| Miêu tả: | Poecilia reticulata, also known as guppy, is the most popular fish in the aquarium environment. Guppys areviviparous fish with high tolerance to extreme temperatures. The development of the offspring takes between25 and 30 days. We developed a technology for raising guppys, which outlines infrastructure and devices forreproduction, nursery, feeding, and commercialization, evaluating the financial and technical feasibility of thistechnology in a case study. The complete reproductive cycle occured in floating cages with 1 mm mesh and themethod 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 aquariumshops in Veracruz City. Data collected depict quantities demanded and offered for each species by season, placeof origin, and resistance to handling. The hydrobiological characteristics were: average temperature 31.4oC,dissolved oxygen 4.5 mgl-1, and pH level 6.8. With these values we built a production function, and used it toevaluate profitability. We estimate a benefit/cost ratio of 1.16, with a net annual income of US$257.67. Thesystem may provide two permanent jobs. |
