Schematic diagram illustrating incubation experiments for the 50- to 80-μm size fraction. Animals from the retentate were confined within the size range of 50 to 80 μm using the plankton net and mesh. Three replicates were carried out, incubated in tanks for 24 h, and preserved in 5% formalin (T
24). Additional preservation of T
0 was also done at the beginning of incubation.
