Summary of Invasiveness

Top of page

Introduced to Europe from North America in the late 1800s (Maes, 1898), L. gibbosus is now established in a minimum of 28 countries in Europe and Asia Minor (Copp and Fox, 2007), with a population reported for Brazil and possibly also Chile. Initial reports (early 1900s) mentioned large specimens but with repeated introductions needed for establishment. Later in the 1930s, the species was blamed for the decline of native Eurasian perch (Perca fluviatilis), but this hypothesis was never tested. There is little direct evidence of adverse impacts except from Iberia. Few parasites are reported, though non-native monogeneans have been reported for Norwegian and English populations. Invasiveness in L. gibbosus appears to be a function of juvenile growth (length at age two) and age at maturity, with invasive populations reported almost exclusively for southern Europe, However, even in northern Europe, L. gibbosus may represent a considerable proportion of the fish assemblage in water bodies that have been subjected to human impacts. The species is not listed on any conservation alert list.

Description

Top of page

L. gibbosus is a very deep-bodied, laterally compressed, almost disc-like fish, usually 178–229 mm in total length. However, it can reach sizes up to 40 cm in total length, with weights normally less than 450 grams. The fish present an oval silhouette and are very compressed laterally. Body pigmentation includes orange, green, yellow, or blue speckles on an olive back, yellow sides and a yellow to orange belly and breast. As with all centrarchids, they have sharp spines in the dorsal and anal fins. Scott and Crossman (1973) provided the following detailed description: “The greatest body depth at the fifth or sixth dorsal spine, 27.8–42.5% of total length, angle from snout to origin of dorsal fin steep, back humped, rounded even under dorsal fins; caudal peduncle longer than deep, its depth 10.7–15.1% of total length. Head quite deep, rather long, length 26.1–31.5% of total length, narrow, angle steep, pronounced hollow over eye, opercular flap flexible only at tip, black at centre with narrow, coloured border and red spot; eye moderately large, diameter 21.7–36.1% of head length, ahead of center of head and moderately high; snout length 19.5–29.0% of head length; mouth terminal, only slightly oblique, rather small, gape reaching only to anterior nostril; maxillary short, 27.3–36.0% of head length, reaching to posterior nostril or anterior edge of eye; many short needle-like teeth in brushlike patches on jaws, and a single row on vomer, no palatine teeth; lower pharyngeal teeth, on pads at least half as wide as long, fewer, low, blunt and paved. Gill rakers short, stubby, about 8 on lower limb, 4 on upper. Branchiiostegal rays 6, 6 and 7, or 7. Fins: dorsals 2, broadly joined and appear as one, base of dorsal fins 45.6–49.6% of total length, usually at least twice length of anal base; first dorsal long, spiny, moderate height, 10 or 11 spines but usually 10, not great differently in length, last spine about two-thirds that of second dorsal; second dorsal soft rayed, higher but with base only two-thirds that of first dorsal, rays 10–12, usually 11, edge shallowly rounded; caudal only moderately broad, somewhat longer, shallowly forked, tips rounded; anal fin with base 22.8–25.7% of total length, less than half dorsal base, 3 sharp spines precede the 8–11 (usually 9) soft rays, base of spiny portion about one-third length of base of soft part; pelvic thoracic origin under first or second dorsal spine and 5 soft rays, fin moderately long, tip pointed, edge square; pectorals moderately high on body, not overly broad but long and pointed, length 20.5–30.0% of total length, 12–14, but usually 13 rays. Scales usually ctenoid, not large, crowded dorsally front and rear; lateral line complete, high with long shallow arch over pectoral fin, 35–47 lateral line scales. Peritoneum silvery; intestines well differentiated, usually 7 or 8 moderately long pyloric caeca. Vertebrae almost always 29, rarely 28.

