Family - Cobitidae A large family native to Europe and Asia, with its greatest diversity in southern Asia and the Malay Archipelago. Australia has no native cobitids, however one species has recently become established in south-eastern Australia. Oriental weatherloach Misgurnus anguillicaudatus (Cantor) (R.H.Kuiter) Other names: Japanese weatherloach, Japanese loach, Loach, Mud loach, Weatherfish. Description: Elongated cylindrical body. Single short-based dorsal fin (5-7); anal fin (5-6) short based and rounded. (9-10) Pectoral fins; pelvic fins (5-8). Rounded tail; five pairs of conspicuous barbels around mouth. Body covered in mucus. Maximum length of about 250 mm but in Australia usually 200 mm or less. Distribution: The first recording of feral populations in Australia was in the Yarra River, Victoria. A population now occupies a substantial portion of the Ovens River and Murry River downstream to at least Barmah Forest. There are at least three other recorded weatherloach populations in the Melbourne Metropolitan area. There have been recent records from the Latrobe River. A population from the Australian Capital Territory spread into New South Wales waters including the Murrumbidgee River down to lake Burrinjuck. Colonies from the Wingecarribee River have now reached into Lake Burragorang and Coxs River. In late 1992 they were discovered in a small tributary of Lake Eucumbene in the Snowy Mountains in New South Wales. they have also become established in a small suburban creek near Brisbane. There are unconfirmed reports in South Australia and Western Australia. Alien Fishes | Family Cobitidae | Page 1 Natural History: This species is a prised aquarium fish with a native Eurasian distribution. First reports of its establishment in the wild in Australia were in 1984. Weatherloach were probably released into these waterways following the release of unwanted aquarium fish.

First Fossil Cobitid (Teleostei: Cypriniformes)
第53卷第4期古脊椎动物学报 pp. 299-309 2015年10月 VERTEBRATA PALASIATICA figs. 1-3 First fossil cobitid (Teleostei: Cypriniformes) from Early- Middle Oligocene deposits of South China CHEN Geng-Jiao1,2 LIAO Wei1 LEI Xue-Qiang1 (1 Natural History Museum of Guangxi Zhuang Autonomous Region Nanning 530012 [email protected]) (2 State Key Laboratory of Palaeobiology and Stratigraphy (Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences) Nanjing 210008) Abstract †Cobitis nanningensis sp. nov., the earliest fossil cobitid fish from Early-Middle Oligocene deposits of Nanning Basin, Guangxi Zhuang Autonomous Region, southern China, is described here. The new species is represented by specimens of the distinctive suborbital spine. The bifid suborbital spines are 1.8−3.0 mm in length. Their laterocaudal processes are thinner and shorter than their mediocaudal processes, and the lengths of the laterocaudal processes are about 1/3 of those of the mediocaudal ones. The lateral process of the spine is prominent. The new species most closely resembles †Cobitis primigenus from the Late Oligocene deposits of Germany, but in †C. nanningensis the lateral process of the suborbital spine is more developed. The discovery of the new species and other previously known fossils of Cobitis indicate that the Cobitidae family has had a wide distribution in Eurasia since at least Oligocene. Key words Nanning Basin, Guangxi; Early-Middle Oligocene; Cypriniformes, Cobitidae, suborbital spine Nanning Basin is a Paleogene inland faulted basin situated in the southern part of Guangxi Zhuang Autonomous Region, South China. Since the first investigation by Zhu Tinghu in 1920s in this basin, many Eocene and Oligocene fossils of invertebrates (e.g.

Parallel to genetic studies, morphological examinations are needed for further development of loach study, eventually ichthyology and ﬁsh biology. Digital archiving, concerning taxonomy, ecology, ethology etc., is one of the progressive challenges for the open science of biology. This paper aimed to online publish photo images, 3D models and CT scanned data of all the known clades of loaches inhabiting Japan (103 individuals in total with several type specimens), contributing to ichthyology and public interest of biodiversity/biology. © Kano Y et al.

The family has 12 radiated over Asia. For some species their range is limited to single catchments; they provide an ex- 13 cellent example of biogeographical speciation on multiple scales. Hill stream loaches have a range of 14 adaptations which help them exploit environments where competitors and predators would be 15 washed away. They have streamlined bodies and keeled scales reminiscent of Mako sharks and po- 16 tentially many other as yet undiscovered drag reducing features. They adhere to rocks, crawl over 17 shallow films of water, glide over hard surfaces using ground effects and launch into currents to at- 18 tack prey or evade predation. They offer a test of modern approaches to organismal biology and a 19 broad range of biomimetic potential. In this paper we analyse what behaviour is associated with 20 their physical adaptations and how this might relate to their evolution and radiation.

Perikanan No. 13, Depok 41152, Indonesia Received 10 January 2012; Accepted 23 April 2012 Abstract – The clown loach Chromobotia macracanthus, endemic to Indonesia, is a major species on the international market of ornamental freshwater fish. In order to satisfy an increasing demand with a sustainable alternative to the massive capture of wild juveniles, research has been dedicated to the artificial propagation and domestication of this species. The present study, the first of a series, focused on favourable maintenance conditions for broodfish sexual mat- uration, criteria for identification of ripe fish, efficiency of hormone-induced breeding treatments, predictability of their latency response, and on the comparison of reproductive performances of fish from populations of Sumatra and Borneo Islands (in total, 112 females of 46 to 404 g body weight). When reared in fully controlled conditions in large water recirculation systems, broodfish originating from Sumatra had reproductive performances similar to or slightly higher than those maturing in the wild (ovulation rate of 93% vs.

