YANTAI, China, August 14, 2020 /Xinhua=KYODO JBN/--

In China's coastal areas, there has been a saying that "the best Chinese ocean

ranches are in Shandong, while the best Shandong ocean ranches are in Yantai".

Yantai City, located on the coast of Bohai Sea in Shandong Province, is

vigorously accelerating its building of ocean ranches, and continuously

promoting the transformation and upgrading of ocean ranching. According to the

International Ocean Information Center, up to now, Yantai has 30 ocean ranches

at or above provincial level, of which 14 are at the national level, accounting

for one eighth of the total number in China; with its ocean ranches covering a

total area of over 700 km2, the city boasts an industrial chain of ocean

ranching with an annual output value of over CNY 50 billion.

Yantai has a sea area of 26,000 km2, nearly one tenth of which is suitable for

the construction of high-quality ocean ranches. In the 1970s and 1980s, Yantai,

as one of the first pilot areas in China, carried out experiments on artificial

reefs and conducted activities of stock enhancement and releasing of Chinese

prawns, becoming one of the cities in China that launched the construction of

ocean ranches and the city with the largest number of national-level ocean

ranches.

In recent years, Yantai has enhanced its level of technological innovation and

integrated application of ocean ranching, organized nearly 100 enterprises and

scientific research institutions to establish the Yantai Strategic Alliance for

Technological Innovation of Ocean Ranching Industry, and set up an investment

fund totaling CNY 1 billion for the development of marine industry to help

extend the industrial chain of ocean ranching. The fund is mainly used in ocean

ranching, marine engineering equipment, marine science and technology, seafood

farming, fresh product processing, etc. At the same time, they have been

integrating ranch data resources, improving the online monitoring of ocean

ecological environment, ocean ranch observation and the monitoring network of

marine economic operation, and building a big data platform for comprehensive

ocean management, so to achieve the "visual, measurable, controllable and

early-warning" management of ocean ranches.

In May last year, the "Changjing No.1" deep ocean intelligent net cage was put

into operation in Changdao, Yantai. "Changjing No.1" is the first domestic

deep-water sit-on-bottom intelligent net cage, which is researched and

developed by Yantai CIMC Raffles. It is 66m long, 66m wide, with an upper ring

height of 34m and an effective breeding water body of 64,000 m3, equivalent to

100 ordinary net cages. The net cage is equipped with automatic equipment for

baiting, underwater monitoring and net cleaning, as well as a sewage treatment

system, a desalination system and a solar power generation system. It is the

world's first deep-water sit-on-bottom aquaculture net cage and the first large

cage to achieve automatic net-lifting function.

In July of this year, "Genghai No.1", China's first large-scale complex

platform of intelligent ocean ranching, was put into operation in Yantai. It

has a total diameter of 80m and a total breeding volume of 30,897 m3,

equivalent to the water volume of 14 swimming pools of international standard,

and is composed of three identical and rotating sub-cages, like three petals

blooming at sea. "Genghai No. 1" has made multiple innovations in terms of the

movable sit-on-bottom structure, the new material netting, the intelligent

equipment, etc., and is expected to produce 150,000 kg of fishes and receive

50,000 tourists annually.

Relying on its ocean ranching platforms, Yantai has begun to explore the

building of a new model of recreational fishery development that combines

"ocean ranching + marine engineering equipment + tourism" and "leisure sea

fishing + yachting", to promote the deep integration of fishery with tourism

and sports industry. Last year, Yantai achieved an output value of CNY 5.1

billion in its recreational fishery industry, with a year-on-year increase of

13.5%.

Zhang Shuping, Secretary of Yantai Municipal Party Committee, said that the

city would continue to leverage its building of ocean ranches as the main

driver for the transformation and upgrading of marine fishery, and adhere to

the development path of scalable, engineering, intelligent and green ocean

ranches, in accordance with the principle of "ecology first, land and sea

integration, and sustainable use".
