“…This trend has been observed in A. vulpes where it is exploited by subsistence fisheries (Rennert et al ., ) and the oldest A. glossodonta we found in our sample was 10 years with 88% of these being <7 years old. In comparison, the maximum observed age of A. glossodonta in Hawaii in 2015 was 15 years, with results from a smaller sample size in a location with an active recreational and small‐scale commercial fishery (Donovan et al ., ; Kamikawa et al ., ). With this in mind, the Hawaii state record for A. glossodonta was captured in, 1954 and still stands today at 18 lbs., 2 oz.…”

“…Despite the considerable efforts to understand and protect bonefishes in the Atlantic Ocean, congeneric species in less developed regions of the world have received little attention (Adams et al ., ). The life history of roundjaw bonefish Albula glossodonta (Forsskål 1775) in the Pacific Ocean has only been studied in Hawaii and Palmyra Atoll a nearly pristine marine reserve in the central Pacific Ocean (Donovan et al ., ; Friedlander et al ., ; Kamikawa et al ., ). Nevertheless, the species remains a foundation of many artisanal fisheries, particularly in sparsely populated Pacific islands and atolls with small communities that target and harvest albulids from spawning aggregations (Allen, ; Friedlander et al ., ; Johannes & Yeeting, ).…”

Bonefishes Albula spp. are important components of subsistence fisheries and lucrative sport fishing industries throughout their circumtropical distribution. In Oceania, however, Albula spp. have historically been overexploited and there is a growing need to balance the demands of competing fishing sectors, making the description of their life history a regional priority. To this aim, we collected biological samples from Albula spp. of Anaa atoll, French Polynesia, to identify the species that compose the stock and estimate their life‐history parameters including age, growth, reproduction and natural mortality. Our results indicate that Albula glossodonta is the species of bonefish present, with a maximum age that is below the, 20 year longevity of the genus (8 years in males and 10 years in females). Differential growth patterns existed between the two sexes (L∞ = 58, 78 cm fork length (LF) and K = 0.38, 0.21 for males and females, respectively). Males attained sexual maturity at 43 cm LF (c. 3 years) whereas females matured at 48 cm LF (c. 4 years) and oocyte production was significantly related to body mass, with a maximum batch fecundity of 1,133,767 oocytes in a 4406 g (70 cm LF) female. The gonado‐somatic index of harvested fishes indicated that the spawning season extends from March through September. Based on the observation of a, 20 year bonefish at the proximate Tetiaroa Atoll and several empirical models, estimates of natural mortality ranged from 0.21 to 0.68; however, an estimate of 0.21 was deemed most appropriate. This information facilitated the resurgence of a Rahui (temporary fishing closure) and community‐based management to protect A. glossodonta during a critical portion of their spawning season and in this context our results provide an important demographic baseline in evaluating the recovery of this fishery.

“…recapture) effort is primarily conducted on shallow sand flats where bonefish are customarily targeted with fly‐fishing equipment. In that context, strong site fidelity was reported after times at large in excess of 1,000 days between recapture, suggesting that bonefish return to their flats after seasonal spawning events (Boucek et al, ; Kamikawa et al, ; Larkin et al, ). Yet, the open nature of these environments has made the spatial and temporal characteristics of spawning movements difficult to document with conventional mark–recapture.…”

“…Previous scientific studies indicate that Albulids exhibit site fidelity to shallow‐water foraging habitats and their movements into these environments are controlled by fluctuations in tide, water temperature and the presence of predators (Cooke & Philipp, ; Danylchuk et al, ; Humston, Ault, Larkin, & Luo, ; Kamikawa et al, ; Larkin et al, ; Murchie et al, ). Less is known about the long‐term movements of this genus, but several studies have demonstrated that the home range of bonefish is surpassed to undertake seasonal spawning movements to offshore waters with access to the pelagic environment (Adams et al, ; Boucek et al, ; Danylchuk et al, ; Danylchuk, Lewis, Jud, Shenker, & Adams, ; Perez, Schmitter‐Soto, Adams, & Heyman, ).…”

Fisheries management requires knowledge on the population dynamics of exploited stocks. To that end, the present study used a mark–recapture approach to characterise the population demographics of roundjaw bonefish Albula glossodonta (Forsskål) and their interaction with a data‐limited fishery on Anaa Atoll in the Tuamotu Archipelago of French Polynesia. Over the course of the study, 2,509 bonefish were tagged and 12.3% were recaptured. The L∞ of bonefish was estimated at 71 cm fork length (FL) with a K of 0.17, based on changes in FL between capture events. Artisanal fish traps located in the migratory corridors of the atoll accounted for 94% of recaptures and these movements occurred during the waning moon. Fishing mortality increased as bonefish reach sexual maturity, recruiting to the trap fishery at age 4 with the onset of spawning behaviour. Bonefish abundance between ages 3 and 5 was estimated to be 29,079 individuals. This case study demonstrated the utility of mark–recapture in filling knowledge gaps that impede the management of data‐limited fisheries. Ultimately, these results supported the creation of an Educational Managed Marine Area and the resurgence of rahui (seasonal closure) to manage this fishery.

“…An important component of angler buy-in to conservation is their participation in data acquisition, especially for bonefish, tarpon, and permit for which data are scarce (Adams et al 2013). For example, angler-generated data are essential for fisheries management in Hawaii (Kamikawa et al 2015), and spatial data on fishing effort has been an essential part of the data gathering effort for a revised spatial management strategy in the Florida Keys National Marine Sanctuary (Black et al 2015). Angler-scientist collaborations are not without difficulties, however, as was revealed in a recent study that expended considerable effort with limited results using angler-based mark-recapture to track movements of permit (Ahrens et al 2015).…”

The fish of the sub-tropical and tropical flats including bonefish (Albula spp.), Atlantic tarpon (Megalops atlanticus), and permit (Trachinotus falcatus), capture the imagination of specialized coastal marine recreational anglers. Until recently, little was known about the biology and natural history of these iconic species. Flats ecosystems are under threat from coastal development and environmental change while basic information on demographics and population size is lacking. This makes it difficult to understand the consequences of these threats, or to formulate potential management strategies. Through extensive partnerships involving anglers, industry, conservation organizations, natural resource agencies, and academics, the mysteries surrounding these species are starting to be solved. Nonetheless, many challenges remain. The systematics of these fish is complex, particularly for the bonefish which include a number of cryptic species. Identifying the timing and habitats associated with reproduction remain high priority such that management efforts can target protecting that important life-history event. Information on the spatial ecology of flats fish at various spatial scales is being elucidated by electronic tagging studies and angler tagging programs. Habitat science for these fish continues to improve but there is still need to identify effective habitat restoration strategies. Catch-and-release science has improved dramatically (especially for A. vulpes in The Bahamas) although there is need to for additional work across regions and species. Targeted species-specific management strategies (e.g., catch-and-release regulations) as well as more ecosystem-level strategies (e.g., habitat protection and fishing effort management) are increasingly being used for active management of flats fish and their habitats. Partnerships will remain key to addressing outstanding research questions and in working cooperatively to ensure that evidence (both scientific and stakeholder knowledge) forms the basis for management decisions. ContextCoastal marine waters in tropical and sub-tropical regions are often characterized by expansive shallow areas with adjacent tidal creeks collectively referred to as Bflats^. The flats are a complex habitat mosaic comprised of mangroves, sea grass, benthic algae, sand, coral rubble, limestone, and mud bottom that supports an inherently diverse community that includes resident species and species that use these habitats as nurseries (Barbier Environ Biol Fish (2015) 98:2123-2131
