I serve on the Black Bass Advisory Committee for Maryland and recently we were able to get a voluntary donation option added to COMPASS where fishing licenses, etc. are purchased.
Now you can make a donation to this fund through COMPASS (https://compass.dnr.maryland.gov/CustomerAccountHome/ProductCatalog/Product/ListAllFilteredProducts/836214?area=ProductCatalog) any time.
Log in to COMPASS, go to Purchase Merchandise, and click on the Merchandise section to find the Black Bass Conservation Fund option.
These funds are used to purchase bass for remediation stocking, structures for enhancing aquatic habitat, and supplies awarded to directors of black bass tournaments (https://dnr.maryland.gov/fisheries/pages/bass/bass-conservation.aspx).
