What a dried carp pituitary actually does in your hatchery
The pituitary gland stores gonadotropins — the hormones that trigger final oocyte maturation and ovulation. Dried carp glands are the classic, low-cost way to induce spawning in species that do not breed reliably in captivity, and they remain the reference standard against which synthetic analogues are compared.
Why hatcheries keep using it
Predictable dose response, broad species coverage, and no cold chain at the hatchery door. Ground to a micro powder, dissolved in 0.7% saline, injected into the back muscle — a workflow every technician already knows.
- SpeciesGrass carp, silver carp, bighead, common carp, catfish, tilapia (off-label)
- FormDried granules, one gland roughly 2–3 mg; you grind and weigh on site
- BatchEach production lot gets its own COA number, printed on the box

What you will actually receive
No stock images and no renders. Vials, granules, and the plant where the glands are collected and dried.
What is inside one 1 g vial
These values come from the product MSDS and release specification. The COA of the batch you actually receive always takes precedence — ask and I will send it before you order.
| Product name | CARP PG™ — Common Carp Pituitary, dried |
|---|---|
| Source | Sexually mature, live fresh common carp — Cyprinus carpio (Cyprinidae) |
| Form | Dried granules in sealed 1 g vials; one gland weighs roughly 2–3 mg (A–B grade) |
| Appearance | Pale yellow to off-white granules, no caking, no visible impurities |
| Pituitary protein | ≥ 90% |
| Impurities | ≤ 1% — no chemical additives, no preservatives |
| Solubility | Readily dispersible in 0.7% saline, water for injection and distilled water; insoluble in organic solvents |
| Bulk density | 0.8–1.0 g/cm³ |
| Heat limit | Protein denatures above 80 °C — never heat, cook or autoclave |
| Packaging | 1 g sealed vial · 10 vials per printed box · boxes in a reinforced export carton |
| Storage | Sealed, cool, dry, dust-free and dark; 15–25 °C with relative humidity ≤ 60% |
| Shelf life | 24 months from the production date |
| Transport | Not a dangerous good; conventional air or courier freight, 5–30 °C, no rain or direct sun |
| Documents | Batch COA, MSDS, packing list and commercial invoice; health certificate where the plant issues one |
| Use restriction | For fish breeding and fishery research only — not for human or animal consumption |
How one vial is actually used
This is the method printed on the CARP PG™ instruction sheet that ships with every box: dose, solvent, injection sites, and what changes between one injection and two. Water temperature and broodstock maturity always decide the final call.
| Dose | 0.15 mg ±10% per kg of fish body weight, as printed on the instruction sheet |
|---|---|
| Solvent | 0.7% saline, water for injection, or distilled water |
| Preparation | Grind to a micro powder and dissolve. Mix fresh and use the same day — a standing solution loses potency |
| Volume | No more than 5 ml in a single injection |
| One injection | Well-matured broodstock at a suitable water temperature |
| Two injections | Early season or broodstock not fully mature; 6–24 h apart, longer when the water is cold. Usually gives the better spawning and fertilisation rate |
| Weigh first | Clip and weigh each fish so the dose is calculated, not estimated |
| Scaled carp | Into the body cavity behind the pelvic fin base or below the pectoral fin base — needle under the scales, not through them |
| Scaleless carp | Intramuscularly below the tip of the dorsal fin or at the caudal peduncle; press with a finger so the solution does not leak out |
| Afterwards | Withdraw at 45°, disinfect the injection point with iodine |
Four buyers, one product
Fish hatcheries
Routine induced spawning of carp and Chinese carps where natural ovulation is unreliable in ponds and tanks.
Broodstock farms
Synchronising spawns to a production calendar, so fry are ready when ponds and customers are ready.
Pituitary extract producers
Gland as the starting material for reconstituted PGE, or for laboratories preparing their own reference suspensions.
Research & universities
Reproductive endocrinology work, bioassay development and teaching material for aquaculture programmes.
Everything your customs broker will ask for, already in the box
Animal by-products attract attention at the border. I ship with the full document set so clearance is not the reason your fry window is missed.
- COA per batch — protein content, impurities, appearance, batch number
- MSDS (16 sections, bilingual) for your import permit file
- Instructions for use printed in every box
- Packing list & commercial invoice matching the airway bill
Shipping
A box of ten vials is light enough for a courier: DHL or FedEx, door to door, 3–7 days. Cartons go by air freight, 5–10 days plus clearance. Nothing here is a dangerous good, so no special handling is needed.

Import permits
Most destinations require the importer to hold a veterinary or feed import permit. I provide the supplier profile, process description and composition sheet you need to apply — tell me the destination country and I will send the matching document pack.

I am Jeff Liu, based in Xi'an, China. I buy dried carp pituitary from fish-processing plants and ship it to hatcheries myself. There is no marketplace, no sales team and no call centre between us.
When you message the number on this page you reach the person who checks the lot, books the courier and sends you the tracking number. That is the whole reason buyers come back: a question gets an answer, not a ticket number.
