Description of Goussia kuehae n. sp. (Apicomplexa: Eimeriidae) infecting the Asian seabass, Lates calcarifer (Bloch)(Perciformes: Latidae), cultured in Malaysian fish farms
Culturing fishes in marine cages is a rapidly
developing area of marine aquaculture. The Asian
seabass Lates calcarifer (Bloch) is a fast growing good
quality fish that is readily cultured in intensive systems
in the South Asian region and in Malaysia in
particular. Although several papers have been published
to date on viral, bacterial, parasitic and fungal
organisms causing diseases in the Asian seabass, the
occurrence of a coccidian infection in this species has
only recently been recorded. We collected sporulated
and unsporulated oo¨cysts of a new species of Goussia
Labbe´, 1986, from the mucus covering the epithelium
of the intestine of L. calcarifer. This paper provides a
description of Goussia kuehae n. sp. Sporulated
oo¨cysts of this species are ellipsoidal, 37–40 lm in
length and 28–30 lm in width. The ellipsoidal sporocysts
are relatively small, 15.2–17 9 5.7–8 lm, and
located loosely in the oo¨cyst. There are residual bodies
both in the oo¨cysts and the sporocysts. Goussia kuehae
n. sp. differs from all known species of Goussia in the large size of the oo¨cysts and in having two types of
oo¨cyst residuum
