"roe. Formerly omnipresent in the region, heavy fishing of the sturgeon for caviar has forced it to Critically Endangered Species status. The Persian sturgeon feeds at the shelf zone of the sea, primarily in the eastern part of the South Caspian. Individual specimens are found in the North Caspian, western part of the Middle and South Caspian. The Persian sturgeon is a heterotroph equipped with tactile and gustatory receptors; when feeding it simply sucks in its food. The eating habits of the sturgeon change throughout its life. As it begins life the sturgeon feeds on invertebrates including Mysid shrimp, Chironomid"
"human delicacies in many parts of the world. ""Caviar"" is a name for the processed, salted roe of non-fertilized sturgeon. The term ""soft roe"" or ""white roe"" denotes fish milt. Lobster roe is called ""coral"" because it turns bright red when cooked. Roe (reproductive organs) are usually eaten either raw or briefly cooked. ""The reproductive behaviour of fishes is remarkably diversified: they may be oviparous (lay eggs), ovoviparous (retain the eggs in the body until they hatch), or viviparous (have a direct tissue connection with the developing embryos and give birth to live young). All cartilaginous fishes—the elasmobranches (e.g., sharks,"
"Caviar Caviar (less often, caviare) is a delicacy consisting of salt-cured roe of the Acipenseridae family. The roe can be ""fresh"" (non-pasteurized) or pasteurized, with pasteurization reducing its culinary and economic value. Traditionally, the term ""caviar"" refers only to roe from wild sturgeon in the Caspian Sea and Black Sea (Beluga, Ossetra and Sevruga caviars). Depending on the country, ""caviar"" may also be used to describe the roe of other fish such as salmon, steelhead, trout, lumpfish, whitefish, carp, and other species of sturgeon. Caviar is considered a delicacy and is eaten as a garnish or a spread. According to"

In the province of New Brunswick, roe (caviare) of the Atlantic sturgeon is harvested from the Saint John river. Roe from the cisco is harvested from the Great Lakes, primarily for overseas markets. Roe is also extracted from herring, salmon, and sea urchins. In coastal British Columbia, Fraser River white sturgeon are sustainably farmed to produce caviar. In Chile, sea urchin roe is a traditional food known as an ""erizo de mar"". Chile is one"

As a seafood, roe is used both as a cooked ingredient in many dishes and as a raw ingredient. The roe of marine animals, such as the roe of lumpsucker, hake and salmon, is an excellent source of omega-3 fatty acids.

It is followed in prestige by salmon roe, called ""red caviar,"" which is less expensive, but still considered a delicacy. More common roes, such as cod, pollock, and herring are everyday dishes.

Sturgeon are primarily benthic feeders, with a diet of shells, crustaceans and small fish. Exceptionally, both ""Huso"" species, the white sturgeon, and the pallid sturgeon feed primarily on other fish as adults. They feed by extending their syphon-like mouths to suck food from the benthos. Having no teeth, they are unable to seize prey, though larger individuals and more predatory species can swallow very large prey items, including whole salmon. Sturgeons feed non-visually. They are believed to use"

Many Conservative rabbis now view these particular fish as being kosher, but most Orthodox rabbis do not. The question for sturgeon is particularly significant as most caviar consists of sturgeon eggs, and therefore cannot be kosher if the sturgeon itself is not. Sturgeon-derived caviar is not eaten by some Kosher-observant Jews because sturgeon possess ganoid scales instead of the usual ctenoid and cycloid scales.

Like fish in general, it is considered pareve. Roe is considered kosher only if the fish from which it's harvested is kosher as well. This means that sturgeon roe is not considered kosher from an Orthodox Jewish perspective. For most Orthodox Jewish consumers who keep kosher, roe or caviar must be processed under kosher supervision as well. The only exception to this rule is red roe, thanks to a widely"

Adults feed almost entirely on small benthic bony fishes, including soles, herring, mullet, gobies, goatfishes, porgies, dragonets, and jack mackerels. Large decapod crustaceans are a minor secondary food source, while very rarely skates may be consumed. Juveniles are less exclusively piscivorous than the adults and feed on a variety of invertebrates as well. The most significant prey species differ between seasons and geographic regions.

Behavioral differences are more clear, especially the dietary habits. Adult Gulf sturgeon eat primarily, or possibly only, during the winter, when they are in marine or brackish water, and eat little to nothing during the remainder of the year when they are in rivers. Their weights vary in accordance with this eating pattern, with significant weight gains in the winter and smaller weight losses in the summer. Because their diet consists of mollusks that can cause paralytic shellfish poisoning (PSP), in addition"

It was once thought that the production of the toxin in gar roe was an evolutionary adaptation to provide protection for the eggs. However, bluegills and channel catfish were fed gar eggs and remained healthy, even though they are the natural predators of the gar eggs. Crayfish were not immune to the toxin and most of the crayfish that ate the roe died. The immunity to the ichthyotoxins in bluegills and"
"primary foods of sturgeon while in freshwater areas include soft-bodied annelids, arthropods, aquatic insects, and globular mollusks. Adults that have emigrated from estuaries and into the sea will usually feed on epibenthic and hyperbenthic amphipods, grass shrimp, isopods, and worms. Most adult sturgeon will also feed on detritus and biofilm. Sturgeons are most generally known for feeding on crustaceans, worms, and molluscs. Larvae-juvenile feeding was at the bottom, benthic foraging. However, food in the benthic zone is scarce, so many adapt drift feeding, in which they have holding positions in the water column and wait for food. Sturgeons may have"

Juveniles have been observed with stomach contents with as much as 90% nonfood items, leading to a belief that they randomly vacuum the bottom. Adults in fresh water primarily eat mollusks, supplemented by polychaetes and small benthic fish in estuaries or crustaceans and insects in fresh water. The largest population, estimated to be at least 60,000 adults in 2007, is found in the Hudson River. The second-largest, 18,000 adults and roughly 100,000 of all ages, is in the Saint John"

The salt raises the osmotic pressure of the brine above the zone where bacteria responsible for rotting can thrive and prevents decomposition of proteins into oligopeptides and amino acids. Instead, the osmotic conditions enable ""Haloanaerobium"" bacteria to thrive and decompose the fish glycogen into organic acids, making it sour (acidic).
