Know your shrimp culture and don’t get bamboozled by your local feed supplier or others into using chemicals in culture.
Vannamei “pacific” shrimp DO NOT originate from the Hawaiian Islands.
They are just as exotic there as in India!

Are you 21 and over….?
…and I don’t mean age but male ejaculation. Yes 21 a month is the magic number to reduce cancer risks as in Spanish health article this past Friday.
Now for vannamei shrimp we know that sperm sacs, after ejaculation or removal for artificial insemination (AI), take around 10 days to regenerate.
Viability of new sperm is better if male vannamei shrimp are kept at lower temperatures during regeneration.
Interestingly when the natural growth plateau in culture hits also around the time one can noting male sperm sacs forming although sexual differentiation can be noted earlier.
Why India went down vannamei route
I don’t have scientific proof for this but I was involved in setting up a frozen meal kit station in Kerala, India back in 2005.
Helped in things like selecting appropriate processing equipment for dicing local vegetables, NPD, even had a go at making one with the local paratha bread. Could not get the right spin on it though 🙂Â
Frozen skillet meal kits based on shrimp were being made for US markets.Â
Blanched and frozen shrimp, color soaked with beetroot dye of course and blanched for food safety quality assurance – which is more or less same as reason cannot buy raw crayfish tails out of China! Â
Shrimp from local fisheries already big US salad shrimp business out of India.Â
Of course back in the day and before my time shrimp out of India used to be canned. Just like pineapples.
Local shrimp in meal kit was later discarded for imported frozen vannamei as more a shrimp US markets are used to. Then push was made for local vannamei source – which meant India had to get into vannamei shrimp farming.
We used local vegetable all found in higher elevations inland. Diced and frozen.
Frozen sauces in cubes and pasta initially from Italy but moved to lower cost commodity pricing out of Argentina with fx advantages
