Residents Believe Dead Koi Could Be From Koi Farm in Hawaii Kai

HAWAII KAI (KHNL) -- Several Hawaii Kai residents say they believe they know where dozens of dead koi possibly came from.

And they say if that is the case, the person should be penalized.

The sight of dead koi scattered around Kuliouou Beach Park jogs the memories of several Hawaii Kai residents.

"Initially, I thought well, I don't know where those koi would come from," said Hawaii Kai resident Mark Elwell. "And then wait now, I've seen this koi facility, and I noticed the area and exactly where it was, so I put two and two together and figured that's it's probably, or possibly where those koi come from."

He's not the only one.

We got calls and emails, saying there's a house along the stream with koi ponds in the backyard.

We spot a house matching our viewers' description.

In the back, we find filter equipment for koi ponds.

Two huge pools.

And baby koi swimming in them.

"Definitely the proper authorities should look into this, whether that be the facility, or the whether the facility is further up the stream," said Elwell.

State officials say it not illegal to own a koi farm.

But it is illegal to dump them in the water.

If the koi were alive, it's a petty misdemeanor, punishable with a $250 fine for the first offense.

If the koi were dead, it'd be considered polluting the water -- just like sewage -- and fineable up to $25,000.

"Yeah, I really think they should be penalized," Elwell said.  "Either for the fact they're releasing koi into a salt environment, which he knows is not gonna survive. Or from the standpoint that they're littering Maunalua bay, which is really not nice at all, and really not cool at all."

The State Department of Land and Natural Resources is investigating, but needs more information.

If you have any, call the Department's pest hotline, and 643-pest.
