Effect of temperature on the growth of the commercially fished common whelk (Buccinum undatum, L.): A regional analysis within the Irish Sea

Abstract

Effect of temperature on the growth of the commercially fished common whelk (Buccinum undatum, L.): a regional analysis within the Irish Sea.

The effect of environmental factors on shell growth and repair in Buccinum undatum

“…In some gastropod species certain environmental conditions (e.g., a combined change in pH and elevated seawater temperature) have been observed to reduce morphological size and have a negative effect on growth, as observed, for example, in the periwinkle (Littorina saxatilis) and gold-ringed cowry (Monetaria annulus) (Sokolova and Pörtner, 2000;Irie and Fischer, 2009;Melatunan et al, 2013). Observations from our study support previous work into metabolism and temperature, with increased temperatures causing an increased rate of growth, up until the thermal tolerance is reached (Emmerson et al, 2020;Borsetti et al, 2021).…”

“…For some species, e.g., the common whelk, Buccinum undatum, somatic and shell growth is continuous throughout life (Kideys et al, 1993). As such, B. undatum displays a predictable relationship between size and age, which has been used to determine growth rates in several studies (Hollyman et al, 2018;Emmerson et al, 2020;Borsetti et al, 2021).…”

Impact of mechanized clam dredging on the discarded megabenthic fauna on the Catalan coast (NW Mediterranean)

“…(2003) stated that between 16.88 and 42% of individuals dislodged and left in the dredge path showed partial damage, while between 16.88 and 29.17% showed severe damage. The gastropod Buccinum undatum is frequently discarded by scallop dredging activity in Anglesey (Irish Sea) (Emmerson et al ., 2020). This gastropod is returned to the sea without external damage and the first studies estimated 100% survival after being dropped (Kaiser & Spencer, 1995).…”

Calibration of shell δ18O from the common whelk Buccinum undatum highlights potential for palaeoenvironmental reconstruction

“…This explanation assumes the EFP of B. undatum is largely isolated from surrounding seawater, something which has not been confirmed. Lastly, the offset between δ 18 O exp and δ 18 O S could simply be due to differing δ 18 O values of the EPF and seawater caused by a physiological control of the EPF composition (Thébault et al, 2007) (Emmerson et al, 2020), the methods outlined here could prove useful in informing the future management of this species.…”
