Description

A kind of indoor recirculating aquaculture facility of croaker

technical field

The utility model belongs to the field of aquaculture equipment, in particular to an indoor circulating aquaculture facility for croakers.

Background technique

Yellow croaker (Nibea albiflora) belongs to the Sciaenidae family and the genus Nibea. It is an economic fish in the middle and lower layers of warm water in the coastal waters. It is distributed in China, the Korean Peninsula and the southern coast of Japan. It is an important economic fish in my country. kind. It is rich in nutrition and delicious, and is welcomed by consumers. The market price in Wenzhou is stable at about 200 yuan/kg, and it is also favored by the majority of mariculture practitioners.

Research on yellow croaker has been reported for a long time. As early as the late 1950s, the Institute of Zoology, Chinese Academy of Sciences conducted a hatching test of yellow croaker fertilized eggs; in 1974, Japanese scholar Tian Beiche studied the early life of croaker Shi; Lei Jilin et al. (1981), Yu Fangping (2005) conducted a preliminary study on the morphological characteristics of croaker embryos, larvae and juveniles; Sun Zhong et al., 2005), industrial seedling cultivation (Lei Jilin et al., 1992), cage culture (Cai Houcai et al., 2000; Liu Qiaoling, 2009), nutrition and feed (Jin Yuhua, 2014), disease prevention and control (Ma Aimin et al., 2009; Zhang Saile et al., 2012) and other aspects have been studied. In recent years, many scholars have carried out research on the germplasm resources of croaker. Japanese scholars have carried out isozyme analysis on the population genetic structure of croaker from the coast of Japan and the East my country Sea (Menezes et al, 1990); Chinese scholar Han Zhiqiang et al. (2006, 2009) conducted AFLP analysis and isoenzyme analysis on the genetic diversity and population genetic structure of the yellow croaker population, respectively. Han Bing et al. (2007) conducted a comparative study on the morphology of yellow croaker populations and monkfish populations. The above studies have laid a good foundation for the protection and utilization of yellow croaker germplasm resources, artificial breeding and the development of aquaculture industry.

At present, the artificial breeding technology of yellow croaker has made a breakthrough. In Zhejiang, croaker is mainly cultured in sea cages and seawater ponds. The breeding technology has also made progress and gradually improved, especially in recent years in shellfish pond culture. Medium and low-density polyculture of yellow croaker can reach half a catty in the same year, and the growth is significantly faster than that of seawater cage culture. However, there are also some problems in pond culture. The water temperature in seawater ponds in Zhejiang Province is 2 degrees lower than that of sea cages in winter, reaching 6 degrees or lower. Generally, yellow croakers that can survive the winter in seawater cages can survive in seawater enclosures. It is difficult to survive the winter in the pond. In addition, most of the seawater ponds in Zhejiang Province are multi-species polyculture ecological breeding models such as shellfish, shrimp, and crabs. Yellow croaker is a polyculture species of fish in the ponds, and the seawater ponds generally need to clear the ponds every year. It is difficult to take into account the whole process of croaker breeding and sales in the pond culture mainly of shellfish, shrimp and crab. It is necessary to develop indoor breeding equipment for yellow croaker to carry out relay farming of croaker, to solve the problems of continuing to breed to reach the best commercial fish specifications, wintering safely, and keeping alive for sale.

This design can realize the function of rising water level and automatic flow, that is, the function of controlling the height of the water level.

Further, the water treatment tank is divided into four compartments. The culture water returned from the breeding tank passes through the sewer pipe and finally passes through the submersible ultraviolet disinfection lamp and then returns to the first compartment of the water treatment tank. The first compartment is filter cotton, Biochemical ball, coral sand; the bottom of the first grid and the second grid are connected, the second grid is used to grow large algae, and the bottom of the second grid is equipped with a glass partition and 3 diameters are made at the middle and lower position of the glass partition near the rear end of the water treatment tank 3 holes of 5cm connect the second and third compartments of the water treatment tank; the third compartment breeds large algae; the fourth compartment communicates with the third compartment and places a circulating water pump at the bottom; the first compartment physically filters and biochemically aquaculture water Filtration, the second and third compartments are used for plant filtration treatment of large algae. This kind of physical filtration combined with biological purification makes the aquaculture water fully purified and basically close to natural seawater.

Further, an indoor circulating aquaculture facility for yellow croaker is provided with a heating barrel, and circulating water, a heating rod and a thermometer are arranged in the heating barrel, and the heating barrel is connected with a hot water pump, and the hot water pump is connected with a curved circulation pipe, and the circulation pipe The bent part is inserted into the breeding tank, and the end of the circulation pipe is connected to the heating tank, so that the heating mode can be turned on in the particularly cold winter. Generally, it only needs to be heated to 30 degrees. The heat exchange between the hot water at 30 degrees and the breeding water can improve the breeding water. Temperature but no damage to farmed fish.

Further, the breeding tank is connected with the upper water pipeline and the lower water pipeline through a solenoid valve, and the solenoid valve is controlled by PLC so that the control of water flow can be fully digitalized and intelligent. PLC indirectly controls the submersible ultraviolet disinfection lamp, water pump, heating Tubes and hot water pumps, digitization and intelligence are the future development trends.
