The scientist-caretakers of aquatic creatures at Nha Trang Oceanography Institute

In addition to research, scientists must keep watch and take care of fish being bred at the Nha Trang Oceanography Institute in Khanh Hoa province.

The scientist-caretakers of aquatic creatures at Nha Trang Oceanography Institute

At 7am, Dang Tran Tu Tram, 42, from the breeding department of Nha Trang Oceanography Institute, walked around to examine the sea creature area. She observed the creatures and meticulously took notes in a diary about the status of the electricity and water systems, aeration lines, and the water pump going to the water filter tanks, as well as the state of sea creatures in the tanks. If she noticed any problem, she recorded a solution.

There are 40 aquariums with hundreds of sea creatures at the oceanography institute, from sharks, turtles and lobsters to seals. They need different kinds of food.

Food must be thoroughly prepared and processed in different sizes that fit each species. When feeding the fish, Tram and her co-workers need to find which fish eat more or less. It’s necessary to discover why the fish eats less food to design a specific treatment regime for them.

In 2003, Tram graduated from Nha Trang University, majoring in aquaculture, and then worked for a seafood facility in Binh Thuan. Four years later, she returned to NhaTrang to work at the Nha Trang Oceanography Institute. Her major tasks are taking care of and raising fish.

Having 15 years of experience, Tram said she has a special impression about sharks, especially black reef (Carcharhinus melanopterus) and white reef sharks (Triaenodon obesus). Each of them has specific habits. The former swims continuously and eats food on the surface of the water, while the latter swims less.

The sharks’ pregnancy period lasts 12-13 months. Breeders need to know their reproductive characteristics to create suitable conditions for them to undergo the pregnancy.

Tram said she still remembers how she delivered a shark in childbirth several years ago. The shark lived with other members of the flock, so Tram and her co-workers feared that the young fish may be eaten by bigger sharks.

At 10pm, the mother fish went into labor. After a while, each fry with the weight of 500-600 grams was born. Tram and her team immediately picked the fry up and put them into a specific tank. Only when they saw the fish staying safe could they could sigh with relief.

Fry need to be taken care of carefully and fed with finely chopped fresh cuttlefish to familiarize them with eating dead creatures. After six months of breeding, each fish weighs 7-10 kilogram and 1 meter long. They are then put into the same tanks with other fish.

Tram takes care of other fish, such as Synanceia, seahorse (Hippocampus sp.), Branchiostegus japonicas and Diagramma pictum. Each has specific habits, so it’s necessary to keep close watch and design suitable diets for them.

For example, the pterois volitans is being bred in a glass tank, 1.5 meters long, 70cm high and 50cm large, with miniatures and algae and moss. The fish species has many colors and is called ‘the princess of the sea’. It’s simple to care for the fish, but the work requires care because it has a sharp dorsal fin that is toxic.

Meanwhile, Nguyen Truong Tai, 27, a co-worker, remembers the first time when he dove under water to feed and bathe them. He had been working for several months by that time, but he was not familiar with the work.

“I felt sick when coming closer to the fish because of the fishy smell. However, I became familiar with the work and I like my job,” Tai said.

Tai graduated from Nha Trang University and has been working there since then. Every day, he has to monitor the health conditions of fish, feed them and treat them if they are sick. Every time when receiving new fish, he learns the habits of the fish and puts them into specific tanks for easier care. Sometimes he wears scuba equipment and dives to clean the aquariums. Sometimes he performs with the fish to entertain visitors.

Tran Thuy Anh, 45, who has been taking care of sea creatures for 27 years, said everyone needs to have diligence, meticulousness and passion to be able to work there. They have to examine the water regime, clean the tanks, and clear waste and the feed residue to ensure a safe environment for the fish.

In addition to the care and domestication of sea creatures, the institute has succeeded in organizing artificial reproduction of sea creatures such as Pterapogon kauderni and Actinia equine.

Tech unicorn VNG to list on UPCoM

Vietnamese tech giant VNG Corporation is finalizing its list of shareholders to prepare for a listing on the Unlisted Public Company Market (UPCoM) exchange.

Published

Towards this, it has asked shareholders to complete their transactions before 5 p.m. November 28. All further transactions will be delayed until its shares are up on the UPCoM, an exchange set up to encourage companies to list their stocks.

UPCoM is one of three bourses in Vietnam, of which the Ho Chi Minh Stock Exchange (HoSE) is the biggest with the highest criteria. It requires a company to post profits within the previous two years to list.

VNG, however, posted a loss of over VND70 billion last year.

The unicorn, a startup with a valuation of more than $1 billion, has also announced that its three foreign shareholders, Tenacious Bulldog Holdings Limited, Prosperous Prince Enterprises Limited and Gamevest PTE, have reduced their stakes to below 5% each.

Tenacious Bulldog and Prosperous Prince had a 28.46% stake in VNG, while Gamevest had an 8.14% stake.

The listing on UPCoM is an unexpected move by VNG, given that it had earlier announced plans to list on NASDAQ.

In the first nine months of the year, VNG posted losses of over VND764 billion.

Founded in 2004, VNG operates Zalo, a highly popular messaging and social network platform in Vietnam.

Vietnam to become a regional Digital Hub

Vietnam is aiming to become a Digital Hub, a place to transfer, connect, store and process data regional and world data.

Published

on

The Ministry of Information and Communications’ proposed information and communication infrastructure plan for the years 2021 to 2030 is to make Vietnam a “Digital Hub” where data from across the world may be transferred, connected, stored, and processed.

The term “Digital Hub” refers to a network of data storage facilities, cloud computing infrastructure, and Internet traffic exchanged by super developers, as well as global telecommunications, information technology, and digital content, which offer services in several nations and regions.

Vietnam has geographic advantages to become a regional digital hub, according to the Ministry of Information and Communications, including its location between Northeast Asia and Southeast Asia, close proximity to important and dynamic development centers in the region and the world, where many economies serve as growth engines, and its location on the trans-Asian road route established by the United Nations Economic and Social Commission for Asia and the Pacific in order to coordinate regional development.

Additionally, Vietnam is situated on the primary axis of the East-West Economic Corridor (EWEC), which connects the Pacific and Indian Oceans, offering tremendous potential for quick, economical, and efficient freight transit. 

The chance that Vietnam will emerge as the region’s digital hub is also demonstrated by the number of Internet users and, in particular, the data traffic that migrates to Vietnam. 

Statistics show that there are presently more than 72 million Internet users in Vietnam, with certain applications like Facebook having up to 75.6 million active users and accounts, and Zalo having more than 75.6 million active users, and 74.1 million active users, respectively.
