“…A comparison of implantation methods found significantly reduced wound healing for fish tagged by incision compared to syringe [38]. Wound healing is not measured in all tagging studies [5,13,14,30,32,36,[39][40][41][42] (Additional file 2) and may not always be indicative of ill effects of tagging. However, wound healing should be monitored in the interest of fish welfare and ensured that the wound has no significant impact on survival, tag retention, growth, condition and general health.…”

Assessment of PIT tag retention, growth and post-tagging survival in juvenile lumpfish, Cyclopterus lumpus

Background: Passive integrated transponder (PIT) tags are used to study the movement and behaviour in populations of a wide variety of fish species and for a number of different applications from fisheries to aquaculture. Before embarking on long-term studies, it is important to collect information on both short-and medium-term survival and tag retention for the species in question. In this study, 90 juvenile lumpfish (10-20 g, 30 fish per replicate tank) were implanted with 12.5-mm FDX PIT tags. Results: Tag retention, growth rates and survival were compared to those of fish subjected to handling only (90 fish, 30 per replicate tank). Overall survival was 100% during the 28-day monitoring period, and tag retention was 99%. Conclusions: Results indicate that retention rates of 12.5-mm PIT tags in juvenile lumpfish are high, and there is no significant effect on growth rates or survival in a hatchery environment.

“…Although there is a paucity of information regarding the movements of Australian small-bodied freshwater fishes, studies on ephemeral waterholes and genetics (Unmack, Allen & Johnson, 2013) suggest that some of these species are capable of dispersing great distances. The study of dispersal in small-bodied fishes has often been hampered by their size and the consequent limitations in employing individually tagged fish (Allan et al, 2018).…”

The translocation of species outside their natural range is a threat to aquatic biodiversity globally, especially freshwater fishes, as most are not only susceptible to predation and competition but readily hybridize with congeners. Running River rainbowfish (RRR, Melanotaenia sp.) is a narrow‐ranged, small‐bodied freshwater fish that recently became threatened and was subsequently listed as Critically Endangered, owing to introgressive hybridization and competition following the translocation of a congeneric species, the eastern rainbowfish (Melanotaenia splendida). To conserve RRR, wild fish were taken into captivity, genetically confirmed as pure representatives, and successfully bred. As the threat of introgression with translocated eastern rainbowfish could not be mitigated, a plan was devised to translocate captive raised RRR into unoccupied habitats within their native catchment, upstream of natural barriers. The translocation plan involved careful site selection and habitat assessment, predator training (exposure to predators prior to release), soft release (with a gradual transition from captivity to nature), and post‐release monitoring, and this approach was ultimately successful. Two populations of RRR were established in two previously unoccupied streams above waterfalls with a combined stream length of 18 km. Post‐release monitoring was affected by floods and low sample sizes, but suggested that predation and time of release are important factors to consider in similar conservation recovery programmes for small‐bodied, short‐lived fishes.

“…There is a paucity of movement data for most smaller species (,150-mm total length; e.g. olive perchlet, southern pygmy perch and Murray hardyhead), not just due to size-related limitations of tagging methods (but see Allan et al 2018), but also because they generally receive less attention than largerbodied species (Saddlier et al 2013;Lintermans et al 2020). However, when studies have occurred, large numbers of individuals of many small species have been found to move (Stuart and Berghuis 2002;.…”

“…This can be used together with otolith microchemistry to determine natal origin and life-history movement patterns (Zampatti et al 2018(Zampatti et al , 2019. Further use of passive integrated transponders (Allan et al 2018), acoustic and radio tags (Adams et al 2012;McKenzie et al 2012), with accompanying remote data collection, can enhance our understanding of connectivity as a key population process over multiple spatial and temporal scales. Otoliths can also be used to determine a range of life-history traits (see Starrs et al 2016) and responses to environmental change (e.g.…”

Many freshwater fishes are imperilled globally, and there is a need for easily accessible, contemporary ecological knowledge to guide management. This compendium contains knowledge collated from over 600 publications and 27 expert workshops to support the restoration of 9 priority native freshwater fish species, representative of the range of life-history strategies and values in south-eastern Australia’s Murray–Darling Basin. To help prioritise future research investment and restoration actions, ecological knowledge and threats were assessed for each species and life stage. There is considerable new knowledge (80% of publications used were from the past 20 years), but this varied among species and life stages, with most known about adults, then egg, juvenile and larval stages (in that order). The biggest knowledge gaps concerned early life stage requirements, survival, recruitment, growth rates, condition and movements. Key threats include reduced longitudinal and lateral connectivity, altered flows, loss of refugia, reductions in both flowing (lotic) and slackwater riverine habitats, degradation of wetland habitats, alien species interactions and loss of aquatic vegetation. Examples and case studies illustrating the application of this knowledge to underpin effective restoration management are provided. This extensive ecological evidence base for multiple species is presented in a tabular format to assist a range of readers.
