How to Use This Calculator

Enter Expected catch (kg), Trip duration (days), and Ambient temp (C).
Set Target temp (C).
Review the Ice needed (kg) result.
Use Ice cost ($) ($) and Refrigeration (BTU/hr) to inform your decision.

How the result changes with Expected catch (kg)

Expected catch (kg)	Ice needed (kg)
50,009	150,027
175,007	525,021
325,004	975,012
450,001	1,350,003

What each input means

Expected catch (kg): Expected total catch in kilograms.
Trip duration (days): Duration of fishing trip in days.
Ambient temp (C): Average ambient temperature during trip.
Target temp (C): Target fish storage temperature (0 C for fresh, -18 C for frozen).

What each result means

Ice needed (kg): Total ice required for the trip.
Ice cost ($): Estimated cost of flake ice.
Refrigeration (BTU/hr): Mechanical refrigeration capacity needed.
Hold volume (cu ft): Minimum insulated hold volume.

How this is calculated

Worked example, using the default values

Identify Input Parameters
4 parameters
Expected catch (kg) = 2000, Trip duration (days) = 5, Ambient temp (C) = 25, Target temp (C) = 0 = 4 input(s) provided
Calculate Ice needed
Ice needed = round(catchKg * iceFactorBase * tempAdjustment * 100) / 100
6000 = 6000
Calculate Ice cost
Ice cost = round(iceNeededKg * 0.10 * 100) / 100
600 = $600
Calculate Refrigeration
Refrigeration = round((catchLb * 0.8 * deltaTF) / (tripDays * 24))
1323 = 1323
