As club members or their guests are likely to see this strange looking contraption in the river from early next season , I would like to explain its design and function in advance to possibly alleviate their natural curiosity.
The boards unusual plastic outriggers are necessary to prevent Otter turnover. Otters are by nature inquisitive creatures and like to investigate anything new in their territory and I have found from past experiments how easily they can turn a board over with obvious disatrous results if left that way.
I have used catamaran style boards in past experiments to prevent that, but their particular design would not be appropriate for this new style of research board ( only its principle ). I am sure the floats will prevent that happening.
The second photograph shows the underside and working part of the board. This is of a fairly delicate nature and consists of both microscope slides and thin wooden slides attached (Hopefully this now will be enough to prevent the desire to turn the board over to have a look ? )
Research into Baetis egg development has not ,as far as I am aware, been undertaken before. When the board is placed into the river early next year ,the hope is to attract LDO ( Baetis Rhodani ) egg laying spinners. It will however remain in the river throughout the summer for the possible collection of eggs from other members of the Baetis family.
Its aim is to establish if female spinners can be persuaded to lay eggs directly onto the glass slides for easier study ,to ascertain the durability of both the egg cases and their contents and also to confirm the incubation period of Baetis eggs etc.
As anything moored in a river is likely to catch floating weed or debris , it would be helpful to the project if this could be carefully removed by any member who may happen to wade past it, but hopefully now with this information, resist the temptation to turn the board over !
Much useful information is being gathered by ongoing fly research .Only recently have I learnt that BWO nymphs prefer a diet of Diatoms over Detritus. Maybe its the silica in the cell walls they enjoy ,who knows ? As Diatoms are present in both Epilithic and Epiphytic algae , some algae in the river does therefore bring its own particular benefits to feeding BWO nymphs.
The Club is a private one, founded in 1877, of approximately sixty-four members and six Town Rod subscribers. The Club’s waters consist of about 12 miles of wild brown trout & grayling fishing in the main River Frome, River Cerne and River Piddle, together with attendant carriers and side streams. The waters extend both above and below the town of Dorchester and the Club employs a part-time keeper.
Day Tickets are only available during the trout season and only on Tuesdays, Thursdays, Saturdays & Bank Holidays. (season 1st April – 14th October)
The Police have made it quite clear that poaching is a crime in progress covered by the 1968 Theft Act. Members should always call 999 to report it and not phone the keeper. Without a report the police will not be aware of the extent of a problem.
If possible note or photo vehicles.

Angling’s representative body, the Angling Trust, has a web site for anglers to record sightings of cormorants, goosanders and mergansers throughout the UK: www.cormorantwatch.com The site is easy to use and will gather vital data to help persuade government of the need for action to protect fisheries.
Invasive plants and animals can carry diseases that kill fish, block waterways and banks, interfering with fishing. They can be small and hard to spot, so are easily spread on damp clothing and equipment.
Protect the environment and fishing you enjoy, by keeping your kit free of invasive plants and animals.
