Ukrit Satapoomin made his comment after the burial of a seven-metre whale shark on a beach at Koh Lanta.
The large whale shark died on the same weekend that a sick dolphin and three maimed turtles died as marine biologists at the Phuket centre tried to nurse them back to health.
Marine deaths and maimings have prompted debate about what needs to happen to preserve Phuket's coral reefs and beaches and the creatures that inhabit the waters around them.
The growth in the tourism industry - with more boats and garbage going into the sea - and the fishing industry are blamed for the perception that more marine creatures are now being needlessly killed or maimed.
The Director Of the Phuket Provincial Fisheries Office, Kawi Saranakhomkun, said today that trawlers were well aware of the 3000 metre protected zone around Thailand's coast and did not fish within it.
''Our members operate within the law and every year we hold meetings to remind the captains that they must release endangered animals caught in their nets.''
Khun Kawi said he believed that tourism did far more harm to the Phuket region's marine life than fishing.
''Our industry causes minor damage compared to plastic trash that chokes the animals to death,'' he said. ''There are also more tourist vessels operating within the 3000 metre protected zone than ever before.
''This inevitably leads to propellors hitting the turtles.''
Biological Centre Director Khun Ukrit believes that businesses and local administrations on Phuket have to first take care of all bad water before releasing it into the sea.
''Once that is done, the coastal environment will improve,'' he said. ''Fortunately, Phuket is blessed in some ways by having strong currents that provide some relief.''
He says there are strong economic arguments why the fishing industry needs to be preserved and efforts to change the approach needed to be carried out within those limitations.
''I hope to be able to hold some talks aimed at reducing the toll on marine life,'' he said. ''But there is only so much we can do because the laws are plain.''
More local politicians are using the word ''sustainability'' without necessarily being empowered to achieve it.
Phuketwan has suggested that a Phuket Beach Authority needs to be created to protected all beaches from the rapid damage occurring because of privatisation and pollution.
Meanwhile, the whale shark has been buried on a beach on Koh Lanta. Once the bones have been stripped clean, marine biologists hope to dig up the skeleton for display.
