Endemic species

December 16, 2016 by abby

A fish species is considered endemic to a location if that is the only place it occurs naturally.  It may have evolved in that region or over time has become so adapted to that specific environment that it cannot survive elsewhere.  For example, Devil’s Hole Pupfish (Cyprinodon diabolis) is only found in Devil’s Hole, Nevada.  If a … [Read more…]

A fish species is considered native to a location if it occurs naturally there.  It may have evolved in that region or dispersed and become established there without human assistance.  For example, Lake Trout (Salvelinus namaycush) is native to some locations in North America but is considered non-native in other locations where it has been introduced … [Read more…]

Turtle Excluder Devices (TEDs) are a specific type of bycatch reduction device (BRD) that are a modification to a trawl net to keep turtles, which are not targets of the fishery, from being caught in the net.  TEDs are generally composed of a set of bars over the trawl net.  While small target animals, such … [Read more…]
