Figure lO. — Observed and predicted sizes at age of Cynoscion arenarius from the gulf off Freeport and Port Aransas, Tex., 

 for spring spawned fish and late summer spawned fish. Modal sizes (Shlossman 1980. tables 1, 2) were regressed on ages after 

 assigned hatching dates. Regression was significant at a = 0.01.
