P. ornatus lobsters are caught throughout the year, although in some jurisdictions there are seasonal fishery closures applied as part of the resource management. Fisheries for the puerulus stage operate in Vietnam, Indonesia and the Philippines. These are seasonal, the settlement occurring 4-6 months after spawning from the source reproductive stock. In Vietnam the puerulus season extends from September to March.
A net shot by hand or from a small boat in a circular shape then drawn ashore by hand from both ends. To target fish living close to the shoreline. Usually worked clear of the seabed or with very light contact therefore very little seabed impact. This method of fishing is used in shallow, inshore waters that can be nursery grounds therefore there is the possibility of the capture of immature fish.
Fishermen harvest seafood by hand because the animals in question are slow-moving. Diving equipment and nooses are used to help collect the animals when they live more than an arm’s length from the surface of the water. These methods produce live lobsters that fetch the highest price. There is some fishing of P. ornatus by spear, which produces dead lobsters that must be frozen shortly after capture. Frozen lobsters are lower value.
Fisheries for the swimming post-larval ‘puerulus’ stage of P. ornatus lobsters have developed in Vietnam, Indonesia and the Philippines. Traps simulating natural settlement habitat (bundles of net or folded material to create crevices) are suspended from floating frames. The swimming pueruli settle in the traps and are removed. These seed lobsters are then traded for aquaculture purposes.
