Before this year, the highest number of nests recorded was 11,321 in 2016—representing a full season of data.

Nairn attributes this year's success to two factors: Better nest protection efforts that began in the 1960s, as well as the increased use of "turtle excluder devices" in shrimp trawler nets.
