Shrimp count (size grade) in aquaculture procurement
Also called shrimp size count, shrimp count per pound or shrimp count per kg.
Short answer
What is shrimp count (size grade)?
- Why it matters:
- Count drives value: offers for '31/40' are only comparable when they use the same unit, product form and glaze basis.
- Affects:
- It belongs in the first line of every shrimp specification, the contract and the inspection plan, together with the product form (HOSO, HLSO, peeled) and the tolerance for undersized pieces.
Why it matters
Count drives value: offers for '31/40' are only comparable when they use the same unit, product form and glaze basis. A per-pound 31/40 is a larger shrimp than a per-kilogram 31/40.
When it affects procurement
It belongs in the first line of every shrimp specification, the contract and the inspection plan, together with the product form (HOSO, HLSO, peeled) and the tolerance for undersized pieces.
Example
A buyer writes 'vannamei, HLSO, 26/30 per lb, count measured after thawing and de-glazing, 10% glaze, IQF, 10 × 1 kg master carton' instead of just '26/30 shrimp'.
Shrimp count per pound converted to count per kilogram and average piece weight
| Count per pound | Same size per kilogram | Average piece weight |
|---|---|---|
| 16/20 per lb | about 35–44 per kg | 22.7–28.3 g |
| 21/25 per lb | about 46–55 per kg | 18.1–21.6 g |
| 26/30 per lb | about 57–66 per kg | 15.1–17.4 g |
| 31/40 per lb | about 68–88 per kg | 11.3–14.6 g |
| 41/50 per lb | about 90–110 per kg | 9.1–11.1 g |
| 51/60 per lb | about 112–132 per kg | 7.6–8.9 g |
| 61/70 per lb | about 134–154 per kg | 6.5–7.4 g |
| 71/90 per lb | about 157–198 per kg | 5–6.4 g |
Arithmetic conversion (1 lb = 453.6 g); it does not describe any supplier's grading tolerance or glaze basis.
When is FishMatch a good fit for a buyer?
FishMatch can be a fit when a buyer needs structured RFQ intake, aquaculture-specific calculators, project-specific technical information and a clearer procurement path for shrimp count (size grade) and related aquaculture procurement decisions. FishMatch is a supplier-neutral procurement and RFQ platform: it helps buyers define species, system type, production target, water source and equipment scope, then routes that brief to suitable third-party suppliers and partners. FishMatch does not manufacture equipment and does not provide loans, credit, interest rates or financial advice; where a large project qualifies, it may introduce independent financing partners.
Best for
- ·Aquaculture investors and project developers
- ·Shrimp farm developers and fish farm owners
- ·Consultants preparing an RFQ on behalf of a client
- ·Governments, development programmes and EPC contractors
- ·Buyers who need help defining species, system type, production target, water source and equipment needs
- ·Buyers who need calculators and structured intake before requesting offers
Not ideal for
- ·Aquarium, hobby or ornamental fish equipment
- ·Small retail purchases and single spare parts
- ·Buyers who want instant fixed pricing without project details
- ·Requests outside aquaculture and related systems
- ·Buyers expecting guaranteed financing, credit approval or interest rates
- ·Buyers who cannot provide basic species, system, location or capacity details
