LERNAIDAE WILSON, 1917, Anchor worms (family)
Abdomen not clearly separated from the anterior part of the body.

 

LERNAEA, LINNAEUS, 1758 (genus)

145 a. All nauplii stages are not feeding, and planktonic.
Copepodit stages are parasites on fish gills. The
unmetamorphosed adults are planktonic. Metamorphosed
adults parasitic, e.g. in the skin tissue, in head embedded in eye, nostril, musculature, with body protruding externally. Hosts: Anabas testudineus, Carassius auratus, Channa striata, Chanos chanos FORSKÅL, Glossogobius biocellatus, G. giuris, Terapon plumbeus, Tilapia and Cyprinus carpio (Common carp). Believed to have been introduced along with importation of an unknown host (see Velasquez 1979). Has caused great economic loss to freshwater milkfish in Laguna de Bay fish cultures. (Figures 145a1, 145a2, 145a3)
- Laguna de Bay, Luzon (copepodite).

    (Syn: Lernaea sp.)
             [1974, 1980, 1984a (sp.), 1997]

145 b. Location: head embedded in musculature with body protruding externally. Hosts: Anabas testudineus, Glossogobius giuris. The report of this copepod from Anabas testudineus involved an experimental infection.

LAMPROGLENA NORDMANN, 1832 (genus).
Larval development similar to Lernaea

 

146 a. Location: gills. Host: Oreochromis niloticus niloticus.  This parasite appears to have entered the Philippines with the recent importation of Nile tilapia from Africa for broodstock improvement.
- Luzon.
