Alosa aestivalis

(Blueback Glut Herring)

Overview

[ Back to top ]

Family : Herrings , shads , sardines , menhadens ; Form schools and possibly wintering near the bottom and out from the coast, approaching the shore in the late spring . Feed on small fishes , copepods and small shrimps. Spawn in brackish- or freshwaters of rivers , arriving in coastal waters a month or so later than A. pseudoharengus (in April at Chesapeake Bay , apparently when the water is above 70¦ C and later further north). Eggs are essentially pelagic, demersal in still water [1]. Larvae are found in fresh and brackish rivers[1]. Juveniles leave fresh and brackish nursery grounds at about 5 cm, migrating downstream [1]. Marketed mostly fresh and salted[2]. Parasites found are acanthocephalan and nematodes [3].

Description

[ Back to top ]

Family Clupeidae

Distribution: global (mostly tropical ) from 70° N to about 60° S. Chiefly marine coastal and schooling fishes ; some freshwater and anadromous . Body usually fusiform , round to strongly compressed . Head without scales ; jaw teeth, when present, are small or minute. A single dorsal fin, small and near midpoint of body; pelvic fins more or less below dorsal fin base ; dorsal and pelvic fins absent in some species; soft rays only. Lateral line spanning a few scales behind the head in some species, missing in others; scales cycloid (smooth to touch); abdominal scutes usually present (a single pelvic scute in the Dussumieriinae). Branchiostegal rays usually 5-10. Most feed on small planktonic animals. Size range (adults ): from 2 to 75 cm. One of the most important family of commercial fishes, processed for food, oil , or fish meal .The family Clupeidae belongs to the Class Actinopterygii (ray-finned fishes) and the Order Clupeiformes. It contains 66 genera and 216 species. It may be found in Marine, Brackish , and Freshwater environments and is primarily Marine. Members of this family are not used in the aquarium trade. Reproductively, most members of this family are nonguarders. The main mode of swimming of adult fish in this family is carangiform . Compared with other fish, the activity level of this family tends to be normal. Members of this family have been dated back to the lower Eocene epoch of the Tertiary period. This family may be found from 70° n to 55° s and 180° w to 179° e. Etymology of this family name : Latin, clupea = sardine, derived from Clupeus = shield ; doubtless a reference to the scales covering the body of the fish + Greek, odous = teeth
