2016 Post WFTS Transport: AdultSurvival and Egg Rates Reproducible Across 3 Yrs
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 impactdid not affect the comparative adult survival and rates within a given year.There was no statistical difference in adult survival rates between the handcarriage and 40 ft Whooshh tube transport. Egg viability rates were not iinfluenced by environmental conditions and remained very high, >92% across all groups and years. The outcomes support the conclusion that the WFTS is areliable, 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 ameasure 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.
