“…Prey availability also varies throughout the year, as is well documented in the GSL. Mackerel arrive in the GSL in late May and early June (Sette, 1950;D'Amours and Castonguay, 1992) and remain until October (McKay, 1979), whereas herring congregate to spawn in the spring, before the Atlantic bluefin tuna have arrived, and in the Autumn from August to the end of September (Messieh, 1987). The presence of gravid herring in the samples from Port Hood confirms that the Atlantic bluefin tuna in the GSL were feeding on the aggregations of Autumn spawners during sampling.…”

“…High presence–absence and given‐presence of mackerel DEP were associated with similar temperature range (approximately 10.5–16 and 10–16.5°C for PA and GP models respectively; Figures and). This dome‐shaped relationship linking both DEP presence–absence and given‐presence to temperature in our models suggests an optimal thermal window potentially driven by constraints linked to embryo development (Nwosu & Holzlöhner, ; Sapkale, Singh, & Desai, ) and the influence of temperature on adult mackerel distribution, migration and timing of spawning (D’Amours & Castonguay, ; Jansen & Gislason, ; Overholtz et al, ). The range of temperature (10–16.5°C) associated with mackerel DEP, with an optimum around 13–14°C (Figures and), is consistent with those described in models for the north‐east Atlantic mackerel (Bruge et al, ; Brunel, Damme, Samson, & Dickey‐Collas, ) and studies using egg survey data for the north‐west Atlantic mackerel stock (Studholme et al, ).…”

“…These variables were sea surface and averaged‐50m of temperature (SST and T0_50, respectively) and salinity (SSS and S0_50, respectively). SST and T0_50 were selected as water temperature influences Atlantic mackerel migration and timing of spawning (D’Amours & Castonguay, ; Radlinski et al, ). Although salinity is not or barely mentioned in studies of mackerel spawning habitat and larvae distribution (e.g.…”

“…Sampling. Mackerel enter the southern Gulf of St. Lawrence (sGSL, Eastern Canada) in early June each year to spawn, after overwintering along the north-eastern US continental shelf (from Sable Island to the Mid-Atlantic Bight 29,30 ). Each year, Fisheries and Oceans Canada (DFO) conducts a 2-week long mackerel egg survey in the sGSL (a 65-station fixed grid 20 nautical miles apart spanning the dominant mackerel Conceptual framework of the pathway from spawners to recruits and the underlying mechanisms investigated (stock demographic structure and environmental conditions in red and green, respectively).…”
