Description
Technical Field
The invention relates to the field of fish culture, in particular to a seawater fish circulating water temporary culture system.
Background
The fresh and live aquatic products have good color, smell and taste and higher nutritive value. However, after the fish dies, the fish bodies are rotten, the taste and the nutritional value are reduced, and the safety is reduced. During transport, many fish die because of oxygen deprivation or lack of environmental compliance. The preservation, the keeping alive and the remote transportation of aquatic products have always been a difficult problem, are one of the main factors restricting the development of the aquaculture industry, and are increasingly important with the addition of WTO in China.
The development of the aquaculture industry in China is rapid since the development of the aquaculture industry in China is opened, in 1980, the total amount of aquatic products in China is only 450 ten thousand tons, and the per capita aquatic product accounts for only 4.59 kg; in 2010, the total output of aquatic products in China reaches 5350 ten thousand tons, and the per-capita aquatic product accounts for more than 40kg, which is twice of the per-capita in the world (the per-capita in the world is only 20 kg). This enormous production and consumption objectively provides an important basis and condition for the development of the water product stream industry. Therefore, the development of the aquatic product circulation transportation industry has important background and significance.
The aquatic product is one of main favorite nutritional foods, and the fresh and alive transportation technology of the aquatic product is very important, so that the aquatic product is beneficial to consumption of the safe edible aquatic product. At present, the international recognized aquatic product cold chain and food safety processing control standard are adopted for global aquatic product trade and transaction, and before the aquatic product is produced, processed or stored, the international market can be entered through a hazard analysis key control point (HACCP) and health certification examination of the aquatic product cold chain.
The remote transportation of the fresh and live aquatic products mainly comprises two technical links of temporary culture (temporary culture) and distribution, wherein the purpose of the temporary culture is to reduce the activity of the fish, so that the fish can adapt to a high-density culture environment and prepare for the subsequent distribution. In a certain water space range, high-density temporary culture is realized, and three conditions must be met: low temperature, high efficiency dissolved oxygen supply system and good water quality. After the fresh and live aquatic products are temporarily cultured, the aquatic products can clear excrement and urine, strengthen muscles and improve meat quality and physique so as to adapt to a high-density, long-distance and long-time transportation environment, and the method is a necessary stage before the fresh and live aquatic products are transported. Therefore, temporary culture is an important link for improving the transportation survival rate, improving the vitality of aquatic products and keeping the meat quality delicious.

In this embodiment, the temporary seawater fish culture pond 1, the fish unloading pond 2 and the filtering pond 3 are provided with a certain height difference structure, the water to be purified flows into the fish unloading pond 2 and the filtering pond 3 from the temporary seawater fish culture pond 1 in sequence by using the gravity of water for filtering, and the filtered water is pumped into the temporary seawater fish culture pond 1 through the water pipe 5 by the water pump 4, so that the water in the temporary seawater fish culture pond 1 is recycled and cleaned, and water and energy are saved. In the working process of the water filtering pond for the temporary seawater fish culture pond 1, the water inlet valve is opened firstly, unfiltered water flows into the to-be-filtered tank 311 of the filtering pond body 31 through the water inlet 32 of the filtering pond, then the water flows into the to-be-filtered tank 311 through the filtering plate 34, the to-be-filtered tank 311 is filled with the filtering material 35, and the water passing through the filtering material 35 flows out from the water outlet 33 of the filtering pond.
