The hatchery shown in the video is located in Toledo, San Jose (Brazil). This particular hatchery is a component of an aquaculture project that consists of around 1000 of small volume/high density cages (SVHD cages) of 1.5 meters for each of length, width and depth.

Tilapia reproduced in the hatchery is a genetically improved Thai strain of Nile tilapia (Oreochromis niloticus).

Two protocols of sex reversal have been adopted for the production of all-male tilapia fingerlings whether through feeding the newly swim-up tilapia fry on hormonal treated feed using the sex hormone (17 a-Methyltestosterone) orthrough the immersion of the newly hatched fry in hormone solution for 7 to 10 days. The actual fingerling production of the hatchery in 2014 is 5 million fingerlings produced during 8-month operation. However, the maximum capacity of the hatchery is 12 million fingerlings.
