Commercial production of Trichogaster trichopterus

The regional aquaculture centers integrate individual and institutional expertise and resources in support of commercial aquaculture development.

The Center produces a number of publications, including this ‘Manual for Commerical Production of the Gourami, Trichogaster trichopterus, a Temporary Paired Tank Spawner‘.

Gouramis are commonly known as labyrinth fishes. These fish are characterized primarily by an accessory breathing organ called the labyrinth organ. The labyrinth organ is located next to the gill cavities and is made up of folded membranes mounted on a bony frame. The delicate tissue has a high concentration of blood vessels and functions much like a terrestrial lung. If a labyrinth fish is denied access to the air it will drown because the gills alone will not provide sufficient oxygen to the fish.

This ‘lung’ adaptation is essential in the oxygen depleted waters that are home to gouramis. The image below shows typical Trichogaster habitat.
