Latest coelacanth discovery!

Coelacanth finds in several locations in Africa in the past three weeks have kept scientists and conservationists on the hop in a bid to save specimens for research into this ancient fish.

Earlier this month a coelacanth was caught off southern Tanzania at Songa Mnara Island, followed by a catch off Moheli in the Comoros and then just a day later, another in Hahaya, north of Grand Comoro.

The finds extend the known habitat range of this fish. Coelacanths have never been found at Moheli and the only previous capture off Tanzania was an unconfirmed one at Mafia Island.

The fish found in Tanzania was caught by a local fishermen in a net in just 100m depth of water according to South African James Taylor. Taylor was visiting the island when he recognized the fish amongst many on the island left out to sundry. The fish had already been cut with all its insides thrown away. Mr Rumisha, manager of the Marine Parks and Reserves Tanzania and colleague, Prof. Bwathondi positively identified the fish and worked around the clock to try and preserve the specimen. According to Taylor the fish was 132cm and without its insides weighed 22kg.

The coelacanth finds follow almost immediately the NEPAD research and reconnaissance visit of the African Coelacanth Ecosystem Programme to Mozambique, Tanzania, Comoros and Madagascar. The discoveries in those areas are thus prompting scientists, including ACEP project manager, Dr Tony Ribbink, to speculate whether the finds are coincidence, a response to heightened awareness, or simply that the discoveries are now reported to the ACEP instead of going unrecorded.

Coelacanth expert Robin Stobbs agrees, "Yes, I know we're going to see them [coelacanths] popping up all over the western Indian Ocean now that the fish itself is becoming better known and as fishing habits, techniques and equipment change."

"What is clear is that in no instance were the catches due to increased effort or specific targeting of coelacanths," says Ribbink.

The discovery of coelacanths in the Greater St Lucia Wetland Park in South Africa at the end of 2000 by recreational divers, Pieter Venter and team, catalysed the development of the multinational African Coelacanth Ecosystem Programme. The programme was initiated in March 2002 with a successful expedition using the FRS Algoa and the German submersible Jago and now includes several African countries. Bwathondi and Rumisha who collected the coelacanth found off Tanzania are both with the Tanzanian Management committee of ACEP.

The coelacanth has a long history in Southern Africa. It became known to science in 1938 thanks to Capt. Hendrik Goosen, Majorie Courtenay Latimer and Prof JLB Smith. Since that eventful find, coelacanths have been found in several locations off the western Indian Ocean. No doubt this is just the beginning.
