GLOW­ING bi­o­lu­mi­nes­cence has lured hun­dreds of peo­ple to Min­darie Ma­rina in re­cent days to ex­pe­ri­ence the phe­nom­ena.

The ap­pear­ance of the blue glow co­in­cided with a Health Depart­ment warn­ing about eat­ing fish, crabs and shell­fish caught in the ma­rina on Novem­ber 21.

Test­ing showed po­ten­tially toxic mi­cro­scopic al­gae at el­e­vated lev­els and the depart­ment warned that con­sum­ing the seafood could re­sult in par­a­lytic shell­fish poi­son­ing, which may cause mus­cu­lar paral­y­sis.

Min­darie res­i­dent Ian McDon­ald said it was the third year he had seen the bi­o­lu­mi­nes­cence and it had lasted about three weeks so far.

“I’ve never seen the place so busy,” he said.

Mr McDon­ald said peo­ple should not throw rocks or sticks into the wa­ter, as it cre­ated trip­ping haz­ards and af­fected the fish.

“Peo­ple have thrown rocks in the wa­ter and it spooked the fish,” he said.

How­ever, Mr McDon­ald said many peo­ple had taken the right ap­proach by us­ing buck­ets, pad­dles, fish­ing rods or sticks to stir up the glow.

“I’ve seen plenty of peo­ple there with a bucket,” he said. “That’s the best way to see it: scoop a bucket up and pour it back in.

“Peo­ple are get­ting sticks and stuff and just draw­ing in it and that’s fine as long as they don’t throw them in af­ter­wards.”

Mr McDon­ald threw a fish­ing net for Con­nolly res­i­dent Ian McCam­ley, who took pho­tos over the week­end be­tween 10pm and 1am.

“Most were taken by pour­ing wa­ter or drag­ging sticks through the wa­ter, so long ex­po­sures of around five to 10 sec­onds were needed to cap­ture all the ac­tion,” Mr McCam­ley said.

“It was great fun, and quite a chal­lenge, to take pho­tos of this mem­o­rable event.”