Spawning Method: Egg-layer Corydoras (AKA cory cats and cories) are very hardy and make good beginner fish for a community tank. For species tank, the dwarf cories do better. There are generally 2 types of cory, the dwarf cory and the normal cory. Brochis are not cories. The dwarf cory is great for nano tanks because it usually remains less than 3cm long ( about 1.3 inch). They do well in community tanks too and the only special care they require is not putting them together with aggressive fish like Cichlids. Dwarf Cichlids may do well with them occasionally but avoid them if you can.

Investigation Food Diet of Cobitis Taenia in Talar River (Mazandaran Province)
Journal of Food Science and Engineering 2 (2012) 697-704 D DAVID PUBLISHING Investigation Food Diet of Cobitis taenia in Talar River (Mazandaran Province) Soheil Bahrebar Iranian National Institute for Oceanography, Tehran 1411813389, Iran Received: August 8, 2012 / Published: December 20, 2012. Abstract: Perch sweeper fish with scientific name Cobitis taenia is one of the Cobitidae family. Since this kind of fish lives in clean waters and in the high areas of Talar River, it can be an index on water implution. This survey on the diet of this specimen is done on two stations (Kaselian and Tajoon) and shallow and high areas of Talar River in Mazandaran (Southern part of Caspian sea) and the duration of this survey is from October 2008 till September 2009. We should mention that fishing was just done by electro-shocker with voltage 300 V. And this fish after fishing is fixation in 10% formalin solution. So 410 perch sweeper fish were examined and the average of relatively length of gut (RLG) was 17.35 cm. The index of vacated intestine (VI) was calculated 43.35% for all samples. From intense of diet points of view (GSI), the most frequency of full intestines was considered in summer and spring. On the other hand, the smallness of relatively length of gut index (RLG < 1) shows that perch sweeper fish’s diet manner is inclined to herbivority. In the examination of containing of digestive track, overally 10 kinds of foodstuff were known. Based on amount of this index, 2.67% Chironomidae is known as main bait in all sampling period.

SULAIMAN1 & R.L MAYDEN2 1Biological Science Programme, Faculty of Science, Universiti Brunei Darussalam, Tungku BE1410, Brunei Darussalam; E-mail:[email protected] 2Department of Biology, 3507 Laclede Ave, Saint Louis University, St Louis, Missouri 63103, USA; E-mail:[email protected] Abstract Borneo Island is governed by the countries of Brunei Darussalam, Malaysia (Sabah and Sarawak) and Indonesia (Kalimantan) and is part of Sundaland. These countries have a high diversity of freshwater fishes, especially described and undescribed species of Cypriniformes; together these species and other flora and fauna represent an extraordinary opportunity for worldwide collaboration to investigate the biodiversity, conservation, management and evolution of Borneo’s wildlife. Much of the fauna and flora of Borneo is under significant threat, warranting an immediate and swift international collaboration to rapidly inventory, describe, and conserve the diversity. The Sunda drainage appears to have been an important evolutionary centre for many fish groups, including cypriniforms (Cyprinidae, Balitoridae and Gyrinocheilidae); however, Northwestern Borneo (Brunei, Sabah and Sarawak) is not connected to Sundaland, and this disjunction likely explains the non-homogeneity of Bornean ichthyofauna. A previous study confirmed that northern Borneo, eastern Borneo and Sarawak shared a similar ichthyofauna, findings that support the general hypothesis for freshwater connections at one time between western Borneo and central Sumatra, and south Borneo and Java island.

According to the information provided by European Member States in the framework of the European Directive 92/43/EEC (Habitat Directive), the main threat to these ecosystems is represented by morphological and hydrological changes. The present work focuses on six lagoon fish species included in the Habitat Directive annex II (species requiring conservation measures: Aphanius fasciatus, A. iberus, Knipowitschia panizzae, Ninnigobius canestrinii, Valencia hispanica and V. letourneuxi) that spend their entire life cycle in the Mediterranean priority habitat 1150* “Coastal lagoons”. The overview of the current scientific literature allowed us to highlight how the presence and abundance of these species may provide important indications on the conservation status of coastal lagoon habitats. In fact, their occurrence, distribution and biology depend on the presence of peculiar structures, such as salt marshes, small channels, isolated pools and oligohaline areas. Coastal lagoon fragmentation and habitat loss have led to a significant reduction in genetic diversity or local population extinction.

COURTENAY, „ Aquatic Organisms f Introduced into North America SMITHSONIAN CONTRIBUTIONS TO ZOOLOGY • 1970 NUMBER 59 SERIAL PUBLICATIONS OF THE SMITHSONIAN INSTITUTION The emphasis upon publications as a means of diffusing knowledge was expressed by the first Secretary of the Smithsonian Institution. In his formal plan for the Insti- tution, Joseph Henry articulated a program that included the following statement: "It is proposed to publish a series of reports, giving an account of the new discoveries in science, and of the changes made from year to year in all branches of knowledge." This keynote of basic research has been adhered to over the years in the issuance of thousands of titles in serial publications under the Smithsonian imprint, com- mencing with Smithsonian Contributions to Knowledge in 1848 and continuing with the following active series: Smithsonian Annals of Flight Smithsonian Contributions to Anthropology Smithsonian Contributions to Astrophysics Smithsonian Contributions to Botany Smithsonian Contributions to the Earth Sciences Smithsonian Contributions to Paleobiology Smithsonian Contributions to Zoology Smithsonian Studies in History and Technology In these series, the Institution publishes original articles and monographs dealing with the research and collections of its several museums and offices and of professional colleagues at other institutions of learning. These papers report newly acquired facts, synoptic interpretations of data, or original theory in specialized fields. These pub- lications are distributed by mailing lists to libraries, laboratories, and other interested institutions and specialists throughout the world. Individual copies may be obtained from the Smithsonian Institution Press as long as stocks are available.
