“…An unexpected but interesting finding was the high occurrence of insects in the pikeperch diet in Lake Höytiäinen but, unfortunately, we do not have samples of these macroinvertebrates for SIA. Insectivory is rare but not exceptional in adult pikeperch (Argillier, Barral, & Irz, ; Craig, ; Yagci et al, ). Intense insectivory has been connected to shortage of suitable‐sized prey fish and subsequent low growth rate of pikeperch (Vinni, Lappalainen, Malinen, & Lehtonen, ).…”

“…Smelt has been observed to be an important prey in winter diet of pikeperch in Lake Höytiäinen (H. Huuskonen, unpublished), but summer diet has not been studied previously. In general, insects and other invertebrates may contribute significantly to the pikeperch diet especially during declines of prey fish populations (Campbell, 1992;Yagci, Alp, Yagci, & Uysal, 2014).…”

Through the recent increases in abundance, pikeperch (Sander lucioperca) has not only become a valuable target for recreational and commercial fishing, but also the most important top predator in many lakes. Generally oligotrophic Lake Höytiäinen (283 km2) sustains one of the most economically valuable pikeperch stocks in Finland, and its annual fisheries yield (up to 5.5 kg/ha) is exceptionally high among Finnish lakes. Here, we followed seasonal movements of fish using conventional tagging, and studied short‐term and long‐term diet of pikeperch by stomach content and stable isotope analyses to examine if the movements were motivated by prey availability. A clear seasonal migration pattern was observed: in summer, 80% of the tag recoveries were obtained from the shallow and mesotrophic northern and western areas, whereas in autumn and winter, the deep and oligotrophic southern area dominated in the recaptures. The diet of pikeperch consisted of the most abundant fish species in the lake, perch (Perca fluviatilis) and roach (Rutilus rutilus), as well as insects. Stable isotope analysis indicated a shift from a dominance of pelagic food sources to littoral food sources during the growing season of pikeperch. Our results suggest that the pikeperch migrations facilitate efficient material transfer from the mesotrophic part while the deeper and oligotrophic part offers a favourable overwintering environment.

“…In Turkey, A. boyeri were commercially important (Saç et al, 2015) and they were considered invasive species in Turkish waters (Tarkan et al, 2015). A. boyeri has been found as prey of the largemouth bass, Micropterus salmoides and the northern pike, Esox lucius (Lorenzoni et al, 2002), the twaite shad, Alosa fallax (Ceyhan et al, 2012), the pike -perch, Sander lucioperca (Yağcı et al, 2014), and the european perch, Perca fluviatilis (Saç et al, 2015) in marine and freshwaters. In general, prey fish otoliths are undigested and they remain in predators' stomachs and intestines.…”

This study focuses on the relationships between otolith measurements and total length; otolith shape indices and the total length; among otolith measurements for three Atherina boyeri populations (Lake Eğirdir, Lake İznik, and Hirfanlı Dam Lake) to determine regional variations of these populations in Turkey. 356 specimens with 41.0-103.6 mm total length of three A. boyeri populations were examined and their otoliths were extracted and measured. Otolith width is the strongest indicator for the three A. boyeri populations although the otolith length, width, and weight are good indicators for the fish length in the different populations. The linear relationship was determined between A. boyeri total length and sagittal otolith sizes in the three populations. However, the best model for the relationships among otolith sizes can be change depends on populations differentiation. Exponential model is the best model for Lake Eğirdir population while the linear model is the best model for Lake İznik and Hirfanlı Dam Lake populations.

“…The study of fish diet in the wild can explain, on the one hand, growth variations, trophic migrations, and behaviors feeding. A lot of authors around the world have discussed the feeding of Sander in its various aspects [5][6][7][8][9]. In Morocco, despite of the ecological and socio-economic interest of this fish, studies dealing with its diet, its reproduction and other biological and ecological characteristics are absent in Morocco, which makes the fish development of this species difficult.…”

Food preferences of Pike Perch, Sander lucioperca (Linnaeus, 1758) in Morocco

Sander lucioperca hasbeen introduced in Morocco since 1939. This noble fish has shown a good ability to acclimatize to Moroccan conditions and has developed well [1]. The present study examines diet composition and predator-prey relationships that are dependent on size and weight between sander and its preys during the period October 2018-April 2019. Stomach contents of 287 specimens, whose size varies between 17 and 72 cm, from Al-Massira dam, wereanalyzed. The results showed that Sander feeding is composed of six categories of prey, the most important species was the Blue gill (Perch) with an occurrence index equal to 14.9%, the occurrence indices for other preys were respectively : Pike perch (8.01%), Tilapia (5.57%), Roach (0.69%), Black bass (0.69%) and Common carp (0.69%). It has been found that the total length of the preys increases with that of the Pike perch. Thus, the Pike perch is able to ingest preys of big weight and size. We also revealed that cannibalism was high, indicating a lack of forage fish in this lake.
