Table 1. — Summary of 1986 mark-recapture experiments with brown shrimp and pink shrimp off Tamaulipas and 

 Texas. Recaptures include all shrimp, regardless of the quality of return information, caught as of 5 December 1986, 

 the date of last recapture. 



Table 2.— Comparison of shrimp species compositions for release, for all recaptures regardless of quality of return 

 information, and for recaptures with complete and accurate return information. The latter group formed the data 

 base for analyses of directional movement. N = number examined, ' = significant difference (Mest, a = 0.05) 

 between proportions of brown shrimp released and recaptured (all recaptures excluding unknowns).
