The world's first 150,000-deadweight tonnage (DWT) smart aquaculture vessel Guoxin 2-1, a floating fish farm, is under construction in Qingdao City of east China's Shandong Province, and set to be operational in 2025.
The mega vessel measures 245 meters in length and 45 meters in width. It has 15 breeding cabins, each larger than two standard swimming pools. As a sister ship of "Guoxin 1", "Guoxin 2-1" has carried out more than 160 optimizations and innovations in terms of functional layout and new energy utilization.
Guoxin 1 has sailed for nearly 14,000 nautical miles to the Yellow Sea, East China Sea and South China Sea where different fish can be cultivated in their ideal temperatures and produced 2,700 tons of yellow croakers since its launch in May 2022.
"While retaining the hoisting method, we have employed an approach of side entry to send fish fry into the cabin. Holes are added on ship's side so that the fish fry can be directly transported to the breeding cabins, which greatly improves the efficiency and also reduces the damage rate," said Tian Neidong, a project director of Guoxin China Shipbuilding Qingdao Marine Technology.
In order to realize intelligent fish farming, the tanks are centrally controlled. Operations on board the ship are monitored with underwater cameras, sensors and a self-feeding system, as well as connectivity with the company's shore-based offices to monitor the fish.
The fish rearing density in the tanks is four to six times higher than in traditional aquaculture cages and the aquaculture cycle is shortened by 30 percent. In addition, the fish survival rate and the rate of weight gain are also increased.
"We have installed more than 2,000 sensors in various areas of the ship, which can transmit different data such as water temperature, water quality, and oxygen content in the breeding cabins to the monitoring room in real time, and then transmit it to the shore-based monitoring center through the ship-shore integrated system, realizing the interconnection between the aquaculture vessels and the land, and among the aquaculture ships," said Tian.

Iran on Tuesday warned it would deliver a stern response to any new aggression, after U.S. President Donald Trump ordering preparations for a prolonged naval blockade of the country.
Trump has instructed his administration to prepare for an extended blockade of Iran as the ceasefire remains in place amid stalled talks, The Wall Street Journal reported on Tuesday, citing U.S. officials.
In recent meetings, including a Monday discussion with top security officials in the White House, Trump opted to continue squeezing Iran's economy and oil exports by preventing shipping to and from its ports, said the report.
The president assessed that the blockade, "a high-risk bid" to compel Tehran's nuclear capitulation, carries less risk than other options -- resume bombing or walk away from the conflict, the officials were quoted as saying.
Iranian government spokesperson Fatemeh Mohajerani stated the same day that Tehran has completed "all necessary arrangements" to counter the U.S. naval blockade.
She noted that Iran's primary strategy focuses on maximizing its geographical advantages through effective tactical maneuvers.
Also on Tuesday, Iranian army spokesman Mohammad Akraminia declared that the military considers the current situation a state of war.
Akraminia added that Iran has fully updated its target lists and operational equipment, promising a "stern response" to any further aggression.
Mujtaba Ferdosipour, head of Iran's Interests Section in Cairo, told the IRNA news agency on Wednesday that U.S. attempts to force unilateral demands through a naval blockade are ineffective. He stressed that Iran's extensive land borders with neighboring countries provide viable alternatives to bypass the maritime restrictions.
Ferdosipour reiterated that the Strait of Hormuz is closed only to vessels linked to Israel and the United States. He asserted that Iran has the right to manage security in the strait, maintaining that this position does not violate international conventions.
The envoy further stated that Iran does not trust the United States and has no desire for direct negotiations. He emphasized that Tehran can employ all available means to defend itself against attacks.
According to the latest data from the UN Trade and Development (UNCTAD), ship transits through the Strait of Hormuz have plummeted by 95.3 percent since Feb 27. The disruption has caused global food prices to rise by approximately six percent, while crude oil prices in European markets have surged by nearly 50 percent.
