The spider crab M aja brachydactyla is an important fisheries species in E urope. Adults were sampled in R ía de A C oruña ( NW S pain) and transported to IRTA rearing facilities. Salinity and photoperiod changes and their effect on reproduction were tested in the laboratory. The number of newly hatched larvae per batch (presence of actively swimming newly hatched larvae in a broodstock tank) was counted and sampled to estimat...

The spider crab M aja brachydactyla is an important commercial species in E urope and supports intensive fisheries in the NE Atlantic. A field survey was performed to assess long‐term and consecutive interannual (2005–2010) variation of the biochemical composition of newly hatched larvae of M . brachydactyla . L arval biochemical profiles differed significantly among years, with pronounced differences being recorded in 2010. D...
