“…Larger and older females produce a higher number of offspring that have a larger size and probably greater short‐term survival than the progeny of small females. Thus, the presence of large females could dampen generally strong fluctuations in recruitment especially in a species such as pikeperch that typically has Ricker‐type overcompensatory recruitment dynamics (Heikinheimo, Pekcan‐Hekim & Raitaniemi, ). However, there were substantial among‐population differences in the size‐dependent maternal influences.…”

Maternal characteristics typically affect the recruitment of an exploited fish population. The size and age at maturity, as well as the effects of maternal traits on relative fecundity and egg dry weight, were studied in six exploited pikeperch populations in Finnish lakes. The among‐lake variation in the maternal characteristics was substantial. The estimated total length at maturity (L10, L50, L90) varied between 318–444, 403–423 and 444–527 mm, respectively, largely depending on the average growth rate and body condition of pikeperch. The estimated L50 was generally close to the recently imposed national minimum size limit (42 cm). The estimated age at maturity (A50) ranged from 4.2 to 6.9 year. Both relative fecundity and egg dry weight significantly increased with female size and age, indicating size‐ and age‐dependent maternal effects on egg characteristics and quantity, and emphasising the importance of large individuals for reproduction. The observed among‐population differences in the size‐dependent maternal influences highlight the need for stock‐specific management of pikeperch fisheries. The conservation of large females should be promoted to increase recruitment and reduce its variability.

“…The mean water temperature in the Archipelago Sea during July-August has been favorable to pikeperch (Sander lucioperca) reproduction (Pekcan-Hekim et al, 2011) in several years during the first decade of the millennium (Heikinheimo et al, 2014). The eutrophication and turbidity levels have been fairly stable during the past decade (Anonymous, 2011a).…”

“…The optimal temperature for S. lucioperca growth is relatively high, In the second part, the largest 0+ S. lucioperca (outlier) was omitted from the regression. (Hokanson, 1977;Wang et al, 2009) and many previous studies reported a positive relationship between S. lucioperca cohort strength and temperature (Lehtonen et al, 1996;Kjellman et al, 2003;Heikinheimo et al, 2014). The spring temperature increase stimulates S. lucioperca to spawn and a higher temperature reduces the time to hatching Löffler et al, 2008).…”

Year to year fluctuations in 0+ fish cohort strength are a common phenomenon. Many factors can affect cohort strength during the fish's early life period. In this study, development of a 0þ pikeperch Sander lucioperca cohort in the pelagic zone was studied by trawling for 50 days from first larvae hatching, in two consecutive years. In 2007, an abundant S. lucioperca cohort collapsed suddenly soon after hatching. After the incident, slow-growing S. lucioperca prevailed in the catch. In 2008, the catch gradually increased during the whole study period because of prolonged hatching. Environmental factors differed mainly in a slower temperature increase, higher water level and higher zooplankton abundance in 2008 compared to 2007. Our study revealed that a strong 0þ S. lucioperca cohort at the time of hatching might not result in a strong S. lucioperca cohort in general.
