A mortality trap () for a spar buoy fish pen () is configured to receive and trap deceased fish, or morts (M), that sink from the fish pen. The mortality trap attaches to a lower portion of the spar buoy () to define a first passage (). The sinking mort passes into an upper receiver portion (U) of the mortality trap, and encounters a sloping transverse panel (). Gravity causes the mort to continue through a second passage (B) into a lower entrapment portion (L), and further into a region underlying the transverse panel () preventing the mort from escaping if it becomes positively buoyant. The entrapment portion optionally includes a converging channel into a valved port, to permit extraction of morts. The mortality trap may be located on the distal end of the spar buoy, or at an intermediate location on the lower portion of the spar buoy.

Aquaculture fish pen with mortality trap

A fish pen () includes an elongate spar buoy () and an optional reserve buoyancy buoy () disposed over a top end of the spar buoy. One or more rim assemblies () are attached to the spar buoy with tension members (). An adjustable upper connection plate () on the spar buoy provides a means for tensioning the tension members. A docking station () and portal () provide easy access to the fish pen. A deployable panel system () allows for crowding fish into a smaller portion of the pen. The panel system may be nonporous and include additional panels () such that a portion of the pen can be substantially isolated.
