Getting to Know the DOC Term in Shrimp Farming
In vannamei shrimp culture, DOC is also used as a benchmark for the age of shrimp after the larval stage. For example, DOC 80 means that shrimp farming has been carried out for 80 days since the first day the fry were sown.
Are you still confused about what DOC or Day of Culture is in shrimp farming?
When you are new to the world of aquaculture, maybe you find tons of new terms on this industry. One of the is DOC shrimp or Day of Culture.
The term DOC in shrimp farming means the days during which the cultivation of vannamei shrimp in the pond takes place. This DOC begins to be calculated from when the fry stokes into the pond until the shrimp are harvested. Other than that, DOC is also used to calculate the age of shrimp in ponds which is also important for shrimp feed management.
Differences between PL (Post Larva) with DOC (Day of Culture) in Shrimp Cultivation
Most people still don’t know the difference between PL and DOC in shrimp farming. However, they are two different terms because both are often interpreted as referring to the shrimp’s age.
PL stands for Post Larva. This term indicates the shrimp fry’s age, generally in days. PL vannamei shrimp counts after the shrimp complete the mysis stage until it is ready to be stocked in the pond. For example, PL1 means the fry is only one day after completing the mysis stage.
After the PL (Post Larva) is stocked into the pond, the term to indicate the shrimp’s age is changed to DOC or Day of Culture. For example, DOC 30 means that the shrimp fry has been 30 days old since they were stocked into the pond. So, don’t be confused with the term both PL and DOC.
