areas that had been in direct contact with
the polyethylene bag.
In general, females longer than or equal
to 375 cm and males of body length longer
than 494 cm were referred to as matures
(Bloch et al., 1993; Martin and Rothery,
1993; Desportes et al., 1993).
White-sided dolphins
Samples of white-sided dolphins were col-
lected during a drive in Klaksvík on 21 Au-
gust 1997. The hunt of dolphin is very lim-
ited in comparison to that of the pilot
whale, but occasionally such schools are
taken and the kill is done in the same man-
ner as the pilot whale kill. The sampling,
sample storage, and sub-sample prepara-
tion were done in the same manner as for
the pilot whales. Dolphins become sexual-
ly mature at an age where they have at-
tained a whole body length of 190 to 220
cm for the females (which equates to 12
years) and 210 to 240 cm for the males
(Bloch and Fuglø, 1999). Individuals that
where equal to or longer than the average
length at maturity, which is 205 cm and 225
cm for females and males, respectively,
were considered to be adults.

The results are shown with mean and standard deviation (bold) and minimum and maximum values for the
groups ofadult and juvenile, females and males.
