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 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 Organ (anatomy), organs that allow fish to Aquatic respiration, breathe underwater. Most fish Respiration (physiology), exchange gases like oxygen and carbon dioxide using gills on both sides of the pharynx (throat). Gills possess Tissue (biology), tissues resembling short threads, referred to as gill filaments or Lamella (surface anatomy), lamellae. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Other than respiration, these filaments have other functions including the exchange of ions, water, acids, and ammonia. Fish respire 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 countercurrent 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, but the mo ...
