Introduction
The Lake of Yojoa is located in Honduras, Central America, has a length of 16 km and a width of 6 km, it is located between the departments of Santa Barbara, Cortes and Comayagua.This area has a biodiversity of almost 400 species of birds and 800 species of plants that were identify.
We want to focus on the several native species and the relation it has with introduced speciesof different fishes in this biome. The Yojoa Lake has some trouble with this relation. With this report we are trying to present the several problems the communities of fishes has, caused by thechanges in the biome by introducing new species in their habitat. Native species are rare now and difficult to find them in their own habitat. We are trying to figure out why this is happening.

Studyof a community in a biome: Reasons about why native species have decrease.
In first place we need to know, which are the native species of fishes in this biome?
This species are the Carparena,Chunte, Guapote, Dormilon and the Platera.
Now, this species that are from origin of the lake are being affected. Their number has decrease, their development is difficult, and their growth is beingaffected, every day it gets more difficult to find food and shelter for this species.
What could the cause be?
One clue is that this problem started when new species were introduced in this biome alongwith other communities.
Second clue is that contamination is growing into a big problem today, so this could be a secondary reason.
Which species were introduced in the Lake Yojoa?
This speciesare the Tilapia, the Bass and the Pez Espada (picudo). One important thing to know is that this species are now more common than native species.
Do this new species have had an effect on this biomein context with the native species?
Since these new species were introduced the fighting for survivor turned more violently....
