Nypa brackish swamp, Samut Sakhon, Thailand

Sponsored by
The Home Aquarium Brand

Thailand, Central Thailand, Mueang Samut Sakhon District

This biotope is a brackish water swamp near the city of Bangkok in Thailand. There are a lot of Nypa fruticans – a palm species living in brackish water. Some of the fish live in this biotope hiding in the petioles, in the branches and roots of this palm. The others build their bubble nests in it. These unique habitats are shrinking all the time due to commercial development.

Surrounding area

Brackish-water swamps of Tha Chin river estuary have been largely converted to ricefields. The habitat is shrinking all the time due to commercial and agriculture developments near the biotope.

Underwater landscape

The water looks very cloudy and dirty.

Fishes

  • Oryzias javanicus (Adrianichthyidae)
  • Anabas testudineus (Anabantidae)
  • Aplocheilus panchax (Aplocheilidae)
  • Channa striata (Channidae)
  • Boraras urophthalmoides (Adrianichthyidae)
  • Betta mahachaiensis (Osphronemidae)
  • Trichopodus trichopterus (Osphronemidae)
  • Trichopsis vittata (Osphronemidae)
  • Dermogenys siamensis (Zenarchopteridae)

Mollusc

  • Pila ampullacea (Ampullariidae)

Aquatic plant

  • Lemna minor (Araceae) – some areas of the biotope do not have one.

Wetland plant

  • Nypa fruticans (Arecaceae)

Note: The biotope data, more precisely on that of Betta mahachaiensis, is collected by the author’s friend.

Threats to ecology

The estuary is already at risk due to pollution and activities in the estuary and this will be further compromised by floods, droughts, high sea levels and storms. High salinity levels and high temperatures will influence the health of mangrove and Nypoideae forests and affect the distribution of some of their plant species.
