With the relocation of various species of fish in the Orotoy is seeking to regain the river has been affected by human interventions. After the accident in April 2009, when he accidentally fell into the waters of the river Orotoy of Castilla La Nueva, a chemical used by Ecopetrol, the state firm decided to find a way to give back something to the river to give it life. This agreed with the fishing cooperative Coopesca develop a proposal made by the community to recover the lost fish. Parada Sandra Guevara, a biologist who led the project, explained that this was done through the relocation of fish from the same basin.

... and adult animals were brought from the same species to relocate, but not before taking a census and their behavior.



"We needed to understand the dynamics of the river and the animals and see if they agreed with the relocation. Then we constructed 12 cages that resembled their habitat with environmentally friendly materials, meshes, fibers, and we put some weights so you do not drag the channel and power located at various sites of the river, "he said.


A nicuros, catfish, barbel, Mouth, sunfish, spoons, striped and more of the 30 species identified, it became a biometrics to calculate their sizes and weights and to distinguish them.


Then the animals were installed in the cage and after a time they were locked up, broke the screen to come out and there were animals in cages.


"The relocation process works, but you have to make a judicious monitoring process for the fish to recover. It's so good to find positions of eggs, which means that the site was accepted to reproduce," said the biologist.
