“…Subsequent literature aimed to determine the least harmful exposure together with the optimal fish responses regarding the physical-chemical characteristics of water (Snyder, 2003). These improvements have permitted to reduce effect of the electric shock (ES) on immediate mortality (Schill & Beland, 1995), but it still has physiological consequences such as haemorrhages or spinal injury (Hollender & Carline, 1994;Sharber et al, 1994;Dalbey et al, 1996;Kocovsky et al, 1997), increasing plasma cortisol, hyperglycaemia, hyperlactataemia (Emery, 1984;Mesa & Schreck, 1989;Bracewell et al, 2004;Matsche et al, 2017) and impaired heart function (Schreer et al, 2004).…”

Adult zebrafish Danio rerio were exposed to an electric shock of 3 V and 1A for 5 s delivered by field backpack electrofishing gear, to induce a taxis followed by a narcosis. The effect of such electric shock was investigated on both the individual performances (swimming capacities and costs of transport) and at cellular and mitochondrial levels (oxygen consumption and oxidative balance). The observed survival rate was very high (96·8%) independent of swimming speed (up to 10 body length s ). The results showed no effect of the treatment on the metabolism and cost of transport of the fish. Nor did the electroshock trigger any changes on muscular oxidative balance and bioenergetics even if red muscle fibres were more oxidative than white muscle. Phosphorylating respiration rates rose between (mean 1 s.e.) 11·16 ± 1·36 pmol O s mg and 15·63 ± 1·60 pmol O s mg for red muscle fibres whereas phosphorylating respiration rates only reached 8·73 ± 1·27 pmol O s mg in white muscle. Such an absence of detectable physiological consequences after electro-induced narcosis both at organismal and cellular scales indicate that this capture method has no apparent negative post-shock performance under the conditions of this study.

ObjectiveThe anadromous American Shad Alosa sapidissima, a once commercially important species in the mid‐Atlantic region, experienced population declines due to overfishing, poor water quality, and impediments to accessing freshwater spawning habitat. Efforts at the regional and national scale substantially addressed the former two obstacles to facilitate population growth, but dam modifications or removal are still ongoing. In 2019, the state of Delaware removed the first barrier to anadromous fish passage on the Brandywine River (a tributary of the Delaware River), Dam 1.MethodsA total of 24 American Shad were surgically tagged with acoustic transmitters from 2021 to 2022 above recently removed Dam 1 and tracked in the Delaware River estuary and coastal waters of the Atlantic Ocean.ResultThe length of available habitat increased by 1.3 km, and 75.0% of surgically tagged American Shad used historic spawning grounds in the Brandywine River following dam removal. Nine individuals exhibited long‐term residency in the Brandywine River from May to June, demonstrating the importance of this newly available habitat to spawning adults. Additionally, one fish returned to the Brandywine River between years, displaying interannual spawning site fidelity and iteroparity. We also observed exploratory behavior of three additional American Shad that exited and returned to the Brandywine River within the same year.ConclusionOverall, we document a successful collaborative network via receiver array maintenance to answer questions regarding anadromous fish migration and habitat use following dam removal.
