The group, who completed a 40-hour course, graduated this week with the support of family and friends.
Senior Sergeant John Teaurima, Acting Sergeant Andrew Ngaiaere, and Constable Colin Matangaro were among the group of graduates from the Maritime Police Service.
Police Commissioner Maara Tetava presented certificates and congratulated the trio.
Fisheries officers Ruiruia David and Anika Hunter from the MMR Offshore Division were accompanied by MMR Secretary Ben Ponia and Offshore Division Director Tim Costelloe.
Costelloe said the course, held at the University of South Pacific, had been helpful for both the ministry and those who took part.
“With the increasing profile of Chinese vessels in fisheries in the region, we found there were communication issues with fishing boat captains and crew during at-sea boardings and in port inspections.
“The course was designed in consultation with MMR as a special purposes programme to teach Fisheries Officers and Maritime Police Officers skills around the language of fishing activity and compliance duties.
“We were greatly encouraged by the results our officers achieved in the short time and are looking to continue this project to better communicate with foreign fishing operators in day-to-day activities.” - SO/ Release
