Proximate Content of “Klekap” (Microphytobenthos and Their Associated Meiofauna) from Milk-Fish Pond

Abstract

Microphytobentos and their associated mieofauna (‘klekap”) have important role in milkfish pond ecosystem expecially traditional fish pond. Microphytobenthos and their associated meiofauna not only consists of unicellular microalgae from class Bacillariophyceae, Cyanophyceae, Chlorophyceae but also a lot of meiofauna such as Nematoda, Annelida, Mollusc, Arthropoda, etc. Microphytobenthos and their associated meiofauna inhabit in the upper most surface sediment layer. They also have important role in the primary and secondary productivity. This research has purpose to investigate the composition of proximate in the microphytobenthos and their associated meiofauna. Microphytobenthos and their associated meiofauna were taken from three milkfish ponds in Pati area, Central of Jawa, Indonesia. Samples were taken directly by hand core from 3 stations with 3 replications. The research result showed that the value of protein content had range 6.9±0.33 - 7.73±0.37 %-dw, the value of carbohydrate content had range 10.44±1.2 - 12.59±0.15 %-dw, the value of lipid content had range 0.86±0.07 - 0.96±0.07 %-dw. It concluded that the third station has higher value of protein, lipid and carbohydrate compared than the first and the second station.
