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.

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.
Lernaea lophiara HARDING, 1950
Lernaea sp. from Laguna de Bay
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.
