Aquaponics - Integration of Hydroponics with Aquaculture

Because I was working in a government institution (SENA-National Service Learning)) as an instructor at the livestock, I think it is important the topic, but I attacked several concerns including:

If I have vegetation above water, the sun can not penetrate into it, so there will not be enough plankton to feed fish filter as Mojarra.

- By adding minerals to feed the plants, affect the pH of the water and it’s variations are limiting aspects of the production of fish.

- When the sun does not penetrate properly into the water, temperature is not recommended to increase fish production levels.

These among others are some of the doubts.

Finally, I wonder whether it is justified to do this?. Not wanting to be that a combination of vegetables and fish are diminishing the productivity of the pond?

If you can answer these concerns in Spanish. It would be easier for me. Otherwise you can do it in English.
