Culture of Poecilia reticulata (Pisces:Poecilidae)in tropical water bodies, Veracruz, México. Poecilia reticulata,also known as guppy,is the most popular fish in the aquarium environment. Guppys are viviparous fish with high tolerance to extreme temperatures.The development of the offspring takes between 25 and 30 days.We developed a technology for raising guppys,which outlines infrastructure and devices for reproduction,nursery,feeding,and commercialization,evaluating the financial and technical feasibility of this technology in a case study.The complete reproductive cycle occured in floating cages with 1 mm mesh and the method was tested in a tropical lagoon in Mexico.Water quality was monitored throughout the study period (temperature,dissolved oxygen and pH levels).A marketing survey was carried out at all existing aquarium shops in Veracruz City.Data collected depict quantities demanded and offered for each species by season,place of origin,and resistance to handling.The hydrobiological characteristics were:average temperature 31.4 ºC, dissolved oxygen 4.5 mgl-1,and pH level 6.8.With these values we built a production function,and used it to evaluate profitability.We estimate a benefit/cost ratio of 1.16,with a net annual income of US$257.67.The system may provide two permanent jobs.Rev.Biol.Trop.52(4):951-958.Epub 2005 Jun 24.
