A total of 1217 individuals were sampled monthly from both offshore bottom trawling and inshore small-scale fishery off Mallorca Island’s coast (western Mediterranean) during 2017–2019. Inshore individuals were larger than the individuals inhabiting offshore and males were more abundant than females both inshore and offshore waters. The estimated size at first maturity (L50) was 87 mm for females and 78 mm for males. S. officinalis has a semi-continuous reproduction cycle throughout the year with a spawning peak between March and June. Oocyte size-frequency distribution (OSFD) analysis showed an asynchronous oocyte development. Advanced mode fecundity (FAM) ranged between 8 and 326 oocyte/female with a mean of 158 ± 14 oocyte/female. The Stomach Fullness Index (SFI) was found to decrease during reproductive development in inshore specimens, while the stomach vacuity index (SVI) followed the opposite trend for both inshore and offshore individuals, indicating a lessening of the feeding activity specially during spawning. However, once at shallower waters, spawning females displayed higher SFI values compared to males, which was probably linked to the higher energetic demand associated with reproduction. Digestive gland index (DGI) showed little variation in females across maturation stages, while males’ values decreased, especially during spawning, reflecting sexual differences in the energy allocation strategy. Those results suggest that common cuttlefish fulfil the cost of reproduction through both current food intake and accumulated somatic reserves This project has been co-funded by the EU through the European Maritime and Fisheries Fund (EMFF) within the National Program of collection, management and use of data in the fisheries sector and support for scientific advice regarding the Common Fisheries Policy With the institutional support of the ‘Severo Ochoa Centre of Excellence’ accreditation (CEX2019-000928-S) Peer reviewed 2023-06-23T11:08:31Z 2023-06-23T11:08:31Z 2023-05 artículo Marine Biology 170: 69 (2023) 0025-3162 CEX2019-000928-S http://hdl.handle.net/10261/329571 10.1007/s00227-023-04213-4 1432-1793 en Preprint https://doi.org/10.1007/s00227-023-04213-4 Sí open Springer |
