New data on Trachipterus trachypterus Gmelin, 1789 and Zu cristatus (Bonelli, 1820) (Pisces: Trachipteridae) from the Mediterranean Sea
In this paper we report data on four juvenile individuals of T. trachypterus and one adult of Z. cristatus, from the Strait of Messina and southern Tyrrhenian Sea, respectively (Mediterranean Sea). Information on morphometric and meristic characters are provided together with some biological data such as prey and age estimation. Only stomachs of T. trachypterus contained prey: copepods, amphypods and pelagic snails. The analisys of growth patterns in vertebrae of Z. cristatus allowed to estimate an age of 4 years for this individual. We also combined our data together with information from bibliographic sources and estimated the relationships between total length and standard length, as well as total length and body mass, for these two species.
