More Than Just a Spawning Location: Examining Fine Scale Space Use of Two Estuarine Fish Species at a Spawning Aggregation Site

Abstract: Many species that provide productive marine fisheries form spawning aggregations. Aggregations are predictable both in time and space and constitute nearly all of the reproductive activity for these species. For species that spend weeks to months on spawning aggregation sites, individuals may need to rely on a forage base at or near the spawning site to balance the high energetic cost associated with reproduction. Here, we ask: do spawning fish with protracted spawning seasons use spawning aggregation sites mo… Show more

“…Therefore, site fidelity at this spawning aggregation indicates that individuals are leaving the site and re turning to spawn at a later time. This temporal movement within the season may be driven by risk avoidance or foraging behaviors (Claydon et al 2012, Becker & Suthers 2014, Boucek et al 2017. The results of inter-seasonal site fidelity over 3 spawning seasons were similar to those seen in 2005, when the spotted seatrout spawning season at Bunces was truncated due to a red tide ).…”

“…Spotted seatrout have traditionally been considered resident spawners that form aggregations within their home ranges and do not migrate to spawn (Walters et al 2007). However, this is not the case at the Bunces FSA site , Boucek et al 2017, which also falls outside of common spawning habitat. Similar behavior has been observed in coral trout, where populations form primary and secondary spawning aggregations (Samoilys 1997).…”

“…Grouper movements.-Movements between receiver locations by tagged grouper were compared and examined for hot spots of activity. We used network analysis to create spatial movement graphs, where nodes represented actual locations of receivers and edges represented the movement of fish between these locations (Finn et al 2014;Becker et al 2016;Boucek et al 2017). Node size was proportionate to node degree (the number of edges connecting to the node), and edge width was proportionate to the total number of times fish moved between receivers.…”

“…1c). These designations were based on productivity, salinity, fish community, and geomorphological differences between the two zones (Boucek et al 2017). The movement patterns of individuals with >50% of their detections occurring in upstream sites were classified as upstream snook, and those with more than 50% detections in the downstream estuarine areas were classified as downstream snook.…”
