Embodiment
As shown in the figure, the phototactic experimental provision of zooplankton in a kind of research water, comprise casing 2 and light source 1, described light source 1 is arranged on outside described casing 2, box body wall near light source side is the printing opacity box body wall 4 that quartz glass is made, and ensures that ultraviolet or visible light transmittance rate reach more than 95%.All the other box body walls are alternatively non-transparent box body wall, are made up of black non transparent plastic plate.In described casing, be provided with 3 pieces of dividing plates 5, described casing 2 inwall is provided with chute, described dividing plate 5 is arranged on described in chute, and described dividing plate 5 is demountable structure.Space in casing 2 is divided into the compartment that 4 sizes are identical by 3 dividing plates 5.Each compartment is provided with discharge outlet 6.All closed above 4 compartments, only have on the closed cover above the first compartment of close light source and establish water filling port 3, so that from water filling port 3 injection experiments water sample and put into zooplankton.
The present embodiment for object, carries out the phototaxis research of cyclops with the cyclops occurred in water factory of Shandong Province water treatment technology.
Step:
(1) first extract the plastic septum 5 between compartment out, add experiment water sample and 50 cyclopss from water filling port 3, close water filling port 3, make it be placed in the environment 10min of complete darkness, make that cyclops is relatively uniform to be distributed in four compartments.
(2) light source arrangement is in quartz glass outer surface center, adopts UV-A 365, UV-B 297nm, UV-C 254nm ultraviolet lamp tube (crest is respectively 365nm, 297nm, 254nm) and fluorescent lamp to test respectively.
(3) open light source 1, irradiatometer light intensity is estimated instrument to record quartz glass inner surface light intensity is 20 ~ 25 μ W/cm under water
2, insert dividing plate 5 after irradiating 5min, use the zooplankton filter screen of 30 μm below the discharge outlet 6 of four compartments, to filter each compartment draining respectively, zooplankton in each compartment water is counted.
(4) the phototaxis index of cyclops under each light source is calculated after counting.
Phototaxis indices P I=(R-L), in publicity, letter represents the percentage that zooplankton quantity in respective compartment accounts for sum.
PI span is between-1 to 1.Strong and weak according to phototaxis, PI is divided into 5 grades :-1 ~-0.6 is strong negative phototaxis;-0.6 ~-0.2 is weak negative phototaxis;-0.2 ~ 0.2 thinks without phototaxis; 0.2 ~ 0.6 is weak photopositive; 0.6 ~ 1 is strong photopositive.
This experiment carries out 4 times altogether, and the phototaxis index of experiment is averaged, and the results are shown in Table 1.
This experimental example of table 1 Water flea Phototactic behavior
