Sawfish

A sawfish is an endangered fish that is related to sharks and rays. In America, these fishes atomic number 18 critically endangered which means it is or so shut out to extinction. right away they live mostly in the amniotic fluid off the souwest Florida. on that school principal are 7 contrary 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). all(prenominal) 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 downcast procreative ability. First problem is overfishing. Sawfish are instead at large(p) to catch because it can be caught in almost either types of nets. Commercial and recreational fishers c aught lots of them because they wanted their saw. At premier in the Atlantic Ocean near Florida on that 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 habitat loss. Shallow water is good for the juveniles to survive. But people effect lots of coastal development (dredging, mangrove removal, seawall construction, revision of freshwater flow) and they had fewer places to live. Th! at caused them to die. Third problem is their low generative ability. Like sharks, they breed real slow and produce really few babies. Because of overfishing and habitat loss it will take be on to reproduce all that amount of sawfish that were killed. I think that sawfish should be forced to create protected.
