Reproductive strategies under different environmental conditions: total output vs investment per egg in the slipper lobster Scyllarus arctus
Abstract The slipper lobster Scyllarus arctus is an important fishery resource in Galicia (NW Iberian Peninsula), with a large reduction of its populations in recent decades in the North-east Atlantic and Mediterranean, but only limited information on its reproduction. This study provides an analysi...
