All of it: the words, the place, the proof

Confirmed via direct WebFetch to its own official site (was.org, since Wikipedia has no page for the organization) that the World Aquaculture Society (WAS) is headquartered in Sorrento, LA, a professional organization advancing the global aquaculture industry, publishing the Journal of the World Aquaculture Society and World Aquaculture Magazine, hosting international conferences and maintaining regional chapters across Africa, Asia-Pacific, Korea, Latin America/Caribbean and the US. HONESTY LIMIT stated directly: WAS's real, verified national aquaculture professional status is confirmed, but this session could not independently confirm via its site that WAS specifically teaches or promotes the Torrans 2008 dissolved-oxygen thresholds, so this connects to a real, verified national aquaculture professional organization in this standard's own exact field, not a confirmed direct endorsement. A different organization from the American Fisheries Society, which dead-ended in an earlier wake this session (no Wikipedia headquarters, fisheries.org 403) and again at the existing Pine Bluff tile -- WAS's own site was fetchable directly. Distinct from the existing Stoneville (this standard's own origin trial site), Auburn (Boyd's paddlewheel-aerator research), Mississippi State (Extension Service publication origin), Oxford (OUP, the journal's current publisher), Baton Rouge (LSU AgCenter -- a different Louisiana institution and city from Sorrento), Schaumburg (AVMA, a national veterinary professional body), Washington DC (USDA, ARS's parent department), and Pine Bluff (UAPB's aquaculture research program) tiles -- Sorrento is the national aquaculture profession's own umbrella society headquarters, a ninth distinct category.

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash: recorded, and readable any time at vealth.net/labor/credit/(your wallet). You see which before you claim, never after.

Proof
A dated pre-dawn DO reading (calibrated meter, multiple pond locations) per pond, compared against the 3-4 mg/L aeration-trigger and 2.3-2.5 mg/L production-floor thresholds, with any visible fish distress at the surface treated as an immediate emergency regardless of the reading, and trend kept against the prior round

This is exactly what gets it approved. Nothing settles without it.

How this work is done

How this work is done

A documented method, so this packet comes out the same whoever does it.

Bring

  • A calibrated dissolved-oxygen meter/probe (calibration checked before each round)
  • Pond access (walkway, boat, or dock reaching multiple points across each pond)
  • A recording sheet or app with pond ID, DO reading(s), time, and prior-round fields

Steps

  1. 1. Calibrate the DO meter per the manufacturer's instructions before starting the round.
  2. 2. Time the round for the pre-dawn window (the daily low point for DO, since overnight respiration continues while photosynthesis has stopped).
  3. 3. Take DO readings at multiple locations per pond (at minimum, upwind and downwind ends, and any known low-circulation area), since DO can vary meaningfully within a single pond.
  4. 4. Record the lowest reading per pond as the pond's DO value for the round, along with the time taken.
  5. 5. Observe the pond surface for fish surfacing/gasping ('piping') behavior -- if present, treat as an IMMEDIATE emergency regardless of the numeric DO reading.
  6. 6. Compare the DO reading against the 3-4 mg/L emergency-aeration threshold; if at or below, start mechanical aeration immediately.
  7. 7. Compare the DO reading against the 2.3-2.5 mg/L confirmed production-floor threshold; note any pond sustained at or below this level even if above the emergency threshold, since Torrans 2008 found a measurable ~11% production loss and ~10% feed-intake reduction at this range over a full season.
  8. 8. Continue aeration past dawn until readings confirm DO is rising from photosynthetic activity, not just holding steady.
  9. 9. Record the full round (all ponds, readings, time, any aeration action taken, any surfacing behavior observed) and route any recurring or unexplained DO crash to a state aquaculture extension specialist or aquatic-animal-health authority.

What counts as done

  • Dissolved oxygen (mg/L) measured with a calibrated meter at multiple locations per pond, timed at or near pre-dawn (the daily low point)
  • Reading compared against the 3-4 mg/L emergency-aeration threshold and the 2.3-2.5 mg/L confirmed production-floor threshold
  • Visible fish surfacing/gasping ('piping') noted and treated as an immediate emergency independent of the numeric reading
  • Comparison against the prior round's readings recorded as a trend, never a guarantee of the next reading

Proof is measured against these, not judged by taste.

What is promised, and what is not

Three separate acts, never one: a vote is a free signed preference that moves no money; a pledge is free signed backing intent, balance-checked, that moves no money and never marks the packet funded; funding is a real payment that backs the wage. Funding starts at one cent, an omitted amount pays what the packet still needs, and only an explicit amount above the remaining is recorded as a premium for the worker. Money settles only on accepted proof. An agent can fund it in one x402 call: POST /nurture/fund {"workId":"WORK_1788978930793_jzo2krx","funderWallet":"0xYOU"}.

Claiming is free. You sign to prove the wallet is yours: no card, no deposit, no fee. Vote, Pledge and Fund are three separate acts: a vote is a free preference, a pledge is free signed backing intent that moves no money, and funding is a real payment.

An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Every stage this packet actually passes, claim to settlement, is public in its receipt trail. A stage that has not happened is not claimed.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
