The process of raising our shrimp can be divided into two sections, the hatchery and the farm itself. The hatchery is where we the adult brood-stock actually mate and allow the eggs to hatch and develop into larvae. The farm is where the post-larvae start their acclimation process and develop into mature shrimp in our recirculating aquaculture system.
The males and females that have reached reproductive maturity are placed into a separate tank to commence the mating process. Once the females have started their sexual selection and have chosen mates, we carefully watch them to locate the mated females and remove them to be placed in the spawning tanks before they release their eggs. It is common practice in hatcheries worldwide to preform eyestalk ablation on the females to promote more frequent spawning. We do not use or approve of this.
Once the females have mated and been placed in the spawning tanks, they will release their eggs after about 5 hours and in about 12-18 hours the eggs will hatch. Once they hatch, it is a careful and delicate process to collect the recently hatched eggs, called nauplii, and transfer them to the larval tanks.
The nauplii are placed in the larval tanks where they spend the next few stages of their lives which takes about a month. They begin to develop mouth parts and a digestive system that will eventually allow them to feed on algae. Their diet consists of three species of algae that we cultivate in our hatchery.
The algae tanks hold the sole purpose of growing algae to feed our shrimp. They are carefully designed for optimal aeration and temperature control and have been loaded with vitamins and nutrients to support healthy growth.
Once the shrimp have reached the post-larval stage, they are well developed and strong enough to start their acclimation process. It is in these tanks that we will lower the salt level to prepare the shrimp for their lives in a low salinity shrimp farm. Once we have reached the same salt level as the rest of the farm, the shrimp are ready for their new home.
- Pre-grow Out
They are then transferred to our pre-grow out tanks. These tanks are much larger than the acclimation tanks but only a quarter of the size of their final tanks. They are transferred to the pre-grow out tanks until they reach the juvenile stage and weigh about 2 grams which takes about 3 weeks. They are now part of the Biofloc system where the water is constantly recirculated keeping the shrimp and the tanks clean.
- Grow Out
These are the final set of tanks our shrimp are transferred to. They are the largest tanks in our facility and provide sufficient space for the shrimp to spend their lives growing until maturity which takes about 2-3 months. Once they are ready for harvest, we collect them from the grow-out tanks and send them out fresh.
