Description
Technical Field
The invention relates to the technical field of Xishi tongue culture, in particular to a maturation promoting method for culturing Xishi tongue parent shellfish by using pond algae.
Background
The western tongue is large-scale bivalve shellfish buried in shallow sea, and is used for eating unicellular algae and organic debris in water, commonly called as high-ranked imperial concubine snail. The Xishi tongue is large, high in meat content, tender and delicious in meat quality and rich in nutrition, and is a popular and rare edible shellfish. In recent years, the demand of the tongue of western province is increasing, and various predatory fishing (such as electric trawling, harrowing and other operation modes) lead to sharp reduction of yield and serious damage to resources. Therefore, the resource protection of the tongue of the western-style application is extremely important, the artificial seedling and breeding research of the tongue of the western-style application is an effective way for solving the current resource shortage, and the key of the artificial seedling is to obtain the mature parent shellfish of the tongue of the western-style application and hasten the parturition and discharge the sperm and egg. The traditional method for promoting the maturation of the tongue parent shell in Xishi mainly comprises the following steps: 1) Ripening is promoted by feeding artificially cultured unicellular algae; 2) Meanwhile, the water temperature is adjusted to promote the ripening. However, more manpower and material resources are needed for artificially culturing the unicellular algae, the growth of the algae is often greatly influenced by weather, the supply of the algae cannot be ensured, in addition, the artificially cultured unicellular algae is fed in a single variety, the nutrition is not comprehensive after the tongue is fed by the western medicine, and the maturation of the gonad of the tongue is not facilitated; and a large amount of energy is consumed for regulating and controlling the water temperature, and the production concept of low carbon and emission reduction is not met.
Disclosure of Invention
Based on the above discussion, the invention provides a maturation promoting method for culturing Xishi tongue parent shellfish by using shrimp pond algae, which realizes the maturation promoting effect of the Xishi tongue parent shellfish by using the shrimp pond algae and organic debris in a shrimp pond as bait of the Xishi tongue without regulating and controlling water temperature under natural conditions.
In order to achieve the purpose, the invention provides the following scheme:
the invention provides a ripening method for cultivating Xishi lingual parent shellfish by using pond algae, which comprises the following steps:
putting the Xishi tongue parent shellfish into a culture pond for ripening cultivation, and adding shrimp pond water into the culture pond to reach the height of a drain pipe;
the daily management specifically comprises the following steps: changing water 1/2 every morning, using water pump (2 inch water pump, flow rate is 15 m) 3 Per hour) pumping the shrimp pond water to the original water depth; directly extracting the shrimp pond water in the afternoon, adding the shrimp pond water into the culture pond, and continuously convecting the pond water; the surface was cleaned periodically for a layer of sand.
Further, the stocking density of the parent shell of the Xishi tongue is 15-18 per meter 2 。
Further, the convection time is 12-18 minutes.
Further, the surface sand layer was washed every 5 days.
Further, the shrimp pond water is water in an aquaculture pond for feeding prawns.
Further, the shrimp pond water contains green algae, diatoms and chrysophytes and organic debris.
The green algae, diatoms and chrysophytes and organic debris are all nutrients that facilitate ingestion by the tongue in western applications.
The prawn culture pond specifically comprises: laying a special film for cultivation at the bottom of the shrimp pond, and respectively placing waterwheel type automatic aerators on opposite corners of the pond; cleaning and sterilizing shrimp pond, adding seawater filtered by coarse sand, and applying inorganic nutritive salt for culturing algae, wherein the application amount is compound fertilizer (total nutrient is more than or equal to 45%, N-P) 2 O 5 -K 2 O＝14-16-15)12-18g/m 3 Sodium silicate (Na) 2 SiO 3 )1-1.5g/m 3 Starting an aerator to fully mix the pond water with the nutritive salt; culturing for 7-8 days to make the algae in the shrimp pond grow up, and putting the Penaeus vannamei Boone fry when the pond water reaches a certain transparency. The shrimp pond management is carried out according to the following modes: adding nutrient salt for algae growth 10-15 days after shrimp larvae release, wherein the adding amount of the nutrient salt is compound fertilizer (total nutrient is more than or equal to 45%, N-P 2 O 5 -K 2 O＝14-16-15)4-6g/m 3 0.3-0.5g/m of sodium silicate 3 (ii) a The residual bait left by feeding the shrimp feed and the excrement excreted along with the growth of the prawn individuals increase later, and the residual bait and the excrement of the prawns can be used as nutrient components of the algae; the aerator is started for 2 hours in the morning and afternoon respectively every day.
The invention discloses the following technical effects:
(1) The unicellular algae growing in the shrimp pond comprise green algae, diatom and chrysophyceae, are various in variety, and also comprise organic debris, which are high-quality biological baits for Xishi tongue, and meanwhile, the growth of the algae is slightly influenced by weather. Therefore, when the parent spat of the Xishi tongue is cultured, the shrimp pond algae and the organic debris are mainly fed, the nutrition is comprehensive, the Xishi tongue can be promoted to quickly mature, the sperm and egg can be discharged, and the sperm and egg discharge amount can be increased. And after the parent shellfish discharges the sperms and the eggs for the first time, the gonads of the parent shellfish can mature again to discharge the sperms and the eggs after a short period of intensive culture.
(2) The method for culturing the Xishi tongue parent shellfish is simple and convenient to operate, the technology is easy to master, manpower and material resources can be saved, and the production cost is reduced.
