![]() Objectives The objectives of this policy are: Molluscan shellfish growers will have predictable, equitable and timely access to molluscan spat. The Gulf Region Molluscan Spat Collection Operational Policy has been designed to complement and be consistent with the National Policy on Access to Wild Aquatic Resources as it applies to Aquaculture. Suspended culture (Water Column) means a method of culture that uses longlines, rafts or other structures which allow the grow-out of bivalves in the water column. Spat Collection Licence means a licence or a written permission that authorises the licence holder to collect bivalve molluscs spat. Mechanical devices that fluidize and sieve the sediment or structures such as “clam tents” or other mesh devices on the sediment surface which encourage settlement by increasing local deposition are used for soft shell clam spat collection. Bottom-based collection is mainly used for soft shell clam. Mussel spat may also be collected by hand or with handheld tools in natural beds. oysters, mussels, scallops) in which artificial substrates (collector or cultch) are placed in the water column for the attachment of spat as the pediveliger larvae settle on hard surfaces to become sessile juvenile molluscs. ![]() Spat collection means the collection of bivalve molluscan spat (e.g. Spat size normally ranges between 5 and 25 mm depending on species and the number of months spat remained on the collector. Spat (Seed) means bivalve molluscan larvae shortly after set until time of removal from the collectors (e.g. Sea ranching means a system of extensive culture of marine animals, in which juveniles are released to forage and grow in their natural environment until they are harvested. Off-bottom Culture means a method of culture that uses tables and supports which elevate the bivalves from the bottom. Molluscan shellfish aquaculture means the techniques used for the culture of edible molluscs (oysters, mussels, soft-shell calms, hard-shell clams, and scallops). Lease species refers to a species authorised to be reared on an aquaculture lease. Lease means an area designated for exclusive use by the leaseholder for aquaculture purposes. Bottom culture means a method of culture in which a protected area of sea bed is used for the grow-out of molluscs (e.g. It includes finfish, molluscs, crustaceans, echinoderms and other invertebrates, as defined in the Fisheries Act, at any stage in its life cycle, as well as marine and freshwater plants. Aquatic organisms means an organism that lives in freshwater or marine habitats. The term “rearing” implies individual or corporate ownership of the organisms being reared and also implies some form of intervention in the rearing process to enhance production, such as regular stocking, feeding, and protection from predators and disease.
