Ahumoana tawhito (ancient aquaculture): The translocation of toheroa (Paphies ventricosa) and other marine species by Māori
type: CreativeWork
description: Throughout time, humans have cultivated and translocated plants and animals. Ancient mariculture (the cultivation of marine species) often leaves little trace of human agency. Consequently, the extent to which mariculture was used in the distant past largely remains a mystery. In Aotearoa (New Zealand), Māori have a long history of translocating and cultivating terrestrial and freshwater species. Increasingly, it is becoming apparent that the translocation of marine species is a resource management tool that has been utilized by Māori for hundreds of years. Research into the population genetic structure of a large surf clam endemic to Aotearoa, the toheroa (Paphies ventricosa), has led to the hypothesis that Māori have undertaken long-distance transport and translocation of this shellfish during the earlier phases of Māori occupation within Aotearoa. Specifically, this “translocation hypothesis” suggests that Māori successfully transported toheroa from the West Coast of Te ika-a-Māui (the North Island) to the South Coast of Te Waipounamu (the South Island) thereby explaining the unique and disjunct distribution pattern of this taonga (treasured) species. This thesis weaves together knowledge from multiple disciplines to test the toheroa translocation hypothesis, explore technologies used by Māori and reclaim traditional knowledge regarding resource management. An examination of archaeological databases revealed a record that was not consistent with toheroa being endemic to Murihiku (southern South Island). On the west coast of Te Ika-a-Māui, 968 midden records were identified of which 40% either contained or consisted entirely of toheroa. In contrast, along the South Coast of Murihiku (Southland, Te Waipounamu), 122 midden records were examined, of which only 6.5% contained toheroa. Toheroa were not a major component of any of these middens. Toheroa were also absent from a natural shell deposit within Murihiku that pre-dates human arrival to Aotearoa. The general ab…
