RÉSUMÉLe black-bass à grande bouche est largement répandu dans les eaux italiennes et fait l'objet de repeuplement. Les alevins et estivaux nécessaires proviennent le plus souvent de la vidange automnale des étangs à cyprinidés avec lesquels ils sont élevés.Il n'y a pas vraiment d'élevage contrôlé de cette espèce en Italie, mais seulement une série d'essais qui portent sur la reproduction naturelle en étangs-frayères, l'introduction de nids artificiels dans le milieu et l'induction de la ponte par traitement hypophysaire (avec HCG), essais qui donnent des résultats satisfaisants.Dans le milieu naturel, la croissance en longueur et en poids du black-bass en Italie est comparable et quelquefois meilleure que celle enregistrée sur ses lieux d'origine. La croissance annuelle est d'abord lente (printemps), puis rapide (été), ensuite à nouveau lente (automne) pour être finalement modeste ou pratiquement nulle en hiver.La population qui, avec des fluctuations annuelles, représente 0,5 à 1,6 % de l'ichthyofaune des eaux étudiées (fleuves Pô, Sesia et Ticino), est constituée surtout de sujets jeunes : environ 40 % des individus sont âgés de 2 hivers et ne dépassent pas un poids de 400 g et une longueur totale de 28 cm. La survie est considérée comme bonne avec une durée de vie de 8 à 9 hivers. La nourriture présente un spectre très large et est basée de préférence sur des petits poissons et sur les amphibiens, avec une large partie d'invertébrés (surtout des insectes). La reproduction intervient aux mois de mai et juin, mais elle peut être aussi plus précoce et, le plus souvent, plus tardive. Le black-bass est très sensible aux pollutions, mais ne semble pas particulièrement affecté par des épizoo-ties ou du parasitisme.Par rapport à la niche écologique occupée, à son spectre trophique, à son rôle dans les équilibres biologiques et à ses caractéristiques éthologiques, le black-bass ne peut pas être considéré comme un antagoniste du brochet, exclusivement carnassier et prédateur, avec lequel il peut même cohabiter. SUMMARY The black-bass, Micropterus salmoides (Lacép.), in Italian waters. A competitor of pike ?The black-bass, often used in restocking, is now a widespread species in Italy. " Seedlings " are often recruited from polycultural fish ponds when these are drained.Some fish farmers produce fry and summerlings in spawning ponds, but there is no actual rearing. Egg spawning and development in artificial nests have only recently been tested. Experiments to induce sexual maturity and spawning by injecting hypophyseal extracts and/or gonadotropines have also been tried with success.The dimensional and pondéral growth of black-bass in natural habitats is comparable to or even better than the growth usually reported. Yearly growth, at first slow (spring), increases (summer), then slows down again (fall) and finally becomes almost imperceptible or practically stops (winter).Accounting for annual fluctuations, the black-bass population in the waters we studied (Po, Sesia and Ticino rivers) made up 0.5 to 1.6 % of the tota...

Biological and ecological aspects of Lake Garda carpione, Salmo carpio L., are reported. This study reports lower catches and it is suggested that fewer carpione are now in this lake. Opercula and scales have been used for ageing fish and determining the growth rates. Life expectancy does not exceed five winters. Males became sexually active at 2 years ( = winters) of age and females at 3 years of age, however, full spawning capability is achieved only in the following year. Our data confirm that carpione have two spawning seasons: winter (a long period) and summer (a shorter one). Carpione are not exclusively planktivorous but adapt their feeding habits to the environment and change the manner and time of their feeding.

Le poetriae del medioevo latino Modelli, fortuna, commenti a cura di Gian Carlo Alessio e Domenico Losappio AbstractThis book offers a reflection upon Medieval Latin artes poetriae and aims to spur the scientific debate on them by means of eleven papers written by internationally-kwown scholars. The essays investigate, according to different perspectives and in different ways, various aspects of the artes: their relations with other texts (Latin and vulgar), their fortune, their sources, the cultural contexts in which they were read and commented, and single authors' reflections upon sp...

This collection of essays deals with Dante's relation to the five poets who form Limbo's "bella scola" and to the two, Statius and Terence, who might have been expected to be there. The first essay (by Amilcare A. lannucci, also the editor of the volume) analyzes the scene in Limbo in which Dante becomes "sesto tra cotanto senno." The second (coauthored by Gian Carlo Alessio-Claudia Villa) attempts to determine and describe more exactly the medieval reader's, and therefore Dante's, knowledge of Virgil. The next four articles examine questions about the remaining members of the "bella scola," Homer (Giorgio Brugnoli), Horace (Claudia VUla), Ovid (Michelangelo Picone), and Lucan (Violetta de Angelis). These are followed by a survey of the present state of studies on Dante and Statius (Luca Carlo Rossi) and an essay on Dante's relation to classical com-
