Note
The data is extracted from the game files by a mod for NMS.py created by ThatBomberBoi (Github, Twitter).
This initiative was started by GoodGuysFree shortly after the No Man's Sky Aquarius update added the fishing mechanic. GoodGuysFree started collecting and recording the in-game fishing information with some contributors such as PureCalamity, Lowe Gotembomrek and others. The results of which can be found here.
This work was very tedious and it turned out that the in-game data was not stored in an easy to data mine location in the game files. A collaboration was started with Khaoz-Topsy to integrate the data from the Google Sheet into the web and mobile apps. At that time ThatBomberBoi stepped in and created a NMS.py mod to extract the descriptions created by the game files when inserting a food item into the in-game Bait Box. From this extract we were able to extract the statistics and upload the data into the GoogleSheet maintained by GoodGuysFree, PureCalamity, Lowe Gotembomrek and others.
This project is a collection of the files used to extract the data from the game files, parse the information and then upload the data to the GoogleSheet.
It is worth noting that another contributor to the Google Sheet was Craig Mark who also added his data from his meticulous work which also exists on his web site as an additional sheet (tab).
