SCENARIO example:

1. Go to Ensembl Zv9 (http://mar2015.archive.ensembl.org/Danio_rerio/Info/Index).
2. Search for gene "ghra".
3. Go to the "Location" tab.
4. Click on "Configure this page" on the menu on the left.
5. Click on "RNASeq models", under "Genes and transcripts".
6. Select all the rows on the "Exons" column.
7. Save and close (check mark on the upper left).

Now we can see the developmental stages at which the transcripts related to that gene are expressed, according to RNA-seq data.

QUESTION:

Is it possible to download the list of all transcripts and genes that are expressed at a specific developmental stage in zebrafish? If yes, how? I'm new in bioinformatics. I have tried BioMart, but it doesn't have the option for RNASeq per developmental stage.
