“…Possible consequences of this phenomena are: (1) dwarfing or "stunting" as a result of the rapid expansion of the pumpkinseed sunfish population producing large numbers of individuals which mature and breed at a much reduced size; (2) interspecific competition due to the egg predation of native fishes specially A. scabripinnis; and (3) progressive diminution of A. scabripinnis population in the dam, which according to the old habitants in the area, occurred along the 38 years of introduction of this centrarchid. Similar observation was noticied by VOOREN (1972) who related that stunted populations of the introduced redbreast sunfish Lepomis auritus (Linnaeus, 1758) in Italian mountain lakes, has supplanted the native Alburnus alborellus (Linnaeus, 1758) due to the intensive predation on eggs and alevins.…”

The reproductive biology of the introduced pumpkinseed sunfish Lepomis gibbosus (Linnaeus, 1758) in the Custódio's Dam, rio Doce high basin, state of Minas Gerais, Brazil was studied from February/2001 to March/2002 and compared with introduced and native populations. Reproduction occurred almost along the entire period of study with a high frequency of fishes in the advanced ripening/mature and spawned/spent stages. The microscopic analyses indicated that the pumpkinseed sunfish presents multiple spawning. The egg diameter of the Brazilian population is similar to the Spanish, Greek and American ones. The standard length at maturity and the gonadosomatic index of the introduced populations are smaller when compared with native ones. The spawning season of the Brazilian population was the longest among all comparisons made in the present work.

“…Based on experience from North America, one might predict that brook trout should be unable to establish populations if the competitively dominant native species, brown trout, is present. Therefore, fisheries managers have assumed that brook trout does not pose a serious threat to brown trout or other native fish in European streams (13). Here we show that biotic interactions among stream salmonids can be strongly context-dependent and that a species inferior in its native range can become an effective invader when transferred to areas where the presumably superior competitor is the native species, provided that the characteristics of the new environment are favorable for the invader.…”

“…Brown trout is also a dominant competitor in New Zealand and Japanese streams (11,12), having far-reaching effects on lotic food webs (11), and it has been listed as one of the 100 worst alien species in the world by the Invasive Species Specialist Group. In contrast, there is no rigorous documentation of the impact of brook trout on native salmonids in European streams, although the species has been introduced to a number of streams throughout the continent (13,14). Based on experience from North America, one might predict that brook trout should be unable to establish populations if the competitively dominant native species, brown trout, is present.…”

An ability to understand and predict invasions is elemental for controlling the detrimental effects of introduced organisms on native biota. In eastern North America, European brown trout generally dominates over, and eventually replaces, the native brook trout. We show here that in northern Europe the pattern of replacement between these two species is reversed: when transferred to North European streams, brook trout spread extensively and partially replaced the native brown trout. The effect of brook trout on brown trout was habitat-specific: brook trout excluded the native species only in small tributary streams where the reproduction of brown trout was severely reduced, whereas in larger streams brown trout was largely unaffected. Thus, the pattern of coexistence among the two salmonids in our study area is approaching that typically observed in North American streams. In both areas, brook trout ultimately settles in small headwater streams, but the process of replacement differs profoundly: in North Europe, brook trout replaces brown trout in headwater streams, whereas in North America these same streams are the ultimate refuge area for brook trout under the invasion pressure by brown trout. Our results underline the importance of knowing species' niche characteristics to explain and predict biological invasions.alien species ͉ biological invasions ͉ trout

“…On juge donc que pour sa valeur écologique, pour les caractéristiques de l'espèce et pour le bon rendement de transformation, le black-bass pourrait être pris en considération plus attentivement et employé pour le repeuplement des eaux. A l'opposé de plusieurs espèces allopatriques (VOOREN, 1972), il a montré une très bonne adaptabilité et surtout s'est révélé extrê-mement utile. Son emploi, toutefois, devra être programmé et soigneusement contrôlé, sous peine de dommages imprévisibles à rencontre du milieu.…”

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...
