Abstract: An apparatus for incubating a plurality of receptacles includes one or more thermally-conductive receptacle holders, each comprising a plurality of receptacle wells. A thermally-conductive support is associated with each of the receptacle holders, and a thermal element is positioned between the associated support and the receptacle holder. A heat sink is in thermal communication with the support and comprises a plurality of spaced-apart fins. An optical fiber associated with each receptacle well has a first end positioned adjacent to or within a through-hole formed in the receptacle well and extends through through-holes formed in the support and the heat sink aligned with the through-hole of the receptacle well. Each of the optical fibers is positioned between two adjacent fins of the plurality of fins.

Abstract: A device for retrieving snagged lures has a rigid loop of stiff rod or wire mounted on a pole. The loop is made up of several portions placed in the same plane with one another and connected to a support portion mounted in the pole. The loop has first and second portions that define an acute angle between them at a corner for reaching over and grasping a lure for pulling it upward. A crossover portion completing the loop extends over the first portion and provides a tip for engaging a line and guiding it through a gap and into the loop. Also disclosed is a weighted device which is not connected to a pole, but which includes a similar loop.
