If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/fish
%  sudo port install fish  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching fish
--->  Verifying checksum for fish
--->  Extracting fish
--->  Configuring fish
--->  Building fish with target all

--->  Staging fish into destroot

--->  Installing fish

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using fish with these commands:

%  man fish
%  apropos fish
%  which fish
%  locate fish
