Proof-of-concept test of a differential pressure system to transport great lakes fishes

RATIONALE: An emergent fish transport technology, Whooshh Fish Transport System (WFTS), has demonstrated successful, automated passage for salmon spp. (Bryan, 2015, Yakima Nation Fisheries 2014) with minimal impact on fish health (Geist et al. 2016; Mesa et al. 2013). The WFTS transports fish using a pressure differential (positive pressure downstream and negative pressure upstream) to create a motive force that acts upon the effective surface area (circumference) of a fish inside closed, flexible tubes. Fish with greater surface area to weight ratios require lower pressure differentials to be transported through the low friction tube environment. The efficacy of WFTS to transport Great Lakes migratory species. We hypothesize that the fusiform shape of most Great Lakes Migratory species will allow transport through the WFTS with a lower pressure differential than would be required to transport anguilliform sea lamprey. Given the potential for automated sorting and passage, WFTS could become a useful selective passage tool in the Great Lakes to pass valued fishes and block sea lamprey, where traditional trap and sort systems are often too labor intensive and expensive to implement broadly. Here, we propose a proof-of-concept study to test the efficacy of the WFTS at transporting fish representing a range of circumference:weight ratios that might be expected in a Great Lakes tributary, including smallmouth bass, rainbow trout, walleye, white sucker, northern pike, and sea lamprey.
OBJECTIVES: Determine if fusiform Great Lakes migratory fish are transported through WFTS while anguilliform sea lamprey are simultaneously not transported.
