Production costs of pike-perch fingerlings (Sander lucioperca): a bio-economic model
2003
Kamstra, A.
A major object of the project ‘Lucioperca’ is to estimate economic feasibility of intensive production of pike-perch. An important part of this activity is the reproduction of brood stock and production of fingerling fish for further on-growing. This report describes the specific costs involved in production of fingerlings and is used as subsequent input in the assessment of overall economic feasibility. The production costs for fingerlings are calculated using an Excel-spreadsheet model containing five different linked sheets. Individual sheet are used for input on feeding and growth, investments, production costs and pricing. In the base-case situation, yearly production is 100.000 fingerlings of 10 gram a piece. By shifting the spawning season, two batches of eggs can be obtained a year which increases efficiency. Under these assumptions the costs of producing a fingerling amount to 40 eurocents a piece. Major cost items are labour (26%) and capital costs (38%). Considering the potential market prices for large fingerlings for on-growing or restocking, fingerling production could be interesting.
