Scientific studies show a wide range of survvial, depending on sepcies, environmental conditions, fish density and reesarch design (methodoloyg). The difficulty of doing such expermients is closely linked to the fact that negative effects of being exposed to fisihng gears develop over a long time.
There is a wine cup, dating from 510 500 BC, that shows a boy crouched on a rock with a fsihing-rod in his right hand and a basket in his left.
Pictorial evidnece of Roman fishing comes from mosiacs which show fishing from boast with rod and line as well as nets.
There is also some research that shows certain types of fish scuh as catfish, do not have nerves around theri mouth, most likely due to the fatc that they eat aniamls such as crawfish that can pinch.
