Aquatic species
kills can be attributed to
either human activities or
natural causes. Generally,
aquatic species kills in New
Mexico are due to low dissolved
oxygen, botulism, and algal
blooms.
Many aquatic species kills are
from unknown causes. This is
generally due to kills not being
reported to authorities quickly
enough. Causes of kills,
especially in streams and
rivers, are generally short in
duration. While this can still
have large effects killing large
numbers of individuals the cause
may have disappeared by the time
authorities can get to the
scene. For this reason notifying
the authorities must be done as
soon as possible after a kill is
seen or suspected. Whenever a
kill occurs there is the chance
that physical evidence of the
cause of the kill is left
behind. The sooner a kill is
reported the better the chances
of determining a cause.
