coast of North America. Their natural distribution has been influenced by recent environmental changes, resulting in several subspecies, some of which are now endangered in their native range. Rainbow trout are highly adaptable, able to survive in both freshwater and saltwater environments, with an optimal growth temperature of [missing information - likely a specific temperature range]. As an important salmonid fish, rainbow trout holds a significant position in global aquaculture due to its nutritional value, adaptability, and market potential, and is one of the most widely farmed cold-water economic fish species. Introduced to my country in the late 1950s, it is mainly farmed in cold-water regions of Qinghai, Xinjiang, Northeast China, and Southwest China. Annual rainbow trout production is only around 40,000 tons, far from meeting the domestic market demand of over 140,000 tons annually, indicating a vast potential for development in the salmon and trout farming industry. However, the development of the land-based salmon and trout industry is severely constrained by factors such as cold-water resources and land availability.

[0003] In recent years, with the discovery of cold water masses in my country's nearshore and deep-sea areas, and the gradual improvement of the "land-sea relay aquaculture model" for rainbow trout, the deep-sea salmon and trout aquaculture industry in my country has been rapidly developing. The land-sea relay aquaculture model for rainbow trout involves cultivating large-sized rainbow trout fry in freshwater, acclimatizing them to salinity, and then introducing them into seawater for adult cultivation. For the large-scale production of rainbow trout under this model, the fry, cultivated and acclimatized before being released into the sea, are gradually transferred to the ocean for further cultivation according to the deep-sea aquaculture plan and scale. During this transfer process, a large number of fish suffer damage and mortality. Therefore, how to effectively transfer rainbow trout fry to the sea is a major problem before the fry are released and one of the most important links in achieving the connection between land-sea relay freshwater and seawater aquaculture.

[0014] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. For clarity and brevity, not all features of the actual embodiments are described in the specification. However, it should be understood that many implementation-specific decisions must be made in the development of any such actual embodiment to achieve the developer's specific goals, such as complying with constraints related to the system and business, and these constraints may vary depending on the implementation. Furthermore, it should be understood that while development work can be very complex and time-consuming, such development work is merely a routine task for those skilled in the art who benefit from the disclosure of this invention.

[0015] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the device structure and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0016] To further understand the utility model's content, features, and effects, the following specific embodiments are provided, along with accompanying drawings. Figure 1 Detailed explanation is as follows:

[0017] A land-sea transport device for rainbow trout includes three fish-carrying boxes 1 installed side by side. Each fish-carrying box 1 has an external insulation layer 2. A circulating water pump 3 is installed at the bottom of each fish-carrying box 1. The circulating water pump 3 is connected to a solenoid valve 4 via a pipeline to control the water outlet 5. An overflow port 6 is provided on the upper side of each fish-carrying box 1. A temperature sensor 7, a pH sensor 8, and a dissolved oxygen sensor 9 are installed below the overflow port 6. A fish discharge port 10 with an electric valve is installed at the bottom of each fish-carrying box 1. The bottom of each fish-carrying box 1 has a 6.9-degree slope on both sides along its length towards the middle and a 5-degree slope on one end along its width towards the fish discharge port. A sewage outlet 11 is provided near the lowest point of the fish discharge port 10 with the electric valve. An observation window 12 and a hanging ring 13 are installed on the top of each fish-carrying box 1.

[0018] Furthermore, the fish-carrying box 1 is made of 316L stainless steel, and the volume of the fish-carrying box 1 is... .

[0019] Furthermore, the dimensions and specifications of the fish drain 10 .

[0020] Furthermore, the fish-carrying box 1 is transferred to a transport vehicle or transport ship via a lifting ring 13.

[0021] Furthermore, the volume of the rainbow trout land-sea transfer device is... Depending on the transportation distance and time, per m3 The water body can hold 50-100kg of live fish. The outer layer of the insulation layer is made of high-density insulation material. The material and thickness can be selected according to the transport temperature of the rainbow trout. The insulation layer provides excellent insulation for the internal water, ensuring the safety of the rainbow trout during transport. The fish discharge outlet is equipped with an electric valve that automatically controls the opening and closing of the large-diameter outlet. The outlet specifications are as follows. The fish outlet is smoothly connected to the fish tank and fish collection trough, and is equipped with an automatic interface switch for the external fish transport pipeline interface, ensuring a smooth connection and avoiding mechanical damage during fish transport.

[0022] Furthermore, the bottom of the fish tank is sloped, and the drain outlet is located at the lowest point of the fish discharge outlet. When the drain outlet discharges water, the water in the fish tank will automatically gather towards the fish discharge outlet, thus achieving the function of automatic sewage discharge. The bottom of the fish tank is designed with an automatic fish collection slope (fish welfare device). The two sides of the bottom in the length direction have a 6.9% slope towards the middle, and one end in the width direction has a 5% slope towards the fish discharge outlet. When fish are put into the fish tank through the fish discharge outlet, when the water in the tank reaches the bottom 1 / 3 position, the fish density will increase. At this time, the fish will first gather through the two sides of the bottom (2000mm long, 728mm wide, 6.9% slope) towards the fish trough in the middle position (2000mm long, 5% slope, 500mm wide fish collection trough). Through the automatic fish discharge slope at the bottom of the fish tank, the rainbow trout in the fish tank are continuously gathered to the fish discharge outlet. Through the fish transport pipeline, the fish flow with the water into the aquaculture net cage or the aquaculture pond of the aquaculture vessel. When the water level in the fish tank is low, an external water pump continuously replenishes the tank until all the live fish in the tank are automatically drained.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
