| dc.description.abstract | Nekton is organisms that can swim and move on their own accord with
example amphibians and aquatic insect. This study aims to determine the structure
of nekton community and relation about physical and chemical conditions in the
Lake Pondok Lapan . This study was carried out from January to March 2015.
Data collection were nekton species composition and abundance, as well as water
quality data as a supporter. Nekton retrieval used fish nett and fishing rod. The
results showed there were 5 of the Ordo, of which 4 ordo belongs to fish and 1
ordo of shrimp. Sepat rawa (Trichogaster trichopterus) was found to be caught at
most in the amount of 141 and 56% relative abundance. Diversity nekton in
Pondok Lapan lake including low at 0,1. General dominance index value
approaching 0 is equal to 0.2. It shows that almost no one species dominates.
Value uniformity tends to approach the number 0 is equal to 0.07. The figure
shows the number of individuals of each type of deployment is not the same.
SPSS correlation analysis results showed that temperature, depth, brightness pH
,DO and COD has a positive correlation with the abundance of nekton while
turbidity and COD have a negative correlation or do not have the relationship with
the abundance of nekton. | en_US |
