Figure 3 Eco-geographical variable spatial distribution maps: a. seabed sediments (φ); b. depth (m); c. distance from estuary (km); d.
sea surface TSS (mg/L); e. seabed current velocity (m/sec); f. seabed temperature (°C); g. seabed salinity (‰); h. seabed pH; and i.
seabed plankton density (ind/L) in Brebes District with scallop distribution locations. Kabupaten Brebes=Brebes District, Laut

Tolerance resulted by ENFA
determined by the high plankton density (m = 0.657)
and deeper water depths (m = 0.596) (Table 3).
TSS variables and seabed sediments with relatively
equal weight determined the habitat of scallop on the
next order. Scallop preferred waters with a lower
