		The Acipenseriformes, a group included in the Chondrostei, are probably the most distinctive Recent order of the Actinopterygii.
		The cartilaginous skeleton of the acipenseriform fishes was long regarded as primitive, and was taken as indicative of alliance with the Chondrichthyes.
		Research reveals, however, that this is secondary, and the true relationship is with typical bony fishes.

	Endangered Fish
		The Siberian sturgeon (subspecies baerri) is classified as a member of the order Acipenseriformes and is a member of the family Acipenseridae.
		It is classified as an endangered species due to a projected reduction of at least 50% of the Siberian sturgeon population over the next ten years based on actual levels of exploitation.
		It is classified as a critically endangered species due to a projected reduction of at least 80% of the Alabama sturgeon population over the next ten years based on levels of exploitation and a decline in area of occupancy.

		This collection of literature dealing with all species and various topics related to Acipenseriformes is intended to serve as a ready reference for researchers, fisheries managers, aquaculturists and conservationists who work with this ancient fish group.
		This volume presents a synthesis of basic biological and conservation data for all species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes.
		Recent evidence from fossil Acipenseriformes strongly supports a sister-group relationship of Acipenseridae and Polyodontidae as the suborder Acipenseroidei.

	ABL - Hearing in Primitive Fish
		Sturgeon belong to the order Acipenseriformes which together with the Polypteriformes (bichir and reedfishes) form the group “lower Actinopterygian fishes”.
		It is assumed that the Acipenseriformes separated from the “advanced fishes” in the Triassic, about 200 million years ago.
		Because of their diversity and phylogenetic position as a basal group within Actinopterygians, Acipenseriformes are considered to be essential for comparative studies within extant and fossil Actiopterygians in the evolutionary literature.

	Genome size and longevity are not correlated in fishes
		His criticism of the fact that the significant positive correlation between mass-corrected longevity and genome size within the order Acipenseriformes could be biased due to polyploidy is relevant and deserves consideration.
		I wasn't arguing that the difference in DNA content between sturgeons and teleosts was due entirely to polyploidy in the former (although this is a definite concern).
		Rather, the point is that finding significant correlations within the Acipenseriformes (which is the only place they found one) is problematic, because here the differences in DNA content are most likely due to polyploidy.

		Despite the CITES listing, beluga sturgeon populations have continued to decline, and the population structure is increasingly skewed towards sub-adult fish, with a critical lack of spawning-age adult female fish.
		The family Acipenseriformes encompasses all species of sturgeon and paddlefish, the caviar-producing fishes considered the most economically valuable fish in the world.
		In an assessment by TRAFFIC (1999), the state of all Russian sturgeon populations was considered ``catastrophic.'' International conservation measures were taken in 1998 to address escalating concerns regarding the status of Caspian Sea sturgeon.

	Purification and cardiovascular activity of [ Met1, Met5]-bradykinin from the plasma of a sturgeon (Acipenseriformes). (Site not responding. Last check: 2007-10-26)
		Purification and cardiovascular activity of [ Met1, Met5]-bradykinin from the plasma of a sturgeon (Acipenseriformes).
		Thus, the cardiovascular response of the sturgeon to bradykinin resembles more closely the response of mammals rather than the predominantly pressor response seen in teleost fish.
		The sturgeons (Order Acipenseriformes) are extant representatives of a group of primitive Actinopterygian (ray-finned) fish that probably shared a common ancestor with present-day teleosts.

	Palaeos Vertebrates 90.300 Teleostomi: Actinopteri
		By the mid-twentieth century, the Chondrostei had become a garbage taxon full of "paleonisciform" fish of uncertain affinities.
		Bemis and Grande use the name "Chondrostei" rarely, preferring the less ambiguous "Acipenseriformes." However, there is still some utility in a stem taxon defined as fish more closely related to caviar (Huso) than to lox (Salmo), and it is in that sense that "Chondrostei" is used here.

		In order to prevent further decline of sturgeon resources, the whole Acipenseriformes order was placed under the species protection system of the CITES Convention in 1997.
		Roe coming from a fish other than Acipenseriformes is not caviar, and is often classified as “caviar substitute”.
		In 2001, the catch and export quotas for shared stocks of Acipenseriformes included in the Review of Significant Trade, such as the Caspian Sea stocks, were the result of an agreement between the CITES Standing Committee and the range states.
