Description
Return additive-volume pond/inflow salinity mixing.
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 additive-volume pond/inflow salinity mixing.
When to use this tool
Use Pond Salinity Mixing One Inflow when checking the stated aquaculture feed, material or composition basis.
How to use the tool and how it works
- Enter pondVolume, pondSalinity, inflowVolume, inflowSalinity. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read volume, salinity. Use the output convention below.
Return additive-volume pond/inflow salinity mixing. Require nonnegative concentrations/volumes with positive total; salinity is the volume-weighted mean, volume is their sum.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| pondVolume | Pond Volume | Required. Finite number; minimum 0. |
| pondSalinity | Pond Salinity | Required. Finite number; minimum 0. |
| inflowVolume | Inflow Volume | Required. Finite number; minimum 0. |
| inflowSalinity | Inflow Salinity | Required. Finite number; minimum 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| volume | Volume in the unit implied by the stated geometry; no implicit unit conversion. | Required. Finite number. |
| salinity | Volume-weighted supplied salinity, assuming compatible concentration/density conventions and additive volumes. | Required. Finite number. |

}Limitations and assumptions
- This assumes compatible salinity/concentration bases, volume additivity and complete mixing; actual density effects, species suitability and water quality are not evaluated.
- 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.
