Description
Technical Field
the utility model relates to a fish egg sample live body separator.
Background
In research studies on fishery resources and fish spawning sites, it is necessary to collect fish eggs and fish larvae samples in addition to fish samples of different specifications and ages to estimate the spawning site location, early resource occurrence, resource proliferation, spawning scale of various fishes, and the like. Most of fishes are fertilized in vitro, that is, under the condition that the ecological environment condition of a spawning site meets the breeding condition, male and female adult fishes chase after each other under the action of the breeding physiological hormone, mature eggs and sperms are removed from the body to finish fertilization, fertilized eggs are hatched in water, and the individual development process is started. The morphological structure properties of mature eggs and fertilized eggs of different fishes are different. According to the floating property, the eggs are divided into drifting eggs, floating eggs, sinking eggs and viscid eggs, and meanwhile, the eggs are distinguished by size and specification, mature eggs are spherical, and the diameters of the mature eggs are generally different from 0.5 to 6.0 mm. For floating eggs and floating eggs (floating eggs for short), because the eggs and the fries do not have swimming capability, namely the eggs and the fries can only float and descend or diffuse along the water flow from a breeding area of a spawning ground in a river or lake reservoir, the rising water flow enables the egg membranes to continuously absorb water and expand in the floating process, the egg diameter is increased, embryos are gradually hatched and developed, finally the eggs are broken into membranes and grow to the fries which are hatched initially, and the activities of active swimming, bait-pulling and the like can not be carried out until fins and swim bladders exist. The fish egg is spherical in the living state in water, and the size of the egg diameter is an important index for collecting and classifying and identifying fish egg samples. The special standard collecting net for roe and fry survey is used for collecting roe and fry hatched fry in the direction opposite to water flow, and can collect various roe and fry with the egg diameter over 0.5mm in water. And the acquisition net is used for positioning and acquiring samples at regular time during investigation. In the breeding season of fishes in rivers and lakes, the breeding season is mostly concentrated in spring and summer, fish eggs and fish fries of various fishes often occur simultaneously, collected samples are mixed samples of various fishes, and suspended matters or floating objects in water are also included. In the investigation field, samples and sundries carried by the samples are fished out from a collecting net and placed into a sample container, the sundries visible to the naked eye are picked out and discarded, and then primary treatment such as roe and fry sample shape observation, sampling counting and the like is carried out, but the work such as living body separation, measurement, classification, counting, statistical treatment and the like on various fish roes is difficult to carry out on the field. Meanwhile, as the egg membranes of the roes are thin after swelling and easy to break, the roes are easy to damage by manual shoveling and scooping and batch classification treatment, time and labor are wasted, and the roes are easy to die after leaving water. The field investigation field conditions are simple and crude, the samples cannot be stored after living body separation and fine treatment, at present, only part of mixed samples (formalin or alcohol fixing solution) can be manually picked up and extracted for fixing, and the mixed samples are taken back to a laboratory for further classification identification and statistics, while the fixed roe samples are dead, the color of roes is faded, the shape of roes is changed, the diameter of roes is changed, and the information data of living body observation classification identification is lost.
