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
Fish Hook River Fish Hook River The Fish Hook River, also spelled Fishhook River, is a tributary of the Shell River, long, in north-central Minnesota in the United States. The river's source, Fish Hook Lake, collects short tributaries known as the Portage River and the Potato River. Via the Shell and Crow Wing rivers, the Fish Hook River is part of the watershed of the Mississippi River. The river flows for its entire length in southwestern Hubbard County; its watershed extends into northeastern Becker County. Its name is a translation of the Ojibwe name for the river and Fish Hook Lake, "Pugidabani". The
