摘要: We calculated the recapture rates for Chinese shrimp Fenneropenaeus chinensis following hatchery release in Jiaozhou Bay and Bohai Bay in 2012 based on parentage identification using simple sequence repeat (SSR) markers. The results and process were as follows: In total, 3 x 10(5) postlarval Chinese shrimp (inner marker), comprising six full-sib families, were released into Jiaozhou Bay with a hatchery release of approximately 9 x 10(7) same-sized stock in the spring. Eight shrimp (inner marker) were identified from 2,507 recapture catches in the autumn, with information about eight SSR loci available by using Cervus 3.0. Similarly, another six full-sib families, comprising 2.04 x 10(5) postlarvae, were released into Bohai Bay with a hatchery release of approximately 1.6 x 10(8) same-sized Chinese shrimp of postlarval stock, and four shrimp were identified from 3,232 recapture catches in the autumn. Furthermore, we calculated the number of released stock in the recapture catches, i.e., 2,400 and 3,137 in Jiaozhou Bay and Bohai Bay, respectively. Combined with statistics for Chinese shrimp resources during the autumn fishing season, we calculated that the recapture rates for Jiaozhou Bay and Bohai Bay were 2.70 and 2.59 %, respectively, being slightly lower but more precise compared with results obtained using traditional methods (2.81 and 2.67 %)
