          Forty six years after the "discovery" of coelacanths in the Comoro Islands, a new population was identified (1998) from at least two specimens caught off of North Sulawesi, Indonesia (And two others filmmed in 1999). Post doctoral research fellow, Dr. Mark Erdmann was on a honeymoon trip to the area in September, 1997, investigating a coral reef research site, when his wife, Arnaz, spotted a strange fish being wheeled into the fish market. They recognized the fish as a coelacanth and snapped a picture of it before it was sold. Believing the fish to be already known from Indonesia, the two later posted the picture on their honeymoon website, when Dr. E.K. Balon of the University of Guelph, a longtime coelacanth specialist, advised Mark to withdraw the picture and pursue further funding to confirm a second specimen.

           The National Geographic Society, Nature, and the Smithsonian Institute jumped on the bandwagon decreeing a news embargo which kept the coelacanth research community in the dark for another year. During this time a conservation program was set up by the Erdmann's. On July 30th, 1998 a second specimen was brought live to Dr. Erdmann. An attempt was made to keep the fish alive by dragging it through the water. This effort failed (see "divers attempt to revive dying coelacanth" under 'CONSERVATION'), however, this second specimen confirmed the find and led to the press release of September 24th, 1998, and subsequent world wide attention.

           North Sulawesi is some 10,000 kilometers from the Comoros with no apparent water current interactions. This population would appear to be completely isolated from the Comoran coelacanths whereas recent catches off of Madagascar and East Africa have not been eliminated as possible strays or satellite colonies. The Indonesian fishermen had long called their coelacanth "Rajah Laut" (King of the Sea). The observed specimens appear identical to the Comoran coelacanth, Latimeria chalumnae. Initial reports that they were brown, apparently resulted from the observation of dead specimens. DNA comparisons were performed and appear to confirm a new species of coelacanth which has been named Latimeria menadoensis. The Indonesian authorities declared their willingness to cooperate with several conservation initiatives, however, futher bycatches would be kept for research. It was ten years before the next catch was reported.

 

                       More Coelacanths Caught in Indonesia.

          After almost ten years, another coelacanth was caught in Indonesia.On May 19, 2007, a fisherman named Justinas Lahama and his son Delvi Lahama, caught a four foot, 110lb coelacanth off Manado Bay, North Sulawesi province. It lived for 17 hours in a quarantined pool. While this has been attempted several times in the Comoros with a similar survival rate, the May 19 resuscitation attempt is the first known effort in Indonesia. The fish was caught near the Bunaken National Marine Park, where fishing with shark nets has been banned for almost a decade. This catch made the international wire services! Below is a video of the chaos surrounding the catch posted on Youtube. In the beginning the fish is still alive!

Living Fossil "Coelacanth"

           Meanwhile, on September 17, 2009, the Indonesian newspaper KOMPAS reported that another coelacanth had been caught by fishermen on Wednesday 16 September 2009, around 06:00 in the Gangga waters, Likupang, North Sulawesi, Indonesia, about 90km from Manado. The coelacanth was still living when caught (with a net) and measured 114cm. Alex Masengi from Sam Ratulangi picked up the specimen for further investigation. (Rik Nulens)
