“…The simple (reduced) model of lipofuscin accumulation rate was applied to estimate ages for shrimp collected from field surveys in Yaquina Bay and Willapa Bay because it provided a more precise method of estimating age than gastric mill lamellae count (lower error estimates and few significant tank effects, Tables 2 & 3). Lipofuscin-based age structure of shrimp collected from the OSU dock site showed a significant portion of the shrimp taken there were aged 2–4 (Figure S2), which agrees with our assumption that this site was colonized following a period of steady recruitment beginning in 2010 (Dumbauld & Bosley, 2018).…”

“…When this rate was applied to estimate population age structure at the OSU dock location in Yaquina Bay, Oregon, results showed the site was dominated by young shrimp, with most of the shrimp sampled from that location <4 years old (Figure S2). This age structure is consistent with measurements of post-larval settlement at this location since 2010 (Dumbauld & Bosley, 2018). Prior to 2010, shrimp were fewer at this site, which has since been subject to regular strong recruitment events.…”

“…Shrimp from Yaquina Bay included 109 Neotrypaea californiensis specimens collected using a clam gun (a coring tool commonly used to harvest clams from soft intertidal sediments) from the south side of the estuary in summer 2014 (OSU Dock, Figure 1). Annual recruitment had been observed at this location beginning in 2010 and shrimp here were presumably ≤4 years old (Dumbauld & Bosley, 2018). Twenty shrimp sampled as part of a 2013 demographic survey in Yaquina Bay on Idaho Flats were also included in the study.…”

The burrowing shrimp Neotrypaea californiensis is an important ecosystem engineer that inhabits estuaries along the US Pacific Northwest coast. This species plays an important role in the estuarine ecosystem but negatively impacts oyster aquaculture through its burrowing activities. Development of population models for burrowing shrimp management requires more detailed life history information and accurate estimates of age. Ageing studies have been limited for crustaceans because it is generally believed that they do not retain structures with annual deposits commonly used to age other marine organisms, when they moult their exoskeletons. A mesocosm growth experiment and field surveys were combined to compare the performance of two ageing techniques, quantification of autofluorescent lipofuscin and gastric mill ossicular lamellae, for estimating age in N. californiensis. Animals of known age were grown in outdoor mesocosms and sampled regularly to correlate age metrics with body size and true age. Lipofuscin concentration increased with time across multiple cohorts at the rate of 1.430 ± 0.060 ng µg−1 year−1. Lamellae counts also increased with time (4.922 ± 0.337 lamellae year−1). While age estimates based on lipofuscin concentration and lamellae counts generally agreed, carapace size did not correlate to either age metric. Lamellae counts from field collections suggest they are added sequentially with age but the relationship can vary by location. When used together, the application of both techniques may provide robust estimates of crustacean age especially when size-based measurements are imprecise.

“…low genetic diversity and nearly no inbreeding) suggested a large randomly mating population of T. australiensis along a 250‐km stretch of the East Coast of NSW that could be managed as a single population. Whereby conserving the population at one location will benefit the others through gene flow among locations (Dumbauld & Bosley, 2018; Fogarty & Botsford, 2006; Sanvicente‐Añorve et al., 2018). However, high catch rates could still cause over‐exploitation of the fishery (Chick, 2021; Rotherham, 2004), which would ultimately reduce population sizes across the geographic range through time (Thorpe et al., 2000).…”

From a conservation standpoint, species that are managed without consideration of their population sizes and connectivity have the potential to be over‐exploited and/or incur population decline. The burrowing shrimp, Trypaea australiensis, is an important ecosystem engineer and fishery resource caught in large numbers for which population information is unknown for properly managing the species. Here, we determined the level of population structure of T. australiensis across three locations along the East Coast of New South Wales, Australia, using genome‐wide single nucleotide polymorphisms (SNPs) obtained through double digest Restriction‐site Associated DNA‐sequencing (ddRAD‐seq). Analysis of population structure, including pairwise Fst (−0.003 to −0.001), STRUCTURE (K = 2) and Discriminant Analysis of Principal Components (DAPC) showed no evidence of structure among locations. Our findings provide crucial preliminary population genetic data for a key cryptic species, that also suggests gene flow among sampling locations enables the management of fisheries throughout the study area as a single unit.

“…Planktotrophic larvae of callianassids go through three to seven zoeal stages to reach the decapodid stage (Kornienko, Korn, & Golubinskaya, ; Kubo, Shimoda, & Tamaki, ; Pohle, Santana, Jansen, & Greenlaw, ). Following hatching, these shrimp larvae are exported to the coastal ocean, where they grow before returning to the shore (Bilodeau, Felder, & Neigel, ; Dumbauld & Bosley, ; Yannicelli et al, ). In coastal waters of mid‐western Kyushu, Japan, under a meso‐tidal and mixed, mainly semidiurnal, tidal regime (Fujimoto, ), local populations of the callianassid species, Nihonotrypaea harmandi (Bouvier, ), inhabit intertidal sandflats in a region from the outer one‐third part of an estuary (Ariake Sound) to the inner‐shelf coastal ocean (Amakusa‐nada) (Tamaki, Itoh, & Kubo, ; Figure ).…”

Semilunar postlarval settlement periodicity ensuing from semilunar larval release cycle in the Nihonotrypaea harmandi (Crustacea, Decapoda, Axiidea, Callianassidae) population on an intertidal sandflat in an open marine coastal embayment

Many decapod crustaceans in marine intertidal habitats release larvae toward coastal oceans, from which postlarvae (decapodids: settling‐stage larvae) return home. Decapodid settlement processes are poorly understood. Previous studies showed that in Kyushu, Japan, the callianassid shrimp population on an intertidal sandflat of an open bay joining the coastal ocean near a large estuary released eight batches of larvae basically in a semilunar cycle from June through October and that decapodids performed diel vertical migration, occurring in the water column nocturnally. We conducted (a) frequent sampling for population density and size‐composition on the sandflat through one reproductive season, (b) planktonic and benthic sampling for decapodids around the bay mouth, and (c) current meter deployment at three points across the bay mouth for tidal harmonic analysis. On the sandflat, six batches of newly‐settled decapodids (settlers) occurred in a semilunar periodicity until October, with peaks occurring 0–3 days before syzygy dates except for the first one. For larval Batches 1–4, buoyancy‐driven shoreward subsurface currents during July to mid‐October would transport some pre‐decapodid‐stage larvae (zoeae) toward the bay. The absence of expected settler Batches 7–8 would be due to the converse subsurface currents caused by water‐column mixing and seasonal winds after mid‐October, carrying zoeae offshore. Once in the bay, phasing of night and nighttime‐averaged shoreward tidal current explained the settlement pattern for Batches 1–4. For Batches 5–6 occurring in mid‐September to mid‐October, water currents generated by seasonal wind and tidal forcings may have caused peak settlement after the time expected from tidally‐driven decapodid transport.
