Evaluating production performance and behavior of juvenile pikeperch with other fish species in RAS monoculture and polyculture.
Study evaluates Nile tilapia in monoculture and polyculture with giant freshwater prawns in biofloc and recirculating aquaculture (RAS) conditions.
Egypt is the third-largest tilapia producer globally, after China and Indonesia, and accounts for about 80 percent of African production of farmed tilapia. Many of the reasons for Egypt’s successful development of its important tilapia industry could be applied to
The U.S. Soybean Export Council’s farm demonstrations, farmer education efforts and formulated feeds are boosting tilapia production in rural areas of Myanmar, where indigenous carp are more commonly raised.
Seasonal pathologies reduce the profitability and sustainability of the shrimp-farming industry in New Caledonia. A study was therefore conducted to estimate the effects of polyculture of blue shrimp with goldline rabbitfish or mullet on production performance and environmental quality.
Field trails in Alabama, USA, demonstrated the potential of raising striped mullet with Pacific white shrimp in inland ponds. Using wild-caught fingerlings at low density, the trials found the same survival rates as for mullet and shrimp grown separately.
In a study of pond polyculture, manipulation of species composition improved fish yield and corresponding income. Selling the whole production increased income 27 percent.
Tilapia culture in Ecuador is marked by vertically integrated companies that manufacture their own feeds and practice polyculture with Pacific white shrimp.
Even in commercial systems, management of self-recruiting species within diverse polycultures can reduce risk and produce valuable byproducts.
