在没有采取海洋保护区（NTMR）的珊瑚礁鱼类的繁殖潜力（每单位面积的产卵量）增加的经验证据是稀疏的。在这里，我们推断的生殖潜力的发展，在两个物种的protogynous礁鱼，绿尾鱼bleekeri（Labridae：Scarinae）和Cephalopholis argus（Epinepholidae），内部和外部的菲律宾NTMR。我们估计了关键的生殖参数，并将其应用于17个NTMR（保护期0-11年）和配对捕捞地点（对照）的物种特异性密度和长度数据，采用空间时间替代方法。对于C. argus，我们还使用的密度和长度数据收集几乎每年超过29年的NTMR和相邻的控制在阿波岛。结果表明，C.在11年的保护后，Bleekerican在NTMR中的生殖潜力是对照的6.0倍，相当于在NTMR中产生500 m− 2的约582，000个卵子。提高了白腹锦鸡儿的繁殖潜力。在11年的时间空间替代中，争论并不明显。在阿波岛NTMR，C。argus在29年中增加了约6倍，但生殖潜力的NTMR/对照比率随着时间的推移而下降（从3.2到2.4），可能是由于C的溢出。argus从NTMR到对照。据估计，在保护的第29年，阿格斯在阿波岛NTMR内的500 m− 2处多产了大约113，000个卵。NTMR与对照的生殖潜力比。布利克里和C. arguswere往往大于相应的比例密度或生物量。该研究强调了物种特异性生殖生活史特征的重要性，这些特征驱动了源于NTMR的幼鱼补贴发展的变化。
Empirical evidence for increases in the reproductive potential (egg output per unit area) of coral reef fish in no‐take marine reserves (NTMRs) is sparse. Here, we inferred the development of reproductive potential in two species of protogynous reef fishes,Chlorurus bleekeri(Labridae: Scarinae) andCephalopholis argus(Epinephelidae), inside and outside of Philippine NTMRs. We estimated key reproductive parameters and applied these to species‐specific density and length data from 17 NTMRs (durations of protection 0–11 years) and paired fished sites (controls) in a space‐for‐time substitution approach. ForC. argus, we also used density and length data collected almost annually over 29 years from a NTMR and an adjacent control at Apo Island. The results suggest thatC. bleekerican develop 6.0 times greater reproductive potential in NTMRs than controls after 11 years of protection, equivalent to approximately 582,000 more eggs produced 500 m−2inside NTMRs. Enhancement of reproductive potential inC. arguswas not evident after 11 years in the space‐for‐time substitution. At Apo Island NTMR, reproductive potential ofC. argusincreased approximately 6‐fold over 29 years but NTMR/control ratios in reproductive potential decreased through time (from 3.2 to 2.4), probably due to spillover ofC. argusfrom the NTMR to the control.C. arguswas estimated to produce approximately 113,000 more eggs 500 m−2inside Apo Island NTMR at the 29th year of protection. Ratios of reproductive potential between NTMR and controls inC. bleekeriandC. arguswere often greater than corresponding ratios in density or biomass. The study underscores the importance of species‐specific reproductive life history traits that drive variation in the development of larval fish subsidies that originate from NTMRs.
