The investigation of the relationship between parasite fauna of offshore cetaceans and ecological factors in Taiwan / 臺灣近海鯨類之內寄生蟲相與生態關係之研究

碩士 / 國立臺灣大學 / 獸醫學系 / 84 / The Survey about the endoparasites of Cetaceans in Taiwan is
usually poor. The aim of this study is designed to survey the
parasite fauna of cetaceans appearing around Taiwan oceans and
the relationship between the parasite fauna and the ecologic
factors. Totally 394 cetacean bodies (at least 16 species)
collected by Dr. Chou, Department of Zoology NTU, throughout
the island since 1994. Jan. to 1996. Apr.. One hundred and
thirty of them were examined for the parasites, 38.46% of them
were parasite-infestated. The locations of parasites were
mainly in the GI tract, pancreatic duct, cranial sinus, muscle
tissue and blubber tissue. According to taxonomic
identification, they are identified in 4 groups: trematoda,
cestoda, nematoda, and acanthocephala. They are respectively
nematoda: Ascaroidea, Anisakis sps.(A.simplex, A.physeter),
Porrocaecum sp., Stenurus sp., Crassicauda sp.(doubted);
Acanthocephala: Bolbosoma sp.(2 species), Diplospinifer sp.,
Rhadinorhynchinae(2 species); trematoda: Zalophotrema sp.,
Lecithodesmus sp., Orthosplanchus sp. and cestoda:
Trigonocotyle sp.(2 species). We take infestation, fauna
richness and infestation intensity as dependent variables, and
analyse the relationship with the ecological factors. We found
that the more effective ecological factors on parasite fauna
are: cetacean species, sampling localities and distribution
types. The less effective factors are: cetacean sex and
sampling time.
