An aquaculture pen includes an annular floatation assembly formed from a plurality of float platforms connected end to end. A weight ring is suspended from the floatation assembly by a first plurality of tension members at a central portion of the float platforms. A net support ring is suspended from the floatation assembly by a second plurality of tension members that are attached to the floatation assembly, for example, outboard of the first plurality of tension members. A mesh enclosure for the pen includes a main portion attached to the net support ring, a jump net portion that extends from the net support ring to engage the inboard side of the floatation assembly, and a top portion that closes an upper end of the mesh enclosure.

Fish pen for open sea aquaculture

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.