Colour: Dorsal surface of head, body, and upper sides golden brown to olive, lower sides golden with irregular, wavy, interconnecting blue-green lines, ventral surface bronze to red-orange; sides of body and head flecked with spots of olive, orange or red and with blue, emerald, or green reflections. Sides with several vague vertical bars; sides of head with prominent, wavy, blue-green stripes; pupil of eye black, a narrow, iridescent, golden ring around this and larger area brownish dorsally, blue-green ventrally; opercular flap with wide, black centre, a narrow border with white, yellow, orange or blue with small half moon spot of bright red (sometimes orange, pink or yellow) at tip; leading edge of dorsal spines black, membranes of second dorsal, caudal, anal, and pelvic fins black, but no pronounced or distinct large black spots, small vague orange to olive spots on membranes of second dorsal and caudal fins, leading edge of pelvic whitish, trailing edge of second dorsal, caudal, and anal with narrow, iridescent yellow or blue-green edge; pectoral fins amber and clear.

Females paler; vertical bars more prominent. Hue of pattern variable depending on state and condition of individual, water clarity, and background. All colours intensified in breeding males. Young with much less colour pattern and only green to olive background colour

History of Introduction and Spread

Top of page

The native distribution of L. gibbosus in North America is restricted to eastern North America, where sunfishes are known to have existed since the Miocene (Scott and Crossman, 1973). The species was introduced into European waters during the late nineteenth century, initially to the northwestern countries such as Belgium (Maes, 1898), France (Künstler, 1908), and Germany (Max von Borne, 1826–1894; cited in Freyhof, 2003) and then sometime during the period from 1890 to 1915 to the British Isles (Copp et al., 2002). Establishment in France was said to require repeated introductions (Künstler, 1908), but once established the rapid expansion of populations caused concern (Roule, 1928, 1935). Early established populations in the northern countries, such as England (Wheeler and Maitland, 1973), Scotland (Lever, 1977) and the low countries, went virtually unnoticed until recently (Copp et al., 2002; van Kleef et al., 2008; Cucherousset et al., 2009). Whereas in southern and central Europe, where L. gibbosus was introduced more widely during the second half of the twentieth century, the species attracted greater and earlier scientific interest due to its invasive character (Copp and Fox, 2007). L. gibbosus is now established in at least 28 countries of Europe and Asia Minor, with a few populations reported for South America (Brazil, Chile), and scientific interest in the species has intensified since the early 1990s (Copp and Fox, 2007).

Risk of Introduction

Top of page

The main introduction pathways for L. gibbosus have been varied, including use as an ornamental species in outdoor ponds on private estates (e.g. United Kingdom), sport fishing (e.g. France), or for extensive fish culture for use as forage food for largemouth bass (Iberia and Congo) and more recently as a pet fish, i.e. indoor aquaria (e.g. Norway). Human assistance in the spread of L. gibbosus (e.g. by anglers) appears to be more common in southern Europe than elsewhere, though it is rarely sought after in Europe as an angling amenity in its own right. L. gibbosus has also been reported in the Czech literature to have been imported into the former Czechoslovakia inadvertently with young carp (Tandon, 1976), and similar accidental introductions are believed responsible for the species’ spread amongst water bodies in southern England (Copp et al., 2004).

Habitat

Top of page

In its native range, L. gibbosus occurs and reproduces in both lakes, reservoirs and water courses (Copp and Fox, 2007), though the species is most commonly associated with lacustrine ecosystems. In its introduced range, the species is established almost exclusively in lacustrine ecosystems in northern Europe (Cucherousset et al., 2009), with no reproduction observed so far in English streams (Copp and Fox, 2007). Whereas in southern latitudes, in particular in Iberia, L. gibbosus populations establish easily in regulated rivers and reservoirs (Ferreira et al., 2007; Hermoso et al., 2008), but the species is less successful in natural streams, occurring in low abundance relative to native fish species (Clavero et al., 2004; Mesquita et al., 2006; Almeida et al., 2009a).

