Open WL Archief (OWA)

Over het archief

Het OWA, het open archief van het Waterbouwkundig Laboratorium heeft tot doel alle vrij toegankelijke onderzoeksresultaten van dit instituut in digitale vorm aan te bieden. Op die manier wil het de zichtbaarheid, verspreiding en gebruik van deze onderzoeksresultaten, alsook de wetenschappelijke communicatie maximaal bevorderen.

Dit archief wordt uitgebouwd en beheerd volgens de principes van de Open Access Movement, en het daaruit ontstane Open Archives Initiative.

Abstract

The secondary production of the harpacticoid copepod Tachidius discipes Giesbrecht 1881 was estimated during spring 1979. The population was sampled every 3 d. Three generation peaks were observed. These were clearly distinct in the first copepodite stages, but gradually showed more overlap in older stages. Production of copepodites and adults was estimated in 2 ways: (1) Peaks were separated and the forward shifting of peaks in consecutive stages was used to estimate stage durations; (2) the size frequency method was applied. Both estimates of the production of copepodites and adults are in good agreement: 1.10 g dwt m-2 and 1.02 g dwt m-2. Egg production amounts to 0.31 g dwt m-2; naupliar production is roughly estimated at 1.11 g dwt m-2. The production efficiency, P/(P+R), of copepodites and adults is 0.36; for the total population it is 0.43. This value corresponds well to the value estimated from culture experiments with this population.
