Which shrimps have caviar?
Shrimp vary noticeably in appearance because they can belong to different species. Individuals caught in cold waters have different appearances and colors. The color of males depends on their feeding habits, and that of females depends on their readiness for fertilization.

Interestingly, the taste of the meat of male and female individuals is slightly different. Tasters admit that the most delicious are females with caviar.
Most shrimp have caviar in the head, so when choosing seafood, attention should be paid to inspecting the top part. It can have a completely different shade:
- yellow head - offspring are just emerging;
- red - the caviar moves from the head to the body, darkens;
- dark, almost black - the individual fattens after bearing offspring.
A shrimp with caviar will have a yellow or red head. She carries the eggs for 1-1.5 months, and then their ripening occurs in another place. The female transfers the eggs to small paws located on the tail. From time to time she shakes off dead and unfertilized elements so as not to waste energy on feeding them.
Molting Cherry Shrimp
It's no secret that all crustaceans molt periodically. Replacing the old chitinous shell with a new one is the only way to grow. During the molting period, it is especially important for shrimp to have a shelter where the animal remains until its new shell hardens. Also, molting is a way to restore lost limbs. Shrimp lose them under a variety of circumstances (airborne forces day, calling your mother-in-law a mop, etc. =). The shrimp can also lose legs during the molting itself - if it cannot remove any limb from the old shell, the leg comes off. In general, if you suddenly see a legless shrimp, don’t worry, the leg will soon grow back during the next molt.
The success of molting depends on many factors. One of them is the presence of calcium in water. Calcium is the basis of chitin for the shell. An element such as iodine is also very important. It is a coenzyme for the synthesis of chitin. If there is an iodine deficiency, there is a high probability that the shrimp will not be able to molt and will die. Therefore, if crustaceans live in your aquarium, iodinol is your best friend. Of the branded drugs, we can recommend Tetra Vital , which also contains iodine.
Features of shrimp with caviar
The taste of caviar shrimp meat is different. Experts say that this happens due to the influence of physiological processes, such as fertilization and gestation.
The taste of caviar is no worse than the meat itself, which is in the tail, but many people throw it away, why? This is due to the fact that the process of sucking eggs looks rather unaesthetic, which is why many are disdainful to do it.
The eggs may differ in appearance. Much depends on the duration of their existence and the type of maternal individual. Everyone's favorite, the larger tiger varieties spawn black eggs, while the smaller ones spawn yellow, pink or bright orange.
Is caviar with black dots spoiled? This is completely wrong. This change in the appearance of the product indicates the completion of the ripening process and it is suitable for consumption.
Determining the sex of cherry shrimp: male and female
Determining the sex of cherry shrimp is very easy. The female is larger than the male, has a darker red color, and also has a curved underbelly. Once you have shrimp for a short period of time, you will be able to determine the sex without any problems.
It is worth noting that the female cherry tree has a “saddle”. It received this name because of its similarity in appearance to the saddle that is used for horses. Most saddles are yellow, but they can also be green. “Saddles” are a sign of sexual maturity, as well as a good indicator that eggs should be expected to appear in the near future. Green saddles are thought to occur due to the type of genetics in the wild. Cherry shrimp eggs are mostly yellow, but can also be green. If the “saddle” is green, then the eggs will be green and vice versa. There are no differences between green and yellow eggs, i.e. color does not affect the quality of eggs and is not an indicator of health.

Additionally, please note that to start an aquarium with shrimp, we recommend using the Prodibo Starter Box Shrimp kit, which we wrote about in detail in the article about starting a shrimp tank , read it! A good proven set of everything you need.
If you don’t need the whole set, but just need shrimp soil (soil) . Let's pay attention to a specialized soil that many aquarists have already used and are happy with - Dennerle shrimp king active soil.
This substrate is specially cut down to suit the needs of the shrimp farmer. Good for lowering pH and kH and promoting plant growth in a shrimp aquarium.
What are the benefits for humans?
Shrimp and their caviar are a dietary product that optimally fits into the framework of proper nutrition. Only people who do not like the taste of seafood due to their preferences refuse to eat them.
100 grams of crustaceans contain only 90 kilocalories. At the same time, the product is able to saturate the human body with proteins, improve growth and development. It is known that decapod meat has a positive effect on brain activity, improves memory and enhances attention. The product will be useful for those who want to preserve youth and beauty. It contains a powerful antioxidant. The substance stimulates regeneration and slows down natural aging. According to unconfirmed information, the component is able to stop the formation of atypical (cancerous) cells.
Shrimp caviar contains a healthy complex of Omega 3-6 unsaturated fats. These are essential substances that fill the body with energy and protect it from viruses.

