Phases Of Pregnancy In Cherry Shrimp
There are four distinct phases of pregnancy in cherry shrimp;
Phase 1: (Egg Development Stage)
This phase is also known as the egg development phase. The female shrimp develop eggs in their ovaries. These eggs are usually visible to the naked eye.
During this phase, the female shrimp carries and nurtures developing eggs beneath her abdomen. Acquiring knowledge about this stage is essential for ensuring the overall well-being and prosperous breeding of cherry shrimps.
Egg Formation
In this phase, the female cherry shrimp’s ovaries produce tiny and transparent eggs. These eggs gradually undergo transformations as they progress in development. Over time, they become more opaque and may acquire a light yellow or orange tint, indicating the ongoing changes occurring within.
Incubation Period
The duration of the egg development phase typically spans between two to three weeks.
However, the exact timeframe may vary due to factors such as water temperature, quality, and the health condition of the shrimp.
During this period, diligent monitoring of the eggs’ progress, including changes in color and appearance, is crucial.
Optimal Conditions For Egg Development
Creating an optimal environment is paramount to supporting the healthy development of the eggs during this phase.
Maintaining stable water parameters, including temperature (around 72-82°F or 22-28°C), pH levels (6.5-8.0), and water hardness (4-8 dGH), is vital.
Additionally, providing a clean and well-filtered aquarium with suitable hiding spots and abundant vegetation contributes to a stress-free environment for pregnant shrimp.
Nutrition for Egg Development
A well-rounded diet plays a pivotal role in the successful development of the eggs. Ensure a diverse and nutritious diet that includes specialized shrimp foods like algae, biofilm, and commercial shrimp pellets.
These food sources are packed with essential nutrients, minerals, and proteins that promote optimal growth and vitality of the eggs.
Phase 2: (Egg Transportation Stage)
The second phase also known as the egg transportation stage occurs once the saddle of a cherry shrimp grows large enough to extend to its tail’s downward curve then, it is ready for fertilization.
This phase is also known as the essential phase in the reproductive cycle of pregnant cherry shrimp.
It follows the initial fertilization stage when the female shrimp carefully carries her developing eggs until they are ready to hatch.
Also in this stage, the shrimp transport the eggs from their ovaries to their legs, where they hold them. When female cherry shrimp are ready to have their eggs fertilized, they tend to hide.
They may seek shelter in a cave or plant cover, especially if there are other fish species in the aquarium that may view the eggs as a tasty treat.
During this waiting period, the shrimp release pheromones to attract male shrimp. Within one to three weeks, a healthy male shrimp will breed with the female.
Understanding the intricacies of this stage can help aquarists enhance their breeding efforts and create optimal conditions for the survival and growth of the next generation of cherry shrimp.
The following below are important during this stage:
Attachment and Incubation of Eggs
Once fertilized, the female cherry shrimp attaches the eggs securely beneath her abdominal pleopods, utilizing them as a protective shield during transportation.
These pleopods play a vital role in preventing the eggs from dislodging. It’s important to note that during this stage, the eggs continue to develop and require stable water parameters, appropriate nutrition, and an optimal temperature for healthy incubation.
Movement and Behavior
Throughout the egg transportation stage, pregnant cherry shrimp display distinct behaviors associated with safeguarding their precious brood.
They diligently move their pleopods, gently rotating and adjusting the eggs’ position. This movement ensures proper oxygenation and prevents the growth of harmful bacteria or fungi.
Maintaining a tranquil environment is crucial during this period to minimize stress on the pregnant shrimp and promote successful egg development.
Phase 3: ( Berried Stage)
Once mating occurs, the cherry shrimp enters the third stage of pregnancy, known as the “berried” stage. During this time, the shrimp fans her tail to help the eggs receive oxygen and develop properly.
It is important to use an aerator instead of a filter at this stage to ensure optimal conditions for the shrimp eggs.
While both filters and aerators clean the water, aerators increase oxygen levels and reduce water flow, which is ideal for shrimp egg development.
If you don’t have an aerator, you can use thick layers of filter wool to slow down the water pump.
Phase 4: (Birth Stage)
The fourth stage is also known as the Birth stage or phase, in this phase the female shrimp will release her hatchlings. The pregnancy period for shrimp lasts between 20 to 31 days.
A cherry shrimp can give birth to a range of 21 to 51 shrimp in each brood. It is important to consider how the new offspring will fit into the tank and determine if you need a larger aquarium to accommodate them.
This phase also marks an exciting and crucial time in their reproductive journey. During this phase, these tiny aquatic creatures are about to bring new life into the world.
In this article, we will delve into the intricacies of the birth process in cherry shrimp, shedding light on the remarkable transformation and the key considerations to ensure a successful and healthy delivery.
