Abstract
A measuring method of crawling speed of a sea urchin is characterized in that a sea urchin to be tested is placed into a glass water tank filled with sea water, square grid with a side of 5cm is arranged on the bottom portion of the glass water tank, a camera is arranged right above the glass water tank to shoot movement process of the sea urchin, a period of the video which the sea urchin crawls along a straight line of the shooting video is selected, the first frame of the period of the video and the last frame of the period of the video are shoot, and the two screenshots are overlapped, the movement distance of the sea urchin L is calculated referenced to the grid by image measuring software, the movement time of the sea urchin T is calculated by the time intervals of the shot first frame and the shot last frame, and the crawling speed of the sea urchin V is calculated, and V = L / T. at least three sections of videos that the sea urchin crawls in the straight line are selected, and crawling speeds of the sea urchin are calculated by using the mentioned method, and an average value is calculated. The measuring method of the crawling speed of the sea urchin is simple and easy, convenient to operate, not only does not affect normal growing and physiological state of a sea urchin, but also is capable of measuring the crawling speed of the sea urchin.
Description
Technical field
The present invention relates to a kind of biological parameter measuring method of sea urchin, particularly a kind of sea urchin creep speed measuring method.
Background technology
Sea urchin is the general designation of Echinodermata echinoid, and existing sea urchin has kind more than 850 approximately in the world, and China coast has kind more than 150 approximately.Common are horsedung sea urchin, Dalian Anthocidaris crassispina and heart urchin etc.Sea urchin has higher edible, medicinal and scientific research and is worth, and the gonad delicious flavour of Partial Species is nutritious.Along with the raising of China's living standards of the people and the rising of international market demand, sea urchin has become the important object of China coast aquaculture and enhancement releasing in recent years.For cultured output and the enhancement effect that improves sea urchin, Chinese scholars has been carried out a large amount of relevant rudimentary Journal of Sex Research about aspects such as sea urchin biology, ecology and behaviouristics.
In the correlative studys such as the ecology of sea urchin and behaviouristics, creep speed is a very important behavioral ecology index.Sea urchin is creeped by the motion of sucker and quil, and creep speed is slow.But the creep speed of sea urchin and its existence are closely related, and what directly affect sea urchin ingests, hides harmful animal and uncomfortable environment and distribution etc.Yet, also do not have up to now a kind of method of Measurement accuracy sea urchin creep speed.
Summary of the invention
The present invention is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simplely, and convenient operation neither can affect sea urchin normal growth and physiological status, method that again can Measurement accuracy sea urchin creep speed.
Technical solution of the present invention is: a kind of sea urchin creep speed measuring method, it is characterized in that: sea urchin to be measured is put into the glass water vat that fills seawater, it is the foursquare grid of 5cm that the bottom of glass water vat is provided with the length of side, directly over the glass water vat, be provided with camera, motion process to sea urchin is taken, in the video of taking, choose sea urchin along one section video of rectilinear creeping, the first frame and last frame picture to this section video carry out sectional drawing, and two width of cloth sectional drawings are superimposed, utilize image measurement software to calculate the move distance L of sea urchin as reference with grid, the run duration T of the time interval calculating sea urchin of the first frame picture and last frame picture by intercepting, calculate the creep speed V=L/T of sea urchin, at least choose three sections sea urchins along the video of rectilinear creeping, and utilize said method to calculate each creep speed, average.
The present invention compares with prior art, has following advantage:
Sea urchin creep speed measuring method disclosed in this invention, easy to operate, simple, this method is by means of apparatus for making a video recording and image measurement software, can measure very accurately creep distance and the crawl time of sea urchin, and calculate the creep speed of sea urchin according to speed formula.In whole measuring process, sea urchin can not be subject to any chemical affect or physical injury fully in the raw, and the sea urchin after measuring is put in the nature seawater, can recover at once to move and ingest, and does not affect its self-sow.Therefore this method has possessed safely, measures accurately, and the advantages such as simple to operate, convenient and good reproducibility are for halobiontic creep speed measurement provides brand-new thinking.
Description of drawings
Fig. 1 is the picture sectional drawing of sea urchin when beginning rectilinear motion.
Picture sectional drawing when Fig. 2 is sea urchin end rectilinear motion.
Fig. 3 is the spliced map that sea urchin begins and finish straight-line two width of cloth sectional drawings.
Embodiment
Below in conjunction with description of drawings the specific embodiment of the present invention.
The sea urchin of at first will living is put into the glass water vat that seawater is housed, be provided with the square net that the length of side is 5cm in the bottom of glass water vat, directly over the glass water vat, be provided with camera, utilize camera that the motion process of sea urchin is taken, and utilize video jukebox software to play this section video, choose sea urchin along one section video of rectilinear creeping, the first frame (beginning rectilinear creeping to this section video, as shown in Figure 1) and last frame (finish rectilinear creeping, picture as shown in Figure 2) carries out sectional drawing, then utilize image processing software to be superimposed (as shown in Figure 3) in this two width of cloth picture, in same figure, show simultaneously sea urchin and begin two images of creeping and finishing to creep, then utilize image measurement software with the grid in the picture as object of reference, calculate the move distance L of sea urchin; Then calculate the first frame picture intercept and the time interval between the last frame picture, run duration T for sea urchin, the calculating of the run duration T here is for more accurate, here adopt the interval frame number between the first frame and the last frame divided by the mode of video camera per second record frame number time T to be calculated, then utilize speed formula V=L/T to calculate the straight-line speed of this sea urchin;
Repeat according to the method described above at least three operations, calculate respectively the straight-line velocity amplitude of sea urchin each time, then average.
Concrete measurement result is as shown in table 1.
