Collecting Deep-Sea Fishes and Invertebrates

An Issacs-Kidd Midwater Trawl being brought on board the Research Vessel Robert Gordon Sproul off the coast of California. This trawl was made by a team of ichthyologists and invertebrate zoologists from The Field Museum that were sampling from the midwater (open ocean) at a depth range of 3,500 feet to the surface. The movie is sped up as the trawl is coming in, and then slows down to the real time as the cod end (the end of the net) is opened up to show what was collected. The trawl is full of a diversity of red and brown crustaceans (mysid shrimp, krill, etc.) and silver hatchetfishes and smoothtongues and black lanternfishes and bigscales.
