Flounder tramping Flounder tramping Flounder tramping is a traditional method of catching flounder or other flat fish by wading in shallow water and standing on them. This method of fishing was used in the coastal waters and river estuaries of South West Scotland for centuries. Once trapped the fish were often secured by impaling them on a leister before being bagged. A leister is the local name for a trident or three pronged long handled spear. Although traditional, the use of leisters to aid capture is no longer permitted (presumably for safety reasons). On the first Saturday each August, Palnackie, a small
Echo sounding Echo sounding Echo sounding is a type of sonar used to determine the depth of water by transmitting sound waves into water. The time interval between emission and return of a pulse is recorded, which is used to determine the depth of water along with the speed of sound in water at the time. This information is then typically used for navigation purposes or in order to obtain depths for charting purposes. Echo sounding can also refer to hydroacoustic "echo sounders" defined as active sound in water (sonar) used to study fish. Hydroacoustic assessments have traditionally employed mobile surveys from
