An aquaculture feasibility study for Ngai Tuahuriri: Presented in partial fulfilment of the requirements for the Degree of Master of Science in Resource Management

Abstract

This report assesses the feasibility of a sustainable aquaculture development for the Ngai Tuahuriri of Tuahiwi. The report focuses on a site situated 2-4 kilometres north of the Ashley River/Saltwater Creek Estuary mouth, in Pegasus Bay, Canterbury. Background to the social, physical, ecological and legal characteristics of any proposed development are detailed along with an account of aquaculture in New Zealand. Species thought to have an aquaculture potential are evaluated within a framework incorporating available information and a risk assessment procedure. Evaluation of the species with potential for aquaculture indicates that none are suitable for the Ashworth Ponds site. The report also provides information and contact sources relevant to aquaculture options at other sites in Canterbury. Finally sustainable harvesting of tuatua/surf clams from the subtidal and intertidal zones is comprehensively dealt with in a management strategy. This provides an alternative to aquaculture for Ngai Tuahuriri at the Ashworth Ponds site.
