Lepomis auritus ( valencia )

tarjonnut wikipedia CA

Lepomis auritus és una espècie de peix pertanyent a la família dels centràrquids.[5]

Descripció

  • Pot arribar a fer 30,5 cm de llargària màxima (normalment, en fa 10,8) i 790 g de pes.[6][7][8][9]

Reproducció

Té lloc entre l'abril i l'octubre. Els ous són dipositats en nius bastits pels mascles en el fons de rius i llacs.[10]

Alimentació

Els adults mengen insectes terrestres i aquàtics (sobretot, libèl·lules i efemeròpters), mentre que els juvenils es nodreixen d'organismes bentònics (com ara, larves de dípters).[11]

Hàbitat

És un peix d'aigua dolça, demersal i de clima temperat (4°C-22°C; 47°N-28°N), el qual habita els gorgs sorrencs i rocallosos dels rierols i dels rius petits i mitjans, i, també, els marges rocallosos i amb vegetació dels llacs.[12][6]

Distribució geogràfica

Es troba a Nord-amèrica: rius orientals dels Estats Units i del Canadà.[13] Ha estat introduït a Mèxic, Alemanya (l'any 1895), Itàlia i Puerto Rico.[14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]

Estat de conservació

Les seues principals amenaces són les preses i la contaminació de l'aigua. A més, la introducció del peix gat de cap pla (Pylodictis olivaris) pot influir negativament en la seua supervivència.[29][10]

Observacions

És una plaga potencial car s'hi han donat informes d'impacte ecològic negatiu després de la seua introducció, ja que és una espècie apreciada pels afeccionats de la pesca esportiva.[27][6]

Rotbrust-Sonnenbarsch ( saksa )

tarjonnut wikipedia DE

Der Rotbrust-Sonnenbarsch (Lepomis auritus), auch Großohriger Sonnenbarsch genannt, ist ein Fisch aus der Familie der Sonnenbarsche (Centrarchidae).[1][2] Der Name Großohriger Sonnenbarsch wird unter anderem für diese Art (Lepomis auritus) verwendet, primär jedoch für Lepomis megelotis.[3]

Merkmale

Der Rotbrust-Sonnenbarsch besitzt einen gedrungenen, hohen und seitlich abgeflachten Körperbau. Der recht lange und schmale Fortsatz des Kiemendeckels ist schwarz[3] und besitzt keinen andersfarbigen Rand.[1] Die Körperfärbung ist charakteristisch, bei männlichen Jungtieren die die Geschlechtsreife erreicht haben jedoch mehr ausgeprägt als bei älteren Tieren oder Weibchen. Diese Tiere werden am Rücken olivbraun bis braunviolett, an der Seite sind sie grünlich und grau, danach verläuft der Farbton in eine gelbgrüne Farbmischung. Die Kehle, die Bauchunterseite als auch die Brustflossen sind intensiv orangerot gefärbt. Unterhalb der Augen lassen sich hellblaue Wellenlinien und Tupfen finden.[3] Die Rückenflosse der Tiere wird in zwei unterschiedliche Teile eingeteilt[1] und die Schwanzflosse ist in der Mitte leicht eingekerbt.[4] Die Fische werden zwischen 12 und 15 Zentimeter groß und ca. 700 Gramm schwer.[1]

Lebensweise

Diese Art ernährt sich primär von Wirbellosen, anderen Fischen und vor allem von Insektenlarven.[1] Aber auch von ausgewachsenen Insekten wie etwa Eintagsfliegen oder Libellen. Sie lässt sich im Süßwasser finden, in steinigen und sandigen Arealen von kleinen bis mittelgroßen Flüssen und am Rand von Seen.[2] Von Juni bis Juli ist die Laichzeit der Fische.[1] Das Weibchen legt in eine flache Mulde, in einem sandigen und/oder feinkiesigen Untergrund, etwa 1000 Eier ab. Gut genährte Weibchen können bis zu 2000 Eier legen, dies geschieht an einer flachen Stelle des Gewässers. Danach verlässt das Weibchen die Mulde mit den Eiern und zieht sich in tiefere Gewässer zurück. Wie bei allen anderen Sonnenbarscharten übernimmt auch das Männchen die Brutpflege. Es bewacht die Eier und die frisch geschlüpften Fischlarven. Die Geschlechtsreife erreichen die Fische bereits im zweiten Lebensjahr.[3]

Verbreitung

Sein natürliches Verbreitungsgebiet umfasst den Osten der Vereinigten Staaten, von Maine bis Virginia.[3] Er wurde jedoch auch in Teilen Italiens eingeführt.[1]

Aquaristik

Der Rotbrust-Sonnenbarsch erfreut sich Beliebtheit unter Aquarianern und kann in einem Kaltwasseraquarium oder Gartenteich gehalten werden. Er braucht klares und sauberes Wasser vorzugsweise mit einer leichten Strömung, daher sollte man eine Filteranlage sowie eine Umwälzpumpe beziehungsweise eine Förderpumpe besitzen. Außerdem braucht der Fisch möglichst konstante Wasserwerte, wobei der pH-Wert im Bereich zwischen 7 und 7,5 liegen sollte. Da sich dieser Sonnenbarsch unter anderem von kleinen Fischen ernährt sollte man ihn nicht mit anderen kleineren Fischarten zusammen halten. Des Weiteren sollte man den Fisch in einem Kaltwasseraquarium überwintern und vor Frost schützen.[3]

Redbreast sunfish ( englanti )

tarjonnut wikipedia EN

The redbreast sunfish (Lepomis auritus) is a species of freshwater fish in the sunfish family (family Centrarchidae) of order Perciformes. The type species of its genus, it is native to the river systems of eastern Canada and the United States. The redbreast sunfish reaches a maximum recorded length of about 30 centimetres (12 in).

