The effect of short-term starvation on some physiological and morphological parameters in juvenile Siberian sturgeon, Acipenser baerii (Actinopterygii: Acipenseriformes: Acipenseridae) [PDF]
Acta Ichthyologica et Piscatoria, 2013 Background. Fish may experience periods of food deprivation or starvation in nature and under culture conditions. Because of the wild  stock reduction of some sturgeon species, Siberian sturgeon, Acipenser baerii Brandt, 1869, has been used as a

Efficient Gene Transfer and Gene Editing in Sterlet (Acipenser ruthenus)
Frontiers in Genetics, 2018 The sturgeon (Acipenseriformes) is an important farmed species because of its economical value. However, neither gene transfer nor gene editing techniques have been established in sturgeon for molecular breeding and gene functional study until now.

Early evolution of the gular musculature and its innervation in ray‐finned fishes
The Anatomical Record, EarlyView.Abstract Gular muscles are an important but often overlooked component of cranial anatomy in bony fishes. They are located on the ventral surface of the head and are derived from the mandibular and hyoid arches. We present a comprehensive review of the gular musculature and its innervation across early diverging actinopterygian lineages. By integrating

Developmental Dynamics, EarlyView.Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Journal of Fish Biology, EarlyView.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 ...
