Udang galah temburong is distinct from other udang galah species due to its:

  • Larger size:Can grow up to 30 cm in length, making it one of the largest udang galah species.
  • Distinct coloration:Has a dark brown or black exoskeleton with yellow or orange markings.
  • Geographic isolation:Found only in the Temburong River basin, making it a unique and endangered species.

Habitat and Distribution

Udang galah temburong inhabits freshwater streams and rivers with clear, fast-flowing water. It is primarily found in the middle and upper reaches of the Temburong River and its tributaries. The species is also found in several other rivers in Brunei, but the Temburong River population is considered the most significant.

Habitat and Environmental Requirements

Udang galah temburong, also known as the Temburong river prawn, is a freshwater prawn species native to the Temburong River in Brunei. Its survival and well-being depend on specific habitat requirements and environmental conditions.

These prawns prefer clear, flowing water with high oxygen levels. The optimal water temperature range for their growth and reproduction is between 25 to 30 degrees Celsius (77 to 86 degrees Fahrenheit).

Substrate Preferences

Udang galah temburong typically inhabit areas with sandy or muddy substrates. They prefer substrates that allow them to burrow and hide from predators.

Biology and Life Cycle

Udang galah temburong, also known as the Temburong river prawn, is a crustacean species native to the Temburong River in Brunei. It is a freshwater prawn belonging to the family Palaemonidae and is known for its large size and distinctive coloration.

The biology and life cycle of udang galah temburong are complex and involve several distinct stages of development. Understanding these stages is crucial for effective conservation and management of this species.

Larval Stages

Udang galah temburong begins its life as a planktonic larva, drifting in the water column. The larvae go through several molts, gradually developing into juvenile prawns.

Juvenile Stages

As the juvenile prawns grow, they settle to the bottom of the river and begin to feed on algae, detritus, and small invertebrates. They continue to molt and increase in size, developing the characteristic coloration and morphology of adult udang galah temburong.

Adult Stage, Udang galah temburong

Adult udang galah temburong are typically large, with males reaching up to 30 cm in length and females slightly smaller. They are characterized by their long, slender bodies, reddish-brown coloration, and prominent claws.

Reproductive Behavior and Spawning Habits

Udang galah temburong are sexually mature at around 1 year of age. Mating occurs during the rainy season, when water levels are high. Females carry the fertilized eggs on their pleopods (abdominal appendages) until they hatch into larvae.

Nutritional Value and Culinary Significance

Udang galah temburong
