Effect of Egg Sampling Efficiency on Estimates of Historic Striped Bass Egg Production in the Savannah River Estuary, Georgia-South Carolina
The striped bass (Morone saxatilis) population of the Savannah River estuary declined in the 1980s, likely because of the operation of a tide gate that increased salinity on spawning grounds and accelerated seaward transport of eggs and larvae. Following discovery of this negative effect, periodic egg sampling monitored striped bass reproductive effort and documented a 96% decline in egg density (n/100m3) from pre-tide gate levels. The decline in egg density was concomitant with a similar decline in the adult striped bass population. An intensive stocking program eventually restored the...
