Number of discard species from commercial scale was higher than small scale (Table 4).
Though some those species have marketable value but they still were discarded since small size, or too
few catch or damaged from the operation.
The size of blue swimming crab from each fishing type is shown the comparison in Figure 2. It
shows clearly that small scale fishermen (inshore fishing ground) catch the big amount of the small size
crab while commercial scale (offshore fishing ground) catch the larger size from their operations due to
the different of fishing ground.
