A novel sperm adaptation to evolutionary constraints on reproduction: Pre‐ejaculatory sperm activation in the beach spawning capelin (Osmeridae) [PDF]
AbstractReproduction of external fertilizing vertebrates is typically constrained to either fresh or salt water, not both. For all studied amphibians and fishes, this constraint includes immotile sperm that are activated after ejaculation only by the specific chemistry of the fertilizing medium in which the species evolved (fresh, brackish, or salt ...

Complete mitochondrial genome of the European smeltOsmerus eperlanus(Osmeriformes, Osmeridae) [PDF]
The complete mitochondrial (mt) genome was sequenced in two individuals of the European smelt Osmerus eperlanus. The genome sequences are 16,608 and 16,609 bp in size, and the gene arrangement, composition, and size are very similar to the other smelt mt genomes previously published. The difference between the two genomes studied is low, 0.05%.

The complete mitochondrial genome ofHypomesus olidus(Osmeriformes: Osmeridae) [PDF]
Pond smelt Hypomesus olidus is a small-sized economic species of freshwater fish with delicious meat and high output. In this study, the complete mitochondrial genome of H. olidus sequenced to be 16,786 bp in length, including 13 protein-coding genes, 2 ribosomal RNAs, 22 transfer RNAs and a control region. The overall base composition of H.

Complete mitochondrial genome of the surf smelt Hypomesus japonicus (Osmeriformes, Osmeridae) [PDF]
The complete mitochondrial genome was sequenced in two individuals of the surf smelt Hypomesus japonicus. The genome sequences are 16,762 and 16,771 bp in size, and the gene arrangement, composition, and size are very similar to the other smelt mitochondrial genomes published previously. The difference between two H. japonicus genomes studied is 0.37%,

Temperature and salinity preferences of endangered Delta Smelt (Hypomesus transpacificus, Actinopterygii, Osmeridae) [PDF]
AbstractTemperature and salinity often define the distributions of aquatic organisms. This is at least partially true for Delta Smelt, an imperiled species endemic to the upper San Francisco Estuary. While much is known about the tolerances and distribution of Delta Smelt in relation to these parameters, little is known regarding the temperature and ...

First cytogenetic characterization of the sub-arctic marine fish Mallotus villosus (Müller, 1776), Osmeriformes, Osmeridae [PDF]
The capelin, Mallotus villosus (Osmeriformes, Osmeridae), is an ecological and commercial key component of the sub-arctic ichthyofauna. Here, we provide the first cytogenetic information on the species based on both conventional karyotyping and chromosomal mapping of 45S and 5S ribosomal genes through fluorescence in situ hybridization (FISH).

Morphological Variability of the Smelts (Osmeriformes: Osmeridae) of the Russian Far East
This paper presents the first study comparing the smallmouth smelts – the Japanese smelt Hypomesus nipponensis McAllister, 1963, the pond smelt H. olidus (Pallas, 1814), the marine smelt H. japonicus (Brevoort, 1856) – and the Asiatic smelt Osmerus dentex Steindachner et Kner, 1870 with the use of the variance of fluctuating asymmetry, the coefficient ...

Photoreceptors, visual pigments and intraretinal variability in spectral sensitivity in two species of smelts (Pisces, Osmeridae) [PDF]
AbstractThe main goal of this study was to clarify whether the spectral properties of retinal photoreceptors reflect the features of behaviour of closely related fish species cohabiting shallow marine and fresh waters. The spectral sensitivity of photoreceptors was compared between two smelt species, Hypomesus japonicus and Japanese smelt Hypomesus ...
