Description
Technical field
The present invention relates to a kind of fish movement metabolism and swimming behavior synchronous recording determinator.
Background technology
Metabolism is the most basic vital movement of animal body, its metabolism intensity and active state, and the amount of exercise size is closely related.The mensuration of metabolic rate is the basic skills of metabolism research, is the important means of estimating metaboilic level and exercise intensity.Because fish inhabit water body environment, the mensuration of its metabolic rate generally all adopts in the respiratory chamber of a sealing by measuring the indirect determination method that its consumption rate is converted into metabolic rate again.Initial mensuration is that the experiment fish is placed the container (respiratory chamber) of a sealing, and the water body in the container does not flow, and not with external world's exchange, calculates the metabolic rate (document 1) of unit interval by the difference of the dissolved oxygen content of water body before and after the mensuration.This method is breathed the influence that produces because of the reduction of water body dissolved oxygen in the closed container itself to fish and bigger error occurred.Existing respiration monitoring device is on the basis of original airtight respiratory chamber, adopt water inlet and water output duct to make the water body in the respiratory chamber keep certain exchange rate with the external world, the dissolved oxygen of water body remains on certain level in the respiratory chamber thereby keep, and the difference of the dissolved oxygen content of the water body by measuring water inlet and water outlet is calculated the metabolic rate (document 2) of fish.But said method all can only be measured the Standard Metabolism (on an empty stomach, inactive state) of fish or conventional metabolism (on an empty stomach, daily exercise state), can not measure the metabolism Strength Changes under the different motion state.
Different its swimming behaviors of fish and kinetic characteristic difference.Behavioral indicator relevant with swimming exercise such as tail fin hunting frequency, amplitude of fluctuation, swimming direction, track, speed etc. all can obtain by video recording and video analysis in the open architecture test tank of sealing or flowing water.Adopt the transparent tank of hydrostatic can the observation analysis hydrostatic condition under the swimming behaviors (document 3) of fish, adopt annular circulating water chennel design different in flow rate can measure the swimming behavior of fish under the different motion state, but the actual activity zone of experiment fish is defined to a part of space of tank, when flow velocity is excessive, the experiment fish can be intercepted at the downstream and block on the grid, can't observe its further behavior reaction (document 4).Because above-mentioned experimental trough is open by design, can not determination experiment during the metabolic rates of fish.
The behavior of animal is the external manifestation of its physiological function.Physiological parameter combined with behavioral indicator, and to analyze be development trend and research one of focus of modern behaviouristics research.The swimming behavior of fish and its activity metabolism have substantial connection, and its Changing Pattern is found out in logical quantitative analysis to both sides relation, help to inquire into the physiological mechanisms that the fish behavior changes.For this reason, the research method that at first must foundation can measure activity metabolism and swimming behavior simultaneously.

Fish movement metabolism as shown in Figure 1 and swimming behavior synchronous recording determinator comprise cylinder shape tank 1, the loam cake 2 made by transparent material, have sealing ring 9 to form airtight tank between tank 1 top and the loam cake 2, and there is bubble tap 6 at the loam cake middle part.Tank 1 one sides are connected with water inlet pipe 3, and opposite side is connected with outlet pipe 4, and flow regulator 5 is arranged on the water inlet pipe 3.Can regulate inflow by flow regulator 5, the water body dissolved oxygen maintains on certain level in the holding device.The upside of tank 1 and the outside are respectively equipped with video camera 8.In tank central authorities one cylinder 10 is arranged, the space between cylinder 10 and the sink outer walls forms water annulus 11; Bottom in cylinder 10 central authorities is equipped with current and is produced and adjusting device 7.As shown in Figure 2, this current produce and arrangements for speed regulation 7 are made up of two immersible pumps 71 and two sparge pipes 72 being connected with two immersible pumps respectively.Immersible pump 71 is an adjustable speed formula immersible pump, places in the cylinder 10; Sparge pipe 72 radially is fixed in water annulus 11 bottoms in line by extending out to water annulus 11 in the cylinder 10, and every sparge pipe 72 monolateral has a plurality of apopores, and the water spraying direction of two sparge pipes 72 is opposite.The power line of immersible pump 71 passes loam cake 2 and is connected with external power source.
During work, the hydraulic pressure that immersible pump 71 produces by the ejection of the apopore on the sparge pipe 72, because these two sparge pipe water spraying directions are opposite, thereby forms the circulation that flow velocity is relatively stable and be evenly distributed with water, and the big I of flow velocity is regulated by immersible pump.By the flow velocity of control water annulus 11, make the experiment fish produce the amount of exercise of varying strength, but measure the metabolic rate of the dissolved oxygen content of water inlet and water outlet with regard to the experiment with computing fish because of top stream.Because agent structure adopts transparent material to make, thereby the swimming behavior of shooting or picture recording record experiment simultaneously fish be can pass through, thereby activity metabolism and the synchronous purpose of measuring of swimming behavior reached.
Below be the result that 2 examples utilize this fish movement metabolism and swimming behavior synchronous recording determinator to test:
1, with the red fin pond crucian carp of the about 100g of body weight be experiment material to measure it with this device be 0,0.1,0.3 at flow velocity, the consumption rate under the 0.5m/s4 kind condition, and record analysis experiment fish tail fin hunting frequency.The result shows, along with the increase of flow velocity, red fin pond crucian carp consumption rate increases, but flow velocity when reaching 0.5m/s consumption rate no longer increase on the contrary and descend to some extent; The tail fin hunting frequency is directly proportional with consumption rate, is identical variation tendency with flow velocity, proves that red fin pond crucian carp increases because of adverse current swimming strengthens the tail fin hunting frequency with flow velocity in the certain flow rate scope, and specific consumption increases, so metabolic rate improves.When flow velocity was excessive, red fin crucian carp adverse current swimming exercise weakened, and specific consumption reduces, so consumption rate descends.
2,, measure it under the 0.3m/s flow velocity, the variation of activity metabolism and swimming behavior in 24 hours with same experiment material.The result showed that red fin pond crucian carp consumption rate and tail fin hunting frequency raise gradually in initial 3 hours, reached maximum at 3 hours, and descending subsequently also maintains on the certain level for a long time.During proof experiment beginning, because red fin pond crucian carp does not adapt to this flow velocity very much, the adverse current swimming exercise reduces, and tail fin hunting frequency and consumption rate show reduced levels.Along with the prolongation of time, the red fin pond crucian carp adverse current swimming exercise amount that progressively adapts to increases, and tail fin hunting frequency and consumption rate descend to some extent because of tired after reaching maximum, keep certain swimming state and amount of exercise in the long period subsequently.
The foregoing description is a preferred implementation of the present invention; but embodiments of the present invention are not restricted to the described embodiments; other any do not deviate from change, the modification done under spiritual essence of the present invention and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within protection scope of the present invention.
