DALLAS - With aerial spraying starting Thursday night over north and east Dallas and the Park Cities, the Dallas Arboretum took precautions to protect fish in its four ponds.

The state, which hired the contractor for the EPA-approved spraying, said the pesticide, named Duet, "should not pose a risk for a healthy fish pond under sound environmental conditions."

The advisory said if there's concern, covering a pond as a precaution is the best approach. That's what the Arboretum decided to do.

There are koi, goldfish and mosquito-larvae-eating gambusia affinis in the garden ponds and Arboretum Horticulture Manager Jennifer Wang said they would rather be safe than sorry.

Wang said the Arboretum has never covered the ponds and had to innovate. So her staff bought 40 used ad banners, formerly pulled by planes, off the Internet.

They spent afternoon setting bamboo sticks over the water and aligning the non-porous banners on top of the bamboo so there's clearance above the water.

Wang said homeowners with ornamental fish ponds should do the same with tarps found in hardware stores to make sure fish will be protected.

The Arboretum is usually open from 6:00-10:00 p.m. on Thursdays for the featured Chihuly exhibit, but will be closed this Thursday night in advance of the spraying.
