A method of growing shellfish is disclosed. The method comprises obtaining a support tray (I) with recesses (7) where at least some of the recesses (7) incorporate means adapted to create a deliberately formed alphanumeric, written or pictorial mark on the shellfish as it grows. Shellfish spat are attached to at least some of the recesses (7) and the tray (I) is placed in water so that the spat grow into substantially mature shellfish within the recesses (7). The spat each grow generally in the shape of their respective recess (7) so that the mark is created on the shellfish as it grows.

A precast dam structure includes at least two precast segments coupled together via linkages and a flow path structure. The flow path structure defines a flow path having an intake port and a draft port and is associated with at least one of the at least two precast segments. The flow path structure is configured to provide a change in flow direction, either internally or externally, from the at least one of the at least two precast segments.

A system for preserving or establishing an ecosystem comprises an assembly coupled to a guidance component. An assembly comprises an enclosure and a substrate, and is configured to contain one or more organisms within the enclosure. The guidance component causes the assembly to be transported to a destination environment. The assembly is decoupled from the guidance component. The assembly detaches from the substrate, to integrate the one or more organisms into an ecosystem of the destination environment.

A new acoustic tag and process are disclosed for identifying and tracking underwater hosts in up to three dimensions. The acoustic tag has an operation lifetime up to a year or longer at a pulse rate interval of about 15 seconds. The acoustic tag has a signal detection range up to at least about 500 meters that enhances detection probability.
