Voyage Data Recorder Set up by NCKU for Fishing Research
TAINAN, Taiwan --(Business Wire)--
A Voyage Data Recorder (VDR), a small black box with data recording
system designed for fishing vessels mainly had played a crucial role in
exposing Philippines's untrue accusation of Taiwanese fishermen crossing
the border in the incident of Fishing Vessel Guang-Da-Shin No. 28 that
occurred on May 9. The VDR was developed by Chung-Hung Lin, an associate
professor of the Department of Systems and Naval Mechatronic Engineering
at National Cheng Kung University (NCKU), southern Taiwan.
Commissioned by the Fisheries Agency in 2005, Lin is the designer of the
data log with which Taiwanese fishing boats have been equipped for many
Lin said, when linked to the satellite antenna, the VDR incorporated
with GPS can locate a fishing vessel's position and the data is rnewed
every three minutes. It is "very reliable and accurate," he added.
No matter where the fishing vessel heads or how fast it goes, the VDR
keeps records of the time and the longitude and the latitude of the
ship, explained Lin.
He also said, the software like map system, information system and data
base is applied to draw out useful data to investigate the happenings
along the voyage.
The original purpose of setting up VDR is for setting quota of
preferentially priced oil for fishermen, added Lin.
However, this system can not only record the locations of fishing
vessels but find the areas of major fishery harvests, which help the
management of fishery resources.
"If you record all the data where fishes are being caught, there can be
formed a diagram."
"Before having the VDR, we didn't know for sure where the fishing
vessels were; however, after setting up the VDR, we can know where fish
are caught and the amounts of our harvests. It's really important
information for our management of resources," said Lin.
Lin currently is cooperating with other scholars, hoping to add a sensor
on the VDR and then great amounts of data about sea temperature, season,
and harvest can be collected and analyzed.
VDR can not only offer information for the government in negotiation
with neighboring countries about borderline of enforcement but also map
out fishing areas, forecasting the conditions of fishing resources.
