Title:Growth patterns of the most abundant lanternfish, Ceratoscopelus maderensis (Lowe, 1939), in the western Mediterranean Sea
Issue No.:2
Abstract:The age and growth patterns of the mesopelagic fish Ceratoscopelus maderensis (Family Myctophidae) of the western Mediterranean were described throughout its entire life cycle (larvae, transformation, juvenile, and adult stages) using the sagittal otoliths of 59 individuals collected in December 2009. Three characteristic zones were dentified along the sagittal section of the otolith (larval, metamorphic, and juvenile-adult zones). Assuming growth rings as daily increments, the age of the analyzed individuals(from 3.5 to 64 mm standard length [SL]) would range from 7 to 332 days. The relationship between the number of increments and the fish SL was fitted to a von Bertalanffy’s growth model. The growth pattern of C. maderensis in the western Mediterranean was similar to that reported for this species in the Atlantic Ocean. Nevertheless, the western Mediterranean individuals showed faster growth, likely due to the higher temperature regime of the Mediterranean Sea when compared to the Atlantic Ocean. While Mediterranean individuals achieved a SL of 60 mm in 361 days, individuals from the Atlantic Ocean would have required 394 days to reach the same body length.
