Pool-type fishways have been increasingly tested to improve fish passage performance and minimize migration delays. Designing cost-effective is essential for a trade-off between water uses successful longitudinal connectivity restoration. The multislot fishway (MSF) concept, which operates with 30–50% lower discharge than vertical slot (VSF), was recently developed. This study assessed compared...

The genetic structure of the genus Alburnus is not well known and the phylogenetic relationships among its species are uncertain. In the present study, simple sequence repeats (SSRs or microsatellites) were used to evaluate genetic diversity and genetic differentiation between Alburnus mossulensis Heckel, 1843 from Kashgan River in Lorestan province and Alburnus caeruleus Heckel, 1843 from Gama...

Goldfish are among a group of fishes which possess a highly developed sense of taste. Many species of the cyprinid (minnow) and catostomid (sucker) families possess specialized food-handling structures in the oropharynx (e.g. the palatal organ and branchial arches) which are covered with taste buds innervated by fibers of the glossopharyngeal and vagal nerves. The central termination for these ...

A field isolate of pike fry rhabdovirus (PFR-80560) isolated from roach was tested for pathogenicity in fry of roach Rutilus rutilus L., common carp Cyprinus carpio L., grass carp Ctenopharyngodon idella Valenciennes and rainbow trout Oncorhynchus mykiss Richardson. The fish were experimentally exposed to the virus by immersion in a virus-seeded water-bath. We also compared the pathogenicity of...

The architecture of the MHC in teleost fish, which display a lack of linkage between class I and II genes, differs from all other vertebrates. Because rainbow trout have been examined for a variety of immunologically relevant genes, they present a good teleost model for examining both the expression and organization of MHC-related genes. Full-length cDNA and partial gDNA clones for proteasome d...
