TABLE 3. — Growth data (mm TL) by spawned group for Larimus fasciatus from the Gulf 

 off Freeport, Tex. Night and day cruises are indicated by night (N> and day (D). Observed 

 size ranges delineate spawned group boundaries used in growth and mortality calculations 

 and indicated in Figure 6. Collection dates with asterisks indicate collections pooled to esti- 

 mate mean size at age.
