Marineland says the Canadian Association of Zoos and Aquariums has found no "major issues" at the Niagara Falls, Ont., facility.

In a release issued late Thursday, the amusement park says experts from CAZA and the Ontario Society for the Prevention of Cruelty to Animals conducted a joint inspection.

This follows a series of published reports in which former Marineland staff alleged animals were not being properly cared for.

Dr. June Mergl, head of veterinary services at Marineland, said the allegations were without context, and that maintaining the welfare of the animals is a "balancing act."

Marineland says the CAZA experts noted there are "some eye issues in a few animals," but most are related to old age and all of these animals are under veterinary care.

Marineland is home to a variety of creatures, including beluga whales, dolphins and orcas.
