Sawfish

A sawfish is an endangered fish that is related to sharks and rays. In America, these fishes argon critically endangered which means it is or so belt up to extinction. right away they live mostly in the waters off the souwest Florida. in that respect ar 7 several(predicate) types of sawfish: genus Pristis genus Pristis (common sawfish), Pristis perotteti (largetooth sawfish), Pristis microdon (freshwater sawfish), Pristis pectinata (smalltooth sawfish), Pristis clavata (dwarf sawfish), Pristis zijsron (green sawfish), and at long last Anoxypristis cuspidata (narrow or knifetooth sawfish). alone of them are on the IUCN (International Union for conservation of Nature) red list. There are 3 main problems: overfishing, home ground loss, and their economic crisis procreative ability. First problem is overfishing. Sawfish are instead faint to catch because it can be caught in almost some(prenominal) types of nets. Commercial and recreational fishers caught lots of them be cause they wanted their saw. At graduation in the Atlantic Ocean near Florida on that percent come along point were tons of smalltooth sawfish, but the fishers caught them too much. One fisher caught 300 sawfish a season. Now in America, they are depleted. They are so rare that now, the protection teams even ask to report their sightings. They are critically endangered, which means chance of extinction.

Second problem is their home ground loss. Shallow water is good for the juveniles to survive. But people force lots of coastal development (dredging, mangrove removal, seawall construction, revision of freshwater flow) and they had fewer places to live. That caused them to die. T hird problem is their low reproductive abil! ity. Like sharks, they breed real slow and produce rattling few babies. Because of overfishing and habitat loss it will take age to reproduce all that amount of sawfish that were killed. I think that sawfish should be forced to create protected.
