“…Traditional tempering practices involved slowly exchanging the water in the transfer (stocking) tanks with water from the lake or stream to be stocked [2], thereby allowing for the introduction of foreign organisms into the transfer tank and possibly beyond. By ceasing this water exchange, a possible contamination vector is eliminated, as well as the need for subsequent tank disinfection or anti-invasive species chemical treatments [24][25][26].…”

Hatchery-reared fish are frequently adjusted (tempered) to the higher water temperatures present in the water bodies where they are to be stocked. This study was undertaken to determine the necessity of such tempering practices. This study used rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta) reared at 11.2˚C. The first two trials for each species were designed to simultaneously determine the upper incipient lethal temperature and 100% lethal temperature over a 14-day period. The third trial for each species evaluated the effects of an exaggerated 12-hour tempering regime on fish survival after placement in elevated water temperatures. After transfer from a water temperature of 11.2˚C, no rainbow trout survived at 26˚C, and only 50% survived at 25˚C. No brown trout survived at 22˚C and only 50% at 20˚C. Survival of rainbow trout was not improved by the 12-hour tempering regime where water temperatures were slowly increased from 11.2˚C to either 25˚C or 26˚C. Similarly, tempering did not improve brown trout survival at either 20˚C or 22˚C. These results suggest that tempering is not needed when hatchery-reared trout are reared and stocked at the water temperatures within the range of those used in this study.

“…Additionally, Dreissena veligers have been documented to directly attach to fish (Pucherelli et al. ), which may allow them to bypass a filter system. Therefore, these filter systems would be best utilized on systems where AIS have not been observed and to act as a safeguard against nondetection error.…”

Invasive species represent a substantial threat to aquatic systems, and aquaculture operations provide a vector for their transportation between waters. Moving large volumes of water during fish spawning or trap‐and‐transfer operations increases the risk of transporting invasive bivalve larvae, particularly from sources experiencing nondetection error. This study evaluated the effectiveness of two portable filter systems at reducing or eliminating zebra mussel Dreissena polymorpha and Asian clam Corbicula fluminea veligers from an infested water source. A small setup was assessed at intervals to 1,420 L using combinations of 20‐ and 5‐μm filters arranged in tandem, whereas a large setup was tested at intervals to 7,041 L with combinations of 30‐ and 5‐μm tandem filters operating at two pressure ranges. Zero veligers were observed in 36 small‐setup filtered water samples. Four zebra mussel veligers and zero Asian clam veligers were observed in 60 large‐setup samples. Total zebra mussel and Asian clam counts from 31 unfiltered control samples were 27,846 and 1,095, respectively. Overall, both filter systems were highly effective at removing zebra mussel and Asian clam veligers and represent simple, cost‐effective safeguards against nondetection error of aquatic invasive species in waters used for aquaculture practices.

“…It must be noted that this study did not evaluate the effectiveness of any of the treatment protocols on the control of zebra mussel veligers or adults during actual egg shipment. While the protocols used have been shown to be effective within specific test conditions [6] [20], changes in water temperature, water chemistry, and the density of fish or eggs may influence the ability to kill zebra mussels [21] [22] [23]. Furthermore, the Edwards et al [6] protocols may be less effective against other invasive Dreissenids, such as quagga mussels Dreissenabugensis [22] [23].…”

Several treatment options have been developed to minimize the spread of zebra mussel Dreissena polymorpha veligers (larvae) during fish transportation. However, the effect of these treatments on the survival of newly-fertilized salmonid eggs has not been evaluated. This study examined the survival of water-hardened landlocked fall Chinook salmon Oncorhynchus tshawytscha eggs after one of four different treatments: 1) Control (no chemicals), 2) 100 mg/L formalin for two hours, 3) 750 mg/L of potassium chloride for one hour followed by 20 mg/L formalin for two hours, and 4) 750 mg/L of potassium chloride for one hour followed by 20 mg/L formalin for three hours. The 100 mg/L formalin treatment produced complete egg mortality. Survival to hatch was not significantly different among the other three treatments. Based on these results, the use of 750 mg/L potassium chloride for one hour followed by 20 mg/L formalin for three hours is recommended when moving Chinook salmon eggs from waters potentially infested with zebra mussels to hatcheries for incubation.
