In 1967, the Persian Department of Environment sent a team of scientists to study the ecology of Shahi Island. Various results of the study, which included the breeding habits of brine shrimp, were published by Javad Hashemi in the scientific journal, Persian Scientific Sokhan. A herd of Persian antelope and gazelle were introduced into the islands, some of which survive to the present day. The Persian leopards that were also introduced to check the number of these antelopes survived for years, going extinct sometime in the early 1980s.