The species prefers vegetated and rocky pools and lake margins for its habitat. Its diet can include insects, snails, and other small invertebrates. A panfish popular with anglers, the redbreast sunfish is also kept as an aquarium fish by hobbyists. Redbreast sunfish are usually caught with live bait such as nightcrawlers, crickets, grasshoppers, waxworms, or mealworms. They can also be caught using small lures or flies. Most anglers use light spinning tackle to catch redbreast sunfish. It is popular with fly anglers in the winter because it will more readily strike a moving fly than will bluegills in cooler water.

As is typical for the sunfishes, the female redbreast sunfish lays her eggs (about 1000) in a substrate depression built by the male.[2] The male guards the eggs and fry.

The specific epithet, auritus, is Latin for big-eared.

Description

The average length of the redbreast sunfish is around 11 centimetres (4 in) with a record 30.5 centimetres (12.0 in). The record weight for the fish is 0.79 kilograms (1.7 lb). The redbreast sunfish is characterized by a long black opercular flap, which is longer than those of most other sunfish in its range.[3] There are a few blue iridescent vermiculations on the head. Small teeth may be appreciated, mostly on the roof of the mouth.[3][4] There are faint vertical bars present on the olive-green bodies of both sexes, which may become more apparent as the background coloration changes to blue-green near the lateral line.[3][5] Males have darker ventral coloration than that of females, ranging from orange-yellow to orange-red.[3] The caudal fin has a shallow fork and may have orange to red pigmentation.[3] It is common within the redbreast sunfish's native and introduced range for hybridization with other sunfish species to occur.[6]

Distribution

The species' native range is in the eastern United States and Canada, in rivers emptying into the Atlantic Ocean. The redbreast sunfish tends to be more of a cool-river species, but also inhabits freshwater lakes and streams. The species has been introduced as far west as Louisiana and West Texas.[6] Lepomis auritus has been transplanted to and become established in Germany, Italy,[7] Mexico,[8] and Puerto Rico.[6] The effects of introduced populations of redbreast sunfish on native species are not well studied.[6]

Ecology

Redbreast sunfish mainly consume immature aquatic insects. Mayflies, small fish, and dragonfly larvae consist of the majority of the sunfish's diet based on stomach content. Small crayfish may also be consumed. Being an opportunistic feeder, the fish competes with other sunfish and larger predatory fish that prey on the same food they do.

Larger piscivorous fish are the main predators of smaller redbreast sunfish. Micropterus species are a major threat to sunfish because of shared habitat and the availability of the sunfish. The sunfish prefers structure around banks and overhanging branches that provide food, shade and protection. Lepomis auritus survives best in water with current and a pH between 7.0 and 7.5.[2] Lack of current or too acidic or basic water can dramatically affect the sunfish's survival rate.

Human influence on abiotic factors, such as sunlight, and biotic factors, such as predator numbers, can have a major influence on sunfish. Clearing debris from the bank can increase the amount of sunlight that reaches the water, thus increasing water temperature, while also decreasing the number of hiding places along the bank that sunfish can use. Decreasing the number of larger predatory fish by harvesting them will increase the survival rate of the redbreast sunfish.

Life history

The redbreast sunfish is a spring spawner on sand-gravel substrate depending on location, or when water temperature reaches 16–26 °C (61–79 °F). According to Stanley Sharp, "The mature male generally builds a nest in shallow water or may simply use the abandoned nest of another Centrarchid. The female eventually enters the nest, releases her adhesive eggs for fertilization while swimming with the male, and then leaves. The male remains to guard and fan the eggs and possibly even to guard the young for a brief period. The male and female will then move out of the shallow water after spawning and into deeper water. A male sunfish will breed with more than one female, just as female sunfish will breed with more than one male. Average egg production for the sunfish is around 3000 depending on the age of the female.[9] Mature ova are around 2.1 millimetres (0.083 in) in diameter.[9] Reproductive maturity is reached the second year of life. They have been known to have a maximum lifespan of around eight years.[3] Currently, humans do not play a large role in influencing life history due to large populations and secluded areas.

Relationship with humans

Management

Currently, the redbreast sunfish is not on the federal or state endangered or threatened species list. The species is thriving in its natural habitat.

