Chain restaurants like Denny’s, Long John Silver’s and Mcdonald’s use hoki–an ugly, bug-eyed fish found in the deep and cold waters of New Zealand–for their fish fillet sandwiches. But a New York Times piece said that this might change in the coming days.

The World Wide Fund has been recently alarmed because of the drops in hoki spawn that might have damaged the ecosystem. The organization is now fighting for a reduction in hoki fishing. Because of WWF advocacy, New Zealand ministry has cut the allowable fishing quota for hoki from 275,000 tons to only 100,000 tons. This means that Mcdo will have to cut down also in its usual consumption of 15 million pounds. The cut down in quota will result to Mcdo shrinking to only 11 million pounds of produced Filet-O-Fish per year.

According to Gary Johnson, Mcdonald’s senior director for global purchasing, the production could go up if the quota also goes up. Hopefully, they could solve the problem with the hoki fish or else we might have to bid farewell to our beloved Filet-O-Fish sandwiches.