With periodic use, the following results are achieved:
- the functioning of the visual organs is restored;
- skin condition improves;
- the functioning of the skeletal system is normalized, the growth of hair and nails is accelerated;
- the functions of the hematopoietic system are stimulated;
- immunity increases.
Shrimp caviar contains many vitamins: magnesium, potassium, calcium, phosphorus, iron and iodine. The product is useful for children, pregnant women and young children. Its main feature is that, unlike other seafood, it does not provoke allergic reactions (when consumed in moderation).
Feeding cherry shrimp
Cherry shrimp
Feeding cherry shrimp is very easy; they accept virtually any type of food: blanched spinach, zucchini, algae, fish food, bloodworms and much more. In a word, cherry cats are not picky about any food. If shrimp are kept in a species aquarium, it is better to feed them once or twice a week. The amount of food needed for the shrimp should be enough for them to eat it within ~2 hours. Excess feed is bad for shrimp. Overfeeding can lead to their death and also affect the quality characteristics of the water in the aquarium (nitrogen/phosphates). Remember that shrimp are waste collectors in the wild. They eat everything they find 24/7.
The above applies specifically to a species aquarium with shrimp. When you feed them with all sorts of leaves, by the way, all shrimp adore dry leaves of almond, birch, walnut, you can pick them in the summer, dry them and periodically throw them into the aquarium for the delight of the shrimp. There are also specialized foods for aquarium shrimp. For example, Tetra Crusta Menu for a varied and nutritious diet of shrimp and crayfish.
If the aquarium is shared with fish, then you shouldn’t worry too much about the nutrition of the cherries. They will find their own food - chewing algae and eating fish food that falls to the bottom.
Why shrimp and their eggs can be dangerous to humans
In some cases, shrimp and their eggs can be dangerous to humans. First of all, if he does not digest animal protein. This manifests itself at the initial stage in the form of indigestion with cutting pain in the stomach.
Recently, information has appeared that sea shrimp are capable of absorbing radioactive substances from water bodies, therefore, with frequent consumption of salts, heavy metals and harmful amino acids can settle in the body. Such information has not yet been confirmed and it certainly does not apply to artificially grown shrimp, which are sold en masse in most stores.
Black part of the head
The black stripe on the head of the crustacean represents the digestive tract: stomach and intestines. In the wild, shrimp are omnivores. Therefore, parasite eggs and harmful microorganisms are often present in their stomach.
The intestines constantly contain waste products that give the meat an unpleasant bitter taste. Therefore, when eating seafood, you need to get rid of parts of the digestive tract. When cleaning the product, unwanted organs can be easily identified as they are black in color.

From larva to adult shrimp
Having successfully completed these stages, the larva finally enters the final stage, which is called decapodite. At this stage, it is virtually no different from a mature individual. At this time, her lifestyle is completely changing. The individual, which a few days ago was a helpless larva and was able to independently obtain food for itself, as a result, tries to stay closer to the bottom. This is not accidental because it is near the bottom in the vegetation that you can find a lot of different food. A young shrimp does not stop growing and changes slightly. During this period, the greatest number of moults occur, which become less frequent over time. An adult molts at least once a month.
Caviar development
After fertilization, the testicles (which can number hundreds of thousands), having a dark green color, begin to lighten over time. The larvae appear in approximately four to six weeks. The maturation of larvae is influenced by two main factors: temperature and percentage of salt. In warm water, which contains approximately twenty percent salt, the eggs will ripen faster, which means the fry will appear earlier. During maturation, the eggs are attached to the swimming legs, and the eggs that have not been fertilized are gradually detached.
Bad and good cholesterol
These names are rather arbitrary, since low-density lipoproteins containing bad cholesterol have their own functions and beneficial properties. True, LDL benefits only when they are within normal limits (for example, they support the functioning of the immune system), but if there is too much “bad” cholesterol, then it poses a danger to the cardiovascular system. High-density lipoproteins, which contain “good” cholesterol, on the contrary, prevent heart and vascular diseases.

Cod liver
The product is truly very healthy, rich in essential fatty acids, and one of the best sources of vitamin D. It is recommended to eat cod liver to strengthen the immune system. But with all these benefits, this healthy product is quite high in cholesterol, so for those who have problems with this fat-soluble substance, cod liver will have to be abandoned.

Fertilization
After the eggs appear, the female begins to release pheromones, to which the males actively react and begin to pursue her. Very often at this time fights occur between males. But it is not a fact that the father will be the winner in these fights. The male, having made two or three circles around the female, descends onto her back. Then, if he accepts it, the male dives under her and fertilizes the sperm. This process lasts two to three seconds.
Pairing
But there are frequent cases when one female is fertilized by two, and in some cases, more males. This type of mating is called “communal.”
