RESPON FUNGSIONAL IKAN MUJAIR (Oreochromis mossambicus Peters) TERHADAP KEPADATAN POPULASI LARVA NYAMUK (Aedes aegypti L.)
Abstract: The functional
response of Oreochromis mossambicus Peters to prey density (larva Aedes aegypti
L) had been studied on December 2013 until February 2014 in Laboratory
Department of Biology-Chemistry, Faculty of Technique, Mathematics and Natural
Sciences, Indraprasta University, Jakarta by using Holing Methods. Experiment
was arranged with Randomized Block Design (RBD) factorial, where the first
factor (A) was the size of Oreochomis mossambicus (2, 4, 6 cm). The second
factor (B) was the density of larva mosquito (5, 10, 15, and 20
individual/lit). The result of this study showed that the time for searching
the prey by predator decreased at the increase of prey density. The handling
time decrease with the size of fish Oreochromis mossambicus, it increases prey
density. In treatment with the fish about 2 cm length with density of Aedes
aegypti larvae 5, 10, 15, and 20 the handling time is 40,48; 14,47; 9,75; 7,75
second respectively and the fish size 4 cm is 29,73; 15,37; 9,60; 7,30 second.
The fish size 6 cm didn’t eat mosquito larvae. The model of functional response
of Oreochromis mossambicus Peters density of mosquito larvae of Aedes aegypti
is the type III (sigmoid).
