devils hole The annual spring count showed 115 pupfish, up from 80 last April April 17, 2016 - 11:42am "The Devil’s Hole pupfish has been under federal protection since 1967, but extinction remains a very real possibility. The population peaked at 544 in 1990 but began to decline in 1996 for reasons experts "still can’t explain". The spring survey in 2013 turned up just 35 pupfish, the lowest total since regular counting began more than 40 years ago."

tapajos Stream ichthyofauna of the Tapajós National Forest, Pará, Brazil Abstract The fish fauna of freshwater streams in the Tapajos National Forest was surveyed and a list of species is presented. The sampling was conducted from 2012 to 2013 during the dry season. Fish were collected with dip nets and seine nets in 22 streams of 1st to 3rd order. Sampling resulted in 3035 specimens belonging to 117 species, 27 families and six orders. The most abundant species were Bryconops aff. melanurus, Hemigrammus belottii, and Hemigrammus analis. Four undescribed species were recognized, one of which is known only from the area of this study. A significant dissimilarity was observed in fish species composition among drainage systems. This is the first survey of the stream ichthyofauna in the Tapajós National Forest, and it presents relevant information for future studies and decision-making in the management and conservation of fish fauna in this conservation unit.
