Fish School Transforming Indonesian Shrimp Farming with Innovation

Ahoy there, matey! Avast ye to the second part of this swashbuckling series! In The Crust, we have discussed a few times before the merits of using a nursery and multiphase system. But let’s revise a bit shall we?
What is a nursery and multiphase system?
The nursery system involves nurturing shrimp in smaller specialized tanks or ponds during their early developmental stages, usually in the first 10-20 days and high density 2-10 PL/Liter.
Once the shrimp reach a certain size, they are transitioned to larger grow-out ponds in the multiphase system. The shrimps are quickly caught, weighed, and transferred to another pond. Here, farmers meticulously manage the shrimp’s growth phases, employing strategic feeding schedules and water quality control to maximize productivity. Farmers can determine the amount of “phases” in their farm. Even Though it’s a lot to be done, a multi-phase system can have a 4-6 cycle of shrimp production per year!
While Vietnam faced a few hurdles of their own, such as poor water quality and higher production costs, they cleverly invested in developing a more intensive biosecure system that sacrifices 50-70% of farm area for water treatment, resulting in a whopping 4-6 kg/m2 of biomass yields. Then they increase the number of production cycles per year to at least 4 cycles. Indonesia, on the other hand, has been lagging behind with only 2-3 kg/m2 of biomass yield with about 2.5 cycles per year.
Visualizing system and biosecurity improvements
On the left, we have the conventional pond with a 30% failure rate. But fear not! On the right, feast your eyes upon the improved pond with a mere 10% failure rate - a true marvel of predictability!
How did we achieve such a feat, you ask? By refining our farm manage- ment protocol and instilling a culture of discipline among our employees. It’s true what they say, my dear friend - the key to success lies in unwavering commitment to a solid strategy and unwavering discipline.
