Abstract : Species profiles are literature summaries of the taxonomy, morphology, range, life history, and environmental requirements of coastal aquatic species. They are prepared to assist in environmental impact assessment. The bay anchovy (Anchoa mitchilli) is one of the most abundant pelagic estuarine species and the striped anchovy (Anchoa hepsetus) is a common pelagic estuarine species along the entire coast of the northern Gulf of Mexico. Both fish are important forage species because of their abundance and small size. Striped anchovies may have two major spawning periods (spring and summer), but spawning of bay anchovies probably occurs throughout the year. Length-weight relationships of the bay anchovy and striped anchovy are similar. Zooplankters (especially copepods) constitute the major portion of the diet of both species. Bay anchovies and striped anchovies have been taken from water with temperatures ranging from 4.5 to 39.8 C and 15.0 to 34.9 C, respectively; from water with dissolved oxygen ranging from 1.5 mg/1 to 11.9 mg/1 and 3.0 mg/1 to 8.7 mg/1, respectively; and from water salinity ranging from 0.0 ppt to 45.0 ppt and 0.3 ppt to 44 ppt, respectively. Bay anchovies occur more often at low salinities than do striped anchocies. keywords: Estuaries.
