Bait " refer to dried silkworm chrysalis, pluck and mixed feed etc.；Quiet with dynamic band, " dead bait " activates, last excessively artificial to ingesting completely
Bait；Require feed intake timing, quantitative, location simultaneously；
(7), froglet is when raising and train 20-30 days, is allowed to dry water, and is proceeded to by every square metre of 60-80 density by the froglet of big specification
Grown frog pool is raised；Small dimension froglet still stays former pond to raise and train；Bait, indoor stereo, multilamellar boxes and baskets intensive cultivation are raised in employing；Rana nigromaculata is supported
Growing in plastic box and wooden case, carry out small-sized cultured output high, every square metre can cultivate hundreds of, typically from hatching to one-tenth
The frog, only needs five months；
(8), after froglet proceeds to grown frog pool, Rana nigromaculata food ration is big, and the speed of growth is accelerated, and is the important period forming commodity output,
Except well-off bait, Tinea Ranae metamorphosis need when becoming the frog to increase the feeding of animal fodder, mainly artificial culture fly larvae,
High protein, the live baits of high reproductive rate such as Lumbricus, blood worm, ball algae water flea；Froglet is active in water, can be supplied to essence and raise after five days
Material, for bean milk, egg yolk, water flea, water spinach, Fructus Lycopersici esculenti and hydroplankton；Additionally, on mound cultivating earthworm, as long as being close to every day
Evening, burst spilt the lime water that some concentration are 3-5% on mound, and Lumbricus i.e. can swarm out, and serves as frog bait；
(9), the frog is become to raise after one month, when frog body weight reaches 100 grams, stocking density every square metre 30, change into after two months
Every square metre of 10-15 is only；Raise through short-term again, the listing of the commodity frog can be become.
High density the most according to claim 1 concentrates the cultural method of stable breeding Rana nigromaculata, it is characterised in that described step (1)
In can lay bricks enclosure wall, also can enclose by net, general 1-1.2 rice is high；Depth of water 30-60 centimetre in pond, water central authorities or sunny side pile
Mound is for the land habitat of Rana nigromaculata, and accounts for the 1/3 of full pond；Grass or crops are planted on mound；Water put into a small amount of
Floatability pasture and water；It is used as to cultivate the pond of Tinea Ranae, only stays a small amount of land surface, log in for the froglet after metamorphosis；Tinea Ranae pond Yi Shui
Preferably, the pool wall gradient is the most slow, perches for Tinea Ranae for mud sump.
High density the most according to claim 1 concentrates the cultural method of stable breeding Rana nigromaculata, it is characterised in that described step (4)
In the most every ten thousand tails with 15 ripe eggs rub broken band water sprinkle feed 1-2 time.
High density the most according to claim 1 concentrates the cultural method of stable breeding Rana nigromaculata, it is characterised in that described step (6)
Middle charging time is: spring, autumn, summer between the lights or morning, fed intake 1-2 time every day, and feed intake will be one every time at noon
About hour, froglet eats up；The froglet daily ration, feeding quantity of body weight less than 50 grams answers the 6-8% of percentage of liveweight；The froglet that body weight is more than 100 grams,
Daily ration, feeding quantity answers the 8-10% of percentage of liveweight.
High density the most according to claim 1 concentrates the cultural method of stable breeding Rana nigromaculata, it is characterised in that described step (8)
In in the case of live bait deficiency, mixed fodder of can arranging in pairs or groups, as joined with rapeseed cake 60%, Testa oryzae 30%, Semen sojae atricolor powder 5%, fish flour 5%
Conjunction even results is preferable.
