Fish Stringer
A fish stringer is a line of rope or chain along which a fisherman can string fish so they can be immersed and kept alive in water.Toth, Mike (2000''The Complete Idiot's Guide to Fishing Basics''Second edition, pp. 158–159, Penguin. . A rope stringer ''(pictured)'' is the simplest type of fish stringer. It consists of a line of rope or wire with a stringing needle made of metal or hardwood at one end. The other end usually has a removable wire ring which can be used to secure the stringer. June 1923, 39 (6): 964. Using the needle, the stringer is threaded through the fish gill

Fish Gill
Fish gills are organs that allow fish to breathe underwater. Most fish exchange gases like oxygen and carbon dioxide using gills that are protected under gill covers (operculum) on both sides of the pharynx (throat). Gills are tissues that are like short threads, protein structures called filaments. These filaments have many functions including the transfer of ions and water, as well as the exchange of oxygen, carbon dioxide, acids and ammonia. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. Within the gill filaments, capillary blood flows in the opposite direction to the water, causing counter-current exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx. Some fish, like sharks and lampreys, possess multiple gill openings. However, bony fish have a single gi ...
