Good move by HAL.  We've always enjoyed the fish onboard.....And during our March/April South America cruise, there seemed to be more fish....Delicious.  And I think they were sourcing some along the way.....(You should try it (if you want to)) LOL.    Here is the link to the info just listed on the HAL website....   https://www.hollandamerica.com/en/us/onboard-experiences/dining/fresh-fish?camp=CME:20230920_HEP2342MP3&rmid=20230920_HEP2342MP3&rrid=18964389842&lid
