“…We recognize the challenges associated with maintaining this information at high resolutions in more biodiverse regions, especially given resource limitations and ongoing efforts to strengthen relationships among management and fishing communities (Jokiel et al 2011;Matos-Caraballo and Agar 2011;Kittinger et al 2015). However, enhanced monitoring, outreach, refined stock evaluation frameworks, and the incorporation of socioeconomic information are improving data accuracies and assessment potential in the U.S. and broader Caribbean (Ault et al 2008;Narozanski et al 2013;Cummings et al 2015;Gill et al 2017), Pacific Islands (Jokiel et al 2011;Nadon et al 2015), and other data poor international regions (Dowling et al 2015;Newman et al 2015Newman et al , 2017. Additionally, many of the systematic, aggregate metrics noted above (i.e., various ratios) are readily estimable from extent data streams.…”

To implement ecosystem-based fisheries management (EBFM), there is a need to comprehensively examine fundamental components of fisheries ecosystems and ascertain the characteristics and strategies facilitating this more systematic approach. Coupled natural and human factors, inherent biological productivities, and systematic governance measures all influence living marine resource (LMR) and socioeconomic status within a given socio-ecological system (SES). Determining the relative prominence of these factors remains a challenge. Examining these facets to determine how much EBFM and wise LMR management occurs is timely and warranted given the many issues facing marine fisheries ecosystems.

“…Perhaps the radically different growth estimates and maximum ages may be due to differences in fishing pressure or different sampling designs (Chang et al 2019;Goodyear 2019) among locations. It also may be related to the otolith preparation methods and aging criteria used (Newman et al 2015(Newman et al , 2016(Newman et al , 2017. Then et al (2015), based on cross validation prediction error, model residual patterns, model parsimony, and biological considerations, found that the updated version of the Hoenig (1983) M estimator performed better than other commonly used estimators.…”

Markedly Similar Growth and Longevity of Green Jobfish Aprion virescens over an Expansive Geographic Range between the Hawaiian Archipelago and the Eastern Indian Ocean

The Green Jobfish Aprion virescens supports important commercial, recreational, and subsistence fisheries throughout its Indo-Pacific range. Concerns with previous estimates of age and growth from fish in Hawaii, along with evidence of variability in these parameters from locations outside the Pacific Ocean, limits their reliability as input parameters for assessments of this species, particularly in Hawaii. Previously validated aging criterion were applied to fish collected from within the Hawaiian Archipelago (main Hawaiian Islands and Northwestern Hawaiian Islands) and the eastern Indian Ocean to provide length-at-age, growth, and longevity information for stock assessment and management purposes as well as to further examine spatial variability across its range. The Bayesian information criterion was used as a measure of goodness of fit for von Bertalanffy models with different covariates to explore the influence of sex and location on growth. No divergence in growth trajectories was identified between sexes, and growth parameter estimates were not different within the Hawaiian Archipelago or between Hawaii and the eastern Indian Ocean. Empirical natural mortality estimates revealed that mortality was also very similar between sexes and among locations due to the similarity in maximum ages and growth parameter estimates. Considering there was dissimilarity in age and growth parameters between the current study and those published for this species from the Coral Sea and the western and central Indian Ocean, further investigation of potential clines in relation to latitude, and subsequently water temperature, need to be determined.

“…The lack of age-based biological studies for tropical deepwater fishes has limited the ability to develop effective fisheries assessment models and appropriate management and harvest strategies (Newman et al, , 2017a. Here, we have provided the first estimates of age-specific demographic parameters for E. carbunculus since the species was discovered to comprise two cryptic species (E. carbunculus and E.…”

“…as the principal target species. The status of most deepwater snapper stocks in the Indo-Pacific region is unknown due to insufficient biological and fisheries data (Newman et al, 2017a). Some exceptions include the deepwater snapper fishery for E. coruscans in Tonga, which is considered overfished (Hill et al, 2015), and the fisheries for Pristipomoides multidens in Western Australia (Newman et al, 2017b) and the Northern Territory of Australia (Grubert et al, 2013), which are considered to be fully exploited.…”

Oceanic, Latitudinal, and Sex-Specific Variation in Demography of a Tropical Deepwater Snapper across the Indo-Pacific Region

Deepwater tropical fisheries provide an important source of income and protein to Pacific and Indian Ocean coastal communities who are highly dependent on fish for food security. The development of quantitative assessments and management strategies for these deepwater fisheries has been hindered by insufficient biological and fisheries data. We examine the age-specific demography of the pygmy ruby snapper Etelis carbunculus, an important target species in tropical deepwater fisheries, across 90 • of longitude and 20 • of latitude in the Pacific and Indian Oceans. Our results show that growth of E. carbunculus varies significantly between oceans and sexes and across latitudes in both oceans. Estimates of natural and fishing mortality were similar between oceans, but higher for females than males in both oceans. Evidence of greater fishing pressure on females than males is likely due to the larger size-at-age of females compared to males, assuming that selectivity of the fishing gear is related directly to fish size. Sex ratios were significantly female biased in both oceans despite this species being gonochoristic, and maturity schedules were similar between sexes in the Pacific Ocean. This species exhibits a protracted spawning season from mid-spring to autumn (i.e., October to May) in the Pacific Ocean. These results represent the first estimates of age-specific demographic parameters for E. carbunculus, and provide the foundation for the development of the first species-specific assessment models and harvest strategies for the species. Future stock assessment models for E. carbunculus should consider sex-specific demographic parameters and spatial variation in demography. Our results reveal substantial differences in biology between E. carbunculus and the giant ruby snapper E. sp., a cryptic congeneric species, and thus contribute to greater clarity in managing fisheries that are dependent on these two species. Furthermore, the improved information on the life history of E. carbunculus contributes to the broader sustainable management and improved food security for deepwater snapper fisheries in the Indo-Pacific region.
