Zooplankton prey selection among three dominant ichthyoplankton species in the northwest Gulf of St Lawrence
The diets and feeding niches of early-stage larval sandlance ( Ammodytes spp.), arctic shanny ( Stichaeus punctatus ), and snakeblenny ( Lumpenus lampreytaeformis ) were examined to study interactions among these dominant fish species and to better understand the ecological processes involved in str...

The diets and feeding niches of early-stage larval sandlance ( Ammodytes spp.), arctic shanny ( Stichaeus punctatus ), and snakeblenny ( Lumpenus lampreytaeformis ) were examined to study interactions among these dominant fish species and to better understand the ecological processes involved in structuring the ichthyoplankton community in the northwest Gulf of St Lawrence (GSL).

The feeding incidence of sandlance larvae was lower than expected when compared with other similar studies. Snakeblenny larvae were larger and more developed at sampling time; they occupied a different feeding niche with larger prey species compared with sandlance and arctic shanny larvae. In the northwest GSL, the presence of Calanus glacialis and Calanus hyperboreus may be favourable for arctic shanny and snakeblenny since these copepod species are less exploited by sandlance larvae.
