That said, studies directly linking caviar intake with improved heart health in humans are needed. Caviar is an excellent source of omega-3 fatty acids that reduce heart disease risk factors. However, human studies specifically investigating the link between caviar intake and heart health are needed. Research suggests that omega-3 fatty acids play a crucial role in male fertility Sperm has a particularly high DHA content, and studies suggest that low DHA levels may be associated with low sperm quality.
In fact, DHA deficiency is typical in men with infertility 19 , On the contrary, fertile men tend to have higher blood and sperm levels of omega-3 fatty acids Eating more omegarich foods may improve sperm structure, shape, and fluidity, which may help sperm bind more easily to eggs to increase fertility 19 , 21 , For example, one rodent study looked at the effects of a caviar-derived product on sperm quality and quantity, finding that it significantly increased sperm count , motility, and survival Again, due to its high omega-3 content, caviar may improve male fertility, although human studies are lacking.

The omega-3s in caviar may also boost male fertility. However, keep in mind that most research is based on test-tube or animal studies, often using extracts, and that studies in humans eating fresh caviar are needed to learn more about the effects.

Hackleback sometimes called shovelnose sturgeon are found throughout the Mississippi and Missouri river system. Historically, the Caspian Sea, Black Sea and surrounding region was home to the sturgeon producing the most sought-after caviars like beluga, osetra and sevruga. Near the end of the 19th century, America became the world caviar leader. Eventually, overfishing and increased water pollution decimated sturgeon populations.
Worldwide numbers haven't recovered despite conservation efforts and restrictions on sales of caviar from wild caught sturgeon. Today, most caviar comes from aquafarms. One-third of all caviar, according to a Business Insider article, comes from sturgeon-farming companies in China. Even with more aquafarm-supplied caviar, the nature of sturgeon and labor intensive work involved keep prices solidly in the special-occasions category for most budgets.
First it takes three to five years before sturgeon can be individually scanned to separate males and females. Depending on the species, it takes eight to 20 years for female sturgeon to reach reproductive maturity.
It's not exact science to know when a sturgeon is filled with roe, so the fish are monitored on a regular basis after they reach maturity.
Sturgeon are slaughtered, then the roe sacks most fish have two are removed immediately to prevent a post-mortem chemical from harming the eggs. The rest of the fish is set aside to be harvested for meat, skin and useful byproducts. Roe sacks are cleaned and rubbed on a mesh screen to separate eggs from the membrane.
The harvested eggs are washed, filtered, drained, salt-cured and graded. Furthermore, caviar is finicky.
