CONCERN is growing for the future of the 130-strong colony of bottle-nosed dolphins in the Moray Firth.

The dolphins, which have attracted a great deal of interest in recent years, are becoming increasingly fragile, with experts warning of disease, under-nourishment and interference from speed boats and jet-skis.

The pod appears to be decreasing by around 6% a year and could be wiped out in less than 50 years if more is not done to protect them.

Pollution of the waters of the Moray Firth is also thought to be taking its toll of the dolphins and members of the public are asked to do their bit by using "green" detergents and cleaners, while fishing boats are asked to be careful with their waste.

Charlie Phillips of the North Kessock Centre is setting up a Highland branch of the Whale & Dolphin Conservation Society and is seeking members to help raise awareness of the problem. You can reach him on 731866.
