Biology ( Inglês )

fornecido por Fishbase
Lives in streams, backwaters, lakes, swamps and estuaries. Occurs in brackish estuaries and inland salt lakes. Most common in slow-flowing streams and still waters, shoaling near the surface or around the cover of aquatic plants and woody debris. Forms large aggregations in open water (Ref. 44894). Feeds on aquatic insects, microcrustaceans and algae. Spawns throughout the Murray-Darling river system. Breeds between July and March (mostly in spring) (Ref. 44894). Spawning temperature is about 15 °C. Newly hatched larvae measure 4.8 mm TL on the average. Eggs are laid among aquatic vegetation and hatch in about 10 days. Sexual maturity is attained by the end of the first year (Ref. 44894). Eaten fresh or canned.

Australian smelt ( Inglês )

fornecido por wikipedia EN

The Australian smelt (Retropinna semoni) is a small, pelagic silvery freshwater fish found in large numbers in waters of the south eastern Australian mainland.

Distribution

The fish is endemic to Australia and widely distributed through the coastal drainages of the south eastern part of the mainland.[2] The species is found in coastal drainages from the south east corner of South Australia through Victoria, New South Wales to the Fitzroy River in south east Queensland. It occurs widely in the Murray River and its tributaries and up the Darling as far upstream as Wilcannia. There are isolated populations in the Coopers Creek which drains into Lake Eyre and several smaller ones in north-western New South Wales and southern Queensland. Recent genetic research indicates Australian smelt stocks are composed of 5 highly genetically distinct and as yet undescribed species (Hammer et al., 2007).

Description

A small silvery fish to 75 mm total length, very occasionally to 100 mm. In Coopers Creek usually only to 50 mm. It is clear to purple-olive on the back, translucent with a silver streak along the sides, sometimes with orange highlights, and has colourless fins. Captively raised specimens will easily exceed 100mm[3] and live for longer periods than their wild counterparts.[2]

Habitat

Often found in large schools of thousands, this pelagic species prefers slow moving or still waters. It is often found in billabongs, dams and lakes at various salinity levels and in the lower reaches of rivers and streams. Although there have been some reports of diadromous populations, this fish usually completes its entire life cycle in freshwater. They shoal near the surface and around the cover of aquatic plants and woody debris.[2]

Diet

A carnivorous fish, the Australian smelt feeds mostly on small invertebrates such as aquatic insects and microcrustaceans, and a variety of planktonic organisms.

Reproduction

Spawns in spring at water temperatures in excess of 15 °C. Eggs are demersal, adhesive, spherical and transparent, about 0.8 mm diameter to 1 mm when water hardened. Eggs fall to the bottom and stick to instream debris, vegetation and the substrate. Females lay between 100 and 1000 eggs. Hatching occurs at about 9 to 10 days and larvae are around 4.5 to 5 mm total length.

Importance to humans

This species has some potential as an aquarium species. Ideally suited to use as an effective mosquito predator in ponds in south eastern Australia, especially where frogs are encountered. Not suitable for use in a community tank, best kept as a school of fish in a single species situation.

Retropinna semoni ( Francês )

fornecido por wikipedia FR

Retropinna semoni (l'Éperlan australien) est une espèce de poissons qui se rencontre dans un grand nombre de rivières du sud-est de l'Australie.

Description

C'est un petit poisson argenté de 7,5 cm de long en moyenne, 10 cm pour les plus grands.

Distribution

Poisson très abondant dans tout le sud-est du continent australien, on le trouve dans toutes les rivières côtières d'Australie-Méridionale, de l'État de Victoria et de Nouvelle-Galles du Sud, jusqu'à la rivière Fitzroy au sud-est du Queensland. Il est très abondant dans le Murray et ses affluents notamment la Darling jusqu'à Wilcannia. On trouve des populations isolées dans la rivière Coopers qui se jette dans le lac Eyre et quelques individus de petite taille au nord-ouest de la Nouvelle Galles du Sud et au sud du Queensland.

Alimentation

Il se nourrit de petits insectes aquatiques, de tout petits crustacés et de plancton.

Mode de vie

Il vit souvent en grands bancs, dans les eaux stagnantes ou calmes. On les trouve souvent dans les billabongs, les barrages, les lacs australiens plus ou moins salés et dans la partie basse des cours d'eau. Bien qu'on ait signalé quelques populations diadromes, ces poissons vivent généralement uniquement en eau douce.

Reproduction

Il se reproduit au printemps dans des eaux de température supérieure à 15 °C. La femelle pond entre 100 et 1 000 œufs qui sont fécondés par le mâle. Les œufs transparents, sphériques, de 0,8 à 1 mm de diamètre rassemblés en grappes vont tomber sur le fond et s'accrocher à la végétation, des débris ou sur le sol. Les alevins naissent 9 à 10 jours après la ponte et mesurent 4,5 à 5 mm de long.

Intérêt

Pouvant être utilisé comme poisson d'aquarium pour sa couleur argentée, il est surtout utilisé dans les mares et autres étendues d'eau douce car se nourrissant de larves de moustiques, il permet une démoustification efficace et peu onéreuse.
