“…Timing of SNS spawning in the Saint John estuary was slightly later than in the upper Connecticut River; Taubert and Reed (1979), took SNS eggs and larvae during the first 2 weeks of May in 1977 and 1978 when water temperatures averaged 12°C. Further south in the Delaware River, Meehan (1910) reported SNS were running ripe in midApril.…”

Duringa 4-year study, 4178 shortnose sturgeon were capturedand 2453 marked withnurnhered tags and released. For adults, Z was estimated as 0.12-0.15 and F was estimated as 0.01. The population weight-length relationship was log W = 3.21 (log FL,) -5.45, where W = weight in kilograms and FL = fork length in cm. The oldest female was 67 years; the oldest male was 32 years. Von Bertalanffy growth parameters L,, W,, and K were 127.0 cm, 24.8 kg, and 0.047 for females. and 108.7 cm, 13.9 kg, and 0.063 for males. Sex ratio ofadults was 2.

“…The shortnose sturgeon's endangered species status has stimulated recent investigations that have shown it to be more abundant in some drainage systems than had been known previously (Brundage and Meadows 1982). Reproducing populations have recently been studied from Canada to Georgia (Marchette and Smiley 1982;Heidt andGilbert 1978, Brundage andMeadows 1982;Dadswell 1979a and b;Dovel 1978;McCleave et al 1977;Squiers and Smith 1978;Taubert 1980a and b;Taubert and Reed 1978).…”

“…In northern rivers, the spawning grounds are in regions of fast flow (40 to 60 cm/sec[1.3 to 2 ft/sec]) with gravel or rubble bottoms (Taubert 1980a and b;Buckley 1982;Pekovitch 1979). This apparently has been confirmed for the Savannah River population (Hall et al 1991).…”

Shortnose sturgeon (Acipenser brevirostrum) populations were decimated by a variety of anthropogenic activities throughout much of the 20th century. Understanding the spatial and temporal dynamics of spawning migrations within natal rivers is a critical information gap with regard to habitat protection and ultimately, species recovery.The objectives of this study were to document and describe seasonal movements of shortnose sturgeon in the Altamaha River system, Georgia. Passive acoustic telemetry was used to monitor the movements of 40 adult individuals from April 2011 through February 2014. Telemetry data revealed that during much of the year, the adults resided within the tidally influenced portion of the river, with most detections occurring near the freshwater-saltwater interface. Upstream movements to potential spawning habitat occurred during winter and early spring, and most fish returned to the lower estuary by April. Upstream migrations appeared to be triggered by environmental cues and were initiated when mean weekly temperatures in the lower Altamaha River were 11.6-16.9°C. Unlike spawning migrations documented in northern rivers, the pattern of movement observed in this study was a single-step migration without an apparent resting or staging period. Upstream migrations during nonspawning months were also observed and appeared to correspond with increasing discharge, which potentially resulted in increased channel navigability and habitat availability in nondrought years. This study further illustrates the clinal variations in life history typical of the species and may have important implications on river-specific strategies for species recovery.
