Abstract

The fan mussel Pinna nobilis is experiencing a mass mortality event throughout the Mediterranean Sea. The survival of the remaining isolated populations and the maintenance and reproduction of individuals in captivity could determine the future of the species. This paper examines the clearance rate (CR) and oxygen consumption (VO2) of fan mussel individuals measured under 5 different temperatures (8.5, 14, 18, 23 and 28ºC). The measurements of both physiological variables revealed a threshold limit of thermal tolerance at both extreme temperatures, indicating the critical situation of the remaining populations, which are located in coastal lagoons and shallow bays where these extreme temperatures usually occur. Besides, the high clearance rates observed highlight the significant ecosystem service provided by the species in terms of water filtration, especially in confined waters with low renewal rates. Routine control of the clearance rate as an early warning system is proposed for detecting ailing individuals. Such a system could also be used to improve captivity conditions.

扇贝对温度的生理反应:生态学和圈养意义

扇形贻贝正经历着整个地中海的大规模死亡事件。剩余孤立种群的生存和圈养个体的维持和繁殖可能决定该物种的未来。本文研究了在8.5、14、18、23和28℃5种不同温度下扇贝个体的清除率(CR)和耗氧量(VO2)。这两个生理变量的测量结果显示了在这两种极端温度下的热耐受性阈值，表明剩余种群的临界情况，这些种群位于沿海泻湖和浅海湾，这些极端温度通常发生。此外，观察到的高清除率突出了该物种在水过滤方面提供的重要生态系统服务，特别是在更新速度较低的封闭水域。提出了一种常规控制清除率的预警系统，用于检测患病个体。这样的系统也可以用来改善圈养条件。
