“…The reduction in aerobic scope is caused by reduced capacity of circulatory and ventilatory systems to meet oxygen demand. The reduced aerobic performance may enhance sensitivity to other stressors, including the availability of prey and predators, and result in reduced survival (Pörtner and Knust ; Neuheimer et al ; Arula et al , ).…”

“…In the Gulf of Riga (Baltic Sea), the abundance of herring larvae measuring between 17.1 and 20 mm (overlapping our flexion and postflexion life‐history stages) were most abundant at average sea surface temperatures varying between 15°C and 19°C. Peak abundances occurred at about 16.5°C and declined thereafter (Arula et al , ). A similar relationship was observed in the present study for flexion larvae.…”

The analysis of the abundance and distribution of the early life‐history stages of the western Baltic spring‐spawning herring population, spanning 23 yr, revealed that the abundance of yolk‐sac larvae was strongly spatially structured and significantly more abundant during the optimal temperature window for viable hatch of herring larvae (9°C to 13°C). The percentage of time encompassing this optimal temperature window exhibited a major contraction between 1995 and 2000 that may have contributed to reducing the supply of yolk‐sac larvae and ultimately contributed to reducing recruitment observed after 2000. Temperature also significantly influenced the abundance of preflexion and flexion larvae, defining dome‐shaped responses with maximum abundances observed between 10.27°C and 13.43°C and between 13.68°C and 18.53°C, respectively. The abundances of postflexion stage larvae were greatest at temperatures exceeding 14°C with no apparent decline in abundance at temperatures of up to 20°C. Temperature also played a significant role in influencing the abundance of larvae through its interaction with the abundance of the preceding developmental stage and provided evidence of stage‐specific temperature‐related mortality. There was also evidence of reduced survival during the preflexion–flexion transition in cohorts produced early in the season relative to those cohorts produced later. Although phenologically plastic species such as herring may be able to alter the dates of spawning, thus partially mitigating the effects of increasing rates of spring warming, constriction of the temperature windows for successful hatching and subsequent ontogenetic development may not be so easily mitigated by changes in phenology.

“…A Juday net (mouth opening of 0.1 m 2 , mesh size of 90 µm) was used to sample the whole water column vertically by pulling the net once from the seabed to the surface (see also [25][26][27]). The samples were immediately preserved in a 4% formaldehyde/seawater solution.…”

“…The abundance of copepod nauplii-the first prey of larval smelt-increased substantially since 1982, improving the feeding conditions for smelt larvae [26]. The feeding condition hypothesis is further supported by the fact that the abundance of herring larvae-main potential food competitor of smelt larvaesignificantly decreased in the 1990s [19,[25][26][27]]. Since we found K to be significantly higher in 2012, compared to the former period, we assume that improved feeding conditions during the early stages of life had a notable effect on the early maturation of smelt.…”

Maturation at a young age and small size of European smelt (Osmerus eperlanus): A consequence of population overexploitation or climate change?

Age of fish at maturation depends on the species and environmental factors but, in general, investment in growth is prioritized until the first sexual maturity, after which a considerable and increasing proportion of resources are used for reproduction. The present study summarizes for the first the key elements of the maturation of European smelt (Osmerus eperlanus) young of the year (YoY) in the North-eastern Gulf of Riga (the Baltic Sea). Prior to the changes in climatic conditions and collapse of smelt fishery in the 1990s in the Gulf of Riga, smelt attained sexual maturity at the age of 3-4 years. We found a substantial share (22%) of YoY smelt with maturing gonads after the collapse of the smelt fisheries. Maturing individuals had a significantly higher weight, length and condition factor than immature YOY, indicating the importance of individual growth rates in the maturation process. The proportion of maturing YoY individuals increased with fish size. We discuss the factors behind prioritizing reproduction overgrowth in early life and its implications for the smelt population dynamics.

“…Seasonal spawning components exhibit different growth rates, abundance trends (Harma, Brophy, Minto, & Clarke, 2012;, and morphologies (Messieh, 1975), and are managed separately in the Gulf of St. Lawrence (GSL) (DFO, 2016a). The reasons for such shifts are largely unknown but may be aggravated by changing temperatures (Arula, Raid, Simm, & Ojaveer, 2016;Melvin et al, 2009) or seasonally shifting fishing pressure (Jardine & Sanchirico, 2015).

Atlantic herring (Clupea harengus), a vital ecosystem component and target of the largest Northwest Atlantic pelagic fishery, undergo seasonal spawning migrations that result in elusive sympatric population structure. Herring spawn mostly in fall or spring, and genomic differentiation was recently detected between these groups. Here we used a subset of this differentiation, 66 single nucleotide polymorphisms (SNPs) to analyze the temporal dynamics of this local adaptation and the applicability of SNP subsets in stock assessment. We showed remarkable temporal stability of genomic differentiation corresponding to spawning season, between samples taken a decade apart (2005 N = 90 vs. 2014 N = 71) in the Gulf of St. Lawrence, and new evidence of limited interbreeding between spawning components. We also examined an understudied and overexploited herring population in Bras d'Or lake (N = 97); using highly reduced SNP panels (N SNPs > 6), we verified little‐known sympatric spawning populations within this unique inland sea. These results describe consistent local adaptation, arising from asynchronous reproduction in a migratory and dynamic marine species. Our research demonstrates the efficiency and precision of SNP‐based assessments of sympatric subpopulations; and indeed, this temporally stable local adaptation underlines the importance of such fine‐scale management practices.
