Temporary culture system of marine fish by using circulating water

Abstract

The invention discloses a temporary culture system of marine fish by using circulating water. The temporary culture system comprises a marine-fish temporary culture pond, a fish unloading pond, a filtering pond, a water pump and a water pipe, wherein the marine-fish temporary culture pond, the fish unloading pond and the filtering pond are different in height, and are arranged in sequence from high to low; the marine-fish temporary culture pond, the fish unloading pond and the filtering pond are communicated by the water pipe; and the water pump is arranged above the water pipe connected with the marine-fish temporary culture pond and the filtering pond. The temporary culture system disclosed by the invention has the advantages that certain height differences are set among the marine-fish temporary culture pond, the fish unloading pond and the filtering pond, and a water-body filtering technology is applied, so that the cleanness and circulating use of the water for temporary culture are guaranteed. In addition, the temporary culture system disclosed by the invention has the characteristics of uniform oxygen supplying, high oxygen supplying rate, low temperature, low energy consumption, large temporary culture density and water-saving and energy-saving effects.

Description

technical field [0001] The invention relates to the field of fish farming, in particular to a circulating water temporary culture system for seawater fish. Background technique [0002] Fresh aquatic products are complete in color, aroma and taste, and have high nutritional value. However, after the fish is dead, the fish body is corrupted, the taste and nutritional value are reduced, and the safety is reduced. During transportation, many fish die due to lack of oxygen or adaptation to the environment. The freshness, preservation and long-distance transportation of aquatic products have always been a difficult problem, which is one of the main factors restricting the development of the aquatic industry. With China's entry into the WTO, this problem has become increasingly important. [0003] Since the reform and opening up, my country's aquatic industry has developed rapidly. In 1980, the total amount of aquatic products in my country was only 4.5 million tons, and the per...
