An outstandingcontribution! QYSEA · FIFISH provides tremendous assistance in the field of coral biological research!

Recently, the FIFISH Underwater Robot has made big the news again!

In a collaborative project between QYSEA Technology and the globally-renowned Japanese company NTT Docomo, together with Professor Sato Noriyuki's team from the Okinawa Institute of Science and Technology, a breakthrough has been achieved in marine coral conservation. Their research findings were published in the Proceedings of the Royal Society, and the FIFISH Underwater Robot -accompanied by the research team- was interviewed by the popular Japanese entertainer Haruka Ayase, receiving countless praises!

#1: Shared Vision of Collaboration

NTT Docomo is currently one of the world's largest mobile communication companies and the largest mobile operator in Japan, with over 50 million users and a high level of influence in Asia and globally.

NTT Docomo also places great importance on marine environments and ecological health, actively combining industry, academia, and research in various marine initiatives.

In terms of protecting marine environments and conducting deep-sea explorations, QYSEA and NTT Docomo share a strong vision. Therefore, we collaborated with Professor Sato Noriyuki's team from the Okinawa Institute of Science and Technology to conduct coral ecological surveys and marine biological DNA sampling activities.

#2: Urgent Need to Protect Coral

For those living on land, it may be difficult to imagine the importance of coral to the oceans. Coral reefs are one of the most diverse ecosystems in the ocean, with abundant water content in the soil. Coral reefs are widely distributed in global seas, purify the marine environment, provide vegetation for the oceans, and protect all fish and marine ecosystems.

However, in recent years, some coral reefs have been polluted, and human activities have caused damage to coral reef colonies and their ecological environments. NTT Docomo staff engaged in coral protection in Okinawa expressed that it is easy to focus on the land but challenging to pay attention to the coral reefs beneath the sea. The whitening of corals is a sign of ecological deterioration, highlighting the urgent need for research and protection of coral reefs.


Against this backdrop, Professor Sato's team embarked on a series of scientific expeditions focused on coral reefs.

#3: QYSEA · FIFISH Demonstrating Its Abilities

Traditional coral reef research requires researchers to dive deep into the ocean to observe and record corals manually. This method is often time-consuming, labor-intensive, and limited by the depth and duration of dives. Moreover, it poses significant safety risks in extreme weather and environmental conditions.

In contrast, Professor Sato's team utilized the FIFISH W6 underwater robot equipped with two 500ml high-capacity sampling tools. The FIFISH W6, with its 4K dual cameras, Allowed for detailed observations of coral reefs. By collecting biological cortex, excreta, mucus, and other substances from the sea, DNA and eDNA were extracted for analysis, opening up new avenues for a comprehensive investigation of reef-building corals.

Furthermore, Professor Sato's team closely collaborated with the NTT Docomo team to explore deeper waters, ranging from 20 to 80 meters, where few had ventured before, to study coral reef systems.

NTT Docomo staff expressed that previously, they could only collect surface-level seawater samples. However, with the assistance of the robot, the diving depth more than doubled, and the diving duration increased by more than tenfold. The robot not only handled unexpected situations but also discovered unknown coral species and marine organisms such as thorny seastars.

During the deep-sea exploration mission, the FIFISH Underwater Robot completed its tasks, capturing clear video data and collecting numerous precious coral reef samples, providing technical assistance to coral reef exploration work.


This coral reef research expedition serves as a classic collaborative case in the field of marine scientific research for QYSEA Technology, marking an important milestone in the company's development.

QYSEA Technology will engage in extensive collaboration with more scientific research institutions, organizations, and universities to make greater contributions to human marine research endeavors!
