Saccostrea cucullata- a local species of oyster
Asiatic hard clam
For the four other clam species below, WWF has designated the minimum size for capture to be 30 mm (or 3 cm). This can be applied to other clam-digging hotspots other than Shui Hau. To manage clam resources, overseas regulatory authorities have implemented fishery plans to control clamming activity.

Commercially important mussels belong to the family Mytilidae and are predominantly marine (see Table 1). Freshwater mussels involved in pearl production belong to the Order Unionida. Commercial Mytilid species come from wild harvest fisheries (global production of 237 823 tonnes in 1999) and a greater proportion from aquaculture (1 451 032 tonnes in 1999).

What is a sponge?
Sponges are animals with dense skeletons that are highly adapted to their environments, although it is easy to see why they may be mistaken for plants. Sponges are found in a wide variety of colors, shapes, and sizes - and scientists believe that the colors of the sponge may act as a protection from the sun's harmful UV rays.
