| Abstract: | Genetic diversity and population structure of snapper (Pagrus auratus, Bloch and Schneider), a coastal demersal sparid fish, were determined using six nuclear microsatellite loci and SSCP (single strand conformational polymorphism) analysis of themitochondrial (mt) DNA D-loop in samples collected across the range of the species in New Zealand. Microsatellite data showed similar results to allozyme data collected in the late 1970s that found differentiation between the north-east and southern populations. In addition, an isolated population of snapper in Tasman Bay was identified. The two data sets provide evidence for the temporal stability of the genetic population structure of snapper over 22 years, with differentiation over relatively small spatial scales separated by oceanographic boundaries rather than isolation by distance. In contrast to nuclear markers, mtDNA did not reveal any significant genetic heterogeneity among samples. |
