文摘
- •
Maximum length of Atlantic surfclams (Spisula solidissima) has decreased by 20 mm.
- •
Possible drivers (fishing & temperature) were investigated with population models.
- •
Increasing bottom water temperature by 2 °C can cause the observed change.
- •
Sustained fishing at 20% can also cause the observed change.
- •
Interannually varying water temperatures can cause the observed change.
