“…The relationship between the spatial distribution of small pelagic fish stocks and environmental factors (e.g. temperature) have been reported in marine ecosystems globally (Peck et al 2021), such as in the Patagonian stock of Argentinian anchovy, E. anchoita (Hansen et al 2001). In accordance with our findings, greater crested terns in South Australia, which mainly prey on clupeid fishes during chick provisioning stages, typically foraged over warmer waters (18-21 °C) that are shallow and are associated with high levels of chlorophyll a (McLeay et al 2010).…”

“…Local prey distribution and abundance can be strongly affected by variables at seasonal timescales, including phenological changes in sea surface temperature (SST). Seasonal changes in SSTs affect the spatial distribution and abundance of small pelagic fishes, which are an important food source for many seabird species (Hansen et al 2001;Peck et al 2021). In Norway, for example, sea temperature controls plankton production, which in turn influences the abundance of the Atlantic puffin's (Fratercula arctica) main prey, first-year herring, mediating fledgling success in this population (Durant et al 2003).…”

Monitoring seabird diet can provide insights into marine ecosystems that are logistically difficult or costly to observe with traditional fisheries survey methods. Using digital photography, we described the diet of greater crested terns (Thalasseus bergii) breeding on Montague Island (36°15′ S, 150°13′ E), a colony located in an oceanographically dynamic region of southeast Australia. We investigated how the type and size of prey brought back to the colony changed in relation to both breeding stage and variation in local environmental conditions. 2469 prey items were identified to species or family level over 35 consecutive days of photo-sampling in 2018. Australian anchovy (Engraulis australis), a surface-schooling clupeid fish, was the most abundant prey returned to the colony during all breeding stages (84.5%). The proportion of anchovy increased from 77.0% when birds were provisioning their adult partners during incubation, to 92.4% when they were provisioning chicks, suggesting selective foraging behaviour on this energy-rich species to facilitate rapid chick growth. Anchovy size was significantly larger during incubation (91.1 ± 14.9 mm), smaller during early chick provisioning (71.8 ± 11.0 mm), and increased slightly during mid provisioning (79.6 ± 11.9 mm), indicating adaptive prey selection that is matched to the physical requirements of different breeding stages. The proportion of anchovy prey was also influenced by sea surface temperature (SST), with anchovy becoming more dominant with increasing local SSTs, up to ~ 17.5 °C. This study gives new insight into the types of prey that are seasonally available to predators in this region. The strong specialisation by greater crested terns for one energy-rich species of schooling fish (anchovy) suggests that variation in the size and composition of their prey may serve as an indicator of change in the pelagic ecosystem off southeast Australia.

“…In eastern boundary current upwelling regions, such as the California Current System (CCS), sardines and other small pelagic fish play a key role in the transfer of energy between planktonic organisms and higher trophic levels species, such as seabirds and marine mammals (Cury et al, 2000;Peck et al, 2021). Healthy sardine populations also account for a substantial fraction of the global fish catch (Fréon et al, 2005) and support important commercial fishing activities worldwide, yielding multimillion dollars ex-vessel revenues (i.e., revenues from landed catch) off the west coast of the United States alone (Pacific Fishery Management Council (PFMC), 2011).…”

Projected Shifts in 21st Century Sardine Distribution and Catch in the California Current

et al. 2021

Predicting changes in the abundance and distribution of small pelagic fish species in response to anthropogenic climate forcing is of paramount importance due to the ecological and socioeconomic importance of these species, especially in eastern boundary current upwelling regions. Coastal upwelling systems are notorious for the wide range of spatial (from local to basin) and temporal (from days to decades) scales influencing their physical and biogeochemical environments and, thus, forage fish habitat. Bridging those scales can be achieved by using high-resolution regional models that integrate global climate forcing downscaled from coarser resolution earth system models. Here, “end-to-end” projections for 21st century sardine population dynamics and catch in the California Current system (CCS) are generated by coupling three dynamically downscaled earth system model solutions to an individual-based fish model and an agent-based fishing fleet model. Simulated sardine population biomass during 2000–2100 exhibits primarily low-frequency (decadal) variability, and a progressive poleward shift driven by thermal habitat preference. The magnitude of poleward displacement varies noticeably under lower and higher warming conditions (500 and 800 km, respectively). Following the redistribution of the sardine population, catch is projected to increase by 50–70% in the northern CCS and decrease by 30–70% in the southern and central CCS. However, the late-century increase in sardine abundance (and hence, catch) in the northern CCS exhibits a large ensemble spread and is not statistically identical across the three downscaled projections. Overall, the results illustrate the benefit of using dynamical downscaling from multiple earth system models as input to high-resolution regional end-to-end (“physics to fish”) models for projecting population responses of higher trophic organisms to global climate change.

“…The variability of climate is a major factor contributing to the fluctuation of fish populations and stocks affecting especially the recruitment of small-sized pelagic fish like anchovies, sardines and herring (Lehodey et al, 2006;Peck et al, 2021). In these species, environmental factors modify the reproductive success when the eggs and sperm are released into the water, but they act also through the parent population by affecting the females' capacities to produce viable offspring.…”

Long-Term Data Reveal the Associations of the Egg Quality With Abiotic Factors and Female Traits in the Baltic Herring Under Variable Environmental Conditions

et al. 2021

In fish, the lipid resources of the female form a link between the environment and progeny, contributing to the contents of the egg yolk. Variation of the environmental conditions is therefore expected to affect the egg quality via maternal pathways, reflecting the female’s response to the environmental factors before spawning. We investigated the content of lipids and thyroid hormones in the ovary and eggs of the Baltic herring during 1988–2019, when salinity of the Baltic Sea first declined and then stabilized to a lower level, and winters varied between severe and mild. The total lipid resources of spawning females decreased by 40–50% during the study, and the ovarian lipid concentration followed this trend resulting in a decrease of the lipid content of eggs. The concentration of thyroid hormones in the ovary suggested a hormonal response in females to salinity and winter temperature and was observable also in the content of thyroid hormones in the eggs. A change in the egg lipid content took place approximately around 1998 (SE ± 3 years) suggesting that in declining salinity, egg quality was associated with salinity and intrinsic factors in the female, i.e., fecundity and amount of lipids deposited into the ovary. However, during the period of stable salinity, egg quality was mainly limited by the female’s lipid resources. As also the body size of the females decreased over the years, it is suggested that small body size can be a key phenotypic trait to reduce the environmental impact on egg quality in variable environmental conditions.
