Crenicichla gillmorlisi, new species, is described from the río Acaray, a right bank tributary to the río Paraná. It is most similar to C. mandelburgeri in proportional measurements and meristics, but differs in colour pattern, adults having the body covered with small spots.

The fish species Symphodus bailloni (Valenciennes, 1839) reported in the present study were collected between June 2010 and June 2011 from the western Black Sea coasts which were previously not recorded from the Black Sea coast of Turkey. A total of 717 specimens of S. bailloni were measured, ranging between 8.9 and 15.4 cm TL. Morphometrics, meristics, and diagnostic characteristics of the spe...

Four species of Devario are recorded from Bangladesh: D. aequipinnatus, D. anomalus, D. coxi, new species, and D. devario. Devario aequipinnatus has a wide distribution in northern India and Bangladesh. Devario coxi, from southeastern Bangladesh near Cox's Bazar, differs from D. aequipinnatus in mtDNA (COI, p-distance 1.8%), colouration, proportional measurements, and meristics. The minor morph...

as a result of our survey in february 2011, a single female specimen of n. dipterygia was found in the tidal zone of chabahar bay and it was caught with a small deep net. the fish was transferred in a bucket to the fisheries laboratory of chabahar maritime university and kept in a salt water aquarium for further examinations. we witnessed the birth of 6 juveniles after 3 days. the female and he...

A new shovelnose ray, Rhinobatos whitei sp. nov., is described from material collected at fish markets of the southern Philippines. This ray was first formally indentified as an undescribed species more than a decade ago as part of a WWF funded survey of sharks and rays of the Philippines. It was considered to be most closely related to another shovelnose ray found nearby in the western North P...

The eagle rays Myliobatis hamlyni Ogilby, 1911 and Myliobatis tobijei Bleeker, 1854 are redescribed based on museum specimens and new material from Australia, Indonesia, the Philippines, Taiwan and Japan. These two species are closely related to Myliobatis aquila (L.) from the eastern Atlantic and can be distinguished from each other by a combination of their coloration, meristics, depth prefer...

in this study 485 specimen of garra rufa (heckel, 1843) from 29 populations from six river systems and basins including tigris, karkheh, karun, persis (helleh and mond), hormuz and maharlu were collected by a 5mm mesh sized seine net, anesthetized in 1% clove oil solution, fixed in 10% formalin and transferred to the laboratory for further investigations. some 28 morphometric, 25 morphometric p...

Blunthead puffer Sphoeroides pachygaster (Müller and Troschel, 1848) is a circumglobally distributed Tetraodontid found in temperate tropical waters. It believed to have colonized the Mediterranean Sea from Atlantic Ocean. There are relatively few records of this fish Sea. On March 2020, mature female individual was caught incidentally by commercial fisher Northern Cyprus. The 520 mm total leng...

Paragaleus tengi was previously considered to be the only member of this genus occurring in the Western Pacific, with Paragaleus randalli occurring in the Indian Ocean and allopatric in distribution. Recent molecular and morphological studies showed that P. randalli also occurs in the Western Pacific with records from Thailand, Malaysia and Indonesia previously mostly incorrectly attributed to ...

A new long-snouted skate, Dipturus amphispinus sp. nov., is formally described based on material caught in the Sulu Sea and later acquired from fish markets of the central and southern Philippines. It differs from its congeners in the western North Pacific, apart from D. wuhanlingi (East and South China Seas), in having a variably-defined, parallel row of posterolaterally directed lumbar thorns...
