You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 34.205.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:44, 30 September 2026.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

The '''starry sturgeon''' (''Acipenser stellatus'') also known as '''stellate sturgeon''' or '''sevruga''' (Drakul, ((Lang-fa|اوزون برون)),  and ((lang-tr|Uzun Burun|lit=long nosed))), is a species of [[sturgeon]]. It is native to the [[Black Sea|Black]], [[Sea of Azov|Azov]], [[Caspian Sea|Caspian]] and [[Aegean Sea|Aegean]] sea basins, but it has been [[Local extinction|extirpated]] from the last and it is predicted that the remaining natural population will follow soon due to [[overfishing]].<ref name="iucn status 18 November 2021" />

The starry sturgeon is an [[anadromous]] species, which migrates up rivers to spawn.<ref name="fishbase">((FishBase|genus=Acipenser|species=stellatus|month=February|year=2013))</ref>

It is considered [[critically endangered]] by the [[IUCN]] and international trade in this species (including [[Sevruga caviar|its caviar]]) is restricted by [[CITES]].<ref name="iucn status 18 November 2021" />

==Description==
The starry sturgeon reaches about ((convert|220|cm|ft|abbr=on)) in length and weighs up to ((convert|80|kg|abbr=on)).<ref name=fishbase/> It is a slim-bodied fish easily distinguished from other sturgeons by its long, thin and straight snout. A row of five small [[Barbel (anatomy)|barbels]] lies closer to the mouth than to the tip of the snout. The scales on the [[lateral line]] number between thirty and forty and these features distinguish this fish from the [[Russian sturgeon]] (''Acipenser gueldenstaedtii''). Its general colouring is dark greyish-green or brown with a pale underside. The scales on the lateral line are pale.<ref name=NatureGate>((cite web |url=http://www.luontoportti.com/suomi/en/kalat/stellate-sturgeon |title=Stellate sturgeon: ''Acipenser stellatus'' (Pallas) |publisher=NatureGate |accessdate=2013-12-25))</ref> The maximum reported age for this species is 27 years.<ref name=fishbase/>

==Biology==
The starry sturgeon is a harmless species that feeds on fish, worms, [[crustacean]]s and [[mollusks]].<ref name=fishbase/> It lies on the bottom during the day and feeds mostly at night. This fish is [[anadromous]] and moves upriver into shallow waters to spawn.<ref name=NatureGate/>

==Uses==
[[File:Odesa bazaar (8) Sturgeon.JPG|thumb|left|250px|Starry sturgeon in a bazaar in [[Odesa]], [[Ukraine]]]]
The starry sturgeon is an important commercial species of fish. It is one of the three most important species for caviar, see [[Sevruga caviar]], along with the [[Beluga sturgeon]] and the [[Russian sturgeon|Ossetra sturgeon]]. Its flesh is considered an expensive delicacy in the Caspian region. It is used to make [[kabaab]]s, or is consumed pan fried, broiled, or smoked. There have been several attempts in Russia, [[Iran]], [[Italy]], and the United States to adapt this species for [[aquaculture]], with varying degrees of success.((Citation needed|date=February 2021))

The resilience of this species is low. The minimum population doubling time is 4.5 – 14 years.
