Argyrops spinifer and Rhabdosargus haffara are two sympatric seabream species making important contributions to fisheries landings in the western Arabian/Persian Gulf. We identify the strengths and weaknesses in the long-term sustainability of A. spinifer and R. haffara stocks by integrating multiple sources of data, including fisheries catch and effort statistics, life history traits, scientific trawl surveys, and historical length frequency distribution. Four strengths were identified in A. spinifer: wide distribution of juveniles, positive association to the network of de facto fishing exclusion areas created by hundreds of oil-gas facilities, early maturation, and the existence of large and old individuals. A. spinifer suffers from two potential weaknesses: slow growth rate and higher exploitation pressure on the small-sized individuals. R. haffara on the other hand has a strength of having a short life span and a fast growth rate, characteristics that make it robust to unfavorable conditions. R. haffara suffers from two weaknesses: the lack of association to the oil and gas facilities, and the preference for nearshore shallow waters with stronger negative anthropogenic impacts. Identified strengths and weaknesses of these two sparids provided a preliminary assessment about their long-term sustainability, as well as a roadmap about how to develop different management strategies to meet specific objectives.

两种同域海鲷（Argyrops spinifer 和 Rhabdosargus haffara ，Sparidae）长期可持续性的优势和劣势

Argyrops spinifer 和 Rhabdosargus haffara 是两种同域海鲷物种，对阿拉伯/波斯湾西部的渔业上岸做出了重要贡献。我们通过整合多种数据来源，包括渔业捕捞量和努力量统计、生活史特征、科学拖网调查和历史长度频率分布，确定了刺槐和哈法拉河豚种群长期可持续性的优势和劣势。在 A. spinifer 中确定了四个优势：幼鱼的广泛分布、与由数百个油气设施创建的事实上的捕鱼禁区网络正相关、早熟以及大个体和老个体的存在。A. spinifer 有两个潜在的弱点：缓慢的生长速度和对小型个体的更高的开发压力。R。另一方面，haffara 具有寿命短和生长速度快的优势，这些特性使其能够在不利条件下保持健壮。R. haffara 有两个弱点：与石油和天然气设施缺乏关联，以及偏爱具有更强负面人为影响的近岸浅水区。确定的这两种鱼的优势和劣势提供了对其长期可持续性的初步评估，以及关于如何制定不同管理策略以满足特定目标的路线图。以及对具有更强负面人为影响的近岸浅水区的偏好。确定的这两种鱼的优势和劣势提供了对其长期可持续性的初步评估，以及关于如何制定不同管理策略以满足特定目标的路线图。以及对具有更强负面人为影响的近岸浅水区的偏好。确定的这两种鱼的优势和劣势提供了对其长期可持续性的初步评估，以及关于如何制定不同管理策略以满足特定目标的路线图。
