翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Diseases and parasites in cod ： ウィキペディア英語版 Diseases and parasites in cod Cod and related species in the family Gadidae are susceptible to a variety of diseases and parasites. ==''Laenaeocera branchialis''== ''Lernaeocera branchialis'', the "cod worm", is a copepod that infects gadoids. The first host used by cod worm is a flatfish or lumpsucker, which it captures with grasping hooks at the front of its body. It penetrates the lumpsucker with a thin filament which it uses to suck the host's blood. The nourished cod worm then mates with another one on the lumpsucker.〔Matthews B (1998) (''An Introduction to Parasitology'' ) Page 73–74. Cambridge University Press. ISBN 978-0-521-57691-8.〕 The female worm, with her now fertilized eggs, then finds a cod, or a cod-like fish, such as a haddock or whiting. There, the worm clings to the gills while it metamorphoses into a plump, sinusoidal, wormlike body, with a coiled mass of egg strings at the rear. The front part of the worm's body penetrates the body of the cod until it enters the rear bulb of the host's heart. There, firmly rooted in the cod's circulatory system, the front part of the parasite develops like the branches of a tree, reaching into the main artery. In this way, the worm extracts nutrients from the cod's blood, remaining safely tucked beneath the cod's gill cover until it releases a new generation of offspring into the water.〔〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Diseases and parasites in cod」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
