This spring, I booked a trip to a fishing spot in the Champagne region of France. It has a list of the fish in each lake so you can create a “wishlist”. You have no real control over what you catch, but I was after the Carrot. Weighing in at more than 61lb (27kg), she is a monster of a fish and is rarely caught. She is actually a carp, but her bright-orange appearance gave her the nickname of the “world’s biggest goldfish”.
