Abstract or Summary
  • The experiences on reproductive management of native specie such as Petenia splendida (Tenhuayaca) in the last four years in Tabasco, Mexico has generated enough information to allow the development of a technological package for supporting sustainable rural production, particularly in areas where most of the population belongs to ethnical groups. The chontales is the most representative ethnic group in Tabasco. Nowadays, despite agriculture and fishing are still the main "natural" economic characteristic of the chontales, amid of a poorly developed livestock rearing carried out by a few with a little more capital, the economic revenues of the chontales can be among the lowest in the country. Although their precarious economics, this tribal group is interested in the rescue, conservation and sustainable production of the native fish by aquaculture means. The native species have an important place in local consumption trends and traditions. Native species have an established local market and high demand, as consequence of over-fishing and introduction of exotic species. Market price of the native species is generally superior (over 30%) to the one of introduced species, particularly in the case of Tenhuayaca (P. splendida), which has a highly competitive price and similar to Centropomus undecimalis (Common snook). The establishment of a hatchery system for Tenguayaca has allowed this tribal group to pursuit new markets at the local and regional level to improve their livelihoods and restocking of local fishery.