Angling

The IGFA all tackle world record for the species stands at 0.79 kilograms (1 lb 12 oz) caught from the Suwannee River in Florida in 1984.[10] A Georgia state record fish caught in the Satilla River in May 2022 tied the world record.[10][11] A North Carolina state record fish caught on the Lumber River in 2019 weighed 2 pounds 1 ounce (0.94 kg).[12]

Lepomis auritus ( Italia )

tarjonnut wikipedia IT
RedbreastedsunfishtallapoosaRiver.jpg

Lepomis auritus Linnaeus, 1758) è un pesce osseo d'acqua dolce della famiglia Centrarchidae.

Descrizione

È molto simile al persico sole comune in Europa, si può distinguere facilmente per avere sul bordo dell'opercolo una sporgenza piuttosto sviluppata con una macchia nera all'apice mentre nel persico sole la macchia è rossa ed ha un bordo chiaro.

Raggiunge i 30 cm di lunghezza ma la misura media è attorno ai 10.

Biologia

Alimentazione

Si nutre di invertebrati acquatici: insetti caduti in acqua gli adulti e larve bentoniche i giovanili.

Distribuzione e habitat

Questa specie, come tutti i Centrarchidae, è originaria dell'America settentrionale, più precisamente della costa atlantica. È stato introdotto in vari paesi ma pare che non si sia naturalizzato in Europa[2].

Vive di solito in ruscelli e piccoli fiumi con fondali di roccia o sabbia, e nella zona costiera ricca di vegetazione dei laghi.

Pesca

Solo sportiva e perlopiù occasionale.

Roodborstzonnebaars ( flaami )

tarjonnut wikipedia NL

Vissen

De roodborstzonnebaars (Lepomis auritus) is een straalvinnige vis uit de familie van zonnebaarzen (Centrarchidae) en behoort tot de orde van baarsachtigen (Perciformes). De vis is gemiddeld 11 cm lang, maar kan echter tot maximaal 30,5 centimeter lang en 790 gram worden.

Leefomgeving en voedsel

De roodborstzonnebaars is een zoetwatervis, maar komt soms ook voor in brak water. Het natuurlijke verspreidingsgebied is Noord-Amerika in het oostelijk deel van Canada en de Verenigde Staten. De roodborstzonnebaars komt daar vooral voor in plassen en beken met een zand- of rotsbodem en aan de stenige en begroeide oevers van rivieren en meren.

De roodborstzonnebaars leeft van macrofauna en dan vooral op insecten als haften en echte libellen, waterinsecten, zeeslakken en andere kleine ongewervelden.

Relatie tot de mens

De roodborstzonnebaars is voor de beroepsvisserij van geen enkel belang. Er wordt wel op de vis gehengeld. De soort wordt verder gevangen als aquariumvis. De soort kan worden bezichtigd in sommige voor een groot publiek toegankelijke aquaria.
De vis komt als exoot voor in Mexico en Puerto Rico en in Europa (o.a. Duitsland en Italië). Deze vissoort komt niet voor op de lijst van in Nederland schadelijke exoten van de werkgroep exoten.[3]

De soort staat op de Rode Lijst van de IUCN als niet bedreigd, beoordelingsjaar 2007. De omvang van de populatie is stabiel.[1]

Rödbröstad solabborre ( ruotsi )

tarjonnut wikipedia SV

Rödbröstad solabborre (Lepomis auritus) är en sötvattensfisk i familjen solabborrfiskar, som är vanligt förekommande i stora delar av Nordamerika.

Utseende

En fisk med hög kropp, en mörkbrun till olivfärgad rygg som övergår i ljusare olivfärgade sidor och en buk som är gul hos honorna, rödaktig hos hanarna. Under parningstiden får hanen röda fläckar längs sidorna och blå läppar.[2] Kinder och gällock har flera oregelbundna, blåaktiga ränder. Den har en avlång, svart fläck på gällockets förlängning.[3] Fisken kan som mest bli drygt 30 cm lång och väga 790 g.[4]

Vanor

Den rödbröstade solabborren lever i bäckar och små till medelstora floder med klipp- eller sandbotten[4], men kan också förekomma sjöar och vattenreservoarer. Den är vanligt förekommande i bäverdammar.[2] Födan består av insekter och deras larver, små kräftor, små musslor, snäckor samt småfisk.[3] Ungarna lever på små bottendjur som tvåvingelarver.[4]

Arten kan bli 7 år gammal. Hanar förefaller bli äldre än honor.[2]

Fortplantning

Arten blir könsmogen under sitt 2:a levnadsår vid en längd på mellan 7,5 och 10 cm.[2] Den leker på våren, då hanen bygger ett grunt bo på grus- eller grov sandbotten i stilla vatten på ringa djup (drygt 1 meter).[3] Honan lägger mellan 300 och 9 200 ägg i boet, varefter hanen vaktar äggen. Den rödbröstade solabborren är den enda arten i sin familj där hanen inte ger läten ifrån sig under parningen.[3]

Utbredning

Artens ursprungsområde var vattendrag i östra Kanada och USA.[4] Den har introducerats utanför ursprungsområdet, bland annat i Texas och Louisiana.[2]

Kommersiell och ekologisk betydelse

Den rödbröstade solabborren är en populär sportfisk. Inplanteringar, bland annat i Mississippifloden, har dock visat sig få negativa konsekvenser för den lokala fiskfaunan.[2]
