To enable the best management policies to be implemented it is important to have a good knowledge of what fish stocks are present. For this we have the research department, whose duty is to conduct stock surveys and also to conduct research into the damage fishing equipment may be causing to both the fish and the environment. To help us in this role we have the research vessel
Three Counties and the RIB Runner. Because of the importance of the shellfish stocks in the Wash, which in 2006 were worth a first-sale value of £5 million, much of Three Counties' time is spent in the Wash surveying the stocks of cockles and mussels. There is also a reef-building worm,
Sabellaria spinulosa, present in the Wash that is of environmental importance. Time is spent, therefore, using electronic equipment to map the location of these reef features, so that they can be protected from fishing activities.
The research department uses a variety of equipment including
Grabs, Dredges, Beam Trawls, Underwater Cameras, Remotely Operated Vehicals (ROV), plus electronic equipment such as Echo Sounders, Geographical Positioning Systems and Roxann Acoustic Ground Discrimination Systems. Even with all of this equipment, however, much of the time is still spent walking on the sandbanks and mudflats at low tide when it is possible to see first hand the shellfish stocks.
