Vannamei Shrimp Life Cycle
Before becoming a shrimp you often find at supermarkets, vannamei has several stages of its life cycle that must be passed. Starting from eggs, nauplius, protozoea, mysis, post-larvae, juveniles, sub-adult, to adult shrimp.
Female shrimp will mate with male shrimp and released up to hundred thousands eggs into the water.
The fertilized egg will then develop to the nauplius stage with a size of 0.32-0.58 mm. At this stage, vannamei shrimp do not yet have a perfect digestive system. Meanwhile, they get their food from the yolk sac.
Nauplius, which doesn’t have the yolk sacs and undergoes a molt, then turns into protozoea. At this stage, the vannamei begins to need food from the surrounding environment, such as phytoplankton.
Vannamei will then undergo three moltings and turn into a mysis. The most visible development of this stage is the emergence of swimming legs (pleopods) and the addition of body segments. At the mysis stage, the size of the vannamei shrimp reaches 3.50-4.80 mm.
When it reaches the post-larva stage, the vannamei shrimp looks like an adult shrimp. At this stage, the shrimp have started to actively move straight ahead. Meanwhile, for farmers to find out the age of the post larvae, add a number behind it, for example, PL 1 for one-day-old post-larva.
The shrimp are referred to as juvenile when it reaches PL 10 or post-larva aged ten days.
Yuwana which is 80-90 days old, can already be called a young shrimp or sub-adult shrimp. Usually, these young shrimp have reached a weight of 21-23 grams per head.
8. Adult Shrimp
To reach the adult shrimp that are ready to be harvested, young shrimp need 25-30 days with an average weight of 28-30 grams per head.
Advantages of Vannamei Shrimp Cultivation
Since its appearance in Indonesia, vannamei shrimp has immediately become one of the potential export commodities. This is because shrimp that are originally from the sub-tropical region have excellent environmental resistance and can adapt quickly.
In addition, several other advantages include high economic value, faster growth, more resistance to disease and an unstable environment, and high viability make this shrimp become the farmers’ choice.
