Local restaurants no longer supplying fish because of fish shortage

In december 2018, some of the local restaurants in panaji, goa were selling fried fish to customers.
The fish was extremely affordable, the customer could ask for fish depending on his or her budget, for Rs 20, Rs 30, or Rs 40 worth of fish.
This was a very good deal, because the customer was saved the trouble of cleaning and cooking the fish.
Many people were purchasing these fried fish, which were available around afternoon.
However in January 2019, the restaurants are no longer selling these fish
The domain investor has enquired repeatedly and a staff said that they are unable to get fish.
