The terms in the cultivation of vannamei shrimp are quite diverse. These terms may be foreign to those of you who are new to this industry. For example, Day of Culture (DOC), Survival Rate (SR), and so on.
All terms in vannamei shrimp cultivation are made to make it easier for farmers from various regions to know each of the cultivation parameters they are doing.
So that you don’t have trouble understanding the terms in shrimp farming, here is an explanation that we have collected. Read more in this article!
1. DOC (Day of Culture)
DOC or Day of Culture refers to the age of the shrimp in the pond or the number of days they have been cultivated until the time of harvest arrives. In aquaculture, the term DOC is widely used to determine the age of shrimp.
DOC is different from PL or Post-Larvae in that PL does not refer to the age of the shrimp. Instead, OT refers to the age of fry following hatchery metamorphosis from Mysis.
2. FCR (Feed Conversion Ratio)
FCR or Feed Conversion Ratio is the result of calculating the effectiveness and efficiency of the feed stocked in shrimp ponds. Through FCR calculations, farmers can find out whether the feed given is actually eaten by the shrimp or is left over and becomes waste.
In Indonesian, FCR is also known as the feed conversion ratio which can indicate the level of efficiency of feed management in every cultivation that is carried out. The smaller the FCR number, the more efficient the feed management is.
3. ABW (Average Body Weight)
ABW stands for Average Body Weight which shows the average weight of shrimp in a pond in a certain period.
To get the ABW figure, it is necessary to know the shrimp biomass periodically and then calculate the average.
4. SR (Survival Rate)
The next term in shrimp farming is SR or Survival Rate. Survival Rate shows the level of shrimp life in one cultivation period. Survival Rate figures are usually shown in percent.
Survival Rate is obtained from the comparison between the number of shrimp harvested and the number of shrimp stocked at the beginning of cultivation.
5. PL (Post Larvae)
Post Larva or PL is a term in the cultivation of vannamei shrimp which indicates the age of the fry and the units are expressed in days.
Post Larvae are counted from the completion of the mysis stage until the fry is stocked in the ponds. After the fry was stocked in the ponds, the calculation of the age of the shrimp changed from post-larvae to DOC (Day of Culture).
Tonnage is the total weight of vannamei shrimp based on the harvest carried out. The units of tonnage can be kilograms (kg) or tons.
The term in tonnage vannamei shrimp farming is used to indicate the total weight of all types of harvest. This includes partial and total harvests.
7. MBW (Mean Body Weight)
The next term in vannamei shrimp farming is MBW or Mean Body Weight which is the average weight of shrimp per head. The units used for MBW are usually grams.
To get the MBW of vannamei shrimp, farmers can use the sampling method with anco. The shrimp that were successfully retrieved from the anco were then weighed and counted to get the MBW value.
