Description
Return feed dry mass and wet mass for a supplied dry target.
Aquaculture material budgets distinguish as-fed mass, dry mass, specific energy and nutrient fractions. Offered feed, recovered feed and estimated intake are different quantities. Arithmetic balances do not determine biological utilization, an appropriate diet, disease status or a safe feeding recommendation.
Return feed dry mass and wet mass for a supplied dry target.
When to use this tool
Use Pond Feed Moisture Dry Matter Factor when checking the stated aquaculture feed, material or composition basis.
How to use the tool and how it works
- Enter wetFeed, moisture, targetDryMatter. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read dryFeed, requiredWetFeed. Use the output convention below.
Return feed dry mass and wet mass for a supplied dry target. Require wetFeed/targetDryMatter >= 0 and moisture in [0,1); dryFeed = wet*(1-moisture), requiredWet = targetDry/(1-moisture).1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| wetFeed | Wet Feed | Required. Finite number; minimum 0. |
| moisture | Wet-basis water mass fraction, strictly below one. | Required. Finite number; minimum 0; strictly below 1. |
| targetDryMatter | Target Dry Matter | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| dryFeed | Dry Feed | Required. Finite number. |
| requiredWetFeed | Required Wet Feed | Required. Finite number. |

}Limitations and assumptions
- The target is supplied, not a recommended ration; nutrient quality, ingestion, species needs and welfare are not assessed.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified feed and animal records, representative measurements and qualified aquaculture/veterinary advice for actual nutrition, welfare or water-quality decisions.
