Abstract Fish species are being described at an accelerating rate, but a substantial fraction of recent descriptions rests on evidentiary standards too weak to distinguish genuine species‐level discontinuities from intraspecific variation, local adaptation and the artefacts of single‐marker analyses, a pattern of taxonomic inflation with documented ...

Evolution of MHC class I genes in two ancient fish, paddlefish (Polyodon spathula) and Chinese sturgeon (Acipenser sinensis) [PDF]
Here we present the first isolation of major histocompatibility complex (MHC) class I genes from two ancient fish, paddlefish (Polyodon spathula) and Chinese sturgeon (Acipenser sinensis).

Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Nitrogenous compounds and oxygen concentration as the key density dependent factors to optimize growth of beluga, Huso huso (Actinopterygii: Acipenseriformes: Acipenseridae), in circular fiberglass tanks [PDF]
Background. Beluga, Huso huso, known also as the great sturgeon, is a valuable fish in terms of meat and caviar production. It has been implicated that intensive fish culture is a major culprit for deterioration of water quality through metabolic ...

In this case, the hierarchical win is 1/2 + 1/4 + 1/8 = 7/8, as “acipenseriformes,” “sturgeon,” and “acipenser” are the nodes on both the path from the root “acipenseriformes” to “acipenser (oxyrinchus)” and the path from the root “acipenseriformes” to ...

In this case, the hierarchical win is 1/2 + 1/4 = 3/4, as “acipenseriformes” and “sturgeon” are the nodes on both the path from the root “acipenseriformes” to “acipenser (oxyrinchus)” and the path from the root “acipenseriformes” to “huso”.
