Some things you should to know:

Import data from fishbase.

Nyagua is able to import some fish data from Fishbase xml files. Simply go to Fishbase with Your browser and select the fish You want to get data for.

At the bottom of fish data there is a "Get xml file" link. It will show xml data in your browser.

Save those data in a file, goto Nyagua FishBase tab and chose the [Import FishBase XML] button .

Select the file you downloaded and You will get data loaded in the fields. Some adjustments are needed depending on how the data are written in fishbase.org for single item (eg. temperature is not yet retrived in correct field).


Since version 5.0.0 was introduced a new feature that prevents the download and manual upload of files and allows you to search and import the data directly from www.fishbase.org.

The icon that launches the functionality is shown below. The mode of use is intuitive but will still be explained in Fishbase section of the manual.


Since Nyagua v. 2.0 an internal engine has been developed to plot so gnuplot is no more required. This engine provides only basic functions so if You need zooming and other advanced features you need gnuplot to be installed.

When you click on Plot button a window is shown to ask what to plot, how to plot and where to plot (video, file or printer). You can change default settings of this window in Options / settings menu . All settings starting with "pl_" are related to plotting. Starting from 1.0 version, settings, can be saved directly from the Plot Settings Window.
