“…Time to hatch in the wild has been observed in a single study in the Gulf of Alaska at 67 days of total incubation (Robards, Piatt, et al, 1999). Laboratory studies revealed that development is highly temperature‐dependent for A. americanus and the European congener A. marinus , which can result in interannual and regional variability in hatch phenology for these species (Régnier, Gibb, & Wright, 2018; Smigielski et al, 1984). Yolk‐sac larvae begin to appear in ichthyoplankton tows in February in Nova Scotia and in December on Georges Bank, Nantucket Shoals, and Stellwagen Bank, though peak hatching is in January for these more southerly regions (Dalley & Winters, 1987; Potter & Lough, 1987; J. Llopiz, unpublished data).…”

“…The adult diet of Ammodytes in the NWA is poorly known, with most existing studies focusing on A. dubius (Danielsen et al, 2016; Meyer et al, 1979) and the last comprehensive foraging study within Northeast U.S. shelf waters conducted in the late 1970s (Bowman, 2000). Where diets have been characterized, large and energy‐rich copepods, primarily members of the genus Calanus, are prominent and thought to affect recruitment success and productivity (Bowman, 2000; Danielsen etal., 2016; van Deurs, van Hal, Tomczak, Jónasdóttir, & Dolmer, 2009; van Deurs, Jørgensen, & Fiksen, 2015; Lindegren et al, 2018; Régnier et al, 2018; Scott, 1973) . Of ecological significance, in areas where NWA Ammodytes are particularly abundant, such as Georges Bank, they can exhibit top‐down effects on zooplankton, consuming significant proportions of total annual production (Gilman, 1994).…”

“…In European waters, environmental variables (e.g., water velocity and bottom temperature) as well as top‐down and bottom‐up forcings have been associated with Ammodytes ( A. marinus , A. tobianus and Hyperoplus lanceolatus , Ammodytidae) distribution and abundance (Frederiksen, Edwards, Richardson, Halliday, & Wanless, 2006; van der Kooij, Scott, & Mackinson, 2008; Tien et al, 2017). Bottom‐up effects were postulated where significant correlations existed between A. marinus recruitment in the North Sea and the production of Calanus eggs (van Deurs et al, 2015; Régnier et al, 2018). Intraguild trophic relationships among forage fishes may also contribute to oscillations in relative abundances (Irigoien & de Roos, 2011).…”

The American sand lance (Ammodytes americanus, Ammodytidae) and the Northern sand lance (A. dubius, Ammodytidae) are small forage fishes that play an important functional role in the Northwest Atlantic Ocean (NWA). The NWA is a highly dynamic ecosystem currently facing increased risks from climate change, fishing and energy development. We need a better understanding of the biology, population dynamics | 523 STAUDINGER ET Al.

Timing of Sandeel Spawning and Hatching Off the East Coast of Scotland

et al. 2019

The lesser sandeel, Ammodytes marinus, is a key forage fish species in the North Sea. Mean lengths and abundances of sandeels have declined steeply since the 1990's and these are associated with declining breeding success of various seabird species on the east coast of Scotland, especially kittiwakes. The declining lengths have led to a mismatch between the peak in food demand arising from chick rearing, and the appearance of appropriately sized young sandeels in the foraging areas of the birds. A 10-year time series of sandeel larval samples between 2000 and 2009 offer a rare opportunity to analyze trends in spawning and hatch dates and determine whether they contributed to changes in mean lengths. By analyzing the abundance, length, and age distributions of sandeel larvae we were able to determine the temporal distribution of hatching rates each year, and back-track to the likely spawning dates of the sandeels. Estimated spawning dates showed no evidence of correlation with environmental cues such as tidal or lunar phases. However, hatch end dates varied by 20 days over the 10year period and were correlated with the date of the seasonal minimum of sea bottom temperature. We show a significant decline between growth rate and 0-group length between 2000 and 2009, and suggest that changes in food quality and availability, rather than shifts in hatch dates, are likely to be responsible for current declines in the availability of sandeels to seabirds.

BackgroundLesser sandeel (Ammodytes marinus) is widely distributed in North Sea ecosystems. Sandeel acts as a critical trophic link between zooplankton and top predators (fish, mammals, sea birds). Because they live buried in the sand, sandeel may be directly affected by the rapid expansion of anthropogenic activities linked to their habitat on the sea bottom (e.g., hydrocarbon extraction, offshore renewable energy, and subsea mining). It is, therefore, important to understand the impact of cumulative environmental and anthropogenic stressors on this species. A detailed description of the ontogenetic timeline and developmental staging for this species is lacking limiting the possibilities for comparative developmental studies assessing, e.g., the impact of various environmental stressors.ResultsA detailed description of the morphological development of lesser sandeel and their developmental trajectory, obtained through visual observations and microscopic techniques, is presented. Methods for gamete stripping and intensive culture of the early life stages are also provided.ConclusionThis work provides a basis for future research to understand the effect of cumulative environmental and anthropogenic stressors on development in the early life stages of lesser sandeel.
