Release time:

2022-06-22

The gills of prawns are the organs of direct contact with the outside world, and their defense ability is weak. When the water quality or shrimp constitution is poor, many pathogens will lead to the yellow gills and black gills of prawns. Yellow gills, can be divided into parasitic and bacterial yellow gills. The occurrence of bacterial yellow gill is mainly related to the deterioration of water quality, substrate and the constitution of prawns. Yellow gill is also a precursor of gill rot, treatment is not timely, it is easy to turn into bacterial black gill, further formation of gill rot.

1. Ciliate Parasites

Sick shrimp activity is sluggish, appetite is weakened, the operculum is slightly everted, the gills are enlarged, and many villous light yellow objects are attached to the gill filaments. Microscopic examination showed a large number of dense ciliates attached to the gill filaments.

Solution:

The first day of the evening outsideHigh calcium hard shell treasure(3 mu/bag)➕Aquatic special multi-dimensional(4 mu/bag)

The next day outside the splashoptical fiber(2-3 mu/bag) to kill ciliates.

Third day useBishui Jiedu An JieduandBeautiful bottomChange the bottom, regulate the water quality at the same time kill the bottom ciliates, prevent the ciliates from attaching again.

2. bacterial gill rot

In the early onset of the disease, shrimp gills were pale yellow, with the development of the disease, gill filaments more swollen, loose, and from yellow to brown, serious when the gill tissue becomes brittle, or even erosion, black gills and gill rot phenomenon.

Solution:

The first day of the evening outsideHigh calcium hard shell treasure(3 mu/bag)➕Aquatic special multi-dimensional(4 mu/bag)

The next day outside the splashZhongren Gold Iodine(6 mu/bottle)➕Wuhuang Jiedu Liquid(2 mu/bottle) disinfection.