Biology and Ecology

Top of page

Genetics

Haploid/gametic (n) – 24. Diploid/zygotic (2n) – 48-48. L. gibbosus are known to hybridize in nature with the warmouth, and the red breast, green, orange spotted, bluegill, and longear sunfishes. Hybrid sunfishes are often fertile and can recross with other hybrids. The DNA of this species has extensively been sequenced, for example, for DNA bar-coding purposes (Hubert et al., 2008).
 
Reproductive Biology
 
Males build the nest on very shallow waters near the shore and attract a female. The pair then swims in a circular path over the nest, and eggs and sperm are released in intervals. The male guards the eggs and the young up to 11 days after hatching, though much shorter periods of care have been reported in Europe (Balon, 1959), then prepares the nest for another spawning with the same or different females. Females produce up to 1000 eggs.
 
Associations
 
L. gibbosus has been reported to be associated with first reports of non-native monogeneans in Norway (Sterud and Jørgensen, 2006) and England (E Sterud in Copp et al., 2010).
 
Environmental Requirements
 
L. gibbosus inhabits ponds, lakes and water courses over a wide latitudinal distribution in its native North American range (Scott and Crossman, 1973), and an equally diverse range of waters throughout its introduced European range (Copp and Fox, 2007), with at least a few introduced populations established in South America (de Magalhães and Ratton, 2005). In Spain, the species have been found to benefit from human disturbances to water courses (Almeida et al., 2009a). However, L. gibbosus populations in northern parts of Europe appear to reproduce in lacustrine environments only (Copp and Fox, 2007; Cucherousset et al., 2009).

Means of Movement and Dispersal

Top of page

Natural Dispersal (Non-Biotic)

L. gibbosus is known to disperse via natural drift in water courses (e.g. Copp and Cellot, 1988), from water bodies that discharge into water courses (Stakenas et al., 2008), and to move actively within water courses (Copp et al., 2010).
 
Vector Transmission (Biotic)
 
No reports of such transmission are available for L. gibbosus.
 
Intentional Introduction
 
L. gibbosus has been stocked into water bodies and water courses for ornamental and for angling purposes (e.g. initially as a sport fish [e.g. Künstler 1908] but later as a forage fish for piscivorous fishes).

Impact on Habitat

There is no information available regarding habitat impacts of L. gibbosus in its introduced range other than those based on supposition, though evidence from the Netherlands (van Kleef et al., 2008) may suggest impacts on pond shorelines where spawning activity is most intensive.

Impact on Biodiversity

The impact of L. gibbosus in Europe remains poorly assessed. The species has been reported to prey on fish eggs (García de Jalón et al., 1993; García-Berthou and Moreno-Amich, 2000a) as well as an endemic mollusc subspecies (García-Berthou and Moreno-Amich, 2000a), and it has been said to contribute to the decline of some indigenous fish species (Godinho and Ferreira, 1998). However, the only known study to document impacts of L. gibbosus on biodiversity comes from the Netherlands (van Kleef et al., 2008). A variety of studies on L. gibbosus in a stream system of southern England failed to demonstrate firm evidence of any adverse impact, though a stream reach containing high densities of the species was found to have a lower density and species diversity of riparian spiders, relative to stream reaches with few or no L. gibbosus, with two typical riparian spider species being absent (Copp et al., 2010). Recent work suggests that L. gibbosus is aggressive towards native Iberian species (Almeida et al., 2009b).

Social Impact

Top of page

L. gibbosus has long been considered a pest (Künstler, 1908; Roule 1928, 1935), but there is no documented evidence of the species having an adverse effect other than public perception.

Similarities to Other Species/Conditions

Top of page

L. gibbosus resembles the bluegill Lepomis macrochirus, which is another member of the Centrarchidae, though much less-widely introduced than L. gibbosus. It can be distinguished in many cases by the presence of a red spot on the operculum flap. This spot is often referred to as being scarlet or crimson, and very rarely is observed to be orange or even more rarely yellow.
