“…It has also recently been shown that both Labrids (wrasses) and Sparids were found to significantly increase in abundance within the Broughton Island no-take area compared with only small increases in the Fingal Island notake area (Harasti et al, 2017). Chrysophrys auratus are known to utilize urchin barren habitats (Babcock et al, 1999;Parsons et al, 2014) and given that the Broughton Island no-take area is dominated by Centrostephanus rodgersii urchin barrens, whilst Fingal Island is dominated by kelp Ecklonia radiata (Masens, 2009), it is likely that differing relative abundances between the two locations are influenced by both size and habitats within the no-take areas.…”

“…While adult C. auratus are found on rocky reefs across the continental slope in depths from 5 to 200 m (Curley et al, 2013;Parsons et al, 2014), juveniles are predominantly encountered within coastal embayments and estuaries (Hartill et al, 2004;Poulos et al, 2013). Acoustic telemetry studies have found that C. auratus movement patterns vary based on their size and region.…”

Marine Protected Areas (MPAs) are known to contribute toward the conservation of marine biodiversity, particularly targeted fishery species. Snapper Chrysophrys auratus are an important recreational and commercial fish species in New South Wales (NSW), Australia, and despite fishery management for this species, they are considered "growth overfished" in this region. To assess how C. auratus respond to the implementation of an MPA with several no-take and partially protected areas in temperate NSW, we monitored their populations over a decade (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013)(2014)(2015)(2016)(2017) using baited remote underwater video systems (BRUVs). Surveys were conducted in the Port Stephens-Great Lakes Marine Park with BRUVs deployed on rocky reefs in depths of 20-50 m. Long term seasonal sampling (winter vs. summer) was undertaken at two locations (Broughton and Fingal Island), and changes in C. auratus abundance prior to, and 8 years after zoning implementation, were assessed between these two locations. In total, we sampled five no-take areas within the marine park and five comparative nearby partially protected fished areas and three sites located outside the marine park boundaries. The most pronounced changes in abundance and size structure for C. auratus were observed in the Broughton Island no-take area where numbers increased almost 3-fold (2.91 times) over 8 years of protection. Relative abundance showed seasonal variation at two locations, and we consistently recorded increasing abundance within no-take areas at Broughton and Fingal Island compared to nearby sites open to fishing. Surveys across the five no-take areas found a significant increase in the abundance of C. auratus, whilst the five partially-protected locations in the marine park still recorded higher abundances than sites outside the marine park. In addition, length measurements from stereo-BRUVS indicated that C. auratus were significantly larger in no-take areas compared to partially-protected areas in the marine park and sites outside the marine park. This study demonstrates how the implementation of the marine park and the protection afforded by no-take and partially-protected areas provides refuge for this important fishery targeted species.

“…Some fisheries are also subject to seasonal closures. In New Zealand, weather conditions are usually more conducive to fishing during the summer months, when several popular species spawn close inshore where they become more vulnerable to recreational fishers (Parsons et al, 2014). Non-cyclical inter-annual fluctuations between El Nino and La Nina conditions of varying degrees can also have a marked influence on levels of fishing effort and fisher success (Zúniga Flores et al, 2008).…”

“…However, it was difficult to make any generalised inferences about the actual predation on benthic crustaceans without greater knowledge of their seasonal changes in spatial arrangement and the distinct predatory behaviour during different development stages for individual fish species. The small spatial scale of the sampling area in this study limited the observations on large-scale fish migrations (Gust et al 2001;Parsons et al 2014). For example, snapper were detected as dominant species in all samples, except for the night-time sampling in spring/summer but the study could not identify seasonal variations in their abundance.…”

“…Likewise, the overall measure of species richness did not vary among the seasons that were sampled. However, despite the overall measures remaining similar among seasons, variations in the presence and abundance of individual species generated a seasonal variation in fish assemblages, which was most likely driven by changes in water temperature and by ontogenetic changes in behaviour by individual fish species (Hyndes et al 1999;Parsons et al 2014). Ontogenetic changes in abundance or behaviour of benthic predators were not measured in this study because detailed size measurements of individual fish were not possible.…”

Fish assemblages that included known predators of benthic crustaceans were compared between kelp and barren habitats in northeastern New Zealand using baited underwater video census methods. The benthic-feeding fish were observed in winter, spring/summer and autumn, as well as during night-time in spring/summer. Overall, the fish assemblages varied between barren and kelp habitat, being most marked in winter. Individual benthic-feeding species, such as grey mao mao (Scorpis lineolatus) and leatherjacket (Meuschenia scaber) were associated with barren habitat, while the spotted wrasse (Notolabrus celidotus) was more strongly associated with kelp habitat. The results suggest that changes in habitats on coastal reefs affect populations of species that are benthic predators, which may in turn influence the distribution and abundance of their prey species, such as juvenile spiny lobsters.
