2011  Physiological Response Study

QuestionHow do the physiological responses compare between groups of hatchery adult rainbow trout Oncorhynchus mykiss after traveling through an early prototype of the Whooshh Fish Transport System (WFTS) or by trap and haul transport?


Conclusion:  The results indicated that fish that were passed through the Whooshh Fish Transport System were not severely stressed or injured from the Whooshh tube experience when compared to trout that were transported by trap and haul.

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.

2016 Post WFTS Transport: Adult Survival and Egg Rates Reproducible Across 3 Years

Question:  Comparing hand carriage vs 40 ft Whooshh transport followed by hatchery truck haul are the adult survival and egg viability rates comparatively reproducible? An evaluation of three-years worth of 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.

2017 Evaluation of Volitional Entry, Sorting and Passage of Adult Pacific Salmonids Through a Novel Fish Passage Technology

QuestionThe 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.

2017 American Shad: Transport Feasibility Study

Question: Is it feasible to transport American shad via a Whooshh fish transport system? What is the associated passage survival and impact on the epithelium associated with Whooshh passage? 


Conclusion: Yes, it is feasible to safely, efficiently and effectively transport via Whooshh fish transport system.  Comparing fluorescein dye staining for epithelial injury, it was found that the level of staining was very low indicating very small or limited injury, the patterns being consistent with study-associated fish handling, and no differences were found between the non-transported shad and the WFTS-transported shad.  Immediate survival post-WFTS transport was 100% and 24 hour survival of shad was 97.4% excluding the few shad that were injured due to correctable technical setup complications encountered for the temporary installation

2017 Evaluation of a Novel Floating Elver Trap

Question: How does a floating elver trap compare to a stationary elver trap?


Conclusion: The floating elver trap caught elver in both dark (night) and light (daytime) hours whereas the stationary trap only caught elver in dark hours.  Across three separate trial pairwise comparisons, the floating trap caught significantly more elver (Lagan night Z=" 2.52," p=" 0.012," Lagan day Z="2.81," p="0.005" and Atran night Z="2.81," p="0.005)." The design features of the mobile floating trap with wide and limited length ramps along with directed attraction flow facilitated elver attraction, ramp entry and collection.  The floating covered structure also produced a dark shaded environment which likely facilitated collection during daylight hours.

QuestionWhat 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 well does the new floating collector compare to conventional elver pipe traps at Lilla Edet?


Conclusion: The single floating collector caught 58-65% of the total elver collected during each of the three time periods assessed, the remainder of the elver were caught via a combination of three conventional pipe traps.  Thus, the single Elverator trap outperformed three pipe traps.  In addition, the Elverator accommodated a greater range in elver sizes, facilitating increased capture and species diversity.

QuestionHow 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.”

Conclusion

Yes, it is feasible to safely, efficiently and effectively transport via Whooshh fish transport system. Comparing fluorescein dye staining for epithelial injury, it was found that the level of staining was very low indicating very small or limited injury, the patterns being consistent with study-associated fish handling, and no differences were found between the non-transported shad and the WFTS-transported shad.  Immediate survival post-WFTS transport was 100% and 24 hour survival of shad was 97.4% excluding the few shad that were injured due to correctable technical setup complications encountered for the temporary installation.

​2017 Evaluation of a Novel Floating Elver Trap

The Question

How does a floating elver trap compare to a stationary elver trap?

Conclusion

The floating elver trap caught elver in both dark (night) and light (daytime) hours whereas the stationary trap only caught elver in dark hours.  Across three separate trial pairwise comparisons, the floating trap caught significantly more elver (Lagan night Z=" 2.52," p=" 0.012," Lagan day Z="2.81," p="0.005" and Atran night Z="2.81," p="0.005)." The design features of the mobile floating trap with wide and limited length ramps along with directed attraction flow facilitated elver attraction, ramp entry and collection.  The floating covered structure also produced a dark shaded environment which likely facilitated collection during daylight hours.
