Abstract: Abstract: In this study, we analyzed the morphometric variation between
Photololigo edulis and P. chinensis occurring in the
waters around Taiwan by using univariate and multivariate
morphometric methods. We measured 18 morphometric characters
from 749 squid specimens, which were collected from
the waters in three regions: off northeastern Taiwan, Penghu,
and Hsinchu, respectively. Based on these data, the result
from the univariate morphometric method showed that the
morphometric characters of P. chinensis from Hsinchu were
more different from those of P. chinensis from Penghu as well
as those of P. edulis from northeastern Taiwan. However,
through the stepwise discriminant analysis, a multivariate
morphometric method, 13 morphometric characters were
selected and discriminated the specimens among the three
regions with a correct classification rate of discriminant functions
of 84.65%. Also, the morphometric characters of specimens
from the waters off Penghu and Hsinchu were more
similar than those specimens from the waters off northeastern
Taiwan.
