I did a quick search and it seems there is some general information out there about ocean farming/aquaculture.

There is a Wikipedia article on the subject:

https://en.wikipedia.org/wiki/Aquaculture

As well as an office of Aquaculture in the US NOAA (National Ocean and Atmospheric Administration):

http://www.nmfs.noaa.gov/aquaculture/index.htm

Maybe these resources could help you find information & resources to learn more about ocean farming/aquaculture.
