Environment










Reasons of the extinction: 


  • The inbreeding: can't interbreed. They can´t interbreed, becuase people are hunting them before the Bocachico has the lenght or size to interbreed which is 25cm approximately. 
  • Sediment: because of deforestation.
  • Introduction of new exotic species. This exotic species are stronger or bigger than the Bocachico and are eating them.
  • Over fishing: fishing more than the allowed 
  • The use of wrong ways of hunting: use of wrong materials. This materials are, most of them, chemiclas that are polluting the water
  • The contamination of the water. 
  • Stream clugged: people clugg the streams so the fishes are affected. 


Strategies developed to protect the species: 

The strategies developed to protect the specie in which the people, society, entities, and government are involved are the following:

  • making new strategies of conservation, investigation, in which it includes the control, the use and the management of the specie, in this case the Bocachico, for continue having the specie, and make it survive
  • this works and strategies comes from the participation of the different regions  and local communities 
  • the "URRA" for example is helping by the stimuli of the reproduction of this specie, taking into account the increase and decrease of the sinu river specially.
  • not fishing bocachico in a small size



Controversial Question:

Do you think that fishing the bocachico should be illegal?
