The charges against Hing's Chop Suey House stem from a 2013 incident regarding illegally purchased fish.
Conservation Officers had continually informed Owner Gam Hing Choo of purchasing requirements for fish since 2007.
In July last year the MNR inspected the restaurant where they found 22 kilograms of fish stored in bread bags and garbage bags.
Owner Gam Hing Choo said the fish were exchanged with strangers for food from the restaurant.
The MNR confiscated the fish at that time.
The restaurant has been fined 750 dollars for buying fish without a licence.
Meanwhile Choo was fined 250 dollars for illegally buying fish.
