Question: Do fall Chinook salmon travelling through a 40' or a 250' Whooshh fish transport system incur additional physiological stress compared to the trap and haul transport or control-net transport fish?

Conclusion:  No. There was no significant difference in elevated immune response levels among the study groups measured 2-3 days post-transport. Additionally, there was no indication of a difference in female cortisol levels, as an indicator of stress, attributable to the Whooshh Fish Transport System experience.

Question: Will fish experience any extraordinary, potentially harmful, G forces when travelling through the Whooshh fish transport system?

Conclusion: No. The instantaneous G forces experienced by fish going through the Whooshh system are overall quite low.  They are less than half the G force a fish experiences when falling back into the water either onto its belly or backwards from a 36 inches height, which is a scenario typically experienced when fish are discharged from a truck in a trap and haul operation or down and out a fish slide where the fish do not re-enter the water head first.

Question:  Will Lake Sturgeon safely transport through the Whooshh fish transport system?

Conclusion: Yes. There was no indication of external injury to study fish caused by passage through the Whooshh Fish Transport System. No mortalities occurred in the study: Whooshh and control transport groups. These results support the potential of the Whooshh system as a viable method for sturgeon passage upstream or downstream at dams.

Question: Is it feasible to safely, efficiently and effectively transport salmon 1,100 ft distance with a 100 ft elevation via the Whooshh Fish Transport System?

Conclusion: Yes. In the summer of 2016 58 late spring summer Chinook were transported via WFTS 1,100 ft with a100 ft elevation in ~35 seconds with controlled deceleration into a hatchery truck.  The fish were hauled to Cle Elum hatchery and observed for adult survival until ripe for harvest (1-3 months )and egg viability. Comparisons of adult survival and egg viability were drawn between the 1,100 ft WFTS Chinook and ~85 ft hand carriage or 40 ft Chinook groups.  No difference in adult survival or egg viability was observed between the groups.

Question:  Comparing hand carriage vs 40 ft Whooshhtransport followed by hatchery truck haul are the adult survival and eggviability rates comparatively reproducible? An evaluation of three-years worthof data.

Conclusion: Yes. Although the environmental conditions varied considerably across the three years of study (2014, 2015 and 2016), the impact did not affect the comparative adult survival and rates within a given year.There was no statistical difference in adult survival rates between the hand carriage and 40 ft Whooshh tube transport. Egg viability rates were not influenced by environmental conditions and remained very high, >92% across all groups and years. The outcomes support the conclusion that the WFTS is are liable, durable, viable alternative to the standard hand-walking transport method from the fish safety perspective and provides a reduced risk benefit to the fish of damage due to accidental dropping. From the fish handler perspective, the WFTS is easy to use, fast, may reduce potential fish injury, and adds a measure of safety for the fish handler. The results of this comprehensive comparative study strongly endorses the recommendation of WFTS use for safe transport of live fish.

Question: Does the Whooshh Fish Transport System (WFTS)  provide for better fish welfare (less stress on the fish) as compared to aqua pumps or hand carriage handling?

Study Plan: PDF

Conclusion: The WFTS itself does not impose stress, behavior or other welfare concerns on the fish. Attention must be paid to other transfer processes to minimize stress pre-Whooshh transport.

Question: The sorting by species and passage efficiency of Chinook salmon (Oncorhynchus tshawytscha)  and steelhead (O. mykiss) through the WESS-WFTS was assessed.

Conclusion: PNNL found that the WESS-WFTS was able to sort the fish by size, few fish had external injuries, and few unexpected events (e.g. backward transport, discontinuous transport) occurred. PNNL results support the use of the WESS-WFTS as an effective transport system for adult salmonids when used in conjunction with a volitional fishway entrance.

Question: What design features are incorporated into the Elverator, floating elver trap, and how well does it perform?   

Conclusion: Floating design, EF-16 climbing substrate, covered, water delivery to climbing substrate, supplemental attraction flow, and collection vessel location, all contribute to a successful design.  The Elverator outperformed, in number of elver collected, when compared to a conventional ramp trap in a study on River Lagan, Sweden in 2016 and three conventional pipe traps on River Gota alv, Sweden in 2018.  In addition, the Elverator collected a greater range of elver sizes.

Question: How do three different elver climbing substrates compare?   

Conclusion: The stubbed substratum, EF-16 climbing substrate, demonstrated “superior performance” in attracting more elver approaches, initiating more climbs and the elver traveled measurably faster up the studded substratum in contrast to either the bristle or open weave substratum. “To recover endangered migrating species, enhancing the performance of passage solutions at barriers between habitats is a critical factor.”
