Pike-perch or zander. It is a river fish with delicate flavour. They can be differentiated from the perch by the relatively large space between their dorsal fins and their elongate, fusiform body, which is never so steeply arched behind the head as it is in the Perch. The flesh is firm and white with a stronger flavour than cod. It was introduced into the United Kingdom in the 70's and is in danger of wiping out native species of fish.
Brown shrimp. A small, common shrimp which grows up to 6 cm (2½ inches) long, has a soft shell and turns greyish-brown when cooked. It is found on sandy shores. It has excellent flavour.
Crow garlic. A form of garlic which is more a weed than a culinary gift. It's aftertaste is relatively bitter, and it imparts a garlic flavour to the meat of animals which graze wehre it is prevalent. It is invasive in some areas.
"St Peter fish." John Dory. A high quality, plump, flattish fish with a golden sheen, with an ugly but amiable face. It was first associated with Zeus, then with St Peter, as evidenced by the ‘finger marks’ left by him when he picked it up to remove a coin from its mouth to pay some taxes. It is also plaice.
