Small-scale distribution of juvenile gadoids in shallow inshore waters; what role does maerl play?
Abstract The indirect effects of demersal fisheries, such as habitat degradation, are currently thought to be impacting gadoid stocks. Maerl fulfils nursery area prerequisites for several invertebrate species, so its role in similar ecosystem service provision for gadoids has been addressed. Juvenil...
