1983-5 Granmar Group, Ecuador - Now called Empagran. Three farms, one processing facility, one feed production mill and with the first large-scale commercial shrimp hatchery in the world Semacua
Ecuador had showed the world early on that farmers could capture wild postlarval shrimp, stock them in ponds and produce a profitable crop of large shrimp but many of the ponds that were constructed for shrimp farming were lying idle because wild seedstock was not always available. So two strategies were pioneered at Granmar shrimp farm.
1. Shrimp nursery pond technology - high density wild postlarvae stocking with associated live shrimp juvenile transport technology - to stock large grow out ponds from nurseries. Result was first commercial year round shrimp farm production in the world.
2. Hatchery seed from Semacua that was trialed in all sorts of stocking combinations, species and ages with PL12 vannamei being the optimal cost/benefit fit but unfortunately it still could not compete in performance or productivity with wild seed. This was because spawns were from captive maturation females bred in hatchery.
On one trip up the coast of Ecuador in 1984 we found abundant vannamei PLs in beach locations. This resulted in a boom in PL supply. Prior to this wild seed was obtained from estuaries.
Unfortunately wild seed capture had a lot of incidental catches associated with the filtration technology used and also used child labour. Hatchery seed made sense to target for our markets - not just for seasonality issues.
Concurrently at Granmar shrimp feeds were trialled from sister feed mill ABA with in-pond cages, different feeding technologies tested and even testing of novel shrimp harvest pumps. Blue sky thinking was encouraged.
