Abstract
The invention relates to a method for breeding blood parrot fish. The method comprises the following steps of: starting from selection of parent fish; selecting cichlasoma citrinellum at the age of 2.2 +/- 0.3 years and with the weight of 221.12 +/- 10.52 g as a male parent; selecting cichlasoma synspilum at the age of 2.3 +/- 0.2 years and with the weight of 166.51 +/- 16.78 g as a female parent; incubating the produced roe under the conditions of water temperature of between 28 and 30 DEG C, the pH value of 7.5 to 8 and oxygen capacity in each liter of water of 4 to 5, wherein the incubating rate is over 80 percent; feeding the incubated fries according to different body lengths, weight and time; and paying attention to screening the fries with different growth speeds to maintain the consistency of the fries and enable the fries with different sizes to grow rapidly, so that the survival rate of the fries is over 75 percent.
Description
Technical field
The present invention relates to the hatching m of a kind of pet fish fry, relate in particular to the hatching m of a kind of blood parrot fry.
Background technology
The blood parrot fish is unintentionally after supporting Red Devil fish and purplish red burner fish together, the fantastic new fingerling of a group of generation.Because this fingerling is not the species that natural world exists, so incubation rate and survival rate all are the difficult points of breeding of blood parrot fish.
CN200610171034.2 discloses the propagation method of a kind of blood parrot fish, selects fiery crane fish for maternal, and purplish red burner fish is male parent, and a tail raun and a tail milter match, and yield rate can reach more than 90%.
Summary of the invention
The mating system that the purpose of this invention is to provide a kind of blood parrot fish, start with from the seed selection of parent population, attention is screened the different fry of growth rate, keeps the uniformity of fry and the fry Fast Growth of different size, so that the survival rate of the incubation rate of fish-egg and fry significantly improves.
The mating system of a kind of blood parrot fish, concrete steps are as follows:
1) selected the age of a fish 2.2 ± 0.3 years, the Red Devil fish of body weight 221.12 ± 10.52g is male parent; Selected the age of a fish 2.3 ± 0.2 years, the purplish red burner fish of body weight 166.51 ± 16.78g is maternal;
2) waited to lay eggs front 1 month, with step 1) a pair of parent population selected except behind the tooth in cultivating the pond, and examine the situation of every group of parent population, for what fight for a long time between the parent population, again pairing after the taking-up, the water temperature in the pond is 28-32 degree centigrade, pH7.5-8;
3) take fresh shrimp as the parent population feed, each throws 8 of every mornings and 5 PM once, and the input amount of feed is 7%. of parent population gross weight;
4) tile is put into the cultivation cylinder, water temperature is controlled at 29-31 degree centigrade, and the oxygen capacity in every premium on currency is 4-5, and parent population is laid eggs at tile;
5) there is product the tile of fish-egg to place the hatching house, water temperature 28-30 degree centigrade, pH7.5-8, the oxygen capacity in every premium on currency is 4-5;
6) 1000 tail left and right sides steps 5) fry that hatched is placed in the culture vessel that volume is the 1.5-2 cubic meter, the artemia nauplii of throwing something and feeding, each feeding volume is the 1.8g/1000 tail, regularly throw something and feed 3 time in 8:00,12:00 and 17:00 every day;
7) when fry grows to the long 1cm of body, according to the throw something and feed high protein fry feed of CP 〉=45% of 6% of body weight, change water 1/3-1/2 container volume every day;
8) fry rearing is after 25 days, to grow to fry about 1.5cm, to move into volume be that the seed of 1.5-2 cubic meter is supported in the container temporarily, fry in each container is about 1000 tails, and regularly throws something and feeds 4 times in 8:00,12:00,14:00 and 17:00 every day, until grow to the above juvenile fish of 3cm.
Step 6) to 8) cultivating process in, add copper sulphate as the fungus-resistant agent, water temperature is controlled at 29-31 degree centigrade, pH7.5-8, the oxygen capacity in every premium on currency is 4-5.
Cultivate 24 hours maintenance substantial light photographs in the container, intensity of illumination 1000lx.
The beneficial effect that technical solution of the present invention realizes:
The invention provides the mating system of a kind of blood parrot fish, start with from the selection of parent population, selected the age of a fish 2.2 ± 0.3 years, the Red Devil fish of body weight 221.12 ± 10.52g is male parent; Selected the age of a fish 2.3 ± 0.2 years, the purplish red burner fish of body weight 166.51 ± 16.78g is maternal, produce fish-egg at water temperature 28-30 degree centigrade, pH7.5-8, the oxygen capacity in every premium on currency is to hatch under the 4-5 condition, the incubation rate of fish-egg surpasses 80%.
Again the fry through hatching is carried out feeding by different body length, weight and time, note the different fry of growth rate is screened, keep the uniformity of fry and the fry Fast Growth of different size, so that the survival rate of fry surpasses 75%.
