The potential reproduction will be investigated of both released and wild individuals in second year. And studying how to enhance the survival rate of released fry will be done in third year. The aim of this year (the second year) includes (1) continuing to collect and study the recovering data, (2) preparing the reproductive data for both released and wild individuals, and (3) comparing the potential fecundity for both stock.成熟產卵孕卵數黑鯛MaturitySpawningFecundityBlack porgy沿近海漁業資源合理利用及管理之研究-魚苗放流後之成長、存活率與放流效益之評估
