Transparent goby, Aphia minuta





The local name for the fishing gear used in this fishery is “jonquiller” or “xarxa jonquillera”. In effect, it is a seine, a fishing technique that involves catching the fish by surrounding them with a wall of netting. The seine is made up of a cone-shaped body, two long wings and a bag. The most important elements for seine capture efficiency are the long lines extending from the wings, used to surround a large area.

This fishery is located on the Balearic Islands, to the east of the Spanish coast.
