Physical Characteristics of Rohu Fish
Rohu fish is distinguished by its huge size, silver body, and unique head form.
Rohu is a eurythermal species that does not live at temperatures below 14 degrees Celsius. It is a fast-growing species that can reach 35-45 cm in overall length and 700-800 g in a single year under standard culture conditions. In polyculture, it grows faster than mrigal but slower than catla.
Here is an in-depth examination of its physical characteristics:
- Body Shape: The Rohu features a sleek body with a slightly curved back and a rounded nose.
- Measurement: It may grow to be up to 2 meters long, but most examples are between 50 and 100 cm.
- Weight: Adult Rohu may exceed 45 kg, however, their median weight is between 2 and 5 kg.
- Colouring: The body is normally silver with a golden tint to the scales, and the fins are red.
Dietary Habits of Rohu Fish
Rohu fish, a popular freshwater fish in South Asia, has dietary habits influenced by its natural habitat and physiology.
- Feeding: Rohu fish are omnivorous and prefer a plant-based diet. They are recognized for the following eating habits:
- Herbivorous Trends: Feed mostly on phytoplankton, algae, and vegetation that is submerged.
- Supplemental Diet: Infrequently ingest tiny invertebrates and organic debris.
Lifecycle of Rohu Fish
The lifecycle of rohu fish encompasses several stages, each critical for their development and survival. Here is an overview of their lifecycle:
- Breeding Habits: The spawning process occurs during the monsoon season, which normally lasts from June to September and causes water levels to rise.
- Egg Laying: Females lay hundreds of eggs in water, which are externally fertilized by males.
- Larval Phase: Hatchlings hatch within 18-24 hours and are initially fed from the yolk sac.
- Junior Stage: After a few weeks, they start feeding on plankton and grow quickly.
- Adult Stage: Sexual maturity occurs between 2-3 years, subject to environmental conditions.
Rohu fish might survive up to 10-14 years in the wild, however, this may vary depending on environmental variables and predators.
