Brasil - Base de datos miRTil reúne información de microRNA que permitirá la manipulación genética de rasgos de importancia económica (crecimiento, resistencia a enfermedades, etc) de la tilapia del Nilo. La tilapia es el tercer pez más cultivado en todo el mundo y una especie modelo para estudio evolutivos. Con el objetivo de mejorar la productividad y contribuir con la selección de rasgos de impacto económico, se han aplicado [...]

Brazil.- Brazilian and German scientists have completed a collaborative project to sequence and analyze the whole genome ofArapaima gigas, a giant freshwater fish known in Brazil as pirarucu and elsewhere asarapaima or paiche. Its growth rate is the fastest among known freshwater fish species. Its natural distribution covers most of the Amazon River basin in Peru and Brazil. The research led to discoveries that help determine sex at an early stage, facilitating the separation of female and [...]

An innovative tilapia farming system that reduces both expenditures on fish feed and mortality rates, among other benefits, has been developed by Fisher Piscicultura and is undergoing final testing in the reservoir behind the Água Vermelha hydroelectric dam. The site is on the Grande River near the border between São Paulo State and Minas Gerais. The innovation consists of the use of round aluminum tanks floating on rafts made up of PET bottles of the type used as containers for soft [...]
