KONSTRUKSI GARUK UNTUK KELESTARIAN SUMBERDAYA KERANG
Abstract
AbstractDredge is known as cockle collector which is not selective to the shell size and its operation
damages the cockle’s resources. The objectives of this research were to obtain better dredge
construction which was more productive and selective to the cockle size. The end of the
teeth was bent 30o to increase number of the catch. Separator was used to make the dredge
become more selective for the shell size. In this research, gap between separator grids was
adjusted to economical size of cockle Anadara granosa, which was 40 mm long of shell.
Results showed that dredge with 30o bended teeth caught 919 cockles, or 2.18 times more
than standard teeth of dredge (412 cockles). The using of separator made dredge became
more selective. It only retained cockle Anadara granosa and Anadara antiquata with length
of shell l e” 39.96 mm and l e” 35.11 mm.
