“…Both areas hold suitable habitats for herring to spawn. Herring may colonize artificial habitats for spawning, as seen in the Kiel Canal (Weber 1971, Paulsen et al 2014 or the Østerbøvatn (Aasen 1953). While the environmental conditions in the Kiel Canal are similar to the Baltic Sea and herring found inside the canal did not form an individual population, the herring in Østerbøvatn are classified as a single population, distinct from the neighbouring population in the full marine habitat.…”

Pelagic marine fish often display highly dynamic migration patterns. However, such movement behaviour is usually studied at the population or school level, while less is known about individual movement characteristics and habitat transitions. During March 2012 to June 2013, we used acoustic tags and moored receivers to monitor the behaviour of Atlantic herring Clupea harengus L. (N = 47) throughout a range of habitats on the Skagerrak coast in southern Norway. Five of the tagged herring entered a former lake transformed into an artificial estuary by a humanmade canal linking the former lake to the open ocean. Herring resided in this system for up to 36 d. All tagged herring left the fjord where they were tagged by early August 2012. This habitat transition was detected by the receivers as 3 main pulses of tagged individuals, which were assumed to be formed by putative populations mixing in the area. Most transitions occurred during nighttime regardless of tidal cycle, and it is suggested that spawning is the primary driver for entering the fjord and artificial estuary. Later detections at a separate receiver system 17 km to the northeast suggest that some herring may overwinter in coastal areas. In the spring of 2013, 3 of the tagged herring returned to their original fjord tagging location. Our study reveals new aspects of herring migration dynamics linked to anthropogenic modifications of connectivity, and suggests that capacity for individual behaviours in schooling fish may be underestimated.

“…In previous studies we observed first indications for food limited growth rates of larval herring in the Kiel Canal [53,54], an artificial waterway in northern Germany, with a limited data set. In this follow-up study we analyzed a 6-years-time series including RNA:DNA derived growth rates of 1177 larval herring and taxonomically differentiated prey field data in order to investigate potential reasons for this phenomenon and to test the hypothesis that food-limited growth of larval fish can occur recurrently in coastal habitats and at inter-annually varying prey levels.…”

“…To define and detect food-limitation, larval growth data from Kiel Canal were compared to larval growth data from another important habitat for western Baltic Sea spring spawning herring, the Greifswalder Bodden (Bodden is the German term for an enclosed, shallow and low saline bay at the Baltic Sea coast; Fig. 1; for further information on this site, please see [54]) with samples collected in the spring seasons 2010-2012. The sampling procedure was the same as in the Kiel Canal, apart from the fact that larvae were frozen in liquid nitrogen on board.…”

“…A detailed description of the analysis is given by Clemmesen [16,17]. Larvae caught in 2011 however, were defatted before analyzing RNA:DNA and analyzed according to Malzahn et al [48,49] to analyze the effects of essential fatty acids on larval growth rates [54]. Comparison with the classical approach by Clemmesen [16,17] showed no significant differences between RNA:DNA of defatted and non-defatted larvae.…”

Food-limited growth of larval fish, defined as growth rates lower than observed in other habitats or from laboratory experiments at a given temperature, is rarely reported in field studies. This would imply that either larval fishes are living in an environment characterized by plenty of food, that nutritional condition selective mortality (i.e., eliminating the weak) is very strong, or this impression is caused by misinterpretation of data concerning e.g., poor taxonomical resolution of potential prey items, i.e., total potential prey abundance is high, but positively selected food is actually scarce. We analyzed RNA:DNA derived growth rates of herring larvae (Clupea harengus L.) and taxonomically differentiated prey field data of six consecutive spring seasons from the Kiel Canal, an artificial waterway in northern Germany, in order to test if food-limited growth in larval fish can occur recurrently in coastal habitats. In all years analyzed, larval growth rates decreased simultaneously with prey abundance at the end of each larval season. Furthermore, larval growth rates were observed to be lower than mean growth rates observed in another herring larvae nursery area at temperatures above 15 °C. Asymptotic relationships between prey abundance and larval growth rates were observed, further supporting the hypothesis of food-limitation. As larval growth was best explained by the abundance of the numerically dominant calanoid copepod Eurytemora affinis, the paramount importance of the dominant prey item is highlighted. We conclude that food limitation can be a severe and re-occurring issue for larval fish in coastal habitats, and that certain prey items play a crucial role in determining larval growth rates, and therefore potentially recruitment.

Atlantic herring (Clupea harengus) migrates from offshore to coastal areas to spawn and their eggs and larvae may substantially increase prey resources for resident predators. We combined an in situ predator exclusion experiment using eggs naturally spawned on submerged aquatic vegetation and field observations of predator abundance to estimate the magnitude of predation mortality of herring eggs. During our predator exclusion experiment, performed in an important spawning ground in the southwest Baltic Sea, 20% of the herring eggs were consumed resulting in an extrapolated predation of 42% of all eggs between spawning and hatch. Abundance and stomach content analyses indicated that one predator (threespine stickleback, Gasterosteus aculeatus) was responsible for the majority of the predation impact. Predation mortality estimates from this in situ study were more than 10-fold higher than those of an empirical egg predation model for the same predator in the same region. Our findings highlight the potential of resident predators to regulate the survival of early life stages of ocean-going fishes that rely on the nursery functions of inshore transitional waters.
