Description
Technical field
The utility model belongs to technical field of aquaculture, particularly relates to a kind of determinator of online fish prelarva consumption rate.
Background technology
Fish are in the biological oxidation process produce power of various metabolism, and the energy metabolism of body is directly proportional with their oxygen consumption, and consumption rate can be weighed the intensity of fish body metabolism.In general, consumption rate can be divided into basic consumption rate and movable consumption rate.The basis consumption rate is meant the oxygen demand that fish show when the basal metabolism situation.Fish must be remained under the rest state during mensuration, get rid of muscular movement, ingest, interference such as thermal stimulus.Certainly for fish, this rest state is relative, can be very unstable.Movable consumption rate is meant the oxygen demand of fish when the comings and goings state.Consumption rate is under movable and excited influence, and it is bigger to fluctuate, and activity is strong more, and oxygen consumption is high more, reaches the highest consumption rate at last.
The fish consumption rate is subjected to the influence of many inherences and external factor, comprises temperature, salinity, body weight, active state etc.No matter be basic consumption rate or activity consumption rate, all be subjected to temperature effect easily.Fish is a poikilotherm, the temperature of water environment directly influences the body temperature of fish, and then influence the active of enzyme and by enzymatic biooxidation reactions, so temperature is remarkable to the consumption rate influence of fish, in certain temperature range, along with water temperature raises, the fish consumption rate also increases thereupon, but when water temperature was elevated to a certain degree, its consumption rate descended on the contrary.As grass carp seed then, when water temperature was increased to 28 ℃, consumption rate was the highest; After water temperature surpassed 28 ℃, its consumption rate began to reduce on the contrary.Definite relation between fish consumption rate and temperature, different according to the kinds of fish, temperature that fish adapted to and excursion of environmental temperature etc.Salinity is to the influence of consumption rate, with the life habit of fish substantial connection arranged, therefore the reaction difference of various fishes.As live in crucian in the fresh water, when salinity slightly rises, consumption rate is increased; But when salinity continued to increase, consumption rate began again to descend.Salinity is high more, and it is many more to descend, if but be in for a long time in the water body of high salinity, its oxygen consumption can go up again gradually.Body weight has appreciable impact to the fish consumption rate, and the test of red Medaka fish is shown, along with the increase of body weight, the oxygen demand of per weight reduces very remarkable, and downward trend, and young fish is obvious.Fish are in when swimming, and oxygen consumption can increase with 10 factor usually, and the strong especially fish of minority swimming ability can increase by 15 times.In the ordinary course of things, the every increase of the swimming rate of fish 1 individual long unit, i.e. body length/second, oxygen consumption can be with about 2.3 factor increase.Fish are when swimming fast, and oxygen consumption can increase by 10～15 times, and the oxygen consumption of increase mainly is that the oxygen consumption of the fish gill is not significantly increased because the motion of muscle causes.
The assay method of fish consumption rate mainly contains 2 classes: a class is to adopt simple closed container, measure the oxygen amount that fish is consumed in the certain hour. such as adopting erlenmeyer flask to carry out, the fish prelarva is directly put into bottle, tighten bottle stopper, behind the airtight certain hour, open bottle stopper, with the water sample at the bottom of the soft rubber tube siphonage sucking-off bottle, measure the dissolved oxygen amount of water sample, compare calculating with the water sample of blank group, then can draw the oxygen demand of fish prelarva, then calculate consumption rate divided by the time. there are some shortcomings but measure with erlenmeyer flask, as after opening bottle stopper, water in the bottle contacts with oxygen, cause certain error easily, siphonage water intaking in addition, operation is also complicated. and another kind of is to adopt specially designed respiration monitoring device, can allow water in airtight respiration monitoring device, constantly circulate with different flow velocitys, the consumption of water oxygen level can replenish by injecting pure oxygen, make it keep original level, so just can observe the oxygen demand of measuring the activity metabolism that fish swim with friction speed for a long time. such as adopting the continuous-flow type device, water with certain velocity flow through respiratory chamber, because the breathing of fish, the flow through oxygen in water of respiratory chamber of consumption, so by measuring the dissolved oxygen of respiratory chamber water inlet and delivery port, the flow velocity of combination water and flow, can calculate the consumption rate of experiment fish. but this airtight respirometer, to having relatively high expectations of manufacturing and designing.
Summary of the invention
