Presentation transcript:

Fisheries production estimates

Relationship between fisheries yield and primary production estimates

Relationship between wetland area and shrimp production

Relationship between % marsh vegetation and % brown shrimp caught inshore. Relationship between commercial landings and the ratio of intertidal wetland and open water areas.

Relationship between river discharge and catch (wt) of demersal fishes

Spatial variation in the river discharge and harvest relationship Variation in relationship in wet vs dry years

Positive relationship between relative sea level rise and annual Spartina production Plot of mean sea level rise in SC and TX illustrates spatial differences Morris et al. 1990

Seasonal variation in sea level rise by year. Correlation between landings and sea level rise by area. Morris et al. 1990

Relationship between landings and residuals of sea level rise by year, area and species. Mean sea level rise explains 9-20% of the variability in landings.
