| Summary: | Giant gouramy(Osphronemus gouramy Lacepede, 1801.)
fish value. Organ development of giant gouramy have a role for the success of
the individual live and grow to fingerling. Giant gouramy has a unique structure
on the gills called labyrinth and filamen (modified ventral fins). Information on
the development and structure of both still unknown. The purpose of this study is
to determine the development of the shape and structure of the labyrinth and
filamen giant gouramy. Methods used include observation of morphological and
histological structure using paraffin method, Bouin fixation, staining Hematoxilin
- Eosin and Mallory Acid fuchsin. Labyrinth appeared at the age of 27 after
hatching. At the age of 55 days appears the second slab and continue to grow to
form structures folded. Labyrinth structure in the form of cartilage that has many
blood vessels were enveloped layered epithelium lining. Modification of the
ventral fins appeared first at the age of 29 days after hatching. Filament structure
is a pair of hemitrichia composed by cartilage and collagen, covered by
epithelium, and in the middle are nerves and blood vessels. The such structure of
labyrinth and location in supra branchial chamber it was concluded that labyrinth
as a respiratory organ, while filament structure shows that filament function as a
sensory organ. |
