Project underway to protect new oyster species

The species was discovered in the Muar River, Malasia.

A project is getting underway to protect a new species of oyster discovered in Malaysia.

The new species, named Crassotrea (Magallana) saidii was identified in the Muar River during a collaboration between Queen’s University Belfast and Universiti Putra Malaysia.

While local fishermen have been aware of the species since the 1860s, it has not officially been named until now. Scientists were unconvinced that it differed from similar, more common species until they conducted a DNA test.

Dr Julia Sigwart from the School of Biological Sciences at Queen’s, a mollusc taxonomist, explained: “You can’t protect a species unless you know it exists through scientific validation, so it was important to make that distinction between it and any other species. 

“Official validation helps manage sustainability as scientists have more influence in encouraging the government and those who fish to protect it. It also ensures it has the best possible market value when it is sold as food.”

The new species has a relatively flat shell with brown scales and is around 120mm by 6mm in size. It is named after local businessman Md Saidi Bin Mohamed, who has been actively promoting research and conservation for the sustainability of the oyster since 2013. 

Concerned about whether local fishing practices in the Muar River were sustainable, he contacted the Universiti Putra Malaysia to see if they could help. Currently, the oyster lives in one tiny estuary and may be threatened by urbanisation.

Dr Sigwart said: “The population does seem stable, but it’s worrying that the only known occurrence of this species in the world exists in such a small area,  and we don’t know what is coming downstream that might threaten it.

“Tropical Southeast Asia is a very biodiverse region and this particular area of the Muar River is a rich and important habitat which can tell us a lot about climate protection and global biodiversity.”

Dr Leena Wong from Universiti Putra Malaysia, who sent the samples for DNA testing, added: “Our research group at Universiti Putra Malaysia, which has specialist local knowledge of biodiversity, is now working to develop aquaculture approaches to increase the Crassotrea (Magallana) saidii oyster population.

“We are pleased that experts from Queen’s University who have extensive knowledge of global biodiversity are supporting us in this important work.”

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
