Jay Merriman-Mukoro, 43, was last seen swimming while on holiday with his wife Olivia in Barbados on April 20.
Colleagues paid tribute to him as a popular, respected friend and colleague. He had been working in Glasgow and had been in Barbados for a wedding. He had been working on a Commonwealth Games documentary.
His wife Olivia said she has spent "desperate nights of having images of him in my mind and thinking of him coming to harm, being in the water alone, cold, frightened".
