Future Trends of Tilapia Aquaculture in the Americas

Nicaragua

Lake Nicaragua supports a significant tilapia fish- ery that supplies local and export markets. A number of small farms also supply local markets. Large scale farms are likely to be built in the southwest part of the country near the Costa Rican border.

Nicaragua is likely to become an important pro- ducer of tilapia from intensive pond farms and from cages placed in lakes and reservoirs. Low labor costs and abundant water supplies provide excellent op- portunities for growth.

Panama

Panama has had small farms for many years. Two large scale intensive pond farms are in plan- ning stages. Panama is likely to become a signifi- cant exporter because it has excellent transportation and other infrastructure facilities.

Paraguay

Tilapia were introduced in the 1960s and popu- lations were established in the watershed of the Rio Plata. A fish farming cooperative has been organized to produce tilapia for domestic markets. The coop- erative supplies 5 t/mo and has processing capabili- ties (Frank Fragano, pers. comm.). Additional production capacity is being developed and they hope to market frozen fillets to US markets.

A slight increase in domestic consumption will occur and exports to US and Brazil will develop.

Peru

Peru is unique in the Americas regarding tila- pia. Tilapia production has decreased since the early 1990s. Many regions of the country are ideal for ti- lapia production, which peaked in 1992 with 250 t. By 1996 production had decreased to 47 t and today there is little commercial cultivation.The agriculture ministry of Peru has decided to concentrate on the aquaculture potential of native species. Aquaculture of tilapia, an exotic, has been discouraged. Tilapia production is not allowed in the Amazon Basin and no permits are issued for production in reservoirs throughout the rest of the country. Pond culture is allowed only for all male populations. Production in the early 1990s was in ponds and cages. Experi- mental production was conducted in integrated sys- tems with ducks, cattle, and pigs as well as in rice culture. O. niloticus and red strains were reared. In 1999, the government announced that the demon- stration farm facilities would be auctioned to the private sector. A separate research program was con- ducted in Lima. Tilapia production in treated mu- nicipal effluents was evaluated with the intent to determine if any potential human pathogens, that might be transmitted by fish to humans, were present in water after secondary treatment.

Aquaculture of endemic species will develop and tilapia production will be restricted to the coastal plain. Some production may develop in the shrimp growing region.

Suriname

Suriname has extensive water resources and great potential for tilapia production. O. mossambicus were first introduced for aquaculture in 1955 by the Fisheries Department. Commercial aquaculture did not develop at that time, but tilapia were stocked into natural water bodies. A small com- mercial fishery has developed harvesting these fish (Ouboter and Moll 1993). There are 2 small farms in operation and a large farm in the start-up stage. COMFISH is a 4 ha farm on the Commewijne River in close proximity to the capitol of Paramaribo. COMFISH uses the ND30 strain, developed by APT in Israel, in an intensive operation with anticipated production of 100 t/y (T. Frese, pers. comm. http:// www.fishfarming.com/). The farm sex reverses fry before stocking into earthen nursery ponds. Growout is in 0.1 ha concrete tanks, stocked at 17 juveniles/
