Considerations for tilapia farming in saltwater environments
Tilapias are farmed in a variety of production systems, but mostly in freshwater and low-salinity waters. But tilapias are an excellent candidate for aquaculture in brackish- and seawater because they can tolerate a wide range of water salinity.

La genética es clave para la tasa de crecimiento máxima del camarón
El alcanzar mayores tasas de crecimiento en el camarón cultivado comercialmente tiene muchos beneficios importantes, incluyendo la reducción de varios riesgos, la reducción de costos y el aumento de las oportunidades económicas. La genética del camarón determina principalmente cuanto crecimiento adicional se puede lograr, ya que el camarón típicamente refleja las tasas de crecimiento de sus progenitores.
