Abstract
The invention relates to a method for cultivating glyptosternum maculatum fries and fingerlings through artificial feed. In an indoor cement pool, clean water resources from rivers are utilized, micro water flow is controlled through manpower, manual mixed feed is provided for feeding, and fries hatched from germ cells are cultivated to fingerlings 3cm in length. The rate of survival of the glyptosternum maculatum fries which live for 2-3 days to be fingerlings which are 3cm long is more than 80%.
Description
Technical field
The present invention relates to a kind of method that adopts artificial feed to cultivate blackspot Yuan Select-Committee fry and fingerling, belong to fish fry and nurture of fish fingerlings technical field.
Background technology
Fry and nurture of fish fingerlings are the important steps that Technique in Fishes is bred.At present, most fish can be by fishing for plankton or artificial culture plankton as the food in fry stage at natural water, and the minority fish fry stage is used natural bait, and the fingerling stage adopts the method for artifical compound feed to cultivate seed.All there is following shortcoming in two kinds of methods: 1. the quality of bait and quantity are difficult to guarantee; 2. the harmful animal that natural bait may carry and causal organism easily cause fry morbidity; In addition, in highlands, because weather is changeable, water temperature is on the low side all the year round, the reason the such as day and night temperature difference is large, and in water body, food organisms are very poor, and rugged environment condition is also not suitable for a large amount of food organisms of artificial culture.
The former Select-Committee of blackspot be one way of life in the Yarlung Zangbo River, Tibet, the Select-Committee section fish of upstream (height above sea level 2800～4200m), its organ of ingesting is positioned at the head outside of belly, to permit suction and to draw together food mode pickuping food, fry and fingerling stage be take periphyton as food, and are not suitable for ingesting and live in the plankton in water body.Adopting said method to cultivate seed is all difficult to successfully.
Up to now, there is not yet both at home and abroad relevant blackspot Yuan Select-Committee fry and fingerling artificial culturing method research report, patent or invention.
Summary of the invention
At indoor cement pit, utilize healthy stream water source, Artificial Control miniflow water, the artifical compound feed of feeding, is the fingerling of total length 3cm by the fry rearing of hatching from fertilized egg.
Be applicable to an artificial culturing method for blackspot Yuan Select-Committee seed, basic demand and the incubation step of its infrastructure are as follows:
(1) infrastructure
Cultivate pond: cultivate pond and should build in indoor.Cultivating pond is rectangle cement pit, long 3～4m, and wide 1.0～1.2m, high 40～50cm, at the bottom of pond, water inlet is compared with the high 2～3cm in water side.Chi Jiao is arc fillet, smooth at the bottom of pool wall and pond.
Sanctuary: make somebody a mere figurehead and put the cobble of diameter 10cm left and right as the sanctuary of fry and fingerling at the cement pit longitudinal axis with along longwell.
Enter pumping equipment: at the bottom of cultivating pond, pond, there is water inlet pipe higher one end; At the bottom of pond, there is the drainpipe that can regulate water level lower one end, and close eye screen cloth sealing for drainpipe delivery port, avoids fry and fingerling to escape.
(2) water source requires:
River natural water source.The floating thing in water with silk cover filtering, is removed in water source before entering cistern.Water source is clean, without poisonous and harmful substance; More than transparency 100cm, more than dissolved oxygen 7mg/L.
(3) preparation before cultivation:
1) put first 7 days in a suitable place to breed, to cultivating pond, clear up, rinse, sterilize.Specific practice: will cultivate pond cleaning totally, by clean water, repeatedly rinse 3～4 times,
2) at the cement pit longitudinal axis with along the built on stilts diameter 10cm left and right of putting of longwell, please wash clean cobble as the sanctuary of fry and fingerling.
3) pour water to 30～40cm, adding salt to the salinity of cultivating water in pond is 5%, soaks and drains after 24 hours, then rinse 2 times by clean water, then water level is controlled to 20cm, and keeps miniflow water 5～6 days, can put seedling.
(4) offspring seed cultivation method:
1) the yolk seedling of 2-3 age in days is evenly put into and cultivated pond along the cobble of putting, breeding density is 2000～2500 tails/m
2.
2) blackspot Yuan Select-Committee fry is in early days from the source property trophophase, relies on self yolk that nutrition is provided.This stage only should be noted that water quality and water temperature change, without the feed of throwing something and feeding.
3) when yolk also remains 1/5, when minority fry starts to appear at cobble and shows to lick behavior, show that fry closes to an end from the nutrition of source property, start to turn to exogenous nutrition, the artifical compound feed of should throwing something and feeding in time.Throw something and feed before feed, the ight soil of should be thrown something and fed last time remaining residual bait and fry is thrown something and fed after removing totally more at every turn.
4) the whole nurturing period requires to keep water quality pure and fresh, and water temperature, can not be over 15 ℃ between 12～14 ℃.
5) cultivate later stage fingerling be easy to get trichodinasis and chilodoniasis, adopt the formalin solution of 20ppm to soak 3～5min, can reach effective result for the treatment of.
Adopt fry that the present invention cultivates blackspot Yuan Select-Committee 2～3 ages in days to the survival rate of 3cm fingerling to reach more than 80%.
