In 1997 and 1998, 1,302 striped bass were marked with anchor tags with return rewards of $10 and $100 to assess non-reporting.

A portion of these fish were double tagged to assess tag loss.

Short-term mortality due to tagging was assessed and was negligible.

For both years combined, the recapture rate was estimated as 38%, providing an estimate of fishing mortality.

In a separate evaluation, a catch curve was generated from experimental gill netting conducted in December-February over the past decade.

Total mortality was estimated at 0.65 per year, indicating a natural mortality of 0.27/year, which is considerably higher than the 0.15/year assumed in previous evaluation efforts.

If this value is accurate, it would have important management implications.
