Recapture frequencies ([number recaptured/number re- 

 leased] x 100% (±SEM]) of cultured striped mullet juve- 

 niles released in 1992 and subsequently collected over 11 

 months at four nursery habitats in Kaneohe Bay. Combined 

 data for fish from both spring and summer releases (n=6 

 lots) are presented and compared over the five size-at-re- 

 lease intervals: interval 1 = 45-60 mm, 2 = 60-70 mm, 3 = 

 70-85 mm, 4 = 85-110 mm, and 5 = 110-130 mm total length.

Recapture frequencies ([number recaptured/number re- 

 leased] x 100% [± SEM]) following spring releases (n=3 

 lots) of cultured striped mullet juveniles in 1992. These 

 are combined data from four nursery habitats sampled in 

 Kaneohe Bay. Data are plotted against size-at-release in- 

 tervals, which are explained in the legend for Figure 5. 

 Data are for the period from 16 weeks after release through 

 the end of the study.

Recapture frequencies ([number recaptured/number re- 

 leased] x 100% [± SEM]) following summer releases (n=3 

 lots) of cultured striped mullet juveniles released in 1992. 

 Size-at-release intervals are explained in Figure 5. No fish 

 in the two smallest intervals were released in summer 

 1992. Data from the four nursery habitats are combined 

 and are for the period from 16 weeks after release through 

 the end of the study.

Comparison of spring and summer recapture frequencies 

 of cultured striped mullet for the period from 16 weeks 

 after release through the end of the study. No fish in the 

 two smallest size intervals were released in summer. Data 

 from the four nursery habitats are combined. Size-at-re- 

 lease intervals are explained in Figure 5.
