“…It is well known that predator−prey interactions are affected by the relative size of the predator and prey, but the size dependence may be less prominent in small pelagic fish. It has been found that mean food size (van der Lingen et al 2009) or wet mass and prey composition (Plounevez & Champalbert 2000, Schaber et al 2010 do not relate to the size of adult anchovy, nor was any relationship found between an cho vy length and maximum prey size: larvae, juveniles and adults fed on the same plankton size classes (Borme et al 2009). Therefore, we do not expect the higher diversity observed in the anchovy diet to result from the size distribution of fish in our sample.…”

“…Sprat feed mainly on copepods and less on larger planktonic prey (Ellis & Nash 1997, Tič ina et al 2000, Casini et al 2004, Möllmann et al 2004 and have a very similar diet to North Sea herring (Silva 1973). Anchovy in the North Sea consume mainly copepods and malacostracans, with other items like fish, chaetognaths, larvaceans, gastropods and cephalopods also being found (Raab et al 2011), and the species also has a varied diet in the western Baltic Sea (Schaber et al 2010). Clupeids can eat both fish larvae and eggs (e.g.…”

“…European anchovy is a confirmed zooplanktivore in both the North and Baltic Seas (Schaber et al 2010, Raab et al 2011, just like in other parts of its distribution, e.g. the Bay of Biscay (Plounevez & Champalbert 1999), the Mediterranean (Tudela & Palomera 1995 and in the Benguela system (van der Lingen et al 2006).…”

European anchovy Engraulis encrasicolus increased its abundance and distribution in the North Sea during the mid-1990s and may consume similar zooplankton to and/or compete with other occupants of the North Sea like herring Clupea harengus and sprat Sprattus sprattus. The diets of adult anchovy, sprat and juvenile herring of comparable sizes, sampled close in time and space, were compared to understand how the 3 species prey on zooplankton and establish whether their diets overlap or not. Anchovy was found to be more generalist, consuming a higher diversity of prey items. Herring was more specialized, with low diversity of food items. Sprat was intermediate between anchovy and herring. The dietary overlap between anchovy and sprat was highest, followed by herring and sprat before anchovy and herring. The mean weight of stomach contents did not differ between species. We conclude that of the 3 species, anchovy is likely to be the least affected by changing plankton communities.

“…Consumption of Oncaea by small anchovies is in accord with where juveniles sampled in the Gulf of Lions during summer 2007 fed on some Oncaea, even if the dominant prey groups in their study were cladocerans and copepods such as Clauso/Paracalanidae and C. typicus. It is the first time that a high contribution of diatoms in the diet of large anchovies was observed in the Gulf of Lions but this has been observed in the Baltic Sea (Schaber et al, 2010). Nevertheless, high diatom consumption has been observed in only one sampling station in 2012 and thus cannot be considered as a general phenomenon.…”

This study was funded by the programmes PERSEUS FP7 EU project, EMIBIOS FRB, IPP WP2-MERMEX and EcoPelGol FFP.Increasing abundance of non-commercial sprats and decreasing biomass and landings of commercial anchovies and sardines justify the need to study the feeding ecology and trophic niche overlap of these planktivorous species in the Gulf of Lions. Their diet has been investigated on the basis of stomach content and stable isotope analyses in 2011 and 2012 according to different depths and regions in the study area. The main prey were Corycaeidae copepods, Clauso/Paracalanus, Euterpina acutifrons and Microsetella, for sprats and small copepods, such as Microsetella, Oncaea and Corycaeidae, for anchovies and sardines. This is the first time that the diet of sprats is described in the Gulf of Lions. Sprats fed on a larger size spectrum of prey and seem to be more generalist feeders compared to anchovies and sardines. Ontogenetic changes as well as spatial and temporal variations of the diet occurred in the three species. Stable isotope analysis revealed mobility of sardines and sprats among feeding areas while anchovies exhibited preferred feeding areas. Sprats showed a higher relative condition assessed by C/N ratios than sardines and anchovies. Our results showed an overlap of the trophic niches for the three species, indicating a potential trophic competition in the Gulf of Lions. (C) 2015 Elsevier B.V. All rights reserved

This study examines the feeding habits of anchovy (Engraulis encrasicolus), sardine (Sardina pilchardus) and round sardinella (Sardinella aurita). The results are combined with previously published information on feeding-related morphological features (i.e. mouth area, intestine length and tail area) in order to explore morphological affinities between species and the effect of ecomorphology on their co-existence. These species were mainly zooplanktivorous and no dietary differences were found with sex and season. Anchovy preyed mainly on Crustacea larvae, whereas sardine and round sardinella on Copepoda. In the majority of cases (>90%), the individual fractional trophic level of all species ranged between 3.0 and 3.5, classifying them as omnivores with preference to animals. The feeding-related morphological features differed between anchovy and the two other species, whereas only intestine length differed between sardine and round sardinella. The fact that the diet and morphology of round sardinella show a greater resemblance to those of sardine further supports the hypothesis that round sardinella is a particulate feeder, as is sardine. Hence the three species tend to exploit the same food resources differently throughout the year. Thus, they make best use of the environment and its resources, in order to avoid competition and achieve optimum feeding conditions throughout their life cycles.

Diet composition and feeding of European anchovy Engraulis encrasicolus in Kiel Bight, western Baltic Sea

Abstract: Diet composition of the expanding southern species European anchovy Engraulis encrasicolus in the western Baltic Sea was investigated. Results revealed an interesting case of bentho-pelagic coupling with potential implications for local fish species through competition for food resources.
