Many fabulous specimens were found over the years. By the 1930s, over-harvesting had severely depleted the oyster beds. The US government was forced to strictly regulate the harvest to prevent the oysters from becoming extinct, [citation needed] and the Mexican government banned all pearl harvesting from 1942 to 1963.

In 1910, two schooners from Koepang were reported to be at work harvesting beche-de-mer near the Walcott Inlet, within Collier Bay, after a "phantom ship" had been spotted off Cape Farquhar some days before. [12] By the 1930s, pearl luggers were mainly motorised and the use of mechanical air pumps allowed boats to use two divers.
