A new species of copepod, Colobomatus stelliferi n. sp., belonging to the cyclopoid family Philichthyidae Vogt, 1877 is proposed based on female specimens collected from the mandibular canals of three species of sciaenid teleosts: Stellifer brasiliensis (Schultz) (type-host), S. rastrifer (Jordan) and S. stellifer (Bloch), collected in Caraguatatuba Bay, State of São Paulo, Brazil. The new spec...

The Redeye Bass, Micropterus coosae, was described from the Mobile River basin, Chattahoochee, and Savannah rivers in Alabama and Georgia, USA, by Hubbs and Bailey (1940). At that time the authors recognized significant variation in the Black Warrior River population, and noted that with further study this form may be recognized as a separate taxon. An examination of variation in morphology and...

We describe a new species of the genus Crenicichla Heckel, 1840, from the Ventuari River, a tributary of the Orinoco River in southern Venezuela. Crenicichla zebrina is distinguished from all other species in the genus by its unique coloration pattern, including the combination of a large, dark, vertically oriented, more or less oval-shaped humeral spot, and thin, dark bars, separated by narrow...

A morphological and genetic reassessment of the phylogeny and taxonomy of the dwarf zoarcid fish Lycodes teraoi Katayama, 1943 indicated that the species, a senior synonym of Lycodes sadoensis Toyoshima & Honma, 1980, should be placed in the genus Petroschmidtia. A redescription of P. teraoi is provided, with remarks on its taxonomy. Numerous specimens revealed a wide distribution of P. teraoi ...

A new species, Prosorhynchus maternus sp. n., is described from the serranid fish Epinephelus malabaricus (Bloch et Schneider) in the waters off New Caledonia. It belongs to a group of Prosorhynchus species from serranids in which the uterus is restricted to the postovarian region. Its distinguishing features include the vitellarium relatively distant from the rhynchus, the cirrus-sac relativel...

Phylogenetic relastionships within the family pomacentridae teleostei: Perciformes) were inferred by analyzing a portion of the 12S mitochondrial ribosomal DNA gene. Thirty-four pomacentrid species were sequenced for this study and the resulting data were combined with previously published pomacentrid sequence data to form a combined matrix of 53 pomacentrids representing 48 different species i...

Understanding the distributional patterns of individual animal groups with respect to coastal topology and the local physical environment provides essential foundational frameworks for marine zoogeography. In the northwestern Pacific waters of Japan, the distributional pattern of some cool-temperate species of marine fishes suggests the existence of a biogeographic boundary corresponding to a l...

The impact of a fish sanctuary on fisheries diversity was studied for two years in Chalan Beel, Tarash Upazila, Sirajganj district, where the established at end first year. Seine net (Berjal) used to collect data monthly basis. There were 42 species recorded from 8 orders and 18 families, including exotic species, Cyprinus carpiro Oreochromis mossambicus. Puntius puntio most common (18.38%), fo...
