An industry watchdog says they've received no complaints about Marineland & their treatment of animals.

The Niagara Falls attraction has been a member of the Canadian Association of Zoos & Aquariums since 2007.  To hang on to accreditation, parks & zoos have to be examined every 5 years.

National Director of CAZA Bill Peters says Marineland last went under the microscope in August 2011 & no issues came up.

And despite allegations from ex-trainers of dirty water, understaffing & suffering animals, Peters tells 610 CKTB News no one has formally complained to CAZA.

Peters says those kind of complaints have in other cases triggered CAZA to dig deeper.  It could mean an extra visit from inspectors, or just a request from the accused member to address the allegations against them in writing.

Peters couldn't say if the pictures of Marineland & ex-employee accounts splashed across the front page of Wednesday's Toronto Star would be enough to have CAZA take another look at Marineland.

That's up to CAZA's Accreditation Commission.  The commission's chair is away for a family emergency.

While there are no government rules for sea mammal captivity in Canada, Peters says without CAZA-accreditation life becomes much tougher for zoos & aquariums.  In some cases, he says you can't bring in exotic animals without it.
