Abstract

The fishing implements found in the shell middens, burials and houses of the Samhan and Three Kingdoms period consist of fishing net sinkers, fish harpoons made of bone, spears, fishing needles, iron fish harpoons, and iron fishing needles, all of which are closely associated with the types of sea fish and marine mammals that have been identified in association with those implements. Fishing net sinkers can be classified,according to shape, size and weight, into those that were attached to fixed nets and those attached to thrown nets. The types of fish that could have been caught using such nets include some types of freshwater fish, and marine fish such as sardines, horse mackerel, and mackerel. Fishing needles made of bones and iron were possibly used in pole-and-line fishing and early fishing, but this cannot be known for certain as related accessory instruments have not yet been confirmed. The types of fish targeted include red sea-bream, black porgy, gray mullet, yellowtail, tuna, and spanish mackerel, etc.;the size and shape the needles used would have differed according to the type of fish targeted. Fish harpoons and spears consisted of the fixed type and detachable type and were used to catch marine mammals such as sea lions, whales, and dolphins. They could have only been successfully used when accompanied by highly drilled skill and preliminary knowledge about the targets, and therefore indicte the presence of professionals within the community. In relation to the archaeological sites, the optimum places to catch marine fish and mammals were mostly inland sea locations; sea lions, red sea-bream, spanish mackerel, yellowtails, tuna, spearfish, whales, and dolphins were caught in the coastal waters. The former could be caught in the inland sea due to their circular, returning habits, but the nature of the fishing implements, as well as the presence of boat-shaped ceramic vessels and foreign artifacts, indicates that target fish and mammals were also caught in the coastal waters. Fish that resided on the seafloor, such as rock trout and scorpion fish, would have been caught all year round, and the rest would have been caught mostly from summer to fall. Black porgy and red sea-bream of considerable size could have been caught in the early winter and early spring. Marine mammals would have been caught, by professional groups, mostly to obtain protein, skin and oil, daily necessities, and raw materials for rituals and accessories. The existence of professional groups can be assumed based on the maritime location of the sites, artifacts, the remains of an entire sea lion, and the production of accessories. Moreover, the fact that parts of sea lions were found at inland sites (such as Gyeongsan and Gyeongju), as well as near the sea,suggests the possibility that the sea lions were obtained through exchange – for example, through a bartering system, with professional catching communities.
