Ggeurengi
Ggeurengi are used in collecting hard clams from sandy tidal flats. The clams get caught on the bottom metal part as the fishermen drive ggeurengi over the tidal flat. This bottom part is the most essential part of ggeurengi, and it can be adjusted to suit the specific characteristics of getbatang and the depth of the mud that clams live in. It is a bit difficult to use, so there are not very many people who could use it properly in Daebu Island. The hard clam population is not very high in Daebu Island, so it does not seem to have been the main source of the fishermen’s income, but they are still sold for higher price, so a lot of fishermen envy those who can use ggeurengi (Fig. 11).
