Alabama shad Alosa alabamae Kingdom: Animalia Phylum: Chordata Class: Actinopterygii Order: Clupeiformes Family: Clupeidae ILLINOIS STATUS common, native FEATURES This species has no lateral line. The scales in the middle of its belly are jagged. An adult Alabama shad may reach 20 and one-fourth inches in length. There are no teeth on the jaws and no scales on the head. The lower jaw is equal to or projects slightly beyond the snout. The lower jaw has dark speckles. Sides and belly are silvery. The back and upper sides are green or blue. The teeth on the tongue are in a single row. There is an adipose eyelid. The body is compressed side-to-side. There are no spines in the fins. The dorsal fin is much farther forward on the body than the anal fin. BEHAVIORS This species lives most of its life in saltwater habitats. It migrates from January through July from the Gulf of Mexico to freshwater rivers and streams to reproduce. It is believed that the juveniles swim to the Gulf of Mexico a few months after hatching. The Alabama shad’s population has been declining in large part due to the construction of locks and dams along large rivers that stop its spawning migrations. Juveniles eat fishes and insects. Adults do not feed when on spawning runs and die after spawning.

Environmental Sensitivity Index Guidelines Version 2.0
NOAA Technical Memorandum NOS ORCA 115 Environmental Sensitivity Index Guidelines Version 2.0 October 1997 Seattle, Washington noaa NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION National Ocean Service Office of Ocean Resources Conservation and Assessment National Ocean Service National Oceanic and Atmospheric Administration U.S. Department of Commerce The Office of Ocean Resources Conservation and Assessment (ORCA) provides decisionmakers comprehensive, scientific information on characteristics of the oceans, coastal areas, and estuaries of the United States of America. The information ranges from strategic, national assessments of coastal and estuarine environmental quality to real-time information for navigation or hazardous materials spill response. Through its National Status and Trends (NS&T) Program, ORCA uses uniform techniques to monitor toxic chemical contamination of bottom-feeding fish, mussels and oysters, and sediments at about 300 locations throughout the United States. A related NS&T Program of directed research examines the relationships between contaminant exposure and indicators of biological responses in fish and shellfish. Through the Hazardous Materials Response and Assessment Division (HAZMAT) Scientific Support Coordination program, ORCA provides critical scientific support for planning and responding to spills of oil or hazardous materials into coastal environments. Technical guidance includes spill trajectory predictions, chemical hazard analyses, and assessments of the sensitivity of marine and estuarine environments to spills. To fulfill the responsibilities of the Secretary of Commerce as a trustee for living marine resources, HAZMAT’s Coastal Resource Coordination program provides technical support to the U.S. Environmental Protection Agency during all phases of the remedial process to protect the environment and restore natural resources at hundreds of waste sites each year.

Endangered Species
FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

IUCN Red List version 2021-1: Table 7 Last Updated: 25 March 2021 Table 7: Species changing IUCN Red List Status (2020-2021) Published listings of a species' status may change for a variety of reasons (genuine improvement or deterioration in status; new information being available that was not known at the time of the previous assessment; taxonomic changes; corrections to mistakes made in previous assessments, etc. To help Red List users interpret the changes between the Red List updates, a summary of species that have changed category between 2020 (IUCN Red List version 2020-3) and 2021 (IUCN Red List version 2021-1) and the reasons for these changes is provided in the table below. IUCN Red List Categories: EX - Extinct, EW - Extinct in the Wild, CR - Critically Endangered [CR(PE) - Critically Endangered (Possibly Extinct), CR(PEW) - Critically Endangered (Possibly Extinct in the Wild)], EN - Endangered, VU - Vulnerable, LR/cd - Lower Risk/conservation dependent, NT - Near Threatened (includes LR/nt - Lower Risk/near threatened), DD - Data Deficient, LC - Least Concern (includes LR/lc - Lower Risk, least concern). Reasons for change: G - Genuine status change (genuine improvement or deterioration in the species' status); N - Non-genuine status change (i.e., status changes due to new information, improved knowledge of the criteria, incorrect data used previously, taxonomic revision, etc.); E - Previous listing was an Error.

Some Atlantic species occur far outside their ilvery, slab-sided, and generically fish-shaped, native ranges, usually in lakes and reservoirs, either from members of the family Clupeidae—herrings, intentional introductions to provide forage for stocked game- shads, sardines, pilchards, sprats, and menhaden fish, or by passage through manmade waterways.1 The S (collectively called clupeids)—are easily overlooked American shad (A. sapidissima) was planted into California’s in favor of more charismatic or distinctively assembled fishes.
