Description

Hehua fish sulturing method in rice field

The present invention relates to agricultural or aquaculture field, particularly a kind of method of utilizing the paddy field cultured fishes.

Rice field fish culture, a kind of mode as multi-storied agriculture has been caused attention, and the successful report of the rice field fish culture utilized is also arranged in recent years.But in disclosed rice field fish culture report, only be the water surface that utilizes the rice field, promptly simply utilize the rice field to replace the pond, carry out original putting in a suitable place to breed.Known rice field fish culture method lacks the management of science, and the fry kind is poor, and at the bottom of the survival rate, output is not high.

The object of the present invention is to provide a kind of rice field fish culture method of science, this method is selected the fry kind of high-quality for use according to the characteristic in rice field itself, rationally control the water yield, water temperature, oxygen and feed intake and feed, have survival rate and output height, the quality better of fish, characteristics such as remarkable in economical benefits.

The scheme that the object of the invention realizes is that step is carried out by the following method:

1. seed selection kind, the first generation fish of selecting for use nonlocal male carp and local female carp to hybridize are hybridized second generation seedling that the first generation fish breeding that cultivates for culturing fry with male carp in this locality and nonlocal female carp again;

2. put in a suitable place to breed, after the early rice rice transplanting 7-15 days, throw in fry behind the mud sediment, treat to trip out after the early rice grouting fish move on in the rice field put in a suitable place to breed, trip out fry after the semilate rice grouting and move on to late rice and put in a suitable place to breed, get final product harvest after the late rice grouting;

3. the control of the water yield, water temperature, oxygen, temperature are 5-10 when spending, based on fixing water, circulating water is auxilliary, and the depth of water keeps 3-7 cun, or temperature is that 10-15 is when spending, based on circulating water, indirect securement water, the depth of water keeps 5-9 cun, or temperature is 15-25 when spending, and all adopts circulating water, by quickening the mobile cooling of water, the depth of water keeps 6-11 cun, or temperature when above, adopts circulating water at 25 degree, and the depth of water remains on 7-12 cun;

4. the feeding that feeds intake, it is main adopting between whole feeding period and getting the rice pollen that food falls into the water, and is aided with the feeding method of the fish meal of throwing something and feeding.

Fry injected volume of the present invention is looked the girth of a garment decision in field.The input fry 200-300 tail of per mu yield paddy more than 900 jin; The input fry 150-200 tail of per mu yield paddy more than 800 jin; The input fry 100-150 tail that per mu yield paddy is about 600 jin.

The fingerling that the present invention preferentially selects for use the Changjiang river carp and the hybridization of local carp to be cultivated, specifically be that the local female carp about a year hybridizes the male fish that and hybridizes the second generation Hehua fish seedling that the female fish breeding that is cultivated with the female carp of male carp in this locality and the Changjiang river again with the male carp in the Changjiang river of the age of a fish about 1 year and the age of a fish, the fish hypertrophy that adopts this kind fry to raise is sturdy, every tail can be grown about 6 liang, the output height, meat is good.

The present invention adopts the following feeding method that specifically feeds intake to feed: fry is thrown in the early rice field and begins after one month for the ichthyophagy feed, time 15-20 days, before the seedlings of cereal crops flowering 10-15 days are jejunitas, the edible pollen that falls into the water of fry after early rice standing grain pollen comes out, jejunitas during the rice field in the commentaries on classics, after coming out, semilate rice standing grain pollen gets the anthophagy powder, and jejunitas during the commentaries on classics late rice, after coming out, late rice standing grain pollen gets the anthophagy powder.

The present invention selects for use the Hehua fish of special food seedlings of cereal crops pollen to raise in the rice field, and utilizing seedlings of cereal crops pollen is main feed, has changed the mode that tradition feeds intake and breeds fish, and has reduced Financial cost.At the characteristics in this fish and rice field, adopt the management method of science simultaneously, improved the yield and quality of fish effectively, improved economic benefit.

Embodiment:

Present embodiment is an example with backlands district, osmanthus, Guangxi, and the male fish of adopting the female carp of the male carp in the Changjiang river and the Guilin at an age at an age to hybridize hybridizes the second generation Hehua fish seedling that the female fish breeding that is cultivated with the female carp of male carp in Guilin and the Changjiang river again.When growing seedlings, be the fingerling of cultivating then, put into the rice field earlier, before the standing grain flower comes out, play fish and put in a suitable place to breed by male, the female minute pool, its purpose one is not allow the fingerling mating produce son, in order to avoid influence quality, the 2nd, in a single day fingerling has been eaten the standing grain flower and will have been finalized the design by precocity, childlike, the fry poor growth of output.The paddy field of selecting for use of growing seedlings, the rough field of ploughing early winter (ploughing a field for the first time is plough, and multiple for the second time plough is named rough field) removes a little lime disinfections, treat winter end the more rough field of ploughing once after, discharge water about 1 chi, loosen branch around the field and lay eggs for a fish, put up the cloudy canopy of isosceles triangle simultaneously, each 8 chi of cloudy canopy length and width, dried up 1 chi.Fingerling was thrown in after 10 days in rough field, and about about one month, during to the early rice rice transplanting, the ovum of fingerling output was hatched fry and grown to 1 centimeter.When early rice rice transplanting about 10 days, be about to fry behind the mud sediment of rice field and throw in the field, throw in 200 tails for every mu.After the Ching Ming Festival, temperature is lower behind the input fry, and on average about 8 degree, keep about 5 cun of the depth of waters this moment, and require five days fixedly water, two days circulating waters; When temperature gos up when 10-15 spends, keep about 6 cun of the depth of waters, require five days circulating waters, two days fixing water; When temperature rises to 15-25 and spends, keep about 9 cun of the depth of waters, and require whole circulating waters, by quickening the mobile cooling of water; When temperature more than 25 degree, keep about 10 cun of the depth of waters, all circulating waters are breeded fish and circulating water cooling fast by deep water.After throwing in fry, by followingly feed intake, jejunitas method feeds: fry is thrown in the field fish food feed of manually throwing something and feeding after month, time 15-20 days; Jejunitas to seedlings of cereal crops pollen 10-15 days before coming out, cause the fish sense hungry, treat that seedlings of cereal crops pollen comes out and falls into the water surface after, fish is sucked seedlings of cereal crops pollen desperately; When need draining cold field morning after the flowering of rice field, fry is gone to middle paddy field aquaculture, be the jejunitas phase this moment, fry is got the anthophagy powder after coming out to semilate rice seedlings of cereal crops pollen; The central rice field later stage goes to late rice with fish when needing draining, and this moment is jejunitas, comes out the back for the anthophagy powder until late rice seedlings of cereal crops pollen.Adopt so for food to jejunitas to the feeding method for food, fish will sturdy hypertrophy, the output height, and endoplasm is good.Can receive fish to the late rice grouting and put sale on market, this macrura reevesii is about 20 centimeters, and about 25 centimeters of waistline weighs about 8 liang.
