Understanding the life histories of amphidromous fish by integrating otolith‐derived growth reconstructions, post‐larval migrations and reproductive traits

Abstract: 1. Amphidromy is the most prevalent type of diadromous migration. Despite this, the conservation and management of amphidromous species is exceptionally challenging because this life history type, with larval development in a pelagic habitat (usually marine) and adult development in fresh water, is poorly resolved.2. The chronological properties of otoliths, together with a spatial and temporal analysis of post-larval migration traits and adult reproductive traits, were used to reconstruct the life history of … Show more

“…We chose to monitor post-recruit (late juvenile and adult) demography because larval and post-larval stages of G. maculatus occur at sea, are largely unknown and challenging to monitor. Furthermore, post-recruit demography may inherently reflect the demography of early life stages [ 29 ] and consequently their survival to adulthood.…”

“…Egan, Hickford, & Schiel () consider the inter‐relationship between marine and freshwater phases of the amphidromous Galaxias maculatus (Jenyns, 1842) an ‘At risk’ species of Galaxiidae that is harvested seasonally as upstream migrating larvae. Using otolith analysis, they reconstructed early growth histories and found that hatch season affected marine growth rates, suggesting that migrants arriving early in fresh water have the potential for higher reproductive output.…”

“…Therefore, assessing the contributions of these areas, and the connectivity between populations, is necessary for efficient restoration (Jansson, Nilsson & Malmqvist, 2007; Zeigler & Whitledge, 2010). Moreover, identifying spawning areas and migration patterns will help with a better understanding of the species' life‐history traits, which is a central goal in any species conservation strategy (Takada & Tachihara, 2009; Egan, Hickford & Schiel, 2019).…”
