“…The specimens were frozen immediately after capture and transported to the laboratory where total (TL) length was measured to the nearest 0.1 mm using digital callipers and body weight (W) to the nearest 0.001 g using an analytical scale. Juveniles were defined according to the time of spawning (Gordo, 1995;Matic´-Skoko et al, 2004;Criscoli et al, 2006;Monteiro et al, 2006;Pallaoro et al, 2008;Correia et al, 2011), duration of the larval stage (Ravento´s and Macpherson, 2001;Correia et al, 2011), and total body length when they reach sexual maturity (Gordo, 1995;Gonc¸alves et al, 2003;Criscoli et al, 2006;Monteiro et al, 2006;Pallaoro et al, 2008;Mouine et al, 2010).…”

“…Bogue Boops boops is a semipelagic species commonly found at depths of < 150 m on various types of bottoms and, as most other pelagic species, uses mainly coastal shallow areas as a nursery (Monteiro et al, 2006). Common two-banded seabream Diplodus vulgaris is abundant in the sublittoral rocky bottoms up to 100 m depth (Gordoa and Molı´, 1997), whereas the juveniles live in coastal lagoons and estuaries (Gonc¸alves et al, 2003;Vinagre et al, 2010;Correia et al, 2011).…”

Summary The food compositions of salema Sarpa salpa, bogue Boops boops and common two‐banded seabream Diplodus vulgaris in Donji Molunat Bay (south‐eastern Adriatic) were studied in order to evaluate the diet overlap among them. Fish were collected from March to July 2009 using a beach seine net. Three species of crustaceans were the most common prey, the most abundant being copepods. A significant overlap in the diet calculated using Schoener's index was recorded in May when the index was 0.9266 for bogue and salema, 0.6091 for bogue and common two‐banded seabream, and 0.6142 for common two‐banded seabream and salema.

“…This element may be important in the case of D. vulgaris because the spatial use patterns of adults and potential spawners remain unknown. Spatial data have been obtained for subadults in nursery areas (Abecasis et al, 2009), as well as demonstrated using otolith microchemistry (Correia et al, 2011), however, information on the spatial behavior in habitats occupied by adults remains unavailable.…”

“…Two methods are frequently used and updated and thus regularly offer new innovations (Ludsin et al 2006, Arevalo et al 2010: solution-based ICP-MS and laser ablation-ICP-MS (LA-ICP-MS). The first consists of transferring trace elements from the otolith to a solvent and often needs an extraction/preconcentration step (Arslan 2005, Correia et al 2011 prior to the ICP-MS analysis. Transect determination and core analysisproviding information on migrations and natal origin, respectivelyare difficult to assess with this methodology because this technique is generally based on the analysis of the whole otolith.…”

This article proposes a methodology to analyse the composition of very small carbonate samples such as larval fish otoliths. The chemical composition of otoliths, which are carbonate structures in the inner ear, is often used to explore population dynamics in fishes. Recent advances in laser ablation‐inductively coupled plasma‐mass spectrometry have suggested its potential application to this field. In this study, analyses were performed using a 193 nm ArF Resonetics LA system, coupled to an Agilent 7700X‐ICP‐MS, with the following ablation parameters: a beam diameter of 5 μm, energy of 3 mJ, 2.7 J cm−2, laser repetition rate of 10 Hz and translation speed of 2.5 μm s−1. NIST SRM 610 glass was used as the primary calibration material. Performing this protocol, characterisation of a USGS GP‐4 reference material was achieved with suitable precision and accuracy, but the USGS MACS‐3 reference material appeared more heterogeneous under the ablation conditions tested. Calibration was performed using two different beam diameters (5 and 11 μm). Capelin (Mallotus villosus) otoliths measuring between 10 and 20 μm in diameter were tested. Even though a smaller beam diameter and lower energy were used compared with those normally employed to analyse larger otoliths, the method was successful.
