Copeia, 1994 We examined the reproductive traits and early survival of ayu, Plecoglossus altivelis (Osmeridae), from amphidromous and land-locked populations under controlled rearing conditions to evaluate the adaptive significance of egg size variation. Spawning was earlier for land-locked than for amphidromous ayu and was earlier for larger individuals within a ...

Relationships among the species of Northern Hemisphere smelts (family Osmeridae) have long been debated in the fish systematics literature. Eight independent studies based on morphological characters failed to reach any consensus on osmerid interrelationships.

Aquatic Toxicology, 2011 The delta smelt (Hypomesus transpacificus) is an endangered pelagic fish species endemic to the Sacramento-San Joaquin Estuary in Northern California, which acts as an indicator of ecosystem health in its habitat range. Interrogative tools are required to successfully monitor effects of contaminants upon the delta smelt, and to research potential ...

Reproductive Biology of Rainbow Smelt Osmerus dentex (Osmeridae) of the Amur River
Journal of Ichthyology, 2020Spawning flocks of rainbow smelt Osmerus dentex, in an anadromous migration in the Amur River were represented by individuals of length 15–25 cm at ages 3–5, among which males predominated (1 : 2). Histologic analysis shows that rainbow smelt is an iteroparous species with determinate fecundity, group-synchronous ovary organization and total spawning ...

Molecular cloning and characterization of rhodopsin in a teleost (Plecoglossus altivelis, Osmeridae)
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2003Amplified fragments encoding exon-4 of opsin cDNAs were cloned from the retina of landlocked ayu (Plecoglossus altivelis), and sequenced. On the basis of the sequence homology to previously characterized fish visual pigments, one clone was identified as rod opsin (AYU-Rh), and two clones as green (AYU-G1, -G2), one as red (AYU-R) and two as ultraviolet
