Description
Bighead Carp – Hypophthalmichthys nobilis | Exotic Filter-Feeding Freshwater Fish for Aquaculture
Bighead Carp (Hypophthalmichthys nobilis) is an exotic and large species of freshwater fish found in China and spread throughout Asia, including India. It is amongst the major filter-feeding species utilized in aquaculture because of its rapid growth rate, high feed conversion efficiency, and suitability with other carps cultivated for aquaculture.
Key Characteristics
Scientific Name: Hypophthalmichthys nobilis
Common Name: Bighead Carp
Type: Exotic Carp
Origin: East Asia (China)
Habitat: Freshwater ponds, tanks, reservoirs, and rivers
Feeding Habit: Filter-feeder – feeds on zooplankton, phytoplankton, and suspended organic matter
Aquaculture Significance:
Bighead Carp is easily reared in polyculture systems with Indian Major Carps such as Catla, Rohu, and Mrigal, without competition for food as it feeds on microscopic plankton. It grows rapidly and serves to regulate excessive plankton in eutrophic ponds, thus enhancing water quality and overall productivity.
Growth & Culture Advantages:
Increases to 1.5–2 kg within 10–12 months with good pond condition
Reaches above 25–30 kg in bigger water bodies
Maintains high survival and feed conversion rate
Need not be supplied with artificial food, lowering the cost of input
Market Value & Nutrition:
Bighead Carp offers lean protein with little flavor. It contains a high level of omega-3 fatty acids, vitamins, and basic minerals. It is becoming popular in domestic and export markets because of its nutritional value and biomass production.
