“…Ecological risk assessment has been applied in worldwide in fisheries and natural resource situations (US EPA, 1998;Fletcher, 2005;Smith et al, 2017). Further, it is a component of integrated ecosystem assessment (Levin et al, 2009;DePiper et al, 2017), with examples (Samhouri and Levin, 2012;Fletcher et al, 2016;Newman et al, 2018) as well as frameworks for applying risk assessment within the ecosystem assessment process (Fletcher, 2015;Holsman et al, 2017). However, there are relatively few examples of EAFM risk assessment applications in U.S. and European fishery management.…”

“…Several fisheries management approaches have been introduced to mitigate over-exploitation. However, fisheries management has largely used conventional single-species stock assessment models (Newman et al 2018), which requires data of each species individually (Hilborn and Walters 1992;Cadrin and Dickey-Collas 2015). Consequently, it is impractical to manage each species individually using conventional stock assessment methods in a mixed or multispecies fishery (Shertzer and Williams 2008).…”

Harvest control rules (HCRs) for sustainable fishery management have been developed for data-limited fish species for which stock assessments cannot be conducted. However, HCRs have largely not considered mixed-species catches, as when fishing-effort data are widely pooled for numerous minor species in a multispecies fishery. Presently, a feedback HCR has been successfully applied in Japanese fisheries management. By combining management strategy evaluation with a simulation to generate mixed-species data from a multispecies fishery that assume constant catchability (q) among species, we evaluated the performance of this feedback HCR and then compared its performance using species-specific data. In most cases, the biomass was controlled over that needed for maximum sustainable yield (MSY), and the fishing effort was under the fishing mortality consistent with achieving MSY (FMSY). However, for slow-growing species, the biomass might become lower than what is required to remain capable of producing MSY, even though fishing effort was controlled under FMSY. The results show that the feedback HCR is appropriate for multispecies fisheries management where only mixed-species data are available but with special monitoring for slow-growing minor species.

“…Fishing is one of the main anthropogenic pressures on marine fishes (Arthington, Dulvy, Gladstone, & Winfield, ) and has been found to have greater adverse effects on keystone species in the marine realm (Valls, Coll, & Christensen, ). Potentially associated with the keystone species concept, indicator species are often used in the management of marine ecosystems (Newman et al, ; Robinson et al, ), with these species often being selected based on a suite of ecological and life‐history characteristics (Beauchard, Veríssimo, Queirós, & Herman, ). Incorporating fish species life history and ecological traits, Cheung, Pitcher, and Pauly () used a fuzzy logic system to estimate the intrinsic vulnerability of a given fish species to local extinction, allowing prioritization of species for conservation and management.…”

“…Scalefish fisheries in Western Australian are relatively small and species rich, with limited catch and effort data (Newman et al, ). In some management units, catches by recreational fishers are greater than those of commercial fishers (Newman et al, ). Temperate west Australian fish communities are characterized by high endemism (Ford, Stewart, & Roberts, ; Fox & Beckley, ; Hutchins, ), and endemic marine fish species have been found to be vulnerable to exploitation and habitat loss (Arthington et al, ; Bender et al, ).…”

Aim Understanding the role of interspecific interactions in maintaining diversity, ecosystem function and evolutionary processes is a major challenge in ecology. Historically, antagonistic heterospecific interactions were the focus of many studies, but the importance of facilitative interactions has become increasingly apparent over recent decades. Ecological networks can provide insights into potential interactions among co‐occurring heterospecifics. We compared the structures of temperate and tropical marine fish co‐occurrence networks to estimate their resilience and/or robustness to perturbations. Location Western Australia. Time period Present. Major taxa studied Marine fishes. Methods We compared the structure of temperate and tropical marine fish communities through interspecific co‐occurrences using joint species distribution modelling. Network analyses identified modules of co‐occurring species and those which play a strong role in the organization of communities. Results In all study locations, most interspecific co‐occurrences did not differ significantly from random, with positive co‐occurrences being more prevalent than negative non‐random co‐occurrences. The modularity of networks created from interspecific co‐occurrences tended to decrease poleward, with the opposite for species centrality. An increase in functional diversity among co‐occurring species with latitude was detected. Species centrality was greatest among the temperate endemic species, with a positive association between species centrality and intrinsic vulnerability scores. Main conclusions The differences in community structure between tropical and temperate Western Australian marine fish communities might be attributable, in part, to differing evolutionary histories. The temperate endemic species have co‐evolved in a relatively homogeneous abiotic and biotic environment, whereas the Indo‐Pacific ichthyofauna have evolved in a diverse range of environments. The temperate communities are characterized by: (a) low functional redundancy among co‐occurring species, with endemic species playing keystone roles in community structure; (b) attributes associated with increased vulnerability to perturbations; with (c) many of the species identified as potential keystone species having high intrinsic vulnerability scores and being targeted by fishers.
