Final Completion of a Water-Tunnel Respirometer for the Study of Pelagic Marine Fishes

需要资金进行最后的改进和设计更改，以建立作为高功能国家设施的SIO水隧道式呼吸器--“弹性管式呼吸器”。这个设施几乎完全由NSF DMB 85-00261提供的资金建造，是有史以来为生物学研究而建造的最大的循环水隧道，其设计方式允许在海上使用它来研究开放水域的中上层鱼类，如金枪鱼、杰克和某些无法在实验室水族馆中保持健康状态的鲨鱼。仪器现在功能齐全；然而，我们使用它的工作揭示了设计和性能的局限性，可以纠正这些局限性，以实现更好的性能。要求提供完成修改基本结构和业务特点所需的资金。

Funds are requested to make final improvements and design changes needed to establish the SIO water-tunnel respirometer, the "elasmotunatron," as a highly functional national facility. This facility, built almost entirely from funds provided by NSF DMB 85-00261, is the largest recirculating water tunnel ever constructed for biological studies, and has been designed in such a manner to allow its use at sea for research on open-water pelagic fishes such as tunas, jacks, and certain sharks that cannot be kept in healthy condition in laboratory aquaria. The instrument is now fully functional; however, our work with it has revealed design and performance limitations that can be rectified to permit superior performance. Funds required to complete modification of the basic structure and operational features are requested.
