碩士 / 國立臺灣大學 / 微生物學研究所 / 86 / ABSTRACT From Octorber 1997 to March 1998, 410 saltwa
ter fishes belonging to 67 Species and 49 cephalopods belonging to 7 species w
ere examined for the infection of anisakine larve. A total of 2,044 larvae, in
cluding 1,899 anisakine larvae and 145 unidentified larvae, were obtained from
32 species of saltwater fishes. The collected anisakine larvae were classifi
ed for the larvae types according to the methods of Koyama et al.(1969,1974).
The results obtained were as follows: Anisakis Type I: 1,161 larval (56.8%) co
llected from 17 species of fishes; Terranova Type B: 2 larvae (0.1%) collected
from one species offishes; Raphidascaris : 245 larvae (14.5%) collected from
13 species of fishes; Thynnascaris Type A: 476 (28.3%) collected from 14 speci
es of fishes; T. Type B:3 larvae (0.2%) collected from 3 species of fishes;T.
Type C: 12 larvae (0.7) collected from 3 species of fishes; and unidentified l
arvae: 145 larvae (8.5%) collected from 15 species of fishes. The following 1
4 species of fishes were infected with higher infection rates of anisakine lar
vae: namely, Scomber japonicus (19/19),S. australascius (4/4), Decapterus maru
adsi (31/33), Trichiurus lepturus (15/21) Trachurus japonicus (10/11), Carango
ides equula (7/7), D. kuroides (16/24), Johnius sina(10/11), J. tingi (1/1), N
emipterus japonicus (10/10), Saurida filamentosa (2/2), Aulopus japonicus (8/8
), Mene maculata (9/11), and Sphyraena japonica (1/2). Anisakis Type I larvae
were tested for the survival at low temperatures. The results obtained were:
the larvae were completely killed when frozen at -16C for 26 hours, but all t
he larvae were survied when they were kept at 5C for 24--72 hours. Another ex
periments were tested for the survival ofAnisakis Type I larvae in 4 different
concentrations of eitherwasabi and soysauce or ginger juice and vineger for 1
0 min to 3 hr.The results revealed that no larvae were killed in the latter co
mbinations.But in the former, several larvae died after 1-hr treatments and al
l the larvaedied after 2-hr treatments except only a few survied in therepeate
d 2-hr treatments. Based on the results obtained, the freezer of thefamily re
frigerator is absolutely capable to kill anisakine larvae afterfrozen for 26 h
r. But both the combinations of wasabi and soysauce orginger juice and vineger
are not valid to kill the larvae in the shorttime treatment before consuming.
