Farmers need to know the differences between male and female shrimp before hatching. This aims to ensure that the spawned parent shrimp have different sexes with the correct amount ratio.
However, determining the difference between male and female shrimp is sometimes tricky because the two look very similar at first glance. However, some traits can be observed to find the difference.
What are these characteristics? Here we have summarized it for you in this article. So, make sure to read it all the way through.

The Difference between Male and Female Shrimp
The difference between male and female shrimp can be identified from their genitals. In male shrimp, the genitals are in the form of petasma, located on the first swimming leg, which transfers sperm.
Meanwhile, the female shrimp’s genitals are known as thelycum, which is located between the fourth and fifth leg of the road and functions to store sperm.
The female reproductive system uses a pair of ovaries, oviducts, genital openings, and thelycum. While the male reproductive system uses the testes, vasa deferensia, petasma, and masculine appendix.
In addition, the difference between male and female shrimp can also be seen in their body size. The female shrimp parent usually has a larger size than the male parent.

Criteria for Ideal Shrimp Brood
The ideal female shrimp parent is a parent that has mature eggs. The maturity of the eggs is measured based on the development of the ovaries, which are located on the dorsal side of the shrimp’s body. The ovaries are green the more mature they are, the darker the color.
While the development of perfect petasma determines male shrimp. Usually, this petasma contains a spermatophore.
From the physical condition, the shrimp chosen as broodstock must have at least a minimum weight of 100 grams for females and 80 grams for males. Also, ensure the parents do not have defects or injuries, especially on the reproductive organs, to produce high-quality shrimp seeds.
To determine whether the eggs in the parent have matured, it is usually done in two ways: lifting the female and facing the lower body (ventral) towards the sun. In addition, you can also use a waterproof light beam to observe it.
