This ‘Lot’ has been found frequenting marshy weedy thickets along Suswa river in the Eastern Doon and Asan in Western Doon.

Characterization:

• The fishes of this ‘Lot’ have two things in common i.e.,

(a) The presence of a long-based dorsal fin and the presence of spines (spiny rays) in the dorsal, anal and pelvic fins, a characterization of the Order: Perciformes (most diversified of all the orders).

(b) The presence of Ctenoid scales on the body, extending up to behind eye orbit.

Segregation:

• This lot can be segregated into ‘2 Sub-lots’, on the basis of diagnostic colourations:
  • Sub-lot 1: Brightly coloured (bluish, reddish, golden hues) with dorso-ventrally obliquely running bands on the flanks.
  • Sub-lot 2: Drab coloured with dark brown ground colour and more darker vertical bands on the flanks and a black spot covering one full scale just above the base of preopercle.
• Sub-lot 1 has two more characters different from the Sub-lot 2 i.e., presence of a long filamentous ray in place of the pelvic fin and a long-based anal fin, too (in addition the long-based dorsal fin).
• Identify this Lot ….as species belonging to Genus Colisa / Trichogaster

• Sub-lot 2 is different from the Sub-lot 1 in having only a long-based dorsal fin, anal fin being shorter.

Identify this Lot ….as species belonging to Genus Badis as Badis badis

LOT – 8 [SUB-LOT 1]

[Order: Perciformes; Suborder: Anabantoidei; Family: Osphronemidae; Subfamily: Luciocephalinae (Nelson, 2006)]

The sample identified as belonging to Genus Colisa (= Trichogaster) can be segregated into 3 species viz.,
Colisa lalia (= Trichogaster lalius)
Colisa fasciatus (= Trichogaster fasciata)
Colisa labiosus (= Trichogaster labiosa)
