Live by the sea and rise to the sea. The ocean is the most distinctive urban feature and the greatest advantage of Qingdao. The ocean has endowed Qingdao with abundant resources, which highlights the city’s characteristics of livability, industry and tourism, and makes the marine aquaculture industry a well deserved characteristic industry in Qingdao.
From endangered species to large-scale aquaculture, from “sighing at the sea” to the R & D and application of intelligent aquaculture equipment – deep sea aquaculture can be said to be the epitome of Qingdao’s marine fishery moving towards “deep blue”. This can not be separated from the support of strong scientific research technology, and the updating and iteration of deep-sea aquaculture equipment is an important part of it.
In Qingdao, there is an enterprise that has been committed to the research and development and production of deep-sea aquaculture equipment for many years. Through unremitting technological innovation, it has developed an alloy mesh coat that is excellent in the aspects of anti marine biological adhesion, anti-corrosion and wind and wave resistance. This key technological breakthrough will also provide an important guarantee for Qingdao to “move towards deep blue”.
Specializing in the pain points of mariculture, successed after 5 years of research and development and 100 trial productions
It is understood that at present, a large number of cages used for marine aquaculture in China are concentrated in harbors. When the aquaculture density is higher than the environmental capacity of the sea area, and there is a lack of safe and effective methods for preventing parasitic organisms from attaching, the water flow in the cages is not smooth and the aquaculture environment is poor, which causes frequent fish diseases and the quality of cultured fish species.
In order to solve various pain points of net clothing in deep-sea aquaculture equipment, in 2017, Qingdao Haosail Machinery Co., Ltd. (hereinafter referred to as Haosail machinery) initiated the research and development of Haosail supper clean alloy fish net. After hundreds of tests, it successfully passed the inspection and certification of domestic and foreign authoritative testing institutions and institutes, and was officially put on the market in September 2021. This new supper clean alloy fish net can not only prevent the attachment of marine organisms, but also ensure the oxygen content in the water flow, so that the fish can always grow in a good water quality environment.
In addition, the enhanced anti adhesion ability also reduces the cleaning and maintenance costs of the net. With the multiple advantages of seawater corrosion resistance and long service life, the comprehensive cost of using this alloy net is only one-third of that of nylon net and ultra-high molecular weight net with the same volume.
It can be said that the alloy net developed by Haosail machinery has solved the market pain points in the field of marine aquaculture, such as easy attachment, low strength, short service life, high maintenance cost, poor wind and wave resistance performance of the cage, and low utilization rate of effective breeding space.
The dream chasing deep blue anti wind and wave scheme is “exclusively customized” for the deep sea
Once upon a time, offshore aquaculture not only satisfied the “food basket” of the people, but also brought serious pollution to the marine environment, accompanied by serious problems such as the depletion of offshore resources. It has become the consensus of Qingdao’s marine industry practitioners that marine aquaculture is marching into the deep sea.
“For this reason, in the changeable marine environment, a set of deep-sea aquaculture equipment that can adapt to changes in the environment and weather is particularly important.” Li Hong, general manager of Haosail Machinery Co., Ltd., told the reporter that deep-sea aquaculture involves high value-added fish, and some expensive fish fry have stricter requirements on the breeding environment. Therefore, it is necessary to customize the “growth environment” for different high value-added fish.
“For example, the lifting and suspended metal cage designed and developed by Haosail has an effective aquaculture space utilization rate of more than 95%, which is suitable for the needs of a variety of high value-added fish for different deep aquaculture environments.” Li Hong said that in the complete deep-sea aquaculture system, the new high-definition alloy mesh is not only a icing on the cake, but also a “finishing touch”. This is because the tensile strength of the alloy mesh wire is greater than 800 MPa, and the mesh made of it can resist the impact of level 12 typhoons, and truly erect a “iron wall” for the growth of fish.
The high profit return of deep-sea fish species and the cost reduction brought by the development of cage technology are the key to the large-scale development of Qingdao deep-sea aquaculture.
Haosail’s new supper clean alloy fish net not only solves the market pain points of easy attachment, low strength, short service life, high maintenance cost, poor wind and wave resistance of cage and low utilization rate of effective breeding space in the marine aquaculture field, but also reduces the cost through technical improvement. What is contained in it is the infinite potential given by scientific and technological innovation.
Qingdao needs more such “hard technology” to add fuel for “exploring the ocean and moving towards deep blue”.
