飛碟大解構-MONOGENEANS Benedenia(貝尼登吸蟲)
UFO出世至自由游水只須 4 天,出世後 7 天已成長再繁殖下一代…
"Transmission:
Transmission is horizontal and pre-disposing factor is overlapping generation of cultured fish. High stocking density provides greater opportunity for infecting the fish host by the monogenean. The eggs of skin monogeneans are tetrahedral in shape with long spiral filament and are usually attached on tank walls and nets. The egg hatches into a free-swimming larval stage, the oncomiracidium, in 4 days. The larvae attach onto a suitable host and mature in 7 days after hatching."
