Alosa "oligorakered." The multirakered are primarily plankton feeders, the oligorakered have large rakers and are predators, and the medium-rakered generally consume a mixed diet. Most current species of the genus "Alosa" in North America can be found in Florida, whereas the distribution of most of them is broader. Morphology is notoriously liable to adapt to changing food availability in these fish. Several taxa seem to have evolved quite recently, making molecular analyses difficult. In addition, hybridization may be a factor in shad phylogeny. Nonetheless, some trends are emerging. The North American species except the American shad "A. sapidissima" can probably be
Pickled herring fur coat'), which are usually prepared with vegetables and seasoned with mayonnaise dressing. Brined herring is common in Ashkenazi Jewish cuisine, perhaps best known for vorschmack salad known in English simply as "chopped herring" and as schmaltz herring in Yiddish.
