The same source said the GNR is to ascertain the cause of fish death in that reservoir which is near the industrial area of ​​Castelo Branco.  “A patrol Protection Agency of Nature and Environment (SEPNA) Castelo Branco went to the site and confirmed the situation [fish kills]. Water samples were collected and some fish, which followed for analysis,” said the captain Miguel Silva . The White Castle GNR also produced an official report that went to the prosecutor. “We have a survey of the dam and tributaries that converge there and it’s all being evaluated,” said Miguel Silva. According to this official, this time “is premature and unwise to proceed with any causes” for the death of fish in that reservoir. Source
