Age, growth and mortality were analysed for the common twobanded seabream, Diplodus vulgaris, collected in the eastern Adriatic (Croatian coast) from commercial fishery catches by ÔtramataÕ fishing (2005)(2006) to obtain growth estimation. The oldest female was estimated to be age 11, the oldest male age 10 years. The von Bertalanffy growth parameters estimated by reading scales were: L ¥ = 48.60 cm (SE = 1.101), K = 0.112 (SE = 0.005) and t 0 = )2.366 (SE = 0.060) for all specimens; L ¥ = 51.96 cm (SE = 2.153), K = 0.095 (SE = 0.007) and t 0 = )2.837 (SE = 0.120) for females and L ¥ = 56.25 cm (SE = 2.662), K = 0.084 (SE = 0.067) and t 0 = )2.920 (SE = 0.117) for males. The overall sex ratio was 1.22 : 1 in favour of males. Total mortality, corresponding to the slope of the descending limb of the catch curve, was Z = 0.81 per year for females and Z = 0.85 per year for males. Exploitation ratios were E = 0.68 for females and E = 0.73 for males.

Dulčić J., Dragičević B., Grgičević R., Lipej L. 2011. First substantiated record of a Lessepsian migrantthe dusky spinefoot, Siganus luridus (Actinopterygii: Perciformes: Siganidae), in the Adriatic Sea. Acta Ichthyol. Piscat. 41 (2): 141-143.Abstract. One specimen of the dusky spinefoot, Siganus luridus (Rüppell, 1829) (♀, total length = 17.3 cm, total weight = 87.61 g), a lessepsian migrant, was captured in the Mljet Channel (Southern Adriatic, Croatian coast) on 15 November 2010. This is the second record of this species from the Adriatic, but first well documented and based on the captured specimen. First record occurred earlier in the Northern Adriatic, but was based solely on underwater observations.

The king of herrings also known as the oarfish, Regalecus glesne Ascanius, 1772, is an open water mesopelagic species occurring in most tropical and temperate areas of the World Ocean (Froese and Pauly 2010), but is quite rare in the whole area of its wide distribution. King of herrings can be found at depths down to 1000 m, but can also be encountered near the surface (Bauchot 1987). Its global distribution and movements in the water column reveal an extensive migratory pattern both at vertical and horizontal axis. However, most records of this fish are based on stranded or moribund specimens found near the coasts and sightings of live fish in its natural habitat are very rare (Schmitter-Soto 2008). The fact that this fish inhabits greater depths and is therefore unavailable to most fishing gears probably adds to the perceived rarity of the species.King of herrings has a band-like body, laterally compressed and extremely elongated. It is considered as the longest known teleost, being able to reach lengths of up to 11 m (Eschmeyer et al. 1983). It's enormous occipital crest, long pelvic fins, vivid coloration of fins, unusually shaped head and it's greatly elongated body leave a little space for the misidentification of the adult specimens of this species.This species is also present in the Mediterranean where it is considered very rare (Tortonese 1970). However, it is more common in certain areas such as the Liguro-Provencal basin where the findings of adults specimens are more frequent (Psomadakis et al. 2008). Adults,
